Australia’s first Mobility as a Service (MaaS) trial commenced in April 2019 in Sydney, running for two years. The objective of the trial is at least twofold – to assess interest in various MaaS subscription plans through bundling public transport, rideshare, car share and car rental with varying financial discounts and monthly subscription fees, in contrast to pay as you go (PAYG); and to assess the

Gender is commonly identified as a key explanatory factor for travel behaviour. Since women’s role in societal structure has changed in the past few decades, the question arises as to whether the “gender” factor still plays a decisive role in differences in mobility within the working population. The aim of this paper is to extend the research on gendered differences in mobility by providing an in-depth

There has been a growing interest in the association between online activities and daily activity-travel patterns. An analysis of this relationship is even more crucial considering the major disruptions to out-of-home activity participation and travel due to the COVID-19 pandemic. This study contributes to the literature by exploring the relationships between Information and Communication Technology

Demand for public transport in cities has been and is projected to increase, putting existing transport networks under increasing strain. Nudging passengers to behave in certain ways through the creation of a salient social norm has the potential to be a cost-effective mechanism to manage transport demand. Transport for London (TfL) implemented in the second half of 2017 an experiment on one of its

This paper identifies the effect of passing distance laws on drivers’ perceptions and behaviors when passing bicycles. Using an instrumented bicycle, the study measured bicycle passing in a 25-h naturalistic field experiment using video recording and an ultrasonic distance-measuring device. In order to evaluate the effect of passing distance laws, the study examined jurisdictions with a three-foot

Environmental traffic restrictions are increasingly implemented in a large number of cities. One popular strategy consists in setting up Low Emission Zones (LEZs) that regulate or restrict the access to a dedicated urban area, for different classes of polluting vehicles. While LEZs are growing in numbers, there is a lack of objective evidence on when and how they actually contribute in reducing air

Replacing combustion vehicles with electric vehicles has been promoted by the Chinese government as a viable policy to reduce fuel consumption and greenhouse gas emissions. The purpose of this study is to examine factors that influence Chinese taxi drivers’ adoption of electric vehicles for living. This study takes the Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) as the theoretical

Studying road pricing acceptability has become increasingly relevant. Even though the policy has been effective in reducing the growing levels of congestion in several cities by curbing the indiscriminate use of the car, it still faces an initial rejection among the population in general. We discuss this issue based on a comprehensive review and set out to define what could be an acceptable road pricing

Ridesharing is critical for promoting transportation sustainability. As a new form of ridesharing services, ridesplitting has rarely been studied. Based on the Chicago ridesourcing trip data, this study explores how ridesplitting adoption rate (i.e., the proportion of ridesourcing trips with ridesharing authorization) varies across space and what factors are associated with these variations. We find

Despite its political, regulatory, technical, and environmental challenges , the recent trend of ice melting in the Arctic region has caused the increase in international shipping activities. Accordingly, this is supported by research focusing on a wide variety of shipping issues in the Arctic. Surprisingly, this is not the case in Arctic port research. That being said, considering the role of ports

Transport network criticality analyses aim at identifying important segments in a transport network. Such studies are often based on the utilitarian principle, where the criticality of a segment is assessed based on its contribution to the aggregate performance of the transport system. To allow for the use of alternative moral principles, I systematically operationalize concepts from the transport

Smartcard-based public transit systems have been widely adopted across many cities around the world. These systems generate large volumes of transaction records from individual passenger trips and contain the requisite information that enable the mapping, measurement and monitoring of fare equity. In this paper, we propose and apply new measures to evaluate fare equity using smartcard data to map changes

Given the burgeoning growth in bikeshare system installations and their growing adoption for trip making, it is important to develop modeling frameworks to understand bikeshare demand flows in the system. The current study examines two choice dimensions for capturing the system level bikeshare system demand: (1) total station level demand and (2) distribution of bike flows from an origin station across

Despite many qualitative discussions about the benefits of free-floating bike-sharing systems (FFBS), high-resolution and quantitative assessments about the economic benefits of FFBS for users are absent. This study proposes an innovative trip-level inference approach for quantifying the economic benefits of FFBS, leveraging massive FFBS transaction data, the emerging multimodal routing Application

Previous studies on the built environment and urban vitality often assume that they follow a pre-defined (mostly linear in parameters) relationship, and few studies substantiate whether high-quality transit (T) and supportive land development (D) are synergistic to vibrant urban places. This study employs gradient boosting decision trees to examine the irregularly non-linear associations between the

