Research On The Travel Mode Selection Of Urban Residents' External Trip

Transportation is the essential precondition in urban external trip and a basic component of the city. In recent years, with the sustainable and steady development of our national economy, residents' trip demand had unprecedented growth, thus satisfying transportation demand resulting from social and economic development becomes the basic goal of constructing various traffic modes. The passenger volume of any traffic constructing projects depends on the social passenger transportation demand to the traffic corridors and the sharing ratio of passenger flow in the traffic system of this area. The sharing ratio of passenger flow of one transportation mode rests with residents' choices. That different travel mode choices will bring about different decisions, the distribution pattern of social traffic volume among the various traffic modes came into being sequentially. Therefore, the paper studied the choosing process of the urban external trip modes in several aspects of the following.Firstly, it is concluded that trip demand is not only by random, but also controllable and regular through analyzing the prevalent trip mentality and character of travelers, and the factors which might impact on residents' trip are also be involved.Secondly, it studied the issue of travel mode choice among intercity passages on condition of taking the dual end trip course into consideration, and regulated passage distance threshold of multiple city scale.Finally, an optimized model was obtained through introducing the generalized-time concept in, with numbering such factors as safety, comfort and punctuality in the disaggregate model, and the optimized model functioned in analyzing and forecasting the travel mode choice between Shanghai and Hangzhou in the year of 2020.
