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

The goal of this study is to assess and quantify the potential employment accessibility benefits of shared-use automated vehicle (AV) mobility service (SAMS) modes across a large diverse metropolitan region considering heterogeneity in the working population. To meet this goal, this study proposes employing a welfare-based (i.e. logsum-based) measure of accessibility, obtained via estimating a hierarchical

Ramp metering is known to be an effective freeway control measure that ensures the overall efficiency and safety of a highway system by regulating the inflow traffic on-ramps. Therefore, agencies are required to frequently assess the performance of their ramp meters. However, one major challenge for the agencies conducting ramp metering performance assessments is the lack of knowledge about data requirements

This paper investigates the impacts of high-speed rail (HSR) development on regional equity in China during 2007–2017. The equity in terms of economic output and HSR service is characterized at national, divisional (Eastern, Central, and Western), and provincial levels. The Gini indices associated with prefectures’ gross regional product (GRP) per capita, HSR connectivity and accessibility are measured

A claimed benefit of real-time information (RTI) apps in public transit systems is the reduction of waiting time by allowing passengers to appropriately time their arrivals at transit stops. Although previous research investigated the overall impact of RTI on waiting time, few studies examine the mechanisms underlying these claims, and variations in its effectiveness over time and space. In this paper

It is well known that faster and less-expensive transit systems with shorter walking distances, as well as less transfers, are associated with transit use. In this regard, recent studies have focused on estimating transit’s competitiveness and further suggested possible policy interventions. However, there were not much attention on measuring travel time and cost differences between transit and auto

For next-generation smart cities, small UAVs (also known as drones) are vital to incorporate in airspace for advancing the transportation systems. This paper presents a review of recent developments in relation to the application of UAVs in three major domains of transportation, namely; road safety, traffic monitoring and highway infrastructure management. Advances in computer vision algorithms to

Changes in the climatic conditions in the Arctic are opening new trading routes (Northern Sea Route & North West Passage) in this area. There is a growing importance of this theme in the conversation amongst transportation scholars. Indeed, the academic conversation about Arctic transportation is becoming a field of research in itself. The aim of this study is to look at this conversation and provide

We assess public support for three supply-focused transport regulations: vehicle emissions standards (VES), low-carbon fuel standards (LCFS), and zero-emissions vehicle (ZEV) sales mandates. We implemented a survey across several regions with varying policy experience, using representative samples from Canada (n=1,552) and the US state of California (n=484). The survey evaluated respondents’: (1) awareness

E-shopping for intangible services (e.g., eating out services, hairdressing, and visits to movie theatres) refers to searching and paying for services online, but it requires e-shoppers to travel to use these services. In theory, e-shoppers’ search space via the internet is less constrained by spatial attributes. As a result, spatial attributes may barely affect the distance and duration of trips resulting

Telework has been promoted for decades as one of the traffic demand management policies to alleviate congestion during peak periods and reduce work-related trips, along with other benefits. However, less clear is the role played by life stages (i.e., gender, marital status and parenthood) on telework behavior. This study investigated to which extent telework frequency associated with life stages, and

Consider a set of landmarks that are distributed in an emergency scene and each needs a specific number of robots in its vicinity. This paper presents a two-stage framework for deploying robots autonomously for such scenarios. In the first stage, a Two-hop Cooperative Virtual Force Robot Deployment (Two-hop COVER) technique is employed. It expedites the deployment process by establishing a cooperative

This paper quantifies the causal impact of differential pricing on the trip-scheduling of regular commuters using the Mass Transit Railway (MTR) in Hong Kong. It does so by applying a difference-in-difference (DID) method to large scale smart card data before and after the introduction of the Early Bird Discount (EBD) pricing intervention. We find statistically significant but small effects of the

Previous studies have explored the relationships between an individual’s use of information and communication technology (ICT) and their travel. However, these studies often focus on one specific type of travel and have not considered new forms of mobility, such as ride-hailing, that are enabled by greater ICT penetration. This paper focuses on how ICT use impacts an individual’s self-reported travel

While the importance of social influence on transport-related choices is commonly acknowledged within the transport and travel behaviour research community, there remain several challenges in modelling influence in practice. This paper proposes a new analytical approach to measure the effects of attitudes of peers on the decision making process of the individual. Indeed, while most of the previous

Finding ways to improve the service quality and consequently attract more passengers is a major concern for public transit officials worldwide. Given the fact that there is a glaring deficiency of service quality models in the literature, especially for developing nations, the present study develops interrelationships among service quality factors of Metro Rail Transit System (MRTS) in Delhi, India