Participatory Value Evaluation (PVE) is a new method to assess the desirability of government projects. In a PVE, individuals select their preferred portfolio of government projects given a constrained public budget. Individuals’ preferences for (the impacts of) government projects can be determined based on these choices. The obtained preferences can be used to rank government projects in terms of

This paper proposes a multiple discrete continuous (MDC) choice modelling framework with the following features for analyzing individuals’ time use decisions: (a) accommodates non-additively separable (NAS) utility functions with respect to time allocation across different non-work activities, (b) considers both time and money constraints by integrating the two constraints into a single economic constraint

We report the results of a stated preference study (N = 1,934) carried out at the end of 2018 on consumers’ choices between electric cars and petrol cars in Italy and Slovenia. We estimate a hybrid mixed logit model that takes into account vehicle, infrastructure and policy attributes and two attitudinal attributes, i.e. environmental awareness and electric car knowledge. We find that purchase price

In the era of sharing economy and the mobility-as-service, the last mile delivery system is undergoing revolutionary changes with emerging a lot of new operation modes and policies. The crowdsourced delivery mode has become a novel and popular practice in the last mile delivery industry. This mode brings a novel way for facilitating the efficiency of last mile delivery on the basis of the shared mobility

The research reported in this paper focused on studying various aspects of freight mode choice in the continental United States (US) including the influencing factors, the development of econometric models to assess the impacts of public-sector policies and changes in market conditions. To gain insight into this complex subject, the team used qualitative and quantitative research techniques. The qualitative

With the anticipated introduction of self-driving vehicles, new challenges arise for urban transport- and planning authorities. This study contributes to the efforts of formulating the potential opportunities and threats stemming from the introduction of larger fleets of self-driving vehicles to our cities, and what action could be taken by transport authorities to shape this introduction beneficially

Many studies have been conducted to examine the direct effects of airports on local economic development, however, there is little solid evidence on spatial spillover effects and much less in the context of China’s airport system. To fill this gap, this paper analyses the spatial spillover effects of China's main hub airports on economic development. Our results indicate that air passenger traffic

Public bicycles have been touted as a convenient, environmentally friendly, and sustainable travel mode. Public bicycles have also been viewed as one part of a holistic solution to reducing negative transportation externalities. However, government and private entities need a better understanding of factors influencing user adoption of public bicycle systems. In this survey study, 470 prospective public

This study analyses the possible existence of spatial interdependence in port authorities’ capacity expansions in the port industry. We propose a dynamic model that allows quantifying the degree of port authorities’ interdependence in capacity decisions and simulating a hypothetical scenario of cooperation agreements among different port authorities. The econometric specification is based on a structural

Existing literature has confirmed that severe weather events have a negative impact on travel behavior. Considering the features of long distances and long durations, intercity travel may be affected by the weather at the origin (O) point and at the destination (D) point. This paper aims to reveal the relationship between weather and OD volume of intercity travel by additional considerations of the

To relieve road congestion, a variety of transport demand management measures (TDM) have been implemented all over the world. The success of these measures has been found to depend at least partially on users’ perception about them. Several articles have jointly addressed the acceptability of public transport improvement (carrot policies) and road pricing (stick policies). However, these research works

Several studies have made manifest that involvement with public transport play a key role in the intentions of its use. However, conflicting models exist in the literature about involvement’s role in the relationship between service quality, satisfaction and behavioral intentions or loyalty. Previous studies suggest all possible roles: antecedent, mediator, moderator and direct effects. A structural

As Multi-UAV systems are still in early design stages, threat modeling can play a crucial role in attaining the “secure by design” notion in such complex cyber-physical systems (CPS). In this paper, we employ a threat modeling methodology, known as threat trees to analyze and enumerate threats impacting the Internet of Drones (IoD) architecture. The proposed threat tree is meant to provide a holistic

Drones flights have been investigated widely. In the presence of high density and complex missions, collision avoidance among swarm of drones and with environment obstacles becomes a challenging task and indispensable. This paper aims to enhance the optimality and rapidity of three dimensional IoD path generation by improving the particle swarm optimization (PSO) algorithm. The improvements include

This paper studies the impact of offices on urban freight traffic. Research on freight activity generated by offices is very limited because they are not seen as important contributors to urban freight traffic, and because the amount of deliveries per office is very small compared to the number of deliveries per establishment in freight-intensive sectors (e.g., retail, wholesale, manufacturing). However

