ABSTRACT Mobility as a Service (MaaS) promises a competitive transportation alternative to the private car such that mobility services are combined as packages and offered to users on demand. As this new mobility concept gains attention globally, many cities are eager to try it. This is a feasibility study to understand users’ preferences, potential demand and willingness-to-pay (WTP) for MaaS in suburban

ABSTRACT This paper introduces a new methodology to evaluate the performance of rural road networks when a link in the network is disrupted due to events such as natural disasters, accidents, and maintenance closures. As a measure of network resilience, we propose a simpler approach to quantify redundancy by introducing two indices that link the concept of road network redundancy with the increase

To inform the development of e-bike purchase incentive programs, the objective of this paper is to determine how key elements of program design (particularly rebate amounts and structure) are expected to affect new e-bike purchases. An aggregate demand model

ABSTRACT Incentive programs are widely used by airports as a marketing tool to attract new services. Empirical evidence regarding the effects of an isolated incentive program is yet to be explored. In this paper, we focus on airports located in Asia to detect the mechanisms, results and effects of the incentive program initiated by Narita International Airport, Japan. We present non-financial and financial

ABSTRACT Ride-sourcing, the use of private cars to provide on-demand mobility services, first appeared in San Francisco around the year 2010. Since then, transportation network companies (TNCs) who offer ride-sourcing services have expanded all around the world. By examining three case cities (San Francisco, Mexico City, Paris) we explain what facilitated this growth and how the regulation of TNCs

ABSTRACT To investigate the effects of different market penetration rates (MPRs) of intelligent vehicles – Intelligent Driving Model (IDM) for autonomous vehicles (AVs), Adaptive Cruise Control (ACC) for AVs, and Cooperative Adaptive Cruise Control (CACC) for connected and automated vehicles (CAVs) – in mixed traffic flows with human driving vehicles (HDVs) at intersections, three signalized intersections

ABSTRACT With the development of artificial intelligence and wireless communication technology, connected and autonomous vehicles (CAVs) have been treated as a promising strategy to increase road capacity and mitigate traffic congestion. Besides the technology of CAVs, innovative intersection design was also originally introduced as a countermeasure for dealing with traffic congestion at intersections

ABSTRACT Although attention to data fusion has undergone rapid growth since the late 1980s, there are still relatively few applications in transportation management. Most research has based fusion weight estimation on the variance of each data source, assigning high weights to low variance data, implying that low variance means high accuracy. We propose a data fusion methodology where weights are assigned

These service attributes have also become increasingly important for supporting the future development of contemporary society. At the same time, the system and its modes has been frequently affected by different

ABSTRACT Previous surveys of people’s attitudes toward automated vehicles (AVs) and transit integration have primarily taken place in large urban areas. AV-transit integration also has a great potential in small urban areas. This paper is based on a survey of people’s attitudes towards AV-transit integration carried out in two small urban areas in the US State of Wisconsin. A total of 266 finished

ABSTRACT Trip generation models are typically calibrated using zone-based aggregated data, despite some theoretical drawbacks pertaining to the use of aggregated data. This study demonstrates that models calibrated with disaggregated data not only have a better theoretical basis, but also forecast more accurate trip productions. In particular, optional trip purposes are focused on the calibration of

ABSTRACT The household travel survey (HTS) is the most widely used passenger travel data collection method, and web-based HTS is currently the most dominant survey mode. However, there is a lack of proper understanding on how much the web-based approach can be used without over-burdening respondents. This study investigates methods to improve web-based HTS data quality and to reduce response burdens

ABSTRACT In this paper, continuous timed Petri nets (CTPN) are used to develop a hybrid traffic model, where the network is modelled as a macroscopic model and calibrated by microscopic models. The concept of CTPN is used to build a modular model, where first the highway traffic system is decomposed into several systems, based on structural entities (highway segment, on- and off-ramp links), which

