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

    • Free pre-print version: Loading...

      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.

  • Optimizing bus line platform assignment across bus stations in Utrecht

    • Free pre-print version: Loading...

      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.

  • Investigating a small-sized bike-sharing system’s impact on transit
           usage: a synthetic control analysis in Tucson, Arizona

    • Free pre-print version: Loading...

      Abstract: The bike-sharing system (BSS) is an emerging travel mode that has attracted increased attention in recent years. One of the most critical reasons for this increased attention is that the BSS claims to solve the first-mile and last-mile problems, and can be used to connect with existing transit. However, some studies suggest that BSSs could compete with transit rather than collaborating. Previous studies only focused on large-sized BSSs, ignoring an analysis of the impact of small-sized BSSs. To fill this gap, this paper conducted a case study to investigate the impacts of introducing a small-sized BSS on transit (including regular bus, express, and streetcar) usage in Tucson, Arizona. All transit routes are categorized into two groups: treated routes with the defined buffer of BSS and control routes without BSS. Then, the synthetic control method (SCM) is employed to provide an unbiased comparison on the average ridership per stop of the treated transit routes. The ridership data and point-of-interest data are collected and used to synthesize virtual treatment transit routes. The results show that a small-sized BSS generally has a slight impact on the ridership of most transit routes because of the limited coverage. However, the streetcar experiences an increase in ridership and increases by 0.55 passengers as a result of 1 BSS trip. Furthermore, the relationship between a small-sized BSS and transit may be also dependent on whether a transit route can access areas having the densest BSS network. These findings suggest that the role of BSSs in an urban transportation system can be controlled by relocating the locations of BSS stations considering the characteristics of transit routes.

  • Public transportation vehicle selection by the grey relational analysis
           method

    • Free pre-print version: Loading...

      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.

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

    • Free pre-print version: Loading...

      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: 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.

  • Space–time classification of public transit smart card users’ activity
           locations from smart card data

    • Free pre-print version: Loading...

      Abstract: Smart card data from public transit systems has proven to be useful to understand the behaviors of public transit users. Relevant research has been done concerning: (1) the utilization of smart card data, (2) data mining techniques and (3) the utilization of data mining in smart card data. In prior research, the classification of user behavior has been based on trips when temporal and spatial classifications are considered to be separate processes. Therefore, it is of interest to develop a method based on users' daily behaviors that takes into account both spatial and temporal behaviors at the same time. In this work, a methodology is developed to classify smart card users' behaviors based on dynamic time warping (DTW), hierarchical clustering and a sampling method. A three-dimensional space–time prism plot demonstrates the efficiency of the algorithm.

  • Pedestrian safety at intersections near light rail transit stations

    • Free pre-print version: Loading...

      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.

  • Feeder-trunk and direct-link schemes for public transit: a model to
           evaluate the produced accessibility

    • Free pre-print version: Loading...

      Abstract: In a public transport network, a more intense integration between lines generally involves, on one hand, the reduction in the number of direct links, which forces users to perform more transfers, and on the other hand, the possibility of achieving a greater number of rides with the same whole mileage. Thus, the move towards feeder-trunk schemes produces both negative and positive effects on accessibility and on the quality of service perceived by users. That implies the need to evaluate accessibility realized on a territory by transit service patterns characterized by different levels of line integration. This research was focused on the development of an accessibility model able to estimate an equivalent travel time and to consider the discomfort resulting from possible transfers between vehicles and the benefits arising from available transit rides. As reported in this paper, the proposed model, that measures accessibility through an equivalent travel time, determines the latter as a function, in addition to the time spent inside the vehicle, also of the time and discomfort consequent to the transfers as well as of the number of supplied rides. With reference to the regional public transport, the values obtained by the calibration of the constants show how the waiting time has a weight for the user twice as much compared to the time spent on the vehicle, whilst the time required for the transfer has about a one and a half weight. Finally, the discomfort caused by each transfer is evaluated by the user as an increase to the overall travel time of about 3 and a half minutes. The calibrated model has been applied to a real case, in order to validate it and highlight benefits and limitations resulting from feeder-trunk supply patterns. The developed tool is useful in the design of a public transport service, especially in areas with weak demand, allowing to compare, in terms of produced accessibility, supply schemes with different levels of line integration, variable from direct-link type (also called point to point) to that feeder-trunk.

