Using the Council’s Pre-Emptive Traffic Management System (PTMS) which collects speed data from approximately 30,000 links in Derbyshire, a Journey Monitoring Tool has been developed. This uses stored speed data to establish delays on each selected link (see later). The data fed into the PTMS is derived from floating vehicle data and within the PTMS, speeds are calculated and stored for every one of the 30,000 links. Amongst other purposes, the live display of conditions is used within the Council’s Network Intelligence Centre to inform operators of the current state of the network. The application is being used to assist late running buses, predict road based pollution episodes, and recently, with the GLF grant, has been adapted to provide a tool to enable the analysis of the performance of a junction, corridor and/or network.
