  • 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.

  • Capacity Analysis of Uncontrolled Intersections with and Without
           Pedestrian Cross Flow in Mixed Traffic Conditions

    • Free pre-print version: Loading...

      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.

  • Public Transport Passenger Attraction Using Policy Interventions for a
           Post-COVID Scenario

    • Free pre-print version: Loading...

      Abstract: Abstract Public transport (PT) ridership has seen a continual decline over the past years as more people are opting to use private vehicles, contributing to increased traffic congestions, road accidents, pollution, etc. The COVID-19 pandemic has exacerbated this problem, with official guidelines discouraging the use of PT systems to prevent contagion. Passenger attraction policies for a post-pandemic phase should be formulated by examining the changes in daily trips brought about by the COVID-induced lockdowns. With data collected from employees working in Thiruvananthapuram city, the present study develops a post-lockdown mode-choice model using fuzzy logic programming to evaluate different policies to increase PT ridership. The policies such as introducing parking prohibition on major streets, reducing return-trip fares, improving PT coverage and supply, and early-bird pre-peak hour discounts were tested using sensitivity analysis and the choice model estimated a (private to PT) modal shift of 5.8%, 6.9%, 6.2% and 6.2%, respectively. It is concluded that passenger attraction policies should concentrate more on improving PT services than discouraging private modes to improve ridership.

  • A Fuzzy Analytic Hierarchy Process and VIKOR Framework for Evaluation and
           Selection of Electric Vehicle Charging Technology for India

    • Free pre-print version: Loading...

      Abstract: Abstract The climatic and environmental issues, rapid urbanisation, and technological developments in renewable energy in recent years have led to the rise of electric vehicles (EVs) for sustainable transportation. In the last decade or so, a set of situations have formed a way for electric mobility to enter India’s primary market, but it is still in its initial phase. Charging infrastructure can be considered a supporting pillar of this EV promotion scheme. The serviceability of a charging station is greatly affected by its location and the technology available. Hence, to fully incorporate EVs in the transportation sector, their charging technologies and stationing at appropriate charging sites must be analysed thoroughly. The selection of electric vehicle charging technology is a complex procedure. It can be decomposed into a decision-making problem with various criteria and alternatives to be considered simultaneously. This can be done using a multi-criteria decision-making (MCDM) technique. This study provides a fuzzy analytic hierarchy process (Fuzzy-AHP) framework to evaluate different criteria affecting our alternate technologies. Further, another MCDM Technique, VIKOR, is used to find solutions closest to the ideal condition and rank the alternate technologies. However, the selection of technology may vary from place to place. This study evaluates the criteria based on experts’ opinions. It is observed that the criteria reliability has the least weight, and charging time holds the maximum weight. This study favours battery swapping among all the available alternatives.

  • A View of Commercial Motorcycle Transportation in Sub-Saharan African
           Cities Through the Sustainable Development Lens

    • Free pre-print version: Loading...

      Abstract: Abstract The mobility challenges in sub-Saharan Africa (SSA) have given rise to commercial motorcycle transportation. Nonetheless, its regularisation remains a fierce contest between two categories of stakeholders: critics and protagonists. While the critics base their arguments on the safety and crime concerns associated with it, the protagonists argue based on its support for livelihoods. However, none of these arguments are grounded in the region’s quest for sustainable development. Using the sustainable development prism as an analytical framework, this study unpacks the effects of commercial motorcycle transportation on the region’s sustainable development efforts for evidence-based decision-making. The results of the study are based on a systematic review of literature from reputable academic databases. A synthesis of the literature reveals that commercial motorcycle transportation profoundly impacts SSA’s economic and social sustainability efforts. The roles include livelihood support, revenue to governments and mobility enhancement. Nevertheless, it is associated with health and safety, security and pollution concerns. Based on these and the entrenched mobility difficulties in SSA, the authors conclude that abolishing commercial motorcycle transportation may amount to ‘throwing away the baby with the bathwater’. Instead, the principle of hazard analysis and critical control point could be a valuable concept to developing risk management strategy for commercial motorcycle transportation.

  • Durability Performance of Cementitious Mixes with Reclaimed Asphalt
           Pavement Aggregates

    • Free pre-print version: Loading...

      Abstract: Abstract The effect of fine fraction of Reclaimed Asphalt Pavement (RAP) aggregates on durability characteristics of mortar and concrete were assessed. The natural fine aggregates were replaced by finer fraction of RAP at 25%, 50%, 75% and 100% by volume. Resistance to sulfate and acid attack, drying shrinkage, alkalinity, chloride content and presence of carbonation of the mixes were analyzed. Increase or equivalent strength was observed for both mortar and concrete specimens with 50% or lower RAP replacement level under sulfate attack in sodium sulfate solution in comparison to decrease in strength under sulfate attack in sulfuric acid and acid attack in hydrochloric acid solutions. This is due to difference in formation and filling of pores and microcracks by salt—crystallization products in mortar and concrete. The pore distribution characteristics such as threshold diameter supports this observation as well. The threshold diameter decreases from control mix to 50% RAP mix and then increases. Similar pattern of observation was seen in concrete mixes as well. The drying shrinkage of RAP inclusive cementitious mixes were within the stipulated limits. The RAP inclusive concrete mixes do not pose any threat to the reinforcement due to absence of carbonation, chloride content being lower than the maximum limits and pH content between 12 and 13. From the study, it may be concluded that fine RAP inclusive cementitious mixes have durability life and has the potential to be used as pavement quality concrete.