  • Cost of traffic congestion in Dhaka Metropolitan City

    • Free pre-print version: Loading...

      Abstract: This study attempts to estimate the cost of traffic congestion in Dhaka Metropolitan City of Bangladesh through collecting field level primary data. Traffic congestion is an important issue in the city. The study findings indicate that most of the commuters in the city travel more than 2 h/day. The calculated travel-related indices indicate that the commuters in the city have to spend more time on the road compared to an uncongested situation. They lose about one working hour per day on an average due to traffic congestion. Combining the elements of traffic congestion, this study finds that the calculated cost of traffic congestion crosses the benchmark of US$ 4 per day per commuter in the city. According to the perception of the commuters, pick up/drop off of passengers at any place is the most important cause, while ambulance stacking is the most severe impact of traffic congestion in the city. The commuters perceive more use of public transport as the prime solution to tackle the traffic congestion problem in the city.

  • Preference-based and cyclic bus driver rostering problem with fixed days
           off

    • Free pre-print version: Loading...

      Abstract: Given a set of predefined duties and groups of drivers, the duty assignment problem with group-based driver preferences (DAPGDP) aims at building rosters that cover all the duties over a predetermined cyclic horizon while respecting a set of rules (hard constraints), balancing the workload between the drivers and satisfying as much as possible the driver preferences (soft constraints). In this paper, we first model the DAPGDP as a mixed-integer linear program that minimizes the number of preference violations while maintaining the workload balance of the solutions within a certain margin relative to the optimal one. Since this model is hard to solve for large instances, we propose two new matheuristics. The first one restricts the search space by preassigning duties to rosters based on an optimal solution to the duty assignment problem with fixed days off. The second algorithm makes use of a set partitioning problem to decompose rosters consisting of a large number of positions into subrosters of smaller sizes. In a series of computational experiments conducted on real-world instances, we show that these matheuristics can be used to produce high-quality solutions for large instances of the DAPGDP (i.e., with up to 333 drivers and 1509 duties) within relatively short computational times.

  • Optimization of dedicated bus lane location on a transportation network
           while accounting for traffic dynamics

    • Free pre-print version: Loading...

      Abstract: A commonly used strategy to improve bus operations is to dedicate a lane for bus use only. However, this can reduce the available capacity for non-transit modes, in return increasing their delays and potentially creating queue spillovers. This paper proposes a bi-level optimization algorithm to determine dedicated bus lane locations on a network to reduce the total travel time of all network users while considering traffic dynamics. The proposed algorithm is applied to nine scenarios with different demand levels, demand patterns, bus routes, and base modal split values. The results show that, as expected, the implementation of bus lanes often increases car delay. However, the results also show that a net benefit in terms of total passenger travel time can be achieved by implementing bus lanes at strategic locations. The bus lane locations found as a result of the optimization process largely depend on the demand pattern, demand level, bus routes, and base modal split values. For an under-saturated demand scenario, the best performing solution finds that bus lanes should be implemented on almost all bus routes. For saturated and congested demand scenarios, links in the congested parts of the network are avoided in the best performing solution. However, the result of the sensitivity analysis shows that implementing bus lanes on links in the congested parts of the network can also be beneficial in certain scenarios.

  • 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.

  • Spatial data analysis approach for network-wide consolidation of bus stop
           locations

    • Free pre-print version: Loading...

