Background
With the expansion of city scale and the increase of the holding quantity of motor vehicles, the problems of traffic pollution, traffic jam, parking space shortage and the like almost become common problems of each city. Although private cars and taxis have a great specific gravity in urban traffic due to their flexible and convenient travel, they are also "culprit" which causes the traffic problems described above. Compared with private cars and taxis, the bus has the advantages of large traffic volume and low freight price, effectively saves road resources, reduces traffic pollution, has fixed route and poor flexibility, has the bypassing problem for passengers, has low punctual rate, crowded carriage and long transfer waiting time, and reduces the traveling experience of the passengers.
Under the economic background of sharing, the windward vehicle can utilize the existing traffic infrastructure, so that not only is the flexibility of traveling of private cars and taxis reserved, but also the utilization efficiency of the vehicles and roads can be improved, the traveling cost is reduced, and the defects of the traffic mode are overcome. According to the urban commute study report in 2018, the daily commute mileage of Beijing, shanghai, chongqing and Tianjin residents are 13.2km,12.4km,12.2km and 9.9km respectively, and the commute time is 56 minutes, 54 minutes and 48 minutes respectively. In terms of commute mode, people mainly choose public transportation and private car commute. From the above data, it is clear that in the aspect of mid-long distance travel, only taking commuter travel as an example, the windward traveling potential in the city is huge.
However, the current windward traveling requires a higher overlap ratio of traveling paths of both parties participating in traveling, most of the traveling paths are disposable carpools without taking transfer into consideration, and the traveling paths are static, so that the matching degree and flexibility of the windward traveling are greatly reduced, and the participation degree of vehicle owners and passengers is inhibited. Therefore, the design and introduction of the dynamic transfer system and the method for the windward traveling can improve the supply and demand matching probability and the flexibility of the windward traveling, dig the market potential of the windward traveling, improve the vehicle utilization rate, reduce the traffic pollution and have huge social and environmental benefits.
At present, different realization methods are provided for windward traveling according to various patents. A windward passenger recommendation method and device is proposed in patent CN201810206545.6, and a windward passenger recommendation method based on big data is proposed in patent CN 201811201845.1. However, there are few patents directed to systems and methods for windward dynamic transfer.
Disclosure of Invention
The purpose of the application is that: aiming at the problems that most windward traveling in the prior art is one-time carpooling without taking transfer into consideration, thereby reducing the vehicle utilization rate and increasing traffic load, the windward dynamic transfer system is provided.
The technical scheme adopted by the application for solving the technical problems is as follows:
the beneficial effects of the application are as follows:
the application improves the success rate of supply matching between windward passengers and vehicle owners, and exploits the potential of windward traveling. Compared with the traditional bus, the windward line with transfer is flexible, and the windward meeting the conditions can be customized according to the travel characteristics of passengers; compared with taxis, passengers can pay relatively lower fees and the cost is lower. As a form of 'customized public transportation' between buses and taxis and private buses, the system has strong feasibility when the windward permeability in the system is high, reduces traffic burden and improves vehicle utilization rate.
