DRIVE V1011 Project A7.2. The Development of a Real- Time Control Strategy to Reduce Blocking-Back During Oversaturation Using the Microsimulation Model NEMIS.

This report summarises two months work carried out in Turin, in collaboration with MIZAR AUTOMAZIONE. The objective was to develop further the control strategies initialised in the DRIVE CAR-GOES project (DEL 24), also reported in the form of a technical note by Shepherd. This project: simulated a part of the A41 Finchley Road in London, using the microsimulation model TRAFFICQ. The aim of the control strategy is to reduce the effects of blocking back during oversaturated periods, by in effect responding to the traffic conditions and metering the traffic back upstream. The benefits should be, elimination of first order effects, such as wasted green time in the main direction and also second order effects, such as disruption to opposing and cross street traffic.
