Equilibrium Model under the Condition of Multi-Mode to Travel Choice and Mixed Traffic

摘要

This paper analyzes travel mode choice of equilibrium problems in three kinds of travel ways that constituted the way of car, bus, subway. The research subjects are urban residents in the peak period, in the process of travel mode choice selection basis for their own travel costs. Urban road don't have bus lanes, that is to say cars and buses in the mixture on the same roads. In order to make the residents travel mode choice more accord with people's actual travel characteristics, the travel cost function are considered main factors in the residents travel mode choice process. The urban resident's travel mode choice model was established in travel peak period and under the condition of cars and buses mixed driving and based on the user equilibrium theory and the traffic bottleneck theory. Obtain the maximum delay time, the number of trips and travel costs in travel costs equilibrium station. The rationality of the model was verified by a numerical example, the next was further discussed that the high value time of travel and low time value of travel traveler's impact on travel division and time delay are analyzed in comparison. The examples show that: Firstly, subway travel was to be choice of the majority of residents, whether they are high time value of travel or low time value of travel. Secondly, there are more high time value of travel residents choose car travel, compared with the low time value of travel residents.
