  • Abstracting mobility flows from bike-sharing systems

    • Free pre-print version: Loading...

      Abstract: Bicycling has grown significantly in the past ten years. In some regions, the implementation of large-scale bike-sharing systems and improved cycling infrastructure are two of the factors enabling this growth. An increase in non-motorized modes of transportation makes our cities more human, decreases pollution, traffic, and improves quality of life. In many cities around the world, urban planners and policymakers are looking at cycling as a sustainable way of improving urban mobility. Although bike-sharing systems generate abundant data about their users’ travel habits, most cities still rely on traditional tools and methods for planning and policy-making. Recent technological advances enable the collection and analysis of large amounts of data about urban mobility, which can serve as a solid basis for evidence-based policy-making. In this paper, we introduce a novel analytical method that can be used to process millions of bike-sharing trips and analyze bike-sharing mobility, abstracting relevant mobility flows across specific urban areas. Backed by a visualization platform, this method provides a comprehensive set of analytical tools to support public authorities in making data-driven policy and planning decisions. This paper illustrates the use of the method with a case study of the Greater Boston bike-sharing system and, as a result, presents new findings about that particular system. Finally, an assessment with expert users showed that this method and tool were considered very useful, relatively easy to use and that they intend to adopt the tool in the near future.

  • Pedestrian safety at intersections near light rail transit stations

    • Free pre-print version: Loading...

      Abstract: Abstract The focus of this paper is two-fold—(1) to research and identify critical predictor variables such as road network and land-use characteristics that influence pedestrian safety at intersections near light rail transit (LRT) stations, and, (2) to examine the change in pedestrian crash patterns at these intersections before and after the LRT is in operation to serve the users. Pedestrian crashes, road network, and land-use characteristics within a vicinity of 0.25 miles (402 m) at 70 selected intersections near fifteen LRT stations in Charlotte, North Carolina were considered in this research. The predictor variables were examined to minimize multicollinearity and develop four different non-linear regression models. The findings from the three best models indicate that the number of bus stops, mixed use area, office area, single-family residential area, industrial area, and the presence of a railroad flasher have a statistically significant influence on the number of pedestrian crashes at an intersection near an LRT station. An increase in the total number of pedestrian crashes at the selected intersections near LRT stations was observed during the after-period compared to the before-period. The increase in the number of pedestrian crashes varied with the pedestrian crash history of the intersection.

  • Effects of rural bus stops on travel time and reliability

    • Free pre-print version: Loading...

      Abstract: Abstract Due to relatively low patronage levels, rural bus stops are sometimes questioned in order to improve travel time and reliability on regional bus services. Previous research into stop spacing has focused on urban areas, which means that there is a lack of knowledge regarding the effects of bus stops in regional networks, with longer distances, higher speeds, and lower passenger volumes, in general. The present study addresses this knowledge gap by analysing the effects of bus stops on a regional bus service regarding average travel times, travel time variability, and on-time performance. This is done by statistical analysis of automatic vehicle location (AVL) data, using a combination of methods previously used for analysis of rail traffic and urban bus operations. The results reveal that bus stops that are only used sporadically have a limited impact on average travel times, in general. In contrast, they are all the more influential on travel time variability, and, in turn, on on-time performance. On the studied bus service, the number of stops made have a far greater impact on travel time variability than any of the other included variables, such as the weather or traffic conditions during peak hours. However, the results suggest that rural bus stops have a much lower impact than what we define as secondary bus stops in urban areas. Consequently, by primarily focusing on bus stop consolidation in urban areas, it is possible to significantly improve service reliability without impairing rural coverage.

  • A column generation approach for the driver scheduling problem with staff
           cars

    • Free pre-print version: Loading...

