China's new leadership recently announced its intention to reorganize its separate maritime law enforcement agencies under one governing body.
This paper presents results of an assessment of the state of research on decoupling the relationship between vehicle travel and economic growth.
The study of respondent heterogeneity is one of the main areas of research in the field of choice modelling.
Examines the security costs and benefits of a trusted traveler program, in which individuals who have been identified as posing less risk than others are allowed to pass through security checkpoints with reduced security screening.
Freight transport is a rapidly expanding and changing economic sector.
The calibration of choice models produces a set of parameter estimates and an associated covariance matrix, usually based on maximum likelihood estimation.
Reducing greenhouse gas emissions (GHG) is an important social goal to mitigate climate change. A common mitigation paradigm is to consider strategy "wedges" that can be applied to different activities to achieve desired GHG reductions.
Federal subsidies and policies to encourage plug-in vehicle adoption would produce more benefits at lower cost by targeting the purchase of vehicles with small battery packs.
In the 1990s, the usual assumption for an appraisal of road schemes in the UK was that total volumes of traffic were not affected by the capacity provided by the schemes. This assumption was questioned by the influential SACTRA committee in 1994.
Random coefficient models such as mixed logit are increasingly being used to allow for random heterogeneity in willingness to pay (WTP) measures.
This paper explores how alternative pricing and operating policies influence revenue generation, level of service, and travel time costs for high occupancy toll (HOT) lane facilities.
To reduce air emission and oil dependency impacts from passenger vehicles, strategies to promote adoption of hybrid-electric vehicles (HEVs) and plug-in hybrid-electric vehicles with small battery packs offer more social benefits per dollar spent.
The mean value of travel time savings obtained from a random parameters logit model estimated using the respondents who received the D-efficient design survey was closer to what is typically found in the literature.
Explore options for conducting a set of trials to test the feasibility of transitioning from fuel excise taxes to a system of road use charges based on vehicle miles of travel.
This paper elaborates upon and deepens the ongoing policy discussion of relationships between investments in transportation infrastructure and the nation's short- and long-term economic well-being.
The authors quantify a game-theoretic model of terrorist decision making to understand the role of nuclear detection technologies in deterring nuclear terrorism.
Identifies and assesses ways of making congestion pricing equitable.
In this article, we present an application of jointly estimated attitudinal and choice models to a real-world transport study, looking at the role of latent attitudes in a rail travel context. Our results show the impact that concern with privacy, liberty and security, and distrust of business, technology and authority have on the desire for rail travel in the face of increased security measures, as well as for universal security checks.
To what extent would people sacrifice their right to privacy and liberty in exchange for potentially safer and more secure travel? This paper uses a stated choice experiment to quantify individuals' tradeoffs between privacy and security within a real-life context, namely rail travel in the UK. Using a nationwide sample, the empirical analysis yields the importance of improvements in the security infrastructure and identifies areas of concern with regard to privacy and liberty controlling for travel related factors.
This article discusses the rationale for pricing strategies as an option for reducing traffic congestion in Los Angeles. Only pricing resist the effects of triple convergence. By increasing the cost of driving or parking in the busiest areas or corridors during the busiest times of day, pricing measures manage the demand for peak-hour travel, in turn reducing congestion. Once traffic flow improves, the prices remain in place, thus deterring excessive convergence on the newly freed capacity. Pricing strategies offer two additional benefits: it generates revenue to support needed transportation investments, and it enables more efficient use of existing road capacity, because roads on which traffic flows smoothly can carry far more vehicles per lane per hour than roads snarled in stop-and-go congestion. It is useful to think of pricing as a means of managing peak-hour travel demand rather than reducing it.
