System Specifications of an Affordable Area, Highway, or Route Specific Incident Alerting System Using RDS 2001-01-0812
In this paper we explore the system requirements and specifications of an affordable traffic alerting system that pertains mainly to traffic exceptions as incidents, construction, and warnings. It is feasible to implement such a system since the infrastructure needed to rapidly detect the occurrence of incidents is available on most highways. Our concern here is with the rapid dissemination of incident information to the affected commuters. We review our proposed traffic alerting service, and then focus on the RDS technology as an affordable medium for disseminating incidents information.
We design a software application suited for a traffic center, investigate the different Open Data Application (ODA) requirements of the RDS radio, and propose an RDS transmission group structure that will carry a specific incident information reliably under the RDS limited bandwidth constraint. We also look at the format of the routes list stored in the RDS radio, the receiver memory requirements, the routes file generation, and the search algorithm within the RDS radio for detecting incidents.
