  • Consumers’ Sustainable Consumption of Hybrid Cars: An Application of
           Goal-Framing Theory in the Pakistani Market

    • Free pre-print version: Loading...

      Abstract: Abstract The study examines the role of motivational factors required for the sustainable consumption of hybrid cars. The adoption of such cars significantly reduces the use of fossil fuel and hence, it is imperative to identify and understand which motivational factor is required to be promoted. Through convenience sampling technique a sample size of 309 hybrid car users was obtained and partial least squares-structural equation modeling (PLS-SEM) was applied to test the data for validity, reliability, and hypothesized relationships. The results supported the theory and found normative motivations as the strongest factor affecting sustainable consumption. The study discovered the importance of customers’ instrumental attributes and emotions for sustainable consumption. This study combines the motivational and personal components that must be promoted while advertising sustainable products. This is the first of its kind study using the Goal-Framing theory in the developing market settings. The study extended the concepts presented by the Goal-Framing theory (GFT). Overall, the observation of hybrid cars as sustainable products suggests that policymakers should focus on the motivational constructs independently and through the interplay in the promotional messages.

  • Measuring Connectivity of Pedestrian Street Networks in the Built
           Environment for Walking: A Space-Syntax Approach

    • Free pre-print version: Loading...

      Abstract: Abstract Network connectivity is an important aspect of the built environment. However, it rarely captures the attention of decision-makers while implementing pedestrian projects. In recent years, Space-Syntax (SS) analysis is gaining popularity among researchers due to its ability to clearly demonstrate the topological configuration of a physical network. This research carries out a connectivity analysis of 297 links across three pedestrian networks in Varanasi, India, thereby exploring the relationship between pedestrian volume, SS indices in the Indian context, and other built environment features, such as presence of sidewalk, right-of-way (ROW) and landuse area. Data collection includes developing a GIS database of the pedestrian network, 30-min pedestrian volume counts at various locations, and calculating SS connectivity measures from the configuration of the pedestrian networks. Resulting SS indices were analyzed with existing pedestrian volumes through correlation, stepwise multiple linear regression (MLR), and path models. Results of the analysis showed that the SS index ‘Normalized Angular Integration (NAIN)’ to be highly correlated with pedestrian volume (r = 0.57). Subsequently, the MLR and path models show a statistically significant relationship of pedestrian volume with NAIN, ROW, presence of sidewalk, and commercial area. ROW affects the pedestrian volume both directly and indirectly in a commercial area, thereby indicating a requirement for improving/providing walking facilities in such areas. The study concludes with practical implications for local authorities that highlight the importance of providing walking infrastructures at commercial streets having high connectivity. The study also shows the significance of NAIN as an effective measure of pedestrian street network connectivity.

  • The Role of Built Environment on Pedestrian Safety and Pedestrian Activity
           at Urban Signalized Intersections

    • Free pre-print version: Loading...

      Abstract: Abstract The present paper examines the role of the built environment on pedestrian-vehicular crashes, pedestrians’ risk perception, and pedestrians’ unsafe activities at the urban signalized junctions in the context of a developing nation. A conceptual framework is established to recognize the possible associations between the built environment, risk exposures, pedestrian activity, risk perception, and pedestrian crashes. The proposed research work is demonstrated with reference to the metropolitan city of Kolkata, India. The Negative binomial models are developed to study the association between the built environment and police-reported crashes. Likewise, to examine the role of the built environment on pedestrian risk perception Ordered logit models are developed. The study outcome shows that an increase in average vehicular speed by 10 km per hour at a junction is expected to increase the chance of pedestrian fatalities by 50%. With an increase in minor road width by one unit, pedestrian fatality risk is likely to rise by 7%. The lack of a pedestrian signal head is expected to increase pedestrians’ perceived risk by 1.2 times; whereas the absence of adequate sight distance is probable to increase pedestrians’ perceived risk by 2.3 times. Subsequently, a set of beta regression models are developed to examine the impact of the built environment on pedestrians’ unsafe activities. The outcomes confirm that ‘pedestrian’s usage of mobile phones while crossing’ (distraction) increases the possibility of pedestrian signal violation behavior by 1.7 times. Inaccessible zebra crossing and on-street parking are likely to increase pedestrians’ risky crossing behavior by 16% and by 14%, respectively.

