Abstract

This research aims at developing the technique for updating dynamic O-D matrices based on the information from probe-vehicles. However, probe-vehicle does not provide the information on the traffic counts and the observed speed varies among probe-vehicles even when the traffic condition is similar. We propose several techniques for estimating traffic counts from observed link travel speeds and the O-D matrices are updated based on the estimated traffic counts information. The results show that the O-D matrices updated by using the variance of estimated traffic counts or the number probe-samples as representing reliability of probe-information are more accurate than those by not using such indicators.
