The Research On Route Choice Behavior With Reference Points For Comfort

Travelers generally pursue fast and comfortable routes when making route choices.At present,the research on route choice behavior only considers the rapidity of the route,but does not pay attention to the comfort of the route.The diversity of route choice behavior preference is an essential characteristic of travelers,and studying the influence of this characteristic on the distribution of network traffic flow is a basic scientific problem to be solved urgently in the field of transportation planning.According to the characteristics of travelers’ route preference,travelers are divided into those who prefer the rapidity of the route,those who prefer the comfort of the route,and those who prefer the rapidity and comfort of the route.The thesis has studied the comfort of the route on the basis of the research of the rapidity of the route.Based on the prospect theory of behavioral science,the route choice behavior of travelers is analyzed.Under the decision-making mechanism of bounded rationality,the route choice models considering the action of rapidity reference points,comfort reference points and double reference points are established respectively to study the traffic distribution law of travelers with different route preferences when the traffic network reaches a stable state.The main contents of this thesis are as follows:Firstly,the route choice behavior of travelers with rapidity route preference is studied.In the thesis,quantifying the rapidity route with travel time,considering the influence of the traveler’s risk attitude in the process of the uncertain route choice,combining reliability and time budget to set the rapidity reference point.A stochastic user equilibrium model considering the rapidity reference point is constructed,and MSA algorithm is proposed to solve the problem.Through the sensitivity analysis of an example,the distribution law of the equilibrium flow of the rapidity route on the network under different parameters is studied.Then,based on the research of the rapidity of the route,the route choice behavior of travelers with preference of the rapidity route is studied.A stochastic user equilibrium model considering the comfort reference points is established by using congestion to measure the comfort of the route.Through the sensitivity analysis of an example,the distribution law of the equilibrium flow of the comfort route on the network under different parameters is studied.Finally,the thesis studies the route choice behavior of travelers with rapid-comfort route preference.Under the decision-making mechanism of bounded rationality,a stochastic user equilibrium model is constructed with the influence of route preference coefficient,which considers both rapidity and comfort reference points,to explore the travel distribution of travelers with different route preferences.The research shows that under the same conditions,the route choice behavior of travelers with the comfort route preference is significantly different from those travelers with the rapidity route preference,and the traffic distribution law of travelers with different route preference is different when the traffic network system reaches a stable state.In addition,the rapid-comfort route travelers show similar route choice behaviors to the other two types of travelers under certain circumstances,which can provide reference for traffic planning and traffic management departments’ traffic flow prediction work.