ABSTRACT In train rescheduling, the arrival and departure times of trains at stations are normally constrained by many operations rules that must be respected. Therefore, different methods were proposed to describe train operations for preventing train conflicts, especially concerning the safety headways. This paper develops a virtual resource-based method in place of the commonly used big-M method

Both subjective and objective measures of discretionary trips are analyzed. A number of attributes such as smartphone use for different purposes, individuals’ perceptions and attitudes towards smartphone use and travel, and built

ABSTRACT Over the past 20 years, shared-mobility services have become important transportation options, as they provide on-demand, door-to-door mobility without requiring vehicle ownership. Although low-income communities may benefit especially from the services due to their lower vehicle ownership and high dependency on public transit, scant research has been conducted exploring how frequently these

ABSTRACT New mobility services, including carsharing and automated vehicles (AVs), are changing mobility. Gathering evidence on the prospective adoption and uncertainty surrounding new technologies is critical, but technological changes outpace the speed with which planners can inform policy. This study demonstrates the feasibility of bridging planners’ programming and experimentation responsibilities

ABSTRACT Tradable credits for congestion management are a novel policy concept that is receiving increased interest in transportation research. This interest is mainly driven by the belief that the concept can count on stronger social support and hence has a better prospect for implementation than charging-based instruments. This paper is the first to provide an analysis of the social, political, economic

ABSTRACT Parking charges are considered to be a powerful tool for managing transport demand, as parking price is one of the most important factors impacting the travel decision-making process. This paper examines and quantifies the parking price impact on parking demand due to an increase in initial parking price as well as due to the real price decrease (inflation-adjusted) over time. Revealed preference

ABSTRACT Past decades have seen a ‘peak car’ phenomenon which is indicated by a decline in vehicle kilometers traveled (VKT) in many countries. Although the determinants of VKT have been widely discussed, the theoretical arguments remain unresolved, particularly on the role of transport policies, socioeconomic factors and the built environment. This paper aims to contribute to new evidence for these

This study investigates mobility and environmental impacts of CAVs on signalized intersections. With I2V communication capability, CAVs are able to receive the real-time traffic signal

ABSTRACT Algorithms for optimizing traffic operations at a single intersection consider mostly one objective function (often vehicle delays). Such an approach can lead to long pedestrian waiting times as well as reducing safety conditions at the intersection. In this paper, a multicriteria optimization approach to the single intersection traffic control problem is presented. The trade-off algorithm

ABSTRACT Positive impacts of car-sharing, such as reductions in car ownership, congestion, vehicle-miles-traveled and greenhouse gas emissions, have been extensively analyzed. However, these benefits are not fully effective if car-sharing subtracts travel demand from existing sustainable modes. This paper evaluates substitution rates of car-sharing against private cars and public transport using a

ABSTRACT Liberalised railway markets bring into play the economic interactions amongst three dominant interest groups: passengers as system users; public entities providing the track; and private firms operating the trains. Problems that arise are multi-criteria with multi-decision-makers who may be in conflict. Our approach to this problem is similar to that of a cooperative game-theoretic non-transferable

ABSTRACT Considerable observational evidence indicates that travel time, averaged across a population, is stable at about an hour a day. This implies both an upper and a lower bound to time that can be expended on travel. The upper bound explains the self-limiting nature of road traffic congestion, as well as the difficulty experienced in attempting mitigation: the prospect of delays deters some road

ABSTRACT Over the last two decades, motorcycle and motorised three-wheeler taxis have become important means of transport in many sub-Saharan African countries, including in rural areas. However, the emerging role of mobile phone technology in improving mobility in rural areas is currently under-explored in the literature.

ABSTRACT In this paper, commuters’ travel mode and departure time choice behaviors on a bottleneck-constrained highway with a peak-only bus lane (PBL) are investigated. The PBL occupies part of the capacity of the bottleneck when it is open. The capacity of the bottleneck for both auto and bus modes is time-varying. As the total number of commuters grows, we consider three regimes with different equilibrium
