We propose a theory-inspired measure of the accessibility of a city's center: the size of the surrounding area from which it can be reached within a specific time. Using publicly available optimal-routing software, we compute these "accessibility zones" for the 109 largest US and European...

In this study we have analysed policy interactions between an urban and a regional government which have different objectives (welfare of its own citizens) and two policy instruments (toll and capacity) available. Using a simulation model, we investigated the welfare consequences of the various...

The goal of this paper is the estimation of the effect of accidents on traffic congestion and vice versa. In order to do this, I use "big data" of highway traffic and accidents in England for the period 2007-2013. The data exhibit some remarkably stable cyclical pattern of highway traffic which...

Road transport will account for a large share of developing countries' future energy demand. This paper reviews the trends in road transport energy consumption in 12 countries (Group of Seven (G7) and BRICS) over the period 1973-2010. We report several stylised facts: road transport energy use...

Ride-share systems, which aim to bring together travelers with similar itineraries and time schedules, may provide significant societal and environmental benefits by reducing the number of cars used for personal travel and improving the utilization of available seat capacity. Effective and...

This paper discusses the main external costs related to road transport and the design of taxes to manage them. It provides an overview of evolving tax practice in the European Union and the United States and identifies opportunities for better alignment of transport taxes with external costs....

Traffic fatalities are the leading cause of mortality in the United States despite being preventable. While several policies have been introduced to improve traffic safety and their effects have been well documented, the role of transitory health shocks or situational factors at explaining...

Non-recurrent congestion is frequently caused by accidents and other incidents. We estimate the causal effect of incident duration on drivers’ time losses through changes in non-recurrent road congestion on Dutch highways. We demonstrate that incident duration has a strong positive, but...

The frequent occurrence of cargo theft in Brazil has considerably affected the highway transport mode. The utilization of these insurance have some relation with characteristics of transport companies (carriers), as well with the kind of service they sell. The main goal of this paper is to...
