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 invention provides a route planning device. The device comprises an information acquisition module, a road segment recognition module, an experience route extraction module, an experience route storage module, a route repairing module, a route verifying module and a route planning module, wherein the information acquisition module is used for acquiring floating car information periodically, each piece of floating car information comprises the logo, position, acquisition time and manned state information of a floating car, and the manned state information can be manned information or unmanned information; the road segment recognition module determines the road segment where the floating car is located according to the position in each piece of floating car information and correlates the determined road segment with each piece of floating car information; the experience route extraction module determines an experience route according to acquired information, and the experience route storage module stores the experience route in an experience route library; the route repairing module is used for repairing two discontinuous road segments in the experience route to enable all the road segments in the experience route to be continuous; the route verifying module is used for deleting repeated road segments, invalid road segments and encircling road segments in the experience route; the route planning module is used for planning the route for a user according to the experience route library.

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...
