The growth of social activities scale, the increase of population flow and flow velocity, and the continuous development of car industry have brought more and more heavy load to the highway intercity transportation and its management system. Against this backdrop, how to greatly improve the utilization rate of traffic infrastructure and transportation equipment by analyzing and forecasting the ...

Extended Abstract The Automated Highway Systems (AHS) project at UC-Berkeley is part of a comprehensive program initiated by the U.S. government under the Intermodal Surface Transportation EEciency Act of 1991 to improve safety and reduce congestion in the surface transportation system. UC-Berkeley's PATH program is a partner in the nine-member National AHS Consortium (NAHSC)heed Martin and Par...

This paper describes a prototype of a digital video image analysis system that measures the relative luminance of highway signs using nighttime video images taken by a camera mounted in a moving vehicle. The concept is that by using an inexpensive video camera and laptop computer mounted in a vehicle a measurement of the brightness and visibility of the sign can be made. The system uses real ti...

We comparatively assess the influence of adaptive cruise control (ACC) and cooperative adaptive cruise control (CACC) systems on highway traffic flow characteristics, with highway merging as an example. The primary goal is to study the design and implementation of vehicle-vehicle/roadside-vehicle communication system, which enhances an ACC system to a CACC one. In addition, the impact of market...

Based on previous studies of a highway reservation system, this paper proposed an auction-based implementation, in which the users can bid for the right to use a route during a certain period of time. This paper models the auction system with MATSim using an agent-based simulation technique. The agents adopt their own bidding logic in the auction, and the price converges after around 130 iterat...

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...

The natural environment affects the construction of desert highways. Conversely, highway construction affects the natural environment and puts the ecological environment at a disadvantage. To satisfy the variety and hierarchy of desert highway construction and discover the spatio-temporal distribution of the natural environment and its effect on highway construction engineering, an assessment o...