  • Rear-End Conflict Variation at Signalized Intersections Under
           Non-lane-Based Traffic Condition

    • Free pre-print version: Loading...

      Abstract: Abstract Traffic conflict techniques (TCTs) are one of the most frequently used proactive surrogate safety measures which can be used to estimate traffic safety even before the occurrence of a crash. This study explores the variation in rear-end conflict with respect to signal timing and distance from stop lines at signalized intersections with non-lane-based behavior under mixed traffic conditions. More than 4500 vehicle trajectories were extracted for every 0.2-s interval using a semi-automatic tool from field-recorded video footage from two signalized intersections in India. Two popular surrogate safety measures, time to collision (TTC) and deceleration rate to avoid crash (DRAC), were used to identify critical interaction between different vehicle types at varying threshold values. The temporal variation of traffic conflict showed that the majority of conflicts are happening in the first half of red and green time, whereas more severe conflicts occurred at the beginning of red time. Two-wheelers and three-wheelers showed the highest lateral movement and aggressiveness, resulting in critical vehicle interactions closer to the stop line. Variation in conflict proportion based on lane type showed that smaller vehicles prefer curb-side lanes over median-side lanes. Temporal and spatial distribution of conflict based on vehicle type and conflict severity distribution gives a better understanding of how the signal timing influences traffic safety in non-lane-based mixed traffic conditions. These results can be used most beneficially for enhancing the safety and performance of signalized intersections in developing countries.

  • Freight Traffic Impacts and Logistics Inefficiencies in India: Policy
           Interventions and Solution Concepts for Sustainable City Logistics

    • Free pre-print version: Loading...

      Abstract: Abstract Freight traffic fulfils not only the business needs of a region to move goods between producers, manufacturers, and end consumers, but also creates a host of unintended environmental, social, and economic impacts. Despite its importance, freight traffic impacts and associated logistic inefficiencies are largely overlooked in the urban transport discussions in developing economies like India. This paper addresses this research gap by outlining the research progress related to freight transport in India and discusses the key problems related to freight system performance. The published literature in the last three decades (1990–2020), policy briefs and institutional reports are explored to summarize key findings and uncover thematic linkages. We categorize the inefficiencies in the freight system into four aspects: (i) long-haul trucking, (ii) last-mile logistics, (iii) freight distribution (inventory level), and (iv) policies and regulations. Apart from identifying the limitations in policy discourse, this paper also explores the possible solution concepts to improve efficiency in freight transport and mitigate the unintended negative externalities in urban areas. The overall conclusion is that increasing and improving infrastructure and equipment, technology and operations, and policy and regulations will go some way towards making freight more efficient in India and reducing congestion and emissions of air pollutants and GHG. The present paper can be expected to promote further freight research and effective policy instrument design in India.

  • Modeling Traffic Parameters Accounting for Platoon Characteristics on
           Multilane Highways

    • Free pre-print version: Loading...

      Abstract: Abstract Most vehicles on highways experience platoon congestion, primarily due to the impedance created by heavy vehicles (HVs). The platoon generated by the HVs directly impacts the smooth traffic flow conditions, affecting the travel time, speed, capacity, and level of service. The study aims to model and analyze the impact of HVs considering the platoon characteristics observed on Indian highways. A significant amount of traffic data, such as volume, speed, and time headway, was collected from highway sections using infra-red sensors. The average coefficient of variation of speed criteria was used as an indicator of variability (IoV) to estimate the critical time headway. The threshold value of critical time headway of 3 s was identified for classifying vehicles into non-platoon followers and platoon followers. The traffic speeds were modeled using the simultaneous equation approach. The speed–flow–density curves were developed for the two traffic regimes. The platoon regime results indicate that the percentage reduction in the speed at capacity, density at capacity, and traffic capacity was 10.8%, 13.5%, and 22.9%, respectively. Further, it was identified that the travel time at capacity increased by 10.6 s/Km under platoon conditions compared to non-platoon conditions. Consequently, the travel delay at capacity increased by 12.2%. The study shows that the traffic interaction under platooning conditions predominantly affects the traffic operational quality (level of service) and efficiency. The research findings emphasize the significance of considering the platoon dynamics under the influence of HVs to explain their impact on the macroscopic traffic flow characteristics.