China Railway Express (CRE) is one of the most important constituent parts of the Belt and Road Initiative. Freight demand analysis is fundamental as a basis for the operational strategy of CRE and the investment policy along the CRE-routes. Most of the existing relevant literature has focused on the organization of the train operations of CRE, with little research related to demand analysis. This

We analyze the complex travel behavior of workers who utilize public transit as part of their work tours (“transit commuters”). Here, complex travel behavior is defined in terms of tours, where a tour is defined as a sequence of trips and activities that begins and ends at the same location and a work tour contains at least one non-home, work activity. The objective of this study is to investigate

Public bike-sharing schemes (PBSS) or bicycle hiring schemes (BHS) are now available in many cities globally. The purpose of this paper is to provide an outline for the feasibility of implementing PBSS in Bangladesh, particularly in Dhaka city, discussing the major issues that need to be considered. For doing this, PBSS that are already available and operating in six different cities - London, Paris

Traffic engineers are making efforts to mitigate congestion and to improve efficiency at intersections. The symmetric intersection (SI) can increase the capacity of intersections and is economical, practical, efficient and convenient. The pedestrians’ crossing patterns tailored for SI has not yet been studied. This paper not only develops three pedestrian crossing patterns but also analyzes crossing

To understand the route choices of public transport users, it is important to know the information available to them, and the context present at that moment. In fact, each choice situation in a transport network has different characteristics and possibilities, also depending on the current status of the transport network. In this regard, travel diaries based on tracking technologies can capture precise

In the case of revenue uncertainty, the static capital structure predefined in the feasibility stage of Public-Private Partnership (PPP) cannot satisfy the need of dynamic adjustment in the capital structure of Chinese PPPs during project operation, thus deteriorating project financial viability in the long run. Therefore, this paper aims to propose a Monte-Carlo optimization model that can enhance

Ensuring a high level of customer satisfaction with public transport is a key objective for transit agencies wishing to maintain and/or increase service uptake. Importance – Performance Analysis (IPA) can be used to identify gaps in the performance of public transport service attributes relative to their importance. However, this approach is often used without adequate consideration of its validity

The current paper contributes to the literature on the relationship between economic growth, fuel prices, and the demand for gasoline and diesel within the transportation sector by assembling a wide panel dataset of fuel consumption and prices for 35 OECD and 83 Non-OECD countries. The unbalanced data spans 1978–2016, with the full 39 years of data for 36 countries. In addition, our dynamic panel estimates

The alternative public transportation options such as subway, bus, or taxis compete with each other to attract passengers. The competition depends on many factors such as travel time, reliability and convenience. Convenience is a collection of attributes affecting the attractiveness of the service including access and egress easiness, service frequency, crowding, comfort and information availability

Safety is always the first concern for a ship’s navigation in the Arctic. Ships navigating in the Arctic may face two main accident scenarios, i.e., getting stuck in the ice and ship-ice collision. More specifically, excessive speed may cause severe hull damage, while a very low speed may lead to a high probability of getting stuck in the ice. Based on this multi-risk perspective, an integrated risk

The aviation industry is one of the fastest-growing sectors in producing carbon emissions. In order to reduce its carbon footprint and to respond to the increasing number of people concerned about the impact caused by air transport on climate change, the International Civil Aviation Organization (ICAO) has recently passed the “carbon neutral growth from 2020” resolution requiring that the global net

China is now a global leader in the construction of high-speed railways (HSRs). However, few studies have focused on the actual operational performance of China’s HSR system, which is revealed by high-speed train (HST) services. This paper investigates the spatial distribution of China’s HST services, and the influencing factors are analyzed by using multiple stepwise regression. The results indicate

Air cargo is vital to the modern supply chain because it provides efficient and timely delivery. In the past decade, the development of high-speed rail (HSR) in China has resulted in significant impacts on air cargo traffic, which has long been neglected by the existing studies. In this research, we quantify such impacts using HSR entry dummy variables and employ a panel regression approach to capture

No existing automated vehicle can operate in all conditions and environments. In order to allow unmanned operation of automated vehicles in all conditions, many developers have the capability for human drivers to operate the vehicle from a remote location using wireless communication. This practice, referred to as remote operation or teleoperation, is prevalent among industry, yet has received little

We explored the structure of public attitudes on whether self-driving vehicles (SDVs) should be allowed on public roads, through a four-way typology of attitudes (positive, negative, ambivalent, and indifferent). We segmented participants based on a single item, according to which participants allocated themselves to one of the four attitudinal groups, and characterized the demographic and psychological

