Study On Multi-Day Activity-Travel Behavior Considering Traffic Convenience

With the acceleration of China’s urbanization process and the continuous transformation of urban transportation system,urban transportation travel has shown diversity and combination characteristics.The behavior pattern of travel groups has changed from a single form of travel to a combination of multiple modes of travel,such as park-and-ride(P&R,Park and Ride)travel.Although the flexibility and diversity of travel mode greatly improve the breadth of urban residents’ choice of travel mode,it also makes urban residents’ choice of travel more difficult.Convenient travel mode can not only greatly shorten the travel time of residents,but also improve the public’s satisfaction with urban travel services.In addition,the current travel path planning system still has many problems,for example,travel planning does not fully consider the coordination of traffic convenience factors and the difference in travel activity demand,which makes the overall accuracy of the planned route plan poor and personalized,and it is increasingly difficult to meet the actual travel needs of urban travelers.Convenient transportation system not only enables urban residents to travel conveniently objectively,but also brings them more spiritual enjoyment and improves residents’ happiness.Through the analysis of urban traffic travel process,the paper finds that traffic convenience is the main factor affecting urban travel behavior,and traffic convenience can be described from three dimensions of convenience,rapidity and economy,and the meaning of each dimension is defined in detail.Based on the theory of demand and derived demand,urban travel activities are divided into three categories: commuting,ordinary affairs and leisure.Taking the convenience of urban residents to travel as an opportunity,and using the GPS positioning data of Shanghai smart phone,this paper analyzes the factors affecting commuting travel activities,ordinary routine travel activities and leisure and entertainment travel activities from the macro level.It is found that the convenience of transfer,transfer distance,congestion,waiting time,walking time,in-car time,total travel distance,total travel time,travel cost and comfort loss are related to the types of travel activities.On this basis,the significant influencing factors of each type of travel activity are obtained by using multiple Logit models.According to the parameter calibration results and the significant influencing factors of each type of travel activity,a multi-objective path planning model with maximum generalized travel cost is established for each type of travel activity,and the model is constrained by conditions.Finally,part of the transportation network in Shanghai as an example,the design conforms to the artificial colony algorithm model characteristics,commuter travel,traditional transactional travel and leisure entertainment travel three activities have different optimal route scheme respectively,and each type of travel activity actual travel path and planning the optimal travel path difference is smaller.This paper aims to study the travel path planning scheme under different travel needs under the condition of traffic convenience,and provide convenient and personalized travel scheme for urban travelers,which helps to form a good travel environment and build a harmonious urban traffic environment.