Bike-sharing systems can be implemented to complete the coverage of public transport networks which could be insufficient to serve an entire urban area. Some methodologies that maximise coverage or accessibility are suggested in the literature. In this paper, we propose a bike-sharing stations location model that includes not only these issues but also equality aspects. The model aims to minimise inequalities

Bike sharing systems are increasingly promoted as a quick, accessible, affordable, and healthy transport alternative in a less car-dependent urban mobility system. The objective of this article is to elucidate the social and spatial inclusiveness of bike sharing, by exploring its intersectionality with user backgrounds and residential contexts, and its mechanisms of mediation by attitudes, mobility

How fair is the allocation of the infrastructure of a bike-sharing system (BSS)? Design guidelines for BSSs focus on optimizing the demand but not on who is served who is not. Areas where mainly young Caucasians, highly educated people live, and that have high access to community resources, presented greater access to BSS. Based on the concept of spatial fairness and its subjectivity, we developed

Peak–car is characterised by slower rates of growth, levelling off, or a reduction in car travel. Researchers have paid much attention to this topic recently. However, a consensus on possible explanations of the phenomenon remains elusive. Questions remain whether the drivers of travel demand are changing and projection methods need to be revised, or the peak–car is purely an external effect (e.g.

In this paper, a game-theoretical autonomous decision-making approach for efficient deployment of unmanned aerial vehicles (UAVs) in a multi-level and multi-dimensional assisted network is analyzed. The UAVs have directional antennas that work as wireless stations, which provide the best coverage for multiple ground mobile/fixed users. In general, UAVs work in a cooperative manner for achieving the

Combining traditional transport research tools with qualitative research methods, particularly ethnography, can contribute to our understanding of the complexity of mobility strategies, particularly their gendered differences. Ethnographic approaches can both explain and disentangle some of the results that emerge from travel and time use surveys, hence providing a more complete picture of how and

In recent years, the concept of carsharing is rapidly gaining popularity in China, and the round-trip carsharing has become a common mode. However, few studies have revealed the role of round-trip carsharing in users’ travel. In this study, the round-trip GPS data provided by a carsharing company in Beijing, China is used to analyze the users’ usage patterns based on their trip chains. Through the

The introduction of shared autonomous vehicles (SAVs) presents a wide range of challenges and uncertainties regarding their general acceptability. Hence, it is essential that transit managers have a good understanding of passenger satisfaction and of their behavioural intentions after experiencing a driverless vehicle trip. To this end, 1,062 face-to-face surveys were conducted following driverless

Dockless shared bicycles have become a popular mode of transportation for city dwellers in China. Despite its convenience, the dockless feature also creates new challenges, as users often park shared bicycles in a disorderly fashion, which places a burden on both city management and business operations. In a randomized field experiment, subjects receive general information via one of three interventions

Connected vehicles will enable the smart and autonomous transportation systems in the future. Cellular Vehicle-to-Everything (C-V2X) communication will provide wireless connectivity to enable large number of connected vehicle applications. Vehicles will receive traffic and infotainment contents from the city traffic command center using C-V2X communications. In this context, infrastructure Road Side

Peak and off-peak pricing strategies are an important policy tool used to spread peak demand in public transportation systems. This study uses an agent-based simulator (SimMobility Mid-term) to examine the impact of pricing (off-peak fare discounts) strategies used in Singapore. The aim of the paper is to demonstrate the capabilities of the simulator, and types of detailed performance indicators it

The growing demand for urban mobility highlights the need for relevant and sustainable solutions in cities worldwide. Thus, we develop and implement a framework to analyze the systemic impacts of future urban mobility trends and policies. We build on prior work in classifying the world’s cities into 12 urban typologies that represent distinct land-use and behavioral characteristics by introducing a

The 21st century has seen a cycling renaissance across Europe with many cities moving away from the car-centric infrastructure, urban design and planning policies prevalent since the 1950s. Southern European island cities, which exhibit certain characteristics considered as barriers to cycling, such as hot summers and high humidity, hilliness, and car-oriented culture and infrastructure however, have

This paper seeks to contribute to a critical dialogue on disruption and the sharing economy by reflecting critically on O Bike’s appearance and disappearance in Melbourne, Australia. Recalling the credulousness that attended the arrival of O Bike’s fleet between June 2017 and 2018, this paper gives primacy to considering whether O Bike was ever about bicycles and transport, showing how the scheme aligned

To solve the last-mile problem and promote low carbon transportation, hundreds of cities around the world have launched bike-sharing services. A growing number of studies have been mining bike-sharing data from different cities to understand bike-sharing systems. However, there is still a lack of comprehensive understanding of a bike-sharing network structure. Thus, this paper attempts to use complex