      Abstract: Abstract Given a set of timetabled bus trips, transport companies are faced with the challenge of finding a feasible driver schedule that covers all trips and abides by various labor union regulations. The regulations are primarily concerned with providing sufficient breaks for the drivers during the day. Practical limitations in the city network enforce drivers to travel by cars between bus stops to have breaks. Transport companies have a limited number of cars, known as staff cars, which have to be returned to their respective depots at the end of the day. The simultaneous scheduling of drivers and staff cars for the drivers is known as the driver scheduling problem with staff cars (DSPSC). It is estimated that the DSPSC accounts for 60% of a bus company’s operational expense, and this paper proposes a column generation approach that attempts to minimize operational expense. The column-generation framework iterates between a master problem, a subproblem for generating driver variables and a subproblem for generating staff car variables. The subproblem related to the drivers is formulated as a resource constrained shortest path problem, which is solved by a dynamic programming approach. Several heuristic branching strategies are explored to find integer solutions. The proposed methodology is tested on eight real-life instances from seven Northern European bus companies. A comparison with a state-of-the-art mixed integer programming (MIP) solver and an adaptive large neighborhood search (ALNS) heuristic indicate that the column generation approach provides improved solutions for six instances and the average improvement is 1.45%.

  • The psychophysiological status of rail traffic operators and modern
           approaches to its correction

    • Free pre-print version: Loading...

      Abstract: Abstract In order to reduce the risk and assess the organism’s ability to cope with stress in the changing workplace environment of the rail industry, we have conducted psychophysiological examinations to assess the functional status of 204 rail transport operators (Astana, Kazakhstan). The occupational composition included traffic operators, in particular, train, terminal, locomotive, and energy operators, 204 persons in total. The assessment included the analysis of professional activity, registration of 22 characteristics of labor stressfulness across three subdivisions and sections, and psychophysiological status tests over the course of a shift using EPDK-MK and Varicard automatic machines. Functional studies were conducted via certified methods before and after the shift. The reliability of traffic operators depends on their health, since any deviations can affect the mental processes that are responsible for professional activity. It was found that the indicators of the psychophysiological status were characterized by pronounced fatigue, which required not only pre-shift control, but also post-shift express correction. Recommendations how to reduce stress were marked. The main ones are improvement of equipment, giving on the job access to professional psychological counseling, support during work in dangerous conditions and modeling of an optimal daily routine.

  • Modelling second-best choices from the choice-based sample: revelation of
           potential mode-switching behaviour from transit passenger surveys

    • Free pre-print version: Loading...

      Abstract: Abstract The paper presents an application of the choice-based sample to explain the choice of non-chosen alternatives. It uses a passenger survey of GO rail transit of the Greater Toronto and Hamilton Area to investigate the factors that may affect the potential mode switching of the current GO rail users. It used a hybrid generalized extreme value with an endogenous latent variables model for jointly modelling the GO rail station access mode choice and the choice of switching from GO rail to alternative modes. The empirical results reveal that the influence of station access difficulty does not become an issue for relatively shorter access distance (e.g. station access distance is less than 5% of the total origin–destination distance). The traveller would rather switch access mode than switching away from GO rail for such a case. Competition of alternative modes, captured through the composite cost of using an alternative to GO rail, is also found to be critical in potential switching from GO rail. It is also clear that drive-alone is the most attractive alternative to switch to. Overall, the empirical investigations reveal that land-use policies that encourage higher residential density around a GO rail station would make a higher number of modes (including non-motorized modes) feasible as access to GO rail mode and thereby reduce the impact of access cost on mode switching behaviour from GO rail. Similarly, developing a high occupancy vehicle lane network and high occupancy tolled road network to serve along the corridors that are served by GO rail would encourage multimodality and help to tackle GO rail’s capacity constraints and their corresponding negative effect of in-train crowding.

  • Zero bunching solution for a local public transport system with
           multiple-origins bus operation

    • Free pre-print version: Loading...

