Problem: Aurecon needed a fast, reliable communication and processing solution for receiving and responding to vehicle and driver sightings from various sources. The system needed to enrich collected data with additional information from external sources, determine additional actions, for example alerting on transgressions, and route output to interested parties.
Solution: Architecting a communication middleware concerned with retrieval and routing of traffic related data between integrating parties.
The Communication Logic Engine - or CLE as it is commonly referred to - is a system developed by NML for the Aurecon Group, for the purposes of retrieving and correlating information in near real-time about vehicles sighted by roadside sensors, more specifically ANPR traffic cameras, vehicle mounted cameras, and roadside “stop and approach” user events.
The system retrieves vehicle and driver information from eNaTIS, looks up information on taxis and busses, checks for transgressions in static data, calculates average speed over distance and checks for speed transgressions, and correlates and distributes the information to authorized external parties.