  • Location Evaluation of Existing Park-and-Ride Facilities Along a Transit
           Corridor: A Case of Delhi MRTS

    • Free pre-print version: Loading...

      Abstract: Abstract The ever-rising urban sprawl is one of the key concerns of metropolitan cities around the world. The deterioration of public transport connectivity to the remote areas of the city influences people to use private vehicles. Many countries introduced a Park-and-Ride (P&R) system to control the use of private vehicles and improve access to the existing stations of public transport. To ensure a successful implementation of the P&R system in the city, it is essential to provide such facilities at appropriate locations. This study develops a checklist to evaluate the locations of existing P&R facilities and tests it over the P&R facilities near the metro stations of green line metro network of Delhi, the capital of India. The Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) is used in this study on the evaluated scores to determine the preference of the existing locations for P&R facilities. The results suggest that the preference of the locations decreases as it moves closer towards the city centre. The output of this study also recommends reducing the number of P&R facilities present along the green line corridor to improve the efficiency of the P&R system. The developed approach can prove to be an aid for urban planners, transportation authorities, and P&R operators to assess the suitability of a location for a P&R facility.

  • Development of a Systematic Methodology to Enhance the Safety of
           Vulnerable Road Users in Developing Countries

    • Free pre-print version: Loading...

      Abstract: Abstract Vulnerable road users (VRU) such as pedestrians, motorcyclists, and bicyclists, account for more than half of total road traffic fatalities in developing countries. In urban India, VRU consist of more than 80% of the fatalities. Although in Indian cities, the share of VRU is considerably high, suitable VRU-friendly facilities are not efficiently planned. In this context, the present paper aims to develop a systematic approach to enhance VRU safety at the urban intersection level in the context of a developing country. Using 6 years’ crash data (2011–2016) from “Kolkata Police”, India, the applicability of the present research framework is demonstrated. To examine the major risk factors associated with pedestrians, motorcyclists, and non-motorized transport users (NMT: bicycle, cycle-rickshaw, and hand-pull carts), three sets of crash prediction models are developed with the help of Poisson and negative binomial analysis. The study outcome reveals that vehicle volume and speed, inadequate sight distance, and the absence of designated bus stops significantly affect the likelihood of fatal pedestrian crashes. Alternatively, overspending and overtaking behavior by motorcyclists, and restricted sight distance increase the fatality risk of motorcyclists. Speed inconsistency between motorized and non-motorized vehicles, insufficient street lighting, and inadequate sight distance increase the risk of NMT users. The overall study outcomes specify the need for segregation between motorized traffic and VRU at urban intersections by providing dedicated lanes for VRU along with suitable crossing facilities; implementing signalization with a distinct phase for VRU. The study also highlights the importance of speed management measures in urban India.

  • The Who, When and Why of Uber Trips in Dhaka: A Study from Users’
           Perspective

    • Free pre-print version: Loading...

      Abstract: Abstract Growing travel demand and technological development provoke to enhance the share of ridehailing services within urban transportation sector in the developing countries. To keep pace with this flow, Uber service has been launched in Dhaka, Bangladesh and is getting popular to city dwellers. Despite this, very little information is available regarding the user groups, their trip characteristics and service quality of ridehailing in the context of developing countries. In addition to this, effects of such service on other modes and users’ view about service are at unexplored state which is important to ensure a sustainable and equitable transport system. This study intends to investigate these issues where questionnaire survey through face-to-face interview has been conducted among the Uber users of Dhaka using simple random sampling technique. The data are analyzed engaging descriptive statistics and statistical modeling. Results show that Uber is used by comparatively wealthy younger social groups despite they claim to pay more than other alternative modes even than the specified fare by Uber that put forward the issue of equity. In accordance with user’s opinion, better accessibility, safety, comfort and existence of emergency situation influence their decision to choose Uber instead other modes like CNG, taxi services etc. Uber users of Dhaka mainly share trips with their acquaintance ones. Moreover most of the users claim the facilities on Uber car and GPS system of app need to be developed for enhancing the service quality that may further assist the decision making of integrated sustainable transport system.

