Type III transponders are a suitable means for two-way communication between vehicles and road infrastructure. The transponders are small and are mounted on the interior of the vehicle windshield. Currently they are used for parking management and for data exchange for commercial vehicle border crossings. Because of these existing uses, there is a large number of Type III transponders already in use in commercial vehicles, and the infrastructure for the two-way communications is in place. Additionally, because of their current uses, Type III transponders are available in production quantities at competitive prices.
This project developed and evaluated a system for providing real-time, in-vehicle safety warnings to travelers through the use of Type III transponders. The development and evaluation performed in this project lead to recommendations for a full operation test deployment.
The project identified the appropriate structure and format for safety warning transmission to Type III transponder equipped vehicles. The Bearer Application Protocol (BAP) form data transmission developed the safety warning message list. An interface and software program provides and displays in-vehicle safety warnings. Finally, the
project made recommendations for a full test deployment.
