As a major ITS initiative, the Vehicle Infrastructure
Integration (VII) program is to revolutionize transportation
by creating an enabling communication infrastructure that
will open up a wide range of safety applications.
The road-condition warning system is a unique application of
VII technology, which is to provide drivers with real-time
information about unexpected roadway conditions ahead, such
as accidents, speed reduction zones, hazardous weather
conditions, etc. Currently, this application is still in the
conceptual development stages. The safety effectiveness of
the VII-based warning system need to be investigated under
various driving conditions. The possible influencing factors
on the performance of the VII based warning system include
the type of warning information, warning signal design,
driver acceptance level, the percentage of vehicles that
have VII communication capability and so on.
This project is to investigate the application of the VII
technology for highway crash prevention by providing real
time roadway condition information and to estimate its
benefits on highway safety under various roadway geometric
and traffic conditions.