  • Lane Choice Behavior at Toll Plaza Under Mixed Traffic Conditions Using
           TODIM Method: A Case Study

    • Free pre-print version: Loading...

      Abstract: Abstract The main objective of the present study is to prepare an algorithm for the choice of lane causing minimum delay based on drivers’ perception using a Multi-Criteria Decision-Making (MCDM) method. The TODIM (Portuguese acronym for Interactive Multi-Criteria Decision-Making) is based on the prospect theory. The effect of human behavior on lane choice at toll plaza is studied using the user perception survey. The data required is collected by pictorial survey at the toll plaza, nearby petrol pumps, and hotels. The pictorial survey includes the scenarios to understand the lane choice based on the user preferences about the vehicle composition, number of vehicles in queue, and lane changes. In the case of toll plazas, toll lanes are the alternatives, and vehicle composition of toll lanes, number of vehicles in the queue, and number of lane changes required to choose the target lane are all different criteria. A vehicle entering the toll area has to take care of all the available conditions and select an alternative to minimize the delay. The TODIM method requires the weightage matrix of the criteria, which is obtained using the Analytical Hierarchical Process (AHP). It is seen that the number of vehicles in the queue has the highest weightage followed by the proportion of heavy vehicles. These are the prime factors affecting the lane choice behavior at the toll plaza. The algorithm can be further used to predict the best alternative for the emerging vehicle, which will help to minimize its delay.

  • Examining the Effect of Curb-Side Bus Stop on Time Headway at Multilane
           Divided Urban Roads Under Mixed Traffic Conditions

    • Free pre-print version: Loading...

      Abstract: Abstract Time headway is a microscopic traffic stream parameter used for designing and performance evaluation of a traffic facility. Most of the studies on time headway are limited to homogenous traffic conditions as performed under specific location characteristics. Studies conducted in India, considered entire carriageway width for analysing time headways as the vehicles travel with lack of lane discipline. However, recent macroscopic level studies in India stated that the presence of side-frictions like curb-side bus-stops, on-street parking, encroachments etc., affects the performance of urban arterials. Moreover, side-friction influences the vehicular traffic in the outer most lanes. The present paper demonstrates an investigating study on time headways considering the movement of vehicles on outer and inner lanes with and without the presence of curb-side bus stop on urban roads. Field data for the study are collected at two sections located on a four-lane divided urban arterial in Warangal city. One section is located at curb-side bus stop and another one is located at mid-block of roadway upstream side of the same bus stop section. Field data analysis is performed for entire carriageway as well as for individual lanes by considering 50-50 rule. Statistical parameters are analysed and time headway distributions are fitted at 95% confidence intervals. Capacity of the road sections are calculated from the mean time headways obtained from fitted distributions. The percentage reduction incapacity is found to be 7.92% indicating an interruption to smooth flow of vehicular traffic at curb-side bus stop location. The results obtained by time headway method are compared with INDO-HCM (2017).

  • People’s Preferences for Improvements in Public Transportation Systems:
           An Experience from India

    • Free pre-print version: Loading...

      Abstract: Abstract This paper investigates the potential demand for improved bus service quality in India using the stated preference method. This paper evaluates the effect of passengers’ socio-economic characteristics on their willingness-to-pay (WTP) for improved bus services by focusing on tradeoffs concerning the improvements to passengers’ in-vehicle travel time and comfort level. The paper further compares more preferred improvements among the bus passengers between in-vehicle travel time and comfort level. The paper uses the ordered logit model to analyze decisive factors affecting the opinion of passengers’ WTP for various improvement scenarios. Travel time, fare per trip, family monthly income, motor vehicle ownership, and age are found to be statistically significant to estimate the mean WTP. The results show that users consider the service quality of the public transportation system to be poor and are willing to pay for improved service qualities. As an exciting result, the collected data suggest that passengers are not willing to pay the same level towards improvements in travel time.

