Embodiment Construction

[0033] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention is not limited to the examples.

[0034] Such as figure 1 Shown is a schematic diagram of the system architecture of the path planning system of the present invention. The system includes a path planning device 10 , a plurality of floating vehicles 20 wirelessly connected with the path planning device 10 and a terminal 30 . In this embodiment, the route planning device 10 is a server, and the terminal may be a mobile terminal, such as a mobile phone, or a computer. The floating car is a taxi. The route planning device 10 obtains traffic information from the floating vehicle 20 through a wireless network, and the terminal 30 can access the route planning device 10 to obtain a target route.

[0035] Such as figure 2 As shown, the path planning device 10 includes an information collection module 101 , a road sect...

Abstract

The present invention provides a path planning device, comprising: an information collection module that periodically collects floating car information, and each of the floating car information includes the identification, location, collection time, and passenger information of the floating car. The information includes manned and unmanned; the road section identification module determines the road section where the floating car is located according to the position in the information of each floating car, and associates the determined road section with the information of each floating car; the experience path extraction module, Determine the experience path according to the collected information; the experience path storage module stores the experience path in the experience path library; the path repair module is used to repair two discontinuous road sections in the experience path, so that the experience path The road sections in are all continuous road sections; the path verification module is used to delete repeated road sections or invalid road sections, or surrounding road sections in the empirical path; the path planning module uses the empirical path library to plan paths for users.

Description

technical field [0001] The invention relates to the technical field of traffic planning, in particular to a path planning device and method. Background technique [0002] Travel route planning is one of the core parts of traffic information system, and traffic information system plays an important role in supporting and guiding traffic decision-making. Under the influence of a scientific and reasonable information system, through the interaction between traffic decision-making and the overall road network of the city and closely matching the actual conditions of people, vehicles, and roads, the efficiency of traffic transportation can be effectively improved, traffic congestion can be alleviated, and the traffic capacity and capacity of the road network can be improved. road speed. [0003] The existing path planning is an algorithm based on the urban road network to find the shortest path and the shortest time path. Some scholars study the shortest path with turning delays...