  • Reduction in Idling Fuel Losses and Corresponding Emissions Due to
           Awareness Campaign at the Signalized Intersections in Delhi

    • Free pre-print version: Loading...

      Abstract: Abstract With increasing traffic at intersections, it becomes essential to install traffic control devices to regulate the movements. These controlled intersections are known as “Signalized Intersections”. When the vehicles are waiting for their turn to clear the signalized intersection, the drivers normally do not keep the engines off and this results in extra fuel consumption due to idling and increased vehicular emissions. This fuel consumption can be saved along with reduction in corresponding emissions by switching off vehicle engine during idling at signals. In the present study, a 40 day-long awareness campaign has been carried out at 100 signalized intersections in Delhi to create awareness among drivers regarding switching off their engines during idling. Impact of awareness campaign has been estimated based on number of vehicles switching-off their engines during idling which is further used to estimate idling fuel losses and corresponding emissions. The observed proportion of switched-off Two-wheelers before, during, and after phase of awareness campaign was ~ 18%, ~ 51%, and ~ 44%, respectively. Similar trend has also been observed for Three-Wheeler users. There was ~ 22% reduction in idling fuel losses for petrol fuel between “before” and “after” campaign phase. Similarly, ~ 14%, 12%, and 19% reduction in Diesel, CNG, and LPG idling fuel losses was observed due to awareness campaign. Furthermore, it was estimated that 9357 CO2eq (CO2 equivalent) t/d of GHG emission was generated at selected 100 signalized traffic intersections “before” the start of the awareness campaign. This was reduced to 7976 t/day (~ 1381 CO2eq t/day or ~ 14% reduction) in “after” phase of the awareness campaign.

      Abstract: Abstract Researchers are constantly seeking for a quick, inexpensive, and easy-to-use way to mitigate the severity of road accidents. This study proposes the use of a simulator driver model, i.e., a dynamic vehicle model presented in a fractional factorial experiment for the identification of active factors in road accidents. The investigation was based on an accident database of a real two-lane highway that composed the scenario simulation, and tests were conducted in a 10-km path with 39 tangent-curve configurations. Seven factors, namely curve radius, path profile, path condition, virtual driver skill, speed, period of the day, and carload were considered and three replicates were performed per treatment. Speed and friction coefficient were randomly defined for each treatment within the range established for each level. The first experimental design was a quarter fraction, and 42 accidents were observed in 96 events. Speed exerted the highest influence on their occurrence, followed by curve radius, period of the day, and some second-order interactions. The second part of the experimental design was based on the results of the first. A half fraction factorial design with five factors and 14 replicates per treatment were performed, and 96 accidents were observed in 224 events. Speed exerted the highest influence on their occurrence, followed by period of the day, curve radius, virtual driver skill, and second-order interactions. The study has contributed to the understanding of the way drivers drive vehicles on a road with a small S-curve and to assessment procedures for analyses of risk factors and improvements in road safety.

  • Estimating the Effects of Light Rail Transit (LRT) on Land Price in
           Kaohsiung Using Geographically Weighted Regression

    • Free pre-print version: Loading...

      Abstract: Abstract Mass Rapid Transit (MRT) can greatly improve the accessibility of the area and bring capitalization benefits to the surrounding land value. Due to financial budget constraints, the government often uses Land Value Capture for investment and financing. However, the research on the spatial variations in the influence of MRT on land value improvement at different stages is relatively rare. Therefore, in this paper, the spatial interpolation of Inverse Distance Weighted (IDW) in GIS spatial analysis and the hedonic price model based on ordinary least square (OLS) are used to establish a model based on Geographically Weighted Regression, so as to explore the impact of LRT on residential and commercial land prices along the LRT line from time and space dimensions. The results are: (I) there are significant spatial variations in the influence of Kaohsiung LRT on the land prices along the line at different stages. During the announcement period, the residential land prices will increase by an average of 0.08% for every 1% of the distance near the LRT station within 400 m of the line. In the construction period, the effect of LRT on residential and commercial land prices is basically the same. In the operation period, LRT only has a significant negative impact on residential land prices of the area from the Kaohsiung Exhibition Hall Station (C8) to Hamaxing Station (C14). (II) The GWR models have better local estimation effect than the global regression OLS models, and can better reflect the complex spatial changes.

  • Effect of Social Groups on Crowd Movement in Mass Religious Gatherings: A
           Case Study of Kumbh Mela

    • Free pre-print version: Loading...

