10/27/11 - Development of a Traffic Information and Dissemination System for Work-Zone Environments
Update: 2011-10-31
Description
To save lives and prevent injuries on U.S. highways, vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication is essential. In this seminar, M. Imran Hayee reviewed the architecture, functionality, and field demonstration results of a newly developed V2I communication system that incorporates V2V assistance. The system, which relies on dedicated short-range communications technology, was developed to improve traffic efficiency and increase safety in congested work-zone areas.
The system can automatically acquire important traffic information—such as travel time and the starting point of congestion—and relay it back to drivers approaching the work zone. It uses a single roadside unit to collect traffic data from vehicles traveling on the road that are also exchanging information with each other. Field demonstration results indicate that the system can adapt to dynamically changing work-zone traffic environments and can cover larger work-zone areas than a system using V2I communication without V2V assistance.
