USE OF COMPUTERS IN TRANSPORT PLANNING AND TRAFFIC CONTROL IN BRITAIN IN THE MID-1990S

Most applications of computers in transport planning are implementations of transport modelling techniques, in particular the classic four stage model. However, computers are increasingly being used to collect and process the data required to run these models (pre-processing packages) and to produce additional calculations based on the standard outputs (flows, costs, matrices) by means of post- processing packages to assist appraisal of schemes and plans. Use of computers in transport planning is linked to their use in traffic management and control through the use of traffic assignment with detailed network models to estimate the effects of traffic management on the pattern of traffic on the affected roads. In traffic control, computers are used offline for design of road junctions and signal timing plans, and online for traffic-responsive control both at isolated junctions and where control at numerous junctions in a network is coordinated. Online use for signal control is being augmented in order to implement many of the possibilities offered by advanced transport telematics. (A) For the covering abstract see IRRD 873901.
