The Michigan Department of Transportation (MDOT) has awarded a contract to Parsons Brinckerhoff (PB) for the design of a new fibre-optic communications network in metropolitan Detroit. The project is a multi-phase effort to build an MDOT-owned fibre-optic network for communications with the Detroit region’s intelligent transportation system deployment, including hundreds of closed-circuit television cameras, dynamic message signs and vehicle detection systems along regional freeways.
Houston TranStar, which has been collecting travel time and segment speed data using vehicle probe data since 1995, has an extensive coverage area that envelops most local commuters' daily freeway routes. However, expanding the existing Automated Vehicle Identification (AVI) system would be cost-prohibitive except for high-volume freeways. The partners of the Houston TranStar consortium needed a new method to measure speeds and travel times on arterial roadway systems and rural freeways. Instead of using co
Intelligent traffic cameras open up a host of possibilities for traffic planners and controllers alike. If traffic management centres (TMCs) around the world are to cope with the increasing demands of growing traffic flows while maintaining or improving transport safety and efficiency, then video monitoring will have to be supplemented by automated warnings of incidents or deviations.
According to Patrik Anderson, business development director at Swedish camera manufacturer Axis Communications, it is no
