Response time: if it is desired to reduce the time needed for traffic surveillance and control system 130 provides output result, then handling Engine 220 selects that the method for result can be provided within the shortest time in all available information processing methods, without examining Consider other selection factors.With reference to the matrix of Fig. 3, handles engine selection and refer in the column of the leftmost side one and the matrix element of highest a line The processing method shown, because data volume to be processed increases (for example, with single position is handled with moving down in matrix 305 The method in third row matrix set is compared, and the processing method in the 4th row matrix needs to handle entire track, and so on), It just needs more to handle the time to which system provides output result.In addition in this case, response time and information processing Association between method can be generated in configuration phase by system manager.

Export the type of result: if only including in accident or traffic congestion by the output provided by traffic surveillance and control system In the case of the alarm that issues, then the information processing method of the knowledge using the identifier using PLMN cell, such as method a3 It is sufficient and (in order to determine in the blocking of a certain regional traffic and issue corresponding alarm, is located at using only mobile terminal The algorithm of the information of Hong Qu or cell is sufficient；Track knowledge can provide higher accuracy, but sometimes extra). If being changed to intentionally get the related instruction of vehicle flow on entire road network, it is preferred that using the rail for using mobile terminal The processing method of mark knowledge, such as processing method a6.In general, system manager is responsible for establishing output class and processing ready for use Association between method.

Export the intended recipient of result: if output result is intended to service to driver with information, using not It is especially accurate, but the quick processing method of response time is sufficient；If output result is changed to be intended to by public administration Department is used for the medium-term and long-term plans of some region of public transportation, then processing engine 220 preferably selects accurately, even if relatively slow Processing method.

For the price for the service payment that traffic surveillance and control system provides: according to the accuracy of output result, handling the time, need The quantity for the input data wanted, can be to every kind of processing method apportioning cost；Handling engine 220 can also be according to traffic surveillance and control system 130 subscriber agrees to that the price of payment selects processing method.

Any other selection criteria can also be replaced, information processing method ready for use is arbitrarily selected by system manager.

It is worth noting that the invention is not limited to any specific cost functions that system manager uses.For example, It, can be according to method a1 imparting value 1, to method c1 imparting value 2, Xiang Fang in the case where cost function indicates the accuracy of output Method a2 imparting value 3 etc., until the mode design cost function to method c6 imparting value 12.
