Résumé / Abstract
Fiedl trial results when applying the ramp metering strategy alinea 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 a number of performance indices in the case with and without control. The main finding of the field trial is that the application of an efficient ramp metering strategy considerably improves traffic conditions not only on the motorway but also on the parallel arterial and on the whole corridor network . This improvement was found to be even more accentuated in presence of nonrecurrent congestion caused by traffic incidents.
