Embodiment Construction
[0020] see Figure 1 to Figure 5 Shown, the present invention is a kind of extraction method of taxi driving track experience knowledge path, comprises the following steps:
[0021] Step 10, using multiple taxis equipped with vehicle positioning systems to regularly collect data information during driving, and send the collected data information to the data service center;
[0022] Step 20. The data service center obtains the travel destination through direct interaction with the user, and mines the historical data information of the data service center according to the current departure location of the taxi, and obtains all taxis that have passed the departure location and destination after processing The driving track route and the time used constitute the information base P of the driving route information database;
[0023] Step 30: According to the departure time of the taxi, classify the driving route information database according to the date attribute and the meteorol...

The invention provides an extraction method of taxi driving track experience knowledge paths. The method comprises the following steps that: a large number of taxies in driving are utilized to regularly collect data information and transmit the data information to a data service center; 2, the data service center directly interacts with a user so as to obtain a travel destination, and digs historical data information according to a current departure position, and obtains a data set of driving track paths and used time of all taxies that pass the departure position and the destination after processing; 3, driving track information is classified according to date attributes and meteorological attributes based on departure time information so as to construct a driving track experience knowledge base, and the driving track information is checked respectively, and similar paths are screened; and 4, the data service center obtains a taxi track experience knowledge optimal driving path set through weighting calculation. According to the method of the invention, experiences of taxi drivers to choose driving paths by themselves are utilized to assist optimal path planning, and therefore, defects in path planning in the prior art can be eliminated, and reasonable path information services can be provided for the travel of the public.
Description
technical field [0001] The present invention relates to the application field of information technology, in particular to a method for extracting taxi driving trajectory experience knowledge path, so as to provide route planning service based on taxi driving experience knowledge for public trips and the like. Background technique [0002] When an existing taxi equipped with a navigation system is driving on the road, it can apply map matching, path estimation and other related calculation models and algorithms according to the vehicle position, direction and speed information regularly recorded by the vehicle-mounted global positioning system during its driving process. Processing is performed to correlate vehicle location data with urban roads in time and space. With the rapid growth of the economy, the number of motor vehicles is also increasing rapidly, and the problem of urban traffic congestion is becoming more and more serious. However, the optimal route selection in t...
