The past decade has witnessed the confluence of Intelligent Transportation Systems and Vehicular Networks that is expected to change drastically incident detection and to provide timely dissemination of traffic-related information to the traveling public. As a first step in this direction we introduce NOTICE, a secure and privacy-aware architecture for the notification of traffic incidents. Using sensor belts embedded in the roadway, traffic-related messages and advisories are carried between belts by passing cars. NOTICE moves the responsibility for making decisions about traffic-related information dissemination to the infrastructure rather than leaving those decisions with the drivers, which may have incomplete or incorrect knowledge. Extensive simulation have confirmed that NOTICE can provide “up-to-the-minute” notification of traffic-related incidents to the various participants in the traffic.
