  • A Study of Traffic Demand Estimation Model by Link Flows Using Dial's Probabilistic Assignment

抄録

<p>This paper presents a traffic demand estimation model by observed link flows on road network, combined with Dial’s probabilistic assignment method, which makes it possible to predict O-D trips and route traffics between every pair of nodes simultaneously. The model is performed through a simple iterative calculation so as to attain the best goodness of fit between observed and estimated link flows. Numerial examples reveal the characteristics and properties of the model. In particular, it should be noted that the observation error in link flows has a great influence on the accuracy in the estimates of O-D trips.</p>
