Detailed description of the invention
Actual life is seen, although there being some passengers to have some path after forming path of riding to be coincidence path, and the destination not problem on same path by bus, solve the method that the interchangeable many taxis of this problem change share-car.Below in conjunction with better embodiment therein, the present invention program is described in detail.
As it is shown in figure 1, the method in the present embodiment includes step:
S101: obtain the first passenger's origin information and endpoint information of the first taxi, generation first path by bus；Obtain origin information and endpoint information generation second path by bus of the second passenger；According to the first by bus path computing coincidence path by bus, path and second.
As in figure 2 it is shown, the first passenger takes the first taxi (acquiescence knows origin information) at place O, and endpoint information D is informed cabdriver.Now, by first passenger's client (mobile phone) or the mobile phone of cabdriver or other communicating terminals, starting point O and endpoint information D of the first passenger can be uploaded to server, server obtains the content of database, empirically value generation first path by bus.As preferred example, server also can be according to jam situation generation first path by bus of highway at that time.Generally speaking, passenger can consider various factors taking taxi when, wherein time factor and price factor are major consideration, the present embodiment mainly considers time factor, the method in its generation first path by bus, determine the beginning and end of the first passenger, select the front M bar driving path that origin-to-destination distance is nearest;Each bar driving path in described M bar driving path is divided into some segment paths, calculate the taxi average speed through every segment path respectively, calculate taxi average time through every segment path respectively further according to the length in every segment path, the average time in every segment path is added and obtains the running time that each bar driving path is total;The relatively running time of each bar driving path, using the shortest for running time one as the fastest driving path (i.e. elect as first by bus path).When taxi carries after the first passenger sets out, on the way constantly receive origin information and the endpoint information of N number of second passenger around, and generate the N number of corresponding second path by bus according to these information.Assume the starting point of now the second passenger be A terminal be C；First then calculated path by bus is AB with the path that overlaps in the second path by bus.
Additionally, each path of riding can be the preset path of storage in database, the empirical data that can recall from database after passenger inputs the information of beginning and end, the impact of typically no consideration environmental factor at that time, if consideration environmental factor, the fastest driving path in S101 can be used.Server generates the first path and other paths of riding by bus the most in real time also according to the jam situation of highway at that time.
S102: obtain origin information and the endpoint information of the 3rd passenger of the second taxi, generates the 3rd path；
After the first taxi carries the first passenger and the second passenger sets out, on the way receive origin information and the endpoint information of the 3rd passenger of the second taxi of surrounding, and according to these information generation the 3rd path by bus.Assume the starting point of now the 3rd passenger be O ' terminal be E；Then the 3rd by bus path be that O ' E(is shown in Fig. 2).
S103: if there is intersection point in described 3rd path with the described path that overlaps, and the endpoint information of the first passenger is in the 3rd path, sends and changes share-car prompting.
As in figure 2 it is shown, the first passenger is from place O, its terminal is D.And now the 3rd path AB that overlaps that by bus path O ' E with S101 is formed has an intersection point G, and the terminal D of the first passenger is also at the 3rd path O ' E by bus, and system can send to individual passengers and driver changes share-car prompting.If individual passengers and driver agree to change share-car, then the first passenger will get off and then the second taxi at intersection point G so that individual passengers successfully can be delivered to destination on the basis of not taking a roundabout way by taxi.Comparing existing share-car, this method will be greatly enhanced the resource utilization after share-car.
As the optional example of another one, system, also according to endpoint information generation the 4th path by bus of described intersection point G and the first passenger, if the endpoint information of the 3rd passenger is in the described 4th by bus path, sends and changes share-car prompting.As it is shown on figure 3, the first passenger is from intersection point G, its terminal is D ', then the 4th of its generation path by bus is O D '.And now the 3rd terminal E by bus is in the 4th, path is O D ' by bus, system can send to individual passengers and driver changes share-car prompting.
As an example that can launch, if having the 4th passenger at the second taxi, and the endpoint information of the 4th passenger is in second by bus path, sends and changes share-car prompting.This time, two taxis respectively have exchanged a passenger so that they can arrive the destination of oneself after once transfer.
In the mode of foregoing description, the mode changing share-car needs the agreement of individual passengers, but also wants them to forbid going back on one's word, if passenger or driver can be made to suffer unnecessary loss because going back on one's word after once agreeing to.
Fig. 4 shows the structural representation of a kind of taxi Carpooling system embodiment of the present invention.
