A Study of Changes in Traffic Patterns following Traffic Management Schemes.

TLDR: In this article, the authors present a comprehensive analysis of three origin-destination surveys carried out on the second Wednesday in May in three consecutive years 1989, 1990 and 1991, where every vehicle was tracked into, across and out of a demand-responsive signal control sub-area of Leicester city, whilst simultaneously collecting detector flow data.

Abstract: This paper presents a comprehensive analysis of three origin- destination surveys carried out on the second Wednesday in May in three consecutive years 1989, 1990 and 1991. The surveys were unique in that every vehicle was tracked into, across and out of a demand- responsive signal control sub-area of Leicester city, whilst simultaneously collecting detector flow data. The initial project had three main objectives. (1) To commission a computer link with the SCOOT computer at Leicester and to begin collecting and sorting data. (2) To carry out a registration plate survey to establish the origin destination traffic of actual traffic movement before the schemes were set up. (3) To establish a methodology to monitor continually and analyse SCOOT and other detector data. The research demonstrated that shifts in route patterns following traffic management and road schemes can be identified based on traffic flow data obtained from a demand- responsive signal control system. The study also suggested that drivers' responses to network changes do not always conform to expectations. This comprehensive research programme has produced the fundamental databases which allow further research and development of Informing Technologies for Transport.
