NOTICE: An Architecture for the Notification of Traffic Incidents

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.