User perception plays a critical role in pedestrian infrastructure usage. Indeed, the perceptional influence varies across individuals, and it is imperative to consider their response heterogeneity in modelling individual travel intentions. The present study develops a novel framework to understand the pedestrian perception, and further identify their impact on future travel decisions. In this framework

With the rise of smart cities, a number of new mobility services have emerged to drive changes in built environment policies. Up-to-date demand models are needed to capture the impact of these policies on emerging mobility-enabled travel patterns. The study explores modeling requirements to assess the impact of such built environment policies. A synthetic population of New York City with a tour-based

As a special case of multitasking, travel-based multitasking typically refers to conducting a set of in-vehicle activities while traveling. Travel-based multitasking has an indisputable influence on offering a pleasant travel experience to transit users during their rides, given that they can use their travel time to perform desirable activities and gain benefits in various form. For instance, the

Local transit accessibility measures are important tools used by planners to understand the effects of changes to public transit systems. Several local transit accessibility measures exist in the literature, however, it is not clear how these measures relate to public transit usage. Therefore, the aim of this study is to evaluate several transit accessibility measures that are commonly used in the

Passenger activities in terminals can be understood better in the current era, when sensors are pervasive throughout airports. This study demonstrated the usefulness of combining multiple-source data to investigate passenger behavior in airports. Objective time-use and terminal activity participation data of 266 air passengers’ behavior at Taipei Songshan International Airport were collected from beacons

Despite numerous theoretical models, only limited field experiments have been conducted to investigate traffic oscillation propagation, and the relationships between traffic oscillation features (e.g., period, speed variation, spacing and headway) have not received quantitative analysis. This study conducts a set of field experiments designed to inspect such relationships. In these experiments, 12

Increasing ridership in the urban rail systems in major cities is outpacing their designed capacity. Promotion based demand management can facilitate better utilization of the available capacity of the existing system when the investment and opportunity to expand the system are limited. While several studies address short-term behavioral responses to such promotions using before and after analysis

During the last decade, the use of free-floating carsharing systems has grown rapidly in urban areas. However, little is known on the effects free-floating carsharing offerings have on car ownership in general. Also the main drivers why free-floating users sell their cars are still rarely analysed. To shed some light on these issues, we carried out an online survey among free-floating carsharing users

The tourism industry is rapidly growing, and the massification of certain areas is jeopardising the environment. Certain roads in protected areas or near tourist attractions are experiencing an increase in traffic volumes, leading to higher pollution and noise levels and greater discomfort in the travel experience. To recommend measures intended to ensure a sustainable tourism industry without compromising

Understanding metro passenger’s travel plan choice behavior under unplanned service disruptions is vital for transit agencies. It allows capturing the changes in the demands of the passengers, adopting measures aimed at minimizing the impact on the transit system, and ensuring the safety of the interrupted passengers. Different from planned metro service disruptions, unplanned service disruptions cannot

Origin-Destination matrices obtained from smartcard data are very valuable because they contain vast amounts of information and can be obtained at a very low cost. However, they can only account for trips paid by smartcard. Trips paid by other means, as well as non-paid trips, must be incorporated using additional information. This paper discusses the biases that are introduced due to fare evasion

Attitudes towards travel mode choice have been regarded as bi-polar evaluations of travel options that remain stable across time and context. Intra-personal attitudes can be variable, becoming more or less salient and changing in strength or valence across decisional contexts. This study draws on theoretical underpinnings of attitudinal ambivalence, which proposes that a person can hold two-dimensional

This study examines the relationship between transport, logistics, foreign direct investment (FDI), and economic growth in developing countries over the period 2000–2016. A global panel data comprising of 46 developing countries were collected and divided into three sub-panels: European and Central Asian countries (ECA), Middle East, North African and Sub-Saharan countries (MENA-SSA), and East Asian

When benefits of proposed infrastructure investments are forecasted, residential location is usually treated as fixed, since very few operational transport models are able to forecast residential relocation. It has been argued that this may constitute a source of serious error or bias when evaluating and comparing the benefits of proposed infrastructure investments. We use a stylized simulation model

In the past three years, many studies have been conducted on dockless bike sharing (DBS) around the world. However, these studies have focused minimally on the problem of damaged bicycles, which is critical to a DBS system’s operating efficiency, user satisfaction and platform sustainability. The objectives of this study are to develop an integrated theoretical framework based on the normative activation