      Abstract: Abstract Bus bunching in public transport is the concentration of similar buses having different schedules to a common time point. The reason for this phenomenon is variations existing in the bus operation as earliness and lateness. Bus bunching has the consequence of reduced service reliability concerning both passengers and operators. A zero bunching state is vital for enhancing the usage of public transport where the buses operate with utmost schedule adherence. Two generally adopted strategies for solving bus bunching are a schedule-based strategy which provides slack time in a timetable to address late running and fixed departure time for the early operations, and a headway-based strategy that maintains headway between buses. Bus bunching due to multiple origins is a special case in which common tactics cannot effectively control a bunching tendency that arises at the entry point. The operation schedules of multiple origins must be so designed that a state of zero bus bunching can be ensured while buses from different origins reach the entry points. This article presents a model of a multiple-origins public transport network as a combination of origins, routes and entry points, developed in the search for achieving a zero bunching state in the operation beyond an entry point. The origins are modelled based on the entry-point variables. The routes are modelled based on the running time, departure time, arrival time, and dwell time. The entry points are modelled based on route and entry-point variables. Redesigning route schedules based on the entry-point characteristics and an appropriate slack time implementation are proposed and observed to be suitable for overcoming bunching in a multiple-origins bus operation.

  • Mode boundaries of automated metro and semi-rapid rail in urban transit

    • Free pre-print version: Loading...

      Abstract: Abstract Our research question is to what extent, and under what circumstances, full automation in metro lines defines transit mode boundaries with respect to semi-rapid transit. The modeling approach is based on micro-economic appraisal. Automation, beside changing the investment and operation and maintenance cost profiles of metro lines, can improve some aspects of the user experience. The low marginal cost of frequency possible with automated metro may unlock both users’ benefits via reduced waiting times and crowding, and operator’s savings via shorter trains and smaller platforms and stations. We show how the user’s travel time components are structurally different under several configurations. In particular, we highlight the critical role that different demand and alignment patterns play in the mode comparison.

  • Optimal design of a bus route with short-turn services

    • Free pre-print version: Loading...

      Abstract: Abstract In today’s world, the transit load of urban areas has increased tremendously, so the costs related to the operations has increased and ensuring a certain level of service has become challenging. Bus service is one of the most widely used modes of public transportation. A critical issue of bus services is to manage the limited capacity of buses efficiently. To cope with the limited capacity efficiently, short-turn service patterns are commonly used as a bus route design strategy. In this study, we propose a modelling approach to design a bus route with short-turn service patterns accounting for various objectives of the operator and passengers, such as minimizing the capacity surplus, capacity shortage and passenger time related costs. We present a real-life case study showing the significant benefits of short-turn services. The results show that the pareto-frontier curves are similar for different time periods (i.e. low- and high-demand periods). Most importantly, the trade-off between capacity surplus and shortage is not linear in case of a short-turn service strategy. Significant gains can be achieved in capacity shortage by decrementing the capacity surplus slightly. Additionally, capacity shortage can be improved much easier compared to passenger time costs when a short-turn service pattern strategy is used. We also show that using optimal route design with a short-turn strategy yields a capacity surplus improvement of 60–70% in return for only 1% decrement of capacity shortage compared to the current practice without short-turns in a case study.

  • Optimal balanced chain decomposition of partially ordered sets with
           applications to operating cost minimization in aircraft routing problems

    • Free pre-print version: Loading...

      Abstract: Abstract We consider the task of constructing a cost-effective daily flight schedule with a minimum number of required aircrafts and a maximum number of balanced flight routes, namely, routes with the same start and end spatial location. We suggest a solution strategy which is able to determine the problem’s hardness by estimating the number of all flight plans with a minimum number of required aircrafts. Provided that this number is not too large, the same algorithm is utilized for fully enumerating and detecting the set of solutions that have the maximum number of balanced routes. Our experimental study implies that the method is both effective and scalable in practice. For example, when applied to the Australian domestic flights timetable which is serviced by a total of eighty-eight aircrafts, our method manages to increase the number of balanced flight routes from nine to forty-two, while using only several minutes of computational time.

  • Estimating the demand for informal public transport: evidence from
           Antananarivo, Madagascar

    • Free pre-print version: Loading...