  • A Naturalistic Data-Driven Study of Indian Traffic Conditions and
           Driver’s Physiological Stress

    • Free pre-print version: Loading...

      Abstract: Abstract A naturalistic data-driven study was conducted in Chennai, Tamil Nadu, to study drivers’ physiological stress behavior under Indian traffic conditions. Six male participants with professional driving experience were recruited and asked to complete daily trips in urban roadways of Chennai. The participants completed their trips in a sedan-type four-wheeler vehicle mounted with two cameras (near the rearview mirror) to record the traffic data and driver’s in-vehicle behavior. An android phone mounted on the dashboard collected GPS and accelerometer data. The drivers wore an Empatica E4 device to record their physiological data, such as electrodermal activity, a key indicator of physiological stress. A holistic database assembled by linking different kinds of information was used to identify traffic events and road characteristics that can potentially impact the driver’s physiological stress levels. This data was analyzed using a mixed-effects model. It was observed that U-turns and Protected Right turns in an intersection significantly increased the driver’s stress. Additionally, slow-moving traffic in such scenarios further increased the effect. Merge Points serve as undesignated spaces for vehicle and pedestrian crossing and were identified as a contributor to the driver’s stress. Alternatively, the presence of a median and a greater number of lanes significantly decreased the driver’s stress. This paper reports a first-of-its-kind study conducted in India to assess the factors impacting driver’s stress. Adopting measures and initiatives to modify the identified factors can help create a stress-free traffic environment for Indian drivers.

  • Real-Time Delay Estimation Model for Mixed Traffic Conditions Using RFID
           Detections as Data Source

    • Free pre-print version: Loading...

      Abstract: Abstract Queue and delay are the primary performance measures of an intersection. This study aims to determine queue and delay for an approach of a signalized intersection using data obtained from RFID sensors. Model-based estimation schemes were developed for queue estimation that utilized the conservation of vehicles equation as the state equation. Relationships were developed between the time of detection of RFID cars during the red and green phase of a signal cycle and corresponding queue to frame the measurement equation. Real-time estimation of queue was carried out using Kalman filter estimation scheme and delays were estimated from the queue polygons developed. The queue and delay values estimated were comparable with the actual values indicating that the developed method can be used for real-time estimation of queue and delay. The estimation scheme can be used for Advanced Traveller Information Systems (ATIS) for mixed traffic conditions.

  • Understanding the Terminal Area Traffic Flow Characteristics Using Flight
           Record Data

    • Free pre-print version: Loading...

      Abstract: Abstract Terminal area (TMA) is a significant component of the air transportation and air traffic management system. TMA consists of the airport and the transitional airspace between airports and air traffic control sectors and plays a non-trivial role in determining throughput and operational efficiency. Flights in TMA fly through defined courses, distances, and altitudes between specified navigation aids, expressed as standard terminal arrival routes and standard instrument departures. TMA operations are intrinsically complex, and a deeper understanding of TMA operational behaviour and performance is essential to provide timely solutions for schedule and slot allocations, flow, and congestion management. This paper proposes a flight record driven descriptive framework for simplified analysis and characterization of air traffic flows in TMA. This framework aims to perform a cross-sectional descriptive analysis of four key flow performance metrics and proposes a three-step methodology to extract these parameters from flight records. The framework is easy to comprehend, and results can contribute to developing new strategies and decision support tools for TMA traffic management.

