CALIBRATING TRAFFIC MODELS ON TRAFFIC CENSUS RESULTS ONLY

The idea in the procedure is to calibrate the gravity model directly on the basis of the traffic census results. The only data required are traffic censuses, land-use patterns and road network descriptions. The traffic model has a simultaneous calculation of trip generation, trip distribution and assignment, giving a feedback from inter-zonal travel times to trip generation. The model is a rapid and inexpensive means of obtaining results with modified road networks and land-use patterns. The calibration method has been tested in a rural area.(a) /TRRL/
