Due to the complicated environment there are various types of highway disasters in Shaanxi Province (China). The damages caused are severe, losses are heavy, and have rapidly increased over the years, especially those caused by flood disasters along the rivers in mountainous areas. Therefore, research on risk evaluations, which play important roles in the prevention and mitigation of highway di...

The solutions used to solve bi-level congestion pricing problems are usually based on heuristic network optimization methods which may not be able to find the best solution for these type of problems. The application of meta-heuristic methods can be seen as viable alternative solutions but so far, it has not received enough attention by researchers in this field. Therefore, the objective of thi...

In the fall of 1998, the Federal Highway Administration of the U.S. Department of Transportation initiated a series of studies related to the seismic performance of the U.S. national highway system. The research conducted under this study is intended to provide improved tools for evaluating and assessing the social costs and impacts of earthquakes on highway systems and bridges, and to reduce t...

Intelligent vehicle platoon driving is a process of the flexible formation based on the coordination between vehicle and highway in the intelligent vehicle-highway system, which can increase the controllability of traffic, simplify the complexity of traffic control, and ease the traffic pressure. It has been constructed that the intelligent vehicle platoon driving simulation experiment system u...

We study the wireless communication among highway vehicles in the newly-assigned 5.9 GHz Dedicated Short Range Communication (DSRC) spectrum. A vehicle-vehicle Location-Based Broadcast (LBB) communication protocol is designed to meet highway safety applications’ communication requirements. The analytical expressions of the performance of the protocol in terms of probability of transmission fail...

This paper argues that California’s self-help county tax legislation, which funds additional highway spending, amounts to a natural experiment that can be used to construct a valid instrument to determine highway congestion’s causal effect on the growth rates of GDP, employment, wages, and commodity freight flows for California counties. Our estimation results indicate that highway congestion h...

We examine various realistic generalizations of the basic cellular automaton model describing traffic flow along a highway. In particular, we introduce a slow-to-start rule which simulates a possible delay before a car pulls away from being stationary. Having discussed the case of a bare highway, we then consider the presence of a junction. We study the effects of acceleration, disorderness, an...

Perry Y. Li, Roberto Horowitz, Luis Alvarez, Jonathan Frankel and Anne M. Robertson 2 Department of Mechanical Engineering University of California at Berkeley Berkeley, CA 94720-1740 [email protected] Abstract Link layer controllers for the AVHS architecture proposed in PATH are derived using vehicle conservation ow models. Control laws are developed for three highway topologies: a...

This article proves the existence and uniqueness of a weak solution to a scalar conservation law on a bounded domain. A weak formulation of the boundary conditions is needed for the problem to be well posed. The existence of the solution results from the convergence of the Godunov scheme. This weak formulation is written explicitly in the context of a strictly concave flux function (relevant fo...

In line with the current development worldwide, the provision of public infrastructure in Malaysia is undertaken using the public-private partnership approach (PPP). This study explores the way in which accountability is demonstrated in Malaysian tolled highway sector. The study uses the case study approach to examine the implications of PPP arrangement on accountability in the tolled highway s...
