Construction And Application Of Driver-passenger Guidance Model For Expressway New Type Service Area

With the improvement of economic level and service area construction requirements,the expressway new type service area came into being.In the service areas,the demand for driver-passenger is more urgent,the stay time of driver-passenger is shorter,the flow of pedestrian and vehicle are more frequent,and the interference between people and vehicles is more serious;compared with the traditional service area,the new type service area has diversified service facilities,large scale and high passenger flow.The above features will lead to both subjective and objective difficulties for driver-passenger in the new type service area to find their way in the complex building and find parking spaces in the parking lot.Therefore,comprehensively considering the characteristics of driver-passenger demand and vehicle operation and service facilities in the new type service area,the two interrelated models that the pedestrian route choice model and the optimal parking space choice model,that is,the driver-passenger guidance model are established,and the application method framework of the driver-passenger guidance model for expressway new type service area is proposed,which lays a theoretical foundation for the research of driver-passenger guidance system for the expressway new type service area.A travel distance perception experiment that can regulate the area of personal space in the walking environment is designed,and the free-flow walking speed of driver-passenger when they have four demand goals of toilet,catering,shopping and leisure is collected,and then the impact of pedestrian congestion on the perception of travel distance and the impact of the urgency of driver-passenger demand in the new type service area on the sense of congestion are comprehensively quantified in the form of the actual travel distance penalty function with congestion expansion coefficient.Next,the pedestrian route choice model with the perceived travel distance function as the path cost function is constructed,and then the parameter is calibrated with a real example.The result shows that compared with the model based on the actual travel distance,the model in this paper can more accurately explain the route choice intention of driver-passenger in the new type service area.The effects that the model in this paper used for pedestrian guidance can improve the equilibrium of passenger flow and the overall traffic efficiency of passenger flow are verified by the passenger flow simulation.The length of the shortest parking path is taken as the parking distance;the pedestrian route choice model is used to calculate the perceived travel distance indoors after parking;the driver-passenger crosswalk-choice behavior for crossing the road is analyzed under the five layout forms of the crosswalk in the service area,and then the calculation method of their walking distance outside after parking is put forward;considering the phenomenon that driver-passenger in the same car cross the road in groups,a method for calculating the average arrival rate of people crossing the road in groups is proposed based on the parking time in the service area,and the size of pedestrian group is determined according to passenger capacity of vehicles in service area,and then the critical gap that vehicle can cross is calculated from the perspective of pedestrian crossing safety,finally,the calculation model of parking delay is established based on gap acceptance theory.Considering the influence of parking driving distance,parking delay caused by pedestrian crossing,walking distance outside after parking,perceived travel distance indoors after parking on parking space choice,the optimal parking space choice model based on AHP-TOPSIS is established.The Yihezhuang service area of Jingxiong expressway is taken as a calculation example,and then the effects that the model in this paper used for parking space guidance can take into account the simplicity and patency of parking and convenience of parking space and promote the balanced utilization of parking spaces and reduce the interference between people and vehicles are verified by comparing the model in this paper with the model without considering the parking delay caused by pedestrian crossing.The conditions of driving the driver-passenger guidance system with the driverpassenger guidance model are analyzed from the data and operation level;the application environment of the model is established based on the five-dimension digital twin model;the logic flow framework of model application is established in three links that are model operation,operation optimization and data cleaning;in order to effectively run the logic flow,taking data acquisition equipment,information release equipment and network equipment as carriers,the physical framework of model application is established;the supporting technologies for running the logic flow are summarized from four aspects that are data collection,data transmission,platform construction and information release,and then the technology framework of model application is established.