This paper presents a methodology to identify the economic impact of different policies for heavy vehicle routing and driver scheduling in long-haul full-load trips with intermediate stops for refueling and for regulation-driven meal and rest periods. This methodology can be used both as a planning tool to help policy-makers define policies through scenario simulations, and as an evaluation tool to

Transportation networks are facing severe congestion due to the increasing burden of traffic demand and unexpected incidents. Therefore enhancing the network capacity flexibility is the urgent task of transportation managers. Apart from the expansion of road links, economic approaches such as congestion pricing are more effective ways of improving network capacity flexibility. However, congestion pricing

Bikeshare systems are rapidly becoming more prevalent in metro and micropolitan areas around the world. However, low-income populations, people of color, and transit-dependent households are not highly representative of the bikeshare user’s profile. Some bikeshare programs in the United States, such as Divvy in Chicago, try to address this equity problem by promoting their systems among low-income

Pro-cycling interventions, and cycle hire schemes in particular, are often assumed to primarily benefit the privileged. This framing has played-out in academic research, with many papers exploring the relationship between cycling and existing inequalities. A growing body of evidence suggests that cycle hire schemes tend to serve wealthy areas and young, high income groups, mirroring inequalities in

This article helps explain why incentive-based contracts have failed in some cities. It also explicitly shows how contracted kilometer- and passenger-based payments affect transit service quality. First, we study how contract renegotiations in 2012 and 2013 affected quality related to service kilometers in the bus public transport system of Santiago, Chile. To do that, we analyze the evolution of compliance

Transportation, gender and social exclusion have increasingly come together in scholarly pursuits and policy agendas in Latin America and the Caribbean. The recognition of the gender dimension of sustainable mobility has opened a space to consider the role of women, especially of those facing poverty and exclusion, in this global agenda. However, research on the link between precarious occupations

The deployment of HSR services in the recent decades has been, arguably, the most significant innovation for intercity travel around the globe. HSR has brought impacts which have been widely studied in different countries in relation to the different socioeconomic, territorial and transport characteristics. This paper analyses the economic growth, the transport accessibility and the social impacts

The successful adoption of a product or service by its target market or users relies on delivering a product or service in line with their needs and expectations. Failure to do so will likely result in a low rate of uptake or use of the product or service. This study sought to identify the criteria by which potential users of a first-/last-mile automated bus (AB) service would evaluate the service

Background Variable message signs (VMS) have been widely applied to alleviate traffic congestion by providing spatiotemporal information related to traffic and network conditions to drivers. There is a debate on whether the VMS information would lead to the less-alleviation of congestion or congestion transfer to the adjacent roads in the different traffic congestion situations due to the inappropriate

The effects of social interactions on individual behaviour have been observed in many social phenomena, including travel-related behaviour involving direct or indirect contact with other agents. However, most formulations of urban transport policy assume that individual behaviour is independent of each other, which likely results in policy evaluation bias. Therefore, this study aimed at urban parking

Transport poverty is a growing concern in many developed countries. However, research on the determinants of transport poverty is relatively scant. We contribute to the debate on the determinants of transport poverty by presenting the first study to empirically examine the effects of ethnic diversity on transport poverty. Using 12 waves of longitudinal data from the Household, Income and Labour Dynamics

This study proposes an urban Bikeability Index (BI) to assess and prioritise bicycle infrastructure investments, and in turn, improve accessibility for cyclists. The contribution of this paper is twofold. First, we construct a BI that addresses particularities of the roads in cities of the Global South and considers the preferences, perceptions and socioeconomic characteristics by type of cyclist.

Denmark is one of the world-leading countries in terms of bicycle infrastructure and has a relatively good public transport system. Yet, a large share of commuters in the Greater Copenhagen Area still uses the car on a regular or semi-regular basis, causing severe problems of congestion and pollution. This article seeks to understand to what extent individuals’ perceived mobility necessities (PMN)

Government sectors often provide guarantees in build-operate-transfer (BOT) roads to attract private investments. Since a fiscal burden would be incurred from the contingent liability of issuing a guarantee, charging a fee for the guarantee is considered an effective remedy for management of contingent liabilities in practice. This study incorporates the charge mechanism for minimum traffic guarantee

E-scooters are rapidly changing transportation in US cities and university campuses. Hailed as a convenient, inexpensive solution for “last mile” and other short trips, e-scooters are available in over 100 US cities and were used for nearly forty million trips in 2018. Yet relatively little is known about e-scooter use, including who uses them, for which types of trips, and the perceived benefits and