      Abstract: Existing studies indicate that ideal spacing between bus stops improves the quality of service, travel time, and other transit service parameters. In this study, a network-wide heuristic methodology is proposed to optimize the number of stops in an existing bus network by eliminating redundant stops along each bus route in the network through an iterative process. It is postulated that ideal stop spacing can substantially lower the operating costs as it can reduce fleet size requirements without affecting the performance of the transit system. The proposed methodology attempts to eliminate undesired stops based on two vital inputs: (1) stop spacing, and (2) passenger boarding, which represent accessibility and travel time/delay. Potentially undesirable stops are eliminated recursively while their corresponding passenger boarding is redistributed across the adjacent stops. The process is repeated until ideal stop locations are identified. Stop location consolidation is evaluated using two performance indicators, i.e., in-vehicle travel time and access distance, which are considered for evaluating the performance of the modified bus network and comparing the total ridership with the existing network to justify the improvements. In other words, the ideal stop spacing is determined based on projected demand (ridership) loss and assessment of the performance indicators. The application of the proposed methodology is demonstrated using the bus network of the City of Regina in Saskatchewan, Canada. The findings of this research are expected to serve as a decision support tool for transit planners by offering additional flexibility to adopt appropriate bus stop spacing for an existing network.

      Abstract: This paper examines how different types of secondary activities, either offline or online, interact with travellers’ personal, travel, and spatial characteristics associated with the number of engaged secondary activities and commuters’ travel experience during a morning commute while using bus services of Trans Bandung Raya (TBR). By focusing on workers and students as productive groups of society and data collection in 2016, the results of this study found that activities with a high degree of attention and continuity in engagement will lead to a deactivation of other secondary activities during travel. While workers tend to deactivate other activities when they engage with social media or do online and offline socialising, students tend to have more active attention and continuity in engagements when they do online activities, particularly listening to music, engaging in social media, and playing games. Students in Indonesia tend to activate another secondary activities when they study on the bus such as reading a book or studying online using their gadgets. On the other hand, workers tend to undertake more activities while listening to music. Some results opposed with results from Europe and the US that collected the data in 2008–2012. In 2008–2012, the penetration effect might not be as massive as in 2016 and the types of online activites might not be as diverse as in 2016 which may make the results in Europe and the US different from this study. Different contexts among France, the Netherlands, Sweden, and Indonesia may let the results differ as well. In order to shift some potential travellers to use TBR, operators can promote the possibility of TBR as a platform to enhance workers’ travel experiences for working purposes and workers’ and students’ travel experiences for online socialising. However, TBR providers can alter travellers not to perform too many secondary activities during morning commutes in order to avoid people’s neutral experience. Providing more comfort space or facilities in the TBR might increase activities continuity during the trip, create relaxing conditions, and distract intense activity engagement.

  • Finding robust periodic timetables by integrating delay management

    • Free pre-print version: Loading...

      Abstract: This paper defines and solves a mathematical model for finding robust periodic timetables by proposing an extension of the Periodic Event Scheduling Problem (PESP). In order to model delayed and non-nominal travel times already in the timetabling step, the aim of this paper is to integrate delay management into the periodic timetabling problem and investigating the resulting problem (RPT). After revisiting both (PESP) and delay management individually, we introduce a periodic delay management model – an auxiliary model capable of evaluating periodic timetables with respect to delay resistance. Having introduced periodic delay management, we define the robust periodic timetabling problem (RPT). Due to the high complexity of the robust periodic timetabling problem we propose two different simplifications of the problem and introduce solution algorithms for both of them. These solution algorithms are tested against timetables found by standard procedures for periodic timetabling with respect to their delay-resistance. The computational results show that our algorithms yield timetables which can cope better with occurring delays, even on large-scale datasets and with low computational effort.

  • Time–space analysis to evaluate cell-based quality of service in bus
           rapid transit station platforms through passenger-specific area

    • Free pre-print version: Loading...

