Abstract

Field trial results when applying a particular ramp metering strategy to an urban corridor network (Corridor Peripherique in Paris) including a motorway, a parallel arterial, and connecting radial streets are reported. The impact of ramp metering on corridor traffic is studied by comparative evaluation of several performance indices in the cases with and without control. The main finding of the field trial is that application of an efficient ramp metering strategy considerably improves traffic conditions not only on the motorway but also on the parallel arterial and the whole corridor network. This improvement is found to be traffic incidents.
