The knowledge of link journey time is considered to be a valuable parameter in the provision of information to the driver and as a basis for urban traffic control and management. This paper describes methods to determine link journey times using single flow/occupancy detectors as used in SCOOT (Split Cycle and Offset Optimisation Technique). Data were collected from the loops in the form of SCOOT M24 messages fed on-line from the ROMANSE central processor at Town Quay, Southampton. Mechanistic and neural network approaches to journey time prediction are then compared to the actual data. The neural network approach is found better able to cope with saturated conditions. The mechanistic approach is unable to deal with increases in speeds between loop sites. For the covering abstract see IRRD 880251.