      Abstract: Abstract Indian traffic differs significantly from that of developed countries in many aspects, mainly due to its highly mixed nature and weak lane discipline. Capacity of an uncontrolled intersection plays an important role in the overall performance of urban road networks. The non-compliance of the road users to the traffic rules at uncontrolled intersections makes the situation complex. Moreover, roadside frictions like pedestrians interfere with the traffic flow in most of the intersections in India. Gap acceptance method for capacity estimation has few drawbacks in the practical application under the condition of non-compliance behaviour of drivers including influence of pedestrian cross flow. Capacity estimation of intersection with significant pedestrian cross flow can be possible using the conflict method. This paper aims to study the capacity reduction in uncontrolled intersection having significant pedestrian cross flow. For this purpose, traffic video data were collected from two uncontrolled intersections in Kochi City, onewais an ideal site without significant pedestrian cross flow and the other a pedestrian site with significant pedestrian cross flow. The capacity of ideal and pedestrian intersections was estimated using the Highway Capacity Manual (HCM) method as well as conflict method and a comparison was made between them. HCM method gave lesser values of capacity compared to conflict method and also gave unreasonably higher reduction in capacity due to pedestrian cross flow. This proves that HCM methodology is not suitable when the pedestrian traffic is also considered in addition to vehicular traffic in mixed traffic conditions. It was found that the capacity of the pedestrian intersection is 24.8% lesser than the ideal intersection. This study will be helpful for the traffic engineers to suggest a suitable pedestrian facility to reduce the conflicts between vehicles and pedestrians at intersections.

  • Implementation Framework for Bus Queue Jump Lane in Urban Corridors with
           Heterogeneous Traffic Operations

    • Free pre-print version: Loading...

      Abstract: Abstract Queue jump lane (QJL) is a space-optimal facility-based priority measure to improve public transport operation at the intersection where the buses face a majority of the delay. This paper aims to design an implementation framework for QJL by focusing on the geometric specification of QJL and developing design strategy options for different scenarios of implementation. These strategy options have been designed after reviewing the different aspects of QJL, in combination with other elements, such as pre-signal, bus advance area, bus stop location, etc., which can bring effective results in terms of improving the bus travel time without significantly impacting the other vehicle users. After reviewing these strategies, different elements required for the implementation of QJL, such as road geometry, placement, and introduction of signages and road markings, etc., have been identified by studying the planning guidelines of dedicated bus lane/queue jump lanes followed in India as well as other countries. The implementation framework proposed in this work will be useful to practitioners who are interested to implement the queue jump lane as a bus priority measure in India in lieu of the existing practices of only providing dedicated bus lanes.

  • Selection of Sustainable Mode of Transportation Based on Environmental,
           Economic, and Social Factors: Pakistan a Case in Point

    • Free pre-print version: Loading...

      Abstract: Abstract The transport sector has evolved globally with a revolution that has brought innovation and comfort to people's lives. The modern-day commute has become relatively easier and the standard of living has relatively improved. The revolution in the modern era has increased transportation that, on one hand, proves to be good for the general population, but on the other hand, it is resulting in heavy traffic, environmental pollution, and health problems. Furthermore, the utilization of fossil fuels is resulting in resource depletion. A developing country such as Pakistan is currently facing the same situation and thus requires a solution to this problem. To do so, a proper sustainable mode of transportation is deemed necessary, and for this purpose, this research evaluated five different alternatives based on nine distinct criteria. Such a complex decision-making scenario was addressed via a multi-criteria decision-making technique, i.e., Fuzzy-VIKOR. The analysis concluded cycling as the most sustainable mode of transportation for Pakistan. The analysis evaluated cycling to be the most cost-effective and environmentally sustainable alternative for Pakistan’s transport sector, especially for shorter distances. The findings of the study suggest that policymakers must work on implementing cycling dedicated lanes across the country and create awareness by setting examples. The contribution of the study focuses on recommending the government of Pakistan to solve its ever-growing environmental issues by implementing taxes on lavish and non-environment-friendly vehicles. Based on such steps, Pakistan can solve its current issue of smog in different parts of the country and also contribute to better health, and social and economic conditions for its citizens. Furthermore, the implementation of a novel technique proves to be another contribution of the study in the case of such an application.

  • Modeling Modified Intermittent Bus Lane Integrated with Transit Signal
           Priority Under Mixed Traffic Condition

    • Free pre-print version: Loading...

