摘要 OD matrix estimation of freight transportation is important in urban traffic and logistic planning. In this process, passenger traffic does not require participating in the mode of distribution and estimation. Thus, the accurate calculation of the impedance caused by passenger traffic on freight vehicles on the road is one of the urgent problems in OD matrix estimation of freight transportation. One of the functions of the Bureau of Public Roads (BPR) is conducting research on road traffic impedance. Flaws were determined in the BPR function. Thus, an approach to improve initial impedance must be suggested. This study proposed the impedance model. The parameters of different road types were calibrated, and the calibration for different methods and road types was comparatively analyzed. Methods of improving the BPR function were studied to estimate the OD matrix of freight transportation under certain conditions.

Abstract：OD matrix estimation of freight transportation is important in urban traffic and logistic planning. In this process, passenger traffic does not require participating in the mode of distribution and estimation. Thus, the accurate calculation of the impedance caused by passenger traffic on freight vehicles on the road is one of the urgent problems in OD matrix estimation of freight transportation. One of the functions of the Bureau of Public Roads (BPR) is conducting research on road traffic impedance. Flaws were determined in the BPR function. Thus, an approach to improve initial impedance must be suggested. This study proposed the impedance model. The parameters of different road types were calibrated, and the calibration for different methods and road types was comparatively analyzed. Methods of improving the BPR function were studied to estimate the OD matrix of freight transportation under certain conditions.