      Abstract: Abstract In mass religious gatherings like Kumbh Mela, where participation of groups is much higher than individuals, studying the impact of groups on the macroscopic parameters is imperative. Although many researchers have studied group behaviour and its dynamics, the effect of the presence of groups in different group sizes on crowd movement is seldom studied. This paper tries to strengthen the existing literature by studying the impact of the presence of groups and group sizes on crowd movement in two major attractions of Kumbh Mela-2016. The average speed was found to decrease as the group size increased. Further, while comparing the groups’ speeds with isolated pedestrian speeds, it was inferred that the presence of groups slows overall crowd movement. This is done assuming a location as an isolated pedestrian section, based on a few criteria. This study will help bring out interesting insights on the effect of groups in the crowd and uncover their impact on the overall speed of the crowd. This study can also help the event planners and managers to take proper crowd management measures (such as appropriate barricading, streamlining the flow, etc.) whenever there is a reduction in speeds at the ghat or temple regions.

  • Socio-economic and Trip Characteristics Influencing the Travel Time
           Perception of Cyclists: A Case Study of a Residential Academic Campus

    • Free pre-print version: Loading...

      Abstract: Abstract The perceived travel time is one of the important trip characteristics used in the field of travel behavior research. This study analyses the socio-economic and the trip characteristics influencing the travel time perception of the cyclists in a residential academic campus. Two approaches were used to gather the relevant information from the daily commuting cyclists. First, the actual travel time was collected by manually noting down the starting and ending times of the trip as well as using the smartphone sensors. Second, a questionnaire survey was administered to obtain the perceived travel time, other travel parameters, socio-economic, and behavioral characteristics of the trip maker. Using the actual and the revealed data, the present study has evaluated the perception error ratio (PER) and the difference in the perceived and actual travel times, and classified the over and under perceived trip makers. Then the factors influencing the perception error of cyclists were identified. Model results revealed that the use of PER misclassifies the over and under perceived trip makers. Actual travel time and the income level were found to influence the perception error corresponding to both the under and over perceptions. It was also found that the activities of the trip maker, during the trip have a significant influence on the trip makers’ perception.

  • Measuring and Modelling Electric Vehicle Adoption of Indian Consumers

    • Free pre-print version: Loading...

      Abstract: Abstract Advancements in energy-efficient sustainable mobility technologies like electric vehicles are considered as one of the essential responses to minimizing the greenhouse gas emissions from the transportation sector. In spite of financial and non-financial incentives being provided to both consumers and manufacturers in India, the acceptance and adoption of electric vehicles remains very low. Based on the extended unified theory of acceptance and use of technology (UTAUT) model, this study uses structural equation modelling to analyze the effects of eight factors viz. environmental enthusiasm, technological enthusiasm, anxiety (or perceived risk), social image, social influence, perceived benefits, performance expectancy and facilitating conditions on the consumers’ intention to adopt electric vehicles. The study is analytically examined based on the data obtained from 675 students in Bengaluru, India. Results indicate that environmental enthusiasm, technological enthusiasm, social image, social influence, perceived benefits, and performance expectancy are positively related to adoption intention whereas facilitating conditions and anxiety have negative influence on a consumer’s intention to adopt an electric vehicle. This study adds to the limited literature on this subject in the context of developing economies. In practice, the results from this study can be useful to planners and policy makers to improve the adoption rate of electric vehicles.

  • Commuters' Willingness-to-Pay for the Attributes of Plug-in Hybrid
           Electric Vehicle: A Case Study in Kolkata, India

    • Free pre-print version: Loading...

      Abstract: Abstract The present study investigates commuters’ willingness-to-pay (WTP) for the attributes of plug-in hybrid electric vehicle (PHEV) in a typical Indian context. A stated preference discrete choice experiment was designed to collect choice responses from potential users of PHEV in Kolkata, India. The collected data were analyzed by developing multinomial logit (MNL) and mixed logit (ML) models to estimate overall commuters’ WTP for a set of key attributes of PHEV namely purchase price, fuel cost reduction, battery range, public charging station, battery recharging time, battery warranty and tailpipe emission. Additionally, in ML model, heterogeneity around the mean of random parameters with respect to sociodemographic characteristics such as age, monthly family income, car ownership, home-based parking facility and education, and trip characteristics such as average commuting trip length were examined, and WTP estimates were evaluated for different population sub-groups. The model estimation results indicate that ML models are overall statistically superior and represent the data better than MNL model. The results also highlight that the high purchase price of PHEV as compared to conventional vehicle (CV) could be one of the major deterrents towards the purchase of PHEV in Indian context. The WTP estimates indicate that commuters perceive battery warranty as the major determinant influencing the choice of PHEV followed by battery recharging time and tailpipe emission. The potential users’ income, availability of home-based parking facility, education, and average commuting trip length also substantially influenced their WTP for several attributes of PHEV in Indian context.
