AN ASSESSMENT OF THE APPLICATION OF ON-LINE COMPUTERS TO CONTROL OF AN UNDERGROUND RAILWAY - A SIMULATION STUDY

This paper describes the method and summarizes the results of work within the operational research department of London Transport to assess the benefits that on-line computer control of signals on the Northern and Victoria lines would bring to passengers. From a simulation study it was concluded that reduction in travel times, waiting times and overcrowding could be achieved by computer control. In the simulation, travel time from Modern to Kings Cross was reduced by 1 min and passenger waiting time at stations reduced by up to 11 sec. The improvement derives mainly from better integration of conflicting movements. The total benefit to passengers over the Northern line is estimated to be 64,000 p.a. In addition there is the possibility of an increased revenue to London Transport from generated traffic. /Author/TRRL/
