A practical approach for estimationg origin - destination matrices reflecting TOLL collection system O-D matrices and counted link volumes with EMME/2

摘要

The objective of this study is to obtain more accurate Origin-Destination (O-D) matricws with exact data such as toll collection system (TCS) O-D matrices, counted link volumes and express bus O-D matrices by EMME/2. First, an effect region of each tollgate was set up. In and out volumes of each tollgate were distributed to zones in the effect region of it. The distributed O-D was assigned to the network composed of all tollgates and their effect zones. Next, we adjusted the regional O-D matrices excluding TCS O-D matrices in order to reflect the observed volumes considering the express bus and the assigned link volumes as additional ones. The assigned volumes with the estimated traffic-zonal O-D matrices produced the only 17.9