      Abstract: Abstract Informal public transport has been growing rapidly in many developing countries. Because urban infrastructure development tends to lag behind rapid population growth, informal public transport often meets the growing gap between demand and supply in urban mobility. Despite the rich literature primarily focused on formal transport modes, the informal transport sector is relatively unknown. The paper analyzes the demand behavior in the “informal” minibus sector in Antananarivo, Madagascar, taking advantage of a recent user survey of thousands of people. It is found that the demand for informal public transport is generally inelastic. Essentially, people have no other choice but to use this kind of public transport. While the time elasticity is estimated at − 0.02 to − 0.05, the price elasticity is − 0.05 to − 0.06 for short-distance travelers, who may have alternative choices, such as motorcycle taxi or walking. Unlike formal public transportation, the demand also increases with income. Regardless of the income level, everyone uses minibuses. The estimated demand functions indicate that people prefer safety and more flexibility in transit. The paper shows that combining these improvements and fare adjustments, the informal transport sector can contribute to increasing people’s mobility and reducing traffic congestion in the city.

  • Life cycle environmental impact of a high-speed rail system in the
           Houston-Dallas I-45 corridor

    • Free pre-print version: Loading...

      Abstract: Abstract The Houston-Dallas (I-45) corridor is the busiest route among 18 traffic corridors in Texas, USA. The expected population growth and the surge in passenger mobility may result in a significant impact on the regional environment. This study uses a life cycle framework to predict and evaluate the net changes of environmental impact associated with the potential development of a high-speed rail (HSR) System along the I-45 corridor through its life cycle. The environmental impact is estimated in terms of CO2 and greenhouse gas (GHG) emissions per vehicle/passenger-kilometers traveled (V/PKT) using life cycle assessment. The analyses are performed referring to the Ecoinvent 3.4 inventory database through the phases: material extraction and processing, infrastructure construction, vehicle manufacturing, system operation, and end of life. The environmental benefit is evaluated by comparing the potential development of the HSR system with those of the existing transportation systems. The vehicle component, especially operation and maintenance of vehicles, is the primary contributor to the total global warming potential with about 93% of the life cycle GHG emissions. For the infrastructure component, 56.76% of GHG emissions result from the material extraction and processing phase (23.75 kgCO2eq/VKT). Various life cycle emissions of HSR except PM are significantly lower than for passenger cars.

  • Public transportation vehicle selection by the grey relational analysis
           method

    • Free pre-print version: Loading...

      Abstract: Abstract The success of businesses today is largely dependent on their ability to find solutions to complex problems they encounter. Vehicle selection, which requires considering many objective and subjective criteria, is at the top of these problems. The tramway selection problem of a company operating in the public transport sector in Turkey is discussed in this study. The company wants to increase passenger carrying capacity and renew its vehicle fleet. For this purpose, it has to choose from eight alternative vehicles with different superior features. Considering the high costs that may arise from wrong selection, it becomes clear how important it is to use the right method to solve the problem. In this study, the evaluation criteria were determined by taking the opinions of experts first. Then, weights were assigned to the criteria using the Analytical Hierarchy Process (AHP). In the last stage, the best alternative has been tried to be determined by using grey relationship analysis (GRA). It is common to use more than one method to test the reliability of the results in solving multi-criteria decision-making (MCDM) problems. In this study, multi-objective optimization, based on ratio analysis (MOORA), which is one of the most preferred methods to solve MCDM problems, was used to test the accuracy of the results. Although various MCDM methods are used in the literature to solve similar problems, the use of grey relationship analysis has not been encountered. With this aspect, this study has expanded the application of grey theory and made an important contribution to the literature. Another important contribution of the study is that the evaluation criteria for the tramway selection problem have been determined with the help of experts. Finally, this study presents a scientific approach to the solution of a complex real-life problem.

  • Effects of system configurations of automated fare collection on transit
           

    • Free pre-print version: Loading...

