A staggered-diamond Design for Automated/Manual-HOV Highway-to-Highway Interchanges

Directeur de l'Unité de Recherche Modélisation, Simulation et Simulateurs de conduite INRETS - MSIS

The ability to capture actual road conditions in an automated and cost-effective manner has increasedsignificantly with advances in sensor technologies, computer storage and data processing capabilities, andanalysis techniques. Likewise, the ability to utilize this information in a simulated road environment to (1)conduct research with human subjects regarding actual and propose...

Use of Acceleration-Deceleration Lanes

On the basis of various and recent research studies, it is apparent that highway designers must become more concerned with the relation­ ship between highway design and traffic behavior. An excellent example of current interest in highway design is the design of acceleration and deceleration lanes. In order to obtain maximum efficiency and safety in the operation of acceleration and deceleratio...

Seismic Vulnerability Study of the Us Highway Bridge Systems

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...

Car-driver Models for Manual and Automated Travel

This paper presents a model for manual and automated traac ow. The model is based on the abstraction of vehicle activities by the space and time taken up by the vehicle engaged in the activity. The manual driver model includes the activities of vehicle following and lane change and allows for diierent levels of aggressiveness of drivers. The parameters of the activities are calibrated with real...
