2003 Greater Vancouver Regional 2003 Greater Vancouver Regional Travel Time Survey Travel Time Survey Purpose of Travel Time Survey Monitoring • develop a regional congestion indicator for Corporate Scorecard and Regional Transportation Monitoring Program • develop matrices indicating travel times / avg. speed between regional activity centres for AM / PM / weekend peak periods Planning • calibrate the regional travel demand model’s (EMME/2) link speeds • develop a data repository of road travel performance of major corridors and infrastructure 9 Clark Lim, P.Eng.