      Abstract: It is important to evaluate the quality of service (QoS) of bus rapid transit (BRT) station platform operation. Passenger-specific area (PSA) is used as a QoS measure which is determined by considering passenger activities separately. As passengers perform various activities on the same platform space, there is a need to evaluate BRT platform QoS by considering the activities collectively. When evaluating transit station platforms, many researchers calculated PSA for the whole platform area, while very few researchers highlighted the importance of evaluating the platform as small, partitioned areas. By considering these findings and gaps in the literature, this study evaluates QoS of the platform on a cell by cell basis using PSA. We use time–space analysis and passenger-minutes of each activity to develop a methodology to determine PSA, by considering stationary passengers, circulating passengers, and passengers overall. To evaluate platform QoS, we define threshold service levels using passenger-minutes of activities and Fruin’s QoS criteria. For the case study BRT station, we find that PSA varies significantly between platform cells. It is evident from the results that it is important to identify highly congested areas in the platform and apply measures to improve platform QoS.

  • Hierarchy-attribute decision making regarding public buses and private
           motorbikes: a case study in Ho Chi Minh City, Vietnam

    • Free pre-print version: Loading...

      Abstract: This study aims to identify the various attributes that significantly influence commuters’ decisions as to whether they should use public buses or private motorbikes in Ho Chi Minh City, Vietnam. Data were collected for analysis using a face-to-face survey of over 400 participants across a wide range of ages and occupations who use both public transport and private motorbikes in their daily lives. The decision tree technique and Weka software were used for data mining. The results indicate that commuters consider three vital attributes in deciding to stop using their own motorbikes in favor of public buses. The study also identifies decision rules for three commuter groups, including students, workers frequently traveling short-haul routes in the inner city, and workers frequently traveling long distances from the suburbs to the city center. The results are of significance for the identification of feasible measures and strategies to gradually encourage the use of public buses instead of motorbikes.

  • Zone-based public transport route optimisation in an urban network

    • Free pre-print version: Loading...

      Abstract: The majority of academic studies on the optimisation of public transport routes consider passenger trips to be fixed between pairs of stop points. This can lead to barriers in the use of the developed algorithms in real-world planning processes, as these usually utilise a zone-based trip representation. This study demonstrates the adaptation of a node-based optimisation procedure to work with zone-to-zone trips. A core element of this process is a hybrid approach to calculate zone-to-zone journey times through the use of node-based concepts. The resulting algorithm is applied to an input dataset generated from real-world data, with results showing significant improvements over the existing route network. The dataset is made publicly available to serve as a potential benchmark dataset for future research.

  • A route-planning method for long-distance commuter express bus service
           based on OD estimation from mobile phone location data: the case of the
           Changping Corridor in Beijing

    • Free pre-print version: Loading...

      Abstract: With the background of hyperurbanization and a jobs–housing imbalance in Beijing and other megacities in China, this study aims at developing a systematic toolkit of demand estimation and route planning for long-distance commuter bus lines. Taking the express bus services (EBS) in the Changping Corridor in Beijing as an example, this paper presents the use of a route-planning algorithm. Mobile phone location (MPL) data serves as a valid instrument for the origin–destination (OD) estimation, which provides a new perspective to identify the locations of homes and jobs. The OD distribution matrices are specified via geocoded MPL data. To minimize the aggregated travel time and attract potential passengers, this study subsamples long-distance commuting trips among the OD matrices by determining the operation distance threshold. The threshold can be solved by comparing the aggregated travel time of EBS to the travel time of local buses and private cars. Using the distance threshold and other operational parameters, we process an iterative computation to determine the length of routes, number of lines, and stop spacing and location. Compared to local buses and private cars, the planned EBS lines could reduce aggregated travel time by at least 20%. The results demonstrate that the method presented in this study is applicable and flexible. This paper may lead to new research directions for route planning of long-distance commuter buses. The limitations of this study and the future research agenda are also discussed.
