Embodiment Construction

[0063] The present invention will be further described below in conjunction with the accompanying drawings:

[0064] When the server performs matching processing, based on the real-time information input by the user and the map information on the server, according to the geographical relationship between the boarding point pairs, and considering the detour distance and time constraints, the multi-level optimization screening process is used to ensure automatic Take the best of matching combinations.

[0065] The electronic map used in this system must contain at least the following road segment attribute information: road segment number, road segment name, left and right end node coordinates, road segment length, road segment speed, and road segment type. And address data information: address number, address name, address coordinate information corresponding to it and the type of the address. The coordinates of the address can be obtained from the address name.

Abstract

The invention relates to a ridesharing dynamic matching multi-grade screening method, which pertains to the field of intelligent transport dynamic ridesharing automatic matching system. The system takes internet or a mobile wireless network as an information interaction platform; registered drivers and hitchers send enquiry requests and provide corresponding information to a server which provides hitching information services; the server dynamically constructs a hitching information network, loads data performs grading matching treatment, and finally sends hitching combined matching results and hitching paths back to enquirers. The server carries out the three-grade matching treatment according to the following steps: 1) performing grade one selection according to time and bypass constraints; 2) performing grade two selection according to the principle of proximity; 3) performing grade three selection according to users' preferences. The system can rapidly match the hitching parties, so as to obtain hitching matching combination which meets the conditions and the recommended hitching path for the users to choose. The system can effectively improve ridesharing efficiency and reduce the urban traffic jams.

Description

technical field [0001] The invention relates to a dynamic matching multi-level screening method for carpooling, which can be used for carpooling drivers according to user information such as time, geographic location, etc., under the condition that the constraints such as detour and boarding time are satisfied, and based on the multi-level screening technology Dynamic matching with hitchhikers. The invention belongs to the field of intelligent traffic dynamic carpooling automatic matching system. Background technique [0002] Carpooling means that several people travel together in one car, especially for long-term commuting to and from get off work. Carpooling is already very common in many countries and is encouraged and supported by the government. Carpooling not only saves money for users, but also helps reduce traffic congestion, save energy and reduce environmental pollution. Some countries have opened up a special high passenger load rate for carpool travelers, name...
