In this paper we use mixed logit specifications to allow parameters to vary in the population when estimating the value of time for long-distance car travel. Our main conclusion is that the estimated value of time is very sensitive to how the model is specified: we find that it is significantly...

We examine how changes in the geographic concentrations of Hispanic and African-American populations are correlated with changes in probabilities of airport noise, in Atlanta, during 2003 and 2012. We estimate ordered probit and locally weighted ordered probit regressions for three different...

Pedestrians are vulnerable in traffic, with frequently reported injuries and fatalities. These risks are believed to be correlated with socio-economic attributes such as age, income or education levels. For Korea, it is shown that elderly pedestrians have a higher mortality risk than other road...

Using Lorenz-type curves, means tests, ordinary least squares, and locally weighted regressions (LWR), we examine the relative burdens of whites, blacks, and Hispanics in Georgia from road and air traffic noise. We find that whites bear less noise than either blacks or Hispanics and that blacks...

Travel time savings are usually the most important utility component in transport infrastructure project evaluation. One of the controversial issues in research on the valuation of travel time savings is the assessment of small time savings. This article goes into this matter with specific focus...

We asked participants of a large-scale, real-life peak avoidance experiment to provide estimates of their average in-vehicle travel time for their morning commute. Comparing these reported travel times to the corresponding actual travel times, we find that travel times are overstated by a factor...

This paper considers travel mode choice for a range of journey purposes in Ireland using micro-data for 2009. Results suggest that demographic and socio-economic variables, location and public transport availability are important determinants of mode choice. The results also indicate an...

Costs of car ownership for company cars drivers and private car owners are very different. Car use, car choice decisions and preferences for car characteristics may therefore differ substantially between these two markets. In this paper, we present results of a study on the preferences of...

In this paper we study a group of policies aimed at discouraging the use of private transportation during peak hours, both directly and indirectly, by increasing the attractiveness of the only available substitute, the bus. This is done using a choice experiment constructed to find the answer to...
