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....

The concentration of hospital capacities often involves closures of smaller hospital sites. While advocates of hospital concentrations emphasize increased quality of care and cost savings, some people may feel their health care is at risk. In this paper, I analyze the effect of 18 recent...

We assess the role of gender-conforming social norms in household decision-making and gender inequalities in the labor market with a parsimonious household model that endogenizes commuting time. Using the American Community Survey 2008-2019, we test the model predictions and find that women in...

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...

In der europäischen Raumordnung spielen insbesondere für die internationale Wettbewerbsfähigkeit von Regionen die europäischen Metropolregionen eine entscheidende Bedeutung. Die Bundesraumordnung hat diesen Gedanken aufgenommen, doch stellt sich die Frage nach der Abgrenzung der...

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...

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 studies the effects of areal cable cars on mode of transport, time use and employment in the metropolitan area of La Paz, Bolivia. Using an instrumental variables approach, we estimate local average treatment effects of cable car use for residents who use the system due to proximity...

We examine the relationship between the total size of an airline and its service quality by analysing over 4.8 million domestic flights within the USA in 2016. The total size of an airline is measured by its total market share, total amount of assets or total number of full-time equivalent...

Obtaining the routing distance between two addresses should not be a hassle in the current state of technology. This is unfortunately more complicated than it first seems. Recently, several Stata commands have been implemented for this purpose (traveltime, traveltime3, mqtime, osrmtime), but...

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 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...

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 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...

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...

Travel times for simple trips and cycles are analyzed for a storage/retrieval machine working in a one-dimensional or two-dimensional zone with taxicab geometry. A semi-random trip is defined as one-way travel from a known to a random location or vice versa. A random trip is defined as one-way...

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...
