As part of the European TABASCO (Telematics Applications in Bavaria, Scotland, and Others) project, traffic-responsive urban control (TUC) strategies were developed and applied to the M-8 corridor in Glasgow, Scotland. Between 1997 and 1998 TUC strategies were deployed. Aaptive signal control, highway ramp metering, and dynamic message signs (DMSs) were used to balance network traffic loads on arterials and freeways during periods of heavy congestion.

  • Traffic signal timing at intersections were optimized every 2 minutes using linear-quadratic programming to balance the number of vehicles traveling on urban links.
  • Ramp meter wait times were adjusted every 60 seconds using the ALINEA (Asservissment LINeaire d’Entrée Autoroutière) strategy to maintain freeway flow downstream of merging locations.
  • DMS boards were used to provide alternative route information and equalize travel times between competitive routes.