      Abstract: Abstract Automated fare collection (AFC) systems such as smart cards are becoming increasingly popular among transit agencies worldwide. Two main configurations of AFC systems can be found, characterized by whether users are required to scan their cards at the beginning of their trips (i.e., entry-only system) or both at the beginning and end of their trips (i.e., entry–exit system). Recently, there has been growing interest in implementing the latter configuration in order to provide more equitable fare structures that charge users based on distance, while arguably providing more accurate data for an origin-destination analysis of users. Therefore, this study explores the spatial and temporal differences in transit users’ origin-destination estimations that are based on the two AFC system configurations. To achieve this goal, it uses AFC system data collected from GO Transit, the operator of the regional commuter rail and bus systems in the Greater Toronto and Hamilton Area (GTHA). A comprehensive model was developed which suggests that the entry–exit AFC system configuration helps in estimating about 14% more trips than an entry-only AFC system configuration; the latter uses a set of common assumptions that are normally employed by researchers in estimating users’ destinations. Spatial, temporal and mode related differences between the two system estimations were also found. This paper offers policy makers and planners a better understanding of the possible benefits/impacts of implementing entry–exit systems vs. entry-only systems on transit users’ origin-destination estimations.

  • Optimizing bus line platform assignment across bus stations in Utrecht

    • Free pre-print version: Loading...

      Abstract: Abstract Due to its increased popularity, public transport has grown considerably, which has resulted in more lines that are operated with higher frequencies. As a result, the current bus stations that are located in strategic places like city centers to serve as a hub are becoming too small. If there is no space to enlarge the station, then usually the best option is to create a second bus station close-by. This raises the problem of distributing the bus lines over the bus stations, such that good connections are offered to transfer passengers. We have considered this problem in the city of Utrecht, which is a middle-sized city in the center of the Netherlands. The central transit hub, which is located next to the central railway station, consists of several separate bus stations. The goal of the research is to minimize the total travel time for all passengers who want to transfer at the hub. Here we are not allowed to adjust the current timetable, and we have to take the capacity and vehicle limitations into account. To find out which journeys are made daily and by how many people we use data from a digital fare system. This results in passenger groups, and for each group we compute the relevant travel options given the current timetable. Thereto, the routes are split into an inbound itinerary, a transfer within the same bus station, and an outbound itinerary; the validity of a travel option depends on the assignment of the bus lines to the bus stations. We decompose the problem into first finding a distribution of the lines over the stations and then assigning them to a platform at the station of choice. In the first subproblem, we find the best set of transfers using Integer Linear Programming (ILP), resulting in a station assignment. In the second subproblem, for each station, we distribute the bus lines over the platforms. In this subproblem, there can be multiple lines assigned to a single platform, as long as there are never more vehicles at the platform simultaneously than physically fit. The goal is to maximize the comfort of the transfer passengers by assigning tight transfers to adjacent platforms; this problem is solved using ILP as well.

      Abstract: Abstract Bus rapid transit (BRT), as a modern mode of transportation, plays an increasingly important role in urban public transport. A real-time vehicle positioning and passenger flow sensing system is developed to collect and process the high-frequency data of the BRT operation status and passenger flow at BRT stations. Based on the established spatial analysis model, the intersection delay, running state, passenger flow and stranded passengers of BRT are analyzed. The experiment showed the outcome had a high accuracy and strong reference. It provided the transit agency with a timely, detailed and accurate decision-making basis to grasp the true operation situation of the BRT and carry out each BRT scheduling task scientifically, so as to improve the management efficiency and service level of BRT.

  • Understanding the temporal and spatial interactions between transit
           ridership and urban land-use patterns: an exploratory study

    • Free pre-print version: Loading...

      Abstract: Abstract The land-use characteristics of urban areas continually change, and thus the activity patterns of the significant trip generators evolve. Efficient public transit planning needs to perform frequent estimates of the spatio-temporal distribution and dynamics of different activities in urban areas and measure the likely consequences of changes. Automated data collection systems usually collect transit ridership data (e.g., automated passenger count (APC)). Many transit agencies also generate General Transit Feed Specification (GTFS) data and make them publicly available. This study explores the use of APC, GTFS, and land-use data to examine various land-use and transit ridership interactions at the stop, route, and zonal levels using visualization, data mining, and statistical analysis techniques. Results show that transit ridership at the bus stop level gives a better understanding of each bus stop's unique land use. Zonal-level transit ridership patterns reveal the different trip generations and attraction roles of the neighboring land usage. This study could provide additional insights on the interaction between the temporal changes in population from the perspective of transit use and the associated land uses.