      Abstract: Abstract This study endeavors to develop a new prioritizing scheme for transit vehicles (i.e., bus) without compromising the delay of other traffic by incorporating a modified concept of Intermittent Bus Lane (IBL) with Transit Signal Priority (TSP). Hence, an algorithm was proposed to integrate the scheme with an urban road network having mixed traffic and was simulated in a microsimulation environment. Traffic data of two peak periods, comprising seven (7) hours of traffic flow in each of the three (3) consecutive days, were recorded and extracted using the image processing technique. Moreover, a comparative study was done with commonly practiced priority schemes worldwide for the prevailing traffic conditions in terms of average traffic delay. The results suggested that IBL with TSP outperforms other priority schemes by reducing a minimum of 40-s traffic delay per vehicle than the “Do Nothing” Strategy, in case of lower traffic volume with only 15% of the bus. Besides, a validated “Color Code” was established for the policymakers to choose the best transit priority alternative for the prevailing traffic conditions.

  • Structural and Attitudinal Barriers to Bicycle Ownership and Cycle-Based
           Transport in Gauteng, South Africa

    • Free pre-print version: Loading...

      Abstract: Abstract Policies that aim to facilitate and promote non-motorised transport (NMT), and in particular cycling, have been developed by many high-income countries facing increasingly congested roads and saturated public transport systems. Such policies are also emerging in many low- and middle-income settings where high rates of urbanisation have led to similar problems with motorised transport. The aim of the present study was to better understand the potential structural and attitudinal barriers to cycle-based transport in one such context: South Africa’s Gauteng Province, the industrial powerhouse of sub-Saharan Africa that has recently made a firm commitment to NMT. The study focussed on demographic and socioeconomic variation in bicycle and car ownership, and related this to: (1) the reported use of motorised and non-motorised transport (both private and public); and (2) perceived ‘problems’ with cycling. The analyses drew on interviews with key respondents from n = 27,490 households conducted in 2013 as part of the third Quality of Life survey undertaken by the Gauteng City Regional Observatory. The survey contained items on three outcomes of interest: household vehicle ownership (bicycles and cars); modes of transport used for the “trips” most often made; and respondents’ “single biggest problem with… cycling”. Respondent- and household-level demographic and socioeconomic determinants of these outcomes were examined using descriptive and multivariable statistical analyses, the latter after adjustment for measured potential confounders identified using a theoretical causal path diagram (in the form of a directed acyclic graph). Of the n = 26,469 households providing complete data on all of the variables examined in the present study, only n = 8722 (32.9%) owned a car and fewer still (n = 2244; 8.4%) owned a bicycle. The ownership of these assets was commonest amongst wealthier, economically active households; and those that owned a car had over five times the odds of also owning a bicycle, even after adjustment for potential confounding (OR 5.17; 95% CI 4.58, 5.85). Moreover, of household respondents who reported making ‘trips’ during the preceding month (n = 18,209), over two-thirds of those whose households owned a car (70.1%) reported private car-based transport for such trips, while only 3.2% of those owning a bicycle reported cycling. Amongst the specific responses given to the item requesting the “single biggest problem with… cycling” by far the commonest was “Don’t know how to cycle” (32.2%), less than half as many citing “Vehicle accident risk” (15.9%), and fewer still: “Destination is too far” (13.9%); “Crime” (10.3%); “Too much effort” (9.2%); or “Lack of good paths” (4.6%). While the first of these reasons was commonest amongst poorer households, concerns about risk and effort were both most common amongst better educated, economically active and wealthier/better serviced households. In contrast, concerns over (cycle) paths were only common amongst those owning bicycles. The low prevalence of household bicycle ownership, and the disproportionate number of households owning bicycles that also owned cars, might explain the very small proportion of the ‘the trips most often made’ that involved cycle-based transport (0.3%), and the preferential use of cars amongst households owning both bicycles and cars. Low levels of bicycle ownership might also explain why so many respondents cited “Don’t know how” as the “single biggest problem with… cycling”; although risk and effort were also substantial concerns (presumably for many who did, and some who did not, know how to cycle); the lack of suitable cycle lanes being only primarily a concern for those who actually owned bicycles. Structural and attitudinal barriers to cycle-based transport limit the use of cycle-based transport in Gauteng, not only amongst the vast majority of household respondents who lack the means to cycle (and the means to learn how), but also amongst those dissuaded from learning to cycle, purchasing a bicycle and/or using a bicycle they own by: the risks and effort involved; the lack of suitable cycle paths; and/or because they also own a car and prefer to drive than cycle.
