This study examines if the Gini coefficient, which is a widely used measure of income/wealth inequality in a country/society, could be used as a measure of travel time reliability. To be considered a valid measure of travel time reliability, the Gini coefficient should at least agree with...

Over the last six decades, a large quantum of studies has explored the value of travel time savings(VTTS). The travel time savings constitute a significant proportion of many transport improvements, cost-benefit analyses of transport services, traffic forecasting models, and congestion pricing...

This paper uses a difference-in-differences strategy and an event-study analysis to evaluate the effect of Uber entries on vehicle miles traveled (VMT) in 346 US MSAs between 2011 and 2017. Empirical results demonstrate that Uber entries have no significant effect on the total VMT in a city....

This paper presents a travel time model for multi-deep AS/RS, which determines the average travel times during a single command storage or retrieval and a dual command cycle. The model can determine the relocation probability, the number of expected relocations and the travel times in storage...

The user-written command georoute is designed to calculate travel distance and travel time between two addresses or two geographical points identified by their coordinates. Since its conception and description by Weber and Péclat (2017), the command has been gradually maintained and enriched....

In this paper, we examine a vehicle routing problem with a makespan objective incorporating both stochastic and correlated travel times, which is usually not considered in routing problems. As an alternative to simulation, we develop an approach based on extreme-value theory to estimate the...

Conventional outcomes report cards-- public disclosure of information about the patient-background-adjusted health outcomes of individual hospitals and physicians -- may help improve quality, but they may also encourage providers to "game" the system by avoiding sick and/or seeking healthy...

We provide a first estimation of ground travel times between Spanish provinces circa 1867 (with a basic indicator of generalized transportations costs [GTCs]) and the geolocation of railway stations and stops between 1848 and 1930. This is work in progress that will be periodically updated with...

This paper outlines the rationale, methodologies, key findings and policy implications of the national Value of Travel Time Savings (VTTS) study conducted in Britain during 2014-15. The study found VTTS varied with distance, trip purpose and mode of travel but not with worthwhile use of travel...

This paper reports the theoretical and empirical evidence on the distributional effects of Express Lanes. It also provides evidence of how they affect congestion, both in the Express Lanes themselves and in the parallel general-purpose lanes. The paper also helps put Express Lanes in context by...

This paper discusses the importance of reducing the space consumption of car traffic as opposed to simply reducing individuals' travel time. It highlights the role of app-based mobility services in reducing urban congestion from a spatial perspective and the importance of shifting the focus from...

Between 2009 and 2016, Nigeria witnessed insurgency attacks from such militant groups as Movement for the Emancipation of Niger Delta (MEND), Movement for the Actualization of the Sovereign State of Biafra (MASSOB) and O'odua People's Congress (OPC). The most vicious and infamous threat yet was...

Accurate travel time prediction is of high value for freight transports, as it allows supply chain participants to increase their logistics quality and efficiency. It requires both sufficient input data, which can be generated, e.g., by mobile sensors, and adequate prediction methods. Machine...

This paper explores the applications of machine learning for predicting the travel time in the ride-sourcing networks using the Uber movement dataset. Using the Python programming environment, a case study is presented to analyze the travel time of the ride-sourcing services from the central...

Few issues are more important to welfare estimation with recreation demand models than the specification of the opportunity cost of travel time. The two most common approaches to specifying this cost treat it as a fixed fraction of the recreationist's wage, and either estimate the fraction (done...

This paper explores the impact that advances in Information and Communication Technology (ICT) have on the behaviour of transport users and their mode choice habits in Seoul. It discusses the stated preference survey conducted in Seoul and the analysis carried out using the discrete choice...

Integrated interoperable rail systems facilitate high speed rail (HSR) train movement on conventional intercity lines, and vice versa. Hence, for such rail systems, it is preferred that HSR stations are located at existing intercity rail stations. However, all existing intercity stations may not...
