Abstract

Traffic signals are present in the majority of European cities and represent a large and mainly untapped resource for management of traffic. MUSIC (Management of traffic USing flow Control and other measures) aimsed to prove that traffic signals can be seen as much more than simply a method of regulating flow at junctions. MUSIC showed that traffic signals can be intelligently used without the need for any extra infrastructure for a wide variety of transport goals, including public transport priority, traffic flow reduction and even pedestrian "comfort".

MUSIC was an EU funded DGVII project which demonstrated the potential for signal control policies which account for the rerouting of traffic. The aim of the project was to show that fixed-time policies designed off-line using computer models could deliver real benefits on-street Three cities were chosen for the MUSIC implementation: York (UK), Thessaloniki (Greece) and Porto (Portugal). In these cities the local authorities chose measurable transport targets which they wished to see met. Computer modelling was done to create signal timing plans to meet these targets. Finally, the results were assessed with on-street trials. This paper presents the final results of MUSIC, briefly details the modelling process which was used to create the timings and also passes on the experience gained in this demonstration project. The modelling process is not dealt with in full here. More details of this can be found in MUSIC(2000), Clegg(2000a) and Clegg(2000b) and also at the project web site http://gridlock.york.ac.uk/music/
