Route selection method taking outgoing delayed reaction into account

Abstract

The invention discloses a route selection method taking outgoing delayed reaction into account, and belongs to the field of transportation planning. The route selection method comprises the following steps: defining reference points of persons going out, confirming properties of the reference points, classifying the persons, analyzing risk preference coefficients of different types of person going out, furthermore calculating value functions and weight functions of the person going out by using related software, furthermore acquiring sensation values of different types of persons going out about candidate schemes, and finally, selecting routes by users going out according to the principle that the sensation values are maximized. By adopting the route selection method, the reference points of the users going out are defined, a classification method for the users going out is confirmed, the risk preference coefficients of different types of users going out are included into a route selection consideration range, a calculation method for the risk preference coefficients of the users going out is completed, and thus the route selection method can relatively well meet practices. In addition, the influence of actual outgoing time on the users going out is relatively better considered, and route selection behaviors of the users going out when actually going out are relatively well simulated.

Description

technical field [0001] The invention belongs to the field of traffic planning, and specifically relates to a method for simulating route selection behaviors of various travelers that can be applied in actual traffic scenarios. Background technique [0002] With the rapid growth of the number of motor vehicles in my country's cities, traffic congestion and its induced environmental pollution and traffic accidents have increasingly become bottlenecks restricting urban economic and social development. The most important question for travelers is: how to avoid traffic jams and reach their destination quickly by choosing a travel route. Due to the influence of traffic environment, travel experience and other factors, travelers may not choose the path with the shortest travel time in real traffic situations. Such behavior can be described by bounded rational behavior. [0003] Traditional research on route choice behavior is usually carried out based on expected utility theory or...

Problems solved by technology

However, the existing research rarely considers the differences in perceptions and preferences of travel expenses. Travelers with different travel purposes have different preferences for their own travel expenses, which may lead to differences in their route selection behaviors.

In addition, existing studies usually assume that all travelers are homogeneous, i.e., all travel users have the same reference point
