Abstract
In this paper, a combined model of modal split and traffic assignment has been developed to evaluate pre-trip travel information provision strategies as travel demand management schemes. Three different information strategies are provided: user equilibrium base, system optimum base and in between them. These information provision strategies have been analyzed based on the levels of congestions and usage for the travel information. Only two modes, bus and car are used for evaluating and calculating modal split ratio. This ratio is implicitly calculated in the model using the logit form. We have found that the best effects on the information provision have been shown when the congestion level (V/C) is from 0.7 to 1.0, and the usage level of information is also from 0.4 to 0.6. As the usage levels become 1.0, the total cost changes to increase, which shows over-congestion, over-reaction and over-concentration effects on information provision strategy.