  • Analyzing public transport in the city of Buenos Aires with MobilityDB

    • Free pre-print version: Loading...

      Abstract: Abstract The General Transit Feed Specification (GTFS) is a data format widely used to share data about public transportation schedules and associated geographic information. GTFS comes in two versions: GTFS Static describing the planned itineraries and GTFS Realtime describing the actual ones. MobilityDB is a novel and free open-source moving object database, developed as a PostgreSQL and PostGIS extension, that adds spatial and temporal data types along with a large number of functions, that facilitate the analysis of mobility data. Loading GTFS data into MobilityDB is a quite complex task that, nevertheless, must be done in an ad-hoc fashion. This work describes how MobilityDB is used to analyze public transport mobility in the city of Buenos Aires, using both, static and real-time GTFS data for the Buenos Aires public transportation system. Visualizations are also produced to enhance the analysis. To the authors’ knowledge, this is the first attempt to analyze GTFS data with a moving object database.

  • Measurement and classification of transit delays using GTFS-RT data

    • Free pre-print version: Loading...

      Abstract: Abstract This paper presents a method for extracting transit performance metrics from a General Transit Feed Specification’s Real-Time (GTFS-RT) component and aggregating them to roadway segments. A framework is then used to analyze this data in terms of consistent, predictable delays (systematic delays) and random variation on a segment-by-segment basis (stochastic delays). All methods and datasets used are generalizable to transit systems which report vehicle locations in terms of GTFS-RT parameters. This provides a network-wide screening tool that can be used to determine locations where reactive treatments (e.g., schedule padding) or proactive infrastructural changes (e.g., bus-only lanes, transit signal priority) may be effective at improving efficiency and reliability. To demonstrate this framework, a case study is performed regarding one year of GTFS-RT data retrieved from the King County Metro bus network in Seattle, Washington. Stochastic and systematic delays were calculated and assigned to segments in the network, providing insight to spatial trends in reliability and efficiency. Findings for the study network suggest that high-pace segments create an opportunity for large, stochastic speedups, while the network as a whole may carry excessive schedule padding. In addition to the static analysis discussed in this paper, an online interactive visualization tool was developed to display ongoing performance measures in the case study region. All code is open-source to encourage additional generalizable work on the GTFS-RT standard.

  • The influence of vicinity to stations, station characteristics and
           perceived safety on public transport mode choice: a case study from
           Copenhagen

    • Free pre-print version: Loading...

      Abstract: Abstract The perception of safety within the public transport system is of high importance for passengers according to multiple passenger satisfaction surveys. However, among the many studies of public transport mode choice, little focus has been on the influence of safety perceptions. This study contributes to existing literature by specifically investigating the influence of perceived safety on public transport mode choice using a large-scale multimodal travel survey with 17,355 respondents and 42,438 trips from the Greater Copenhagen area. This made it possible to analyse safety at stations while still taking into account other main determinants of public transport usage. The study also includes walking distances to various public transport stops, e.g. metro, suburban and regional train stations, and bus stops, hence taking into account possible differences in attitudes towards different public transport modes. The results of a logistic regression confirm the hypothesis of lower perceived safety at stations being negatively correlated with public transport mode choice, but still to a smaller extent than that of service characteristics in terms of service frequency. The study also revealed that travellers perceive metro and suburban rail services as more attractive, as compared to local rail and bus services. Hence, vicinity to such stations was associated with a higher likelihood of choosing public transport, thus highlighting the importance of close vicinity to high-class services being of the highest importance for attracting passengers to public transport while perceived safety being of minor, yet significant, importance.
