Abstract

The invention provides a real-time road condition and route planning method and equipment; the real-time road condition and route planning method comprises the steps that: if the sum of the received weighted road condition change values of all road sections in a pre-set surrounding area of a current position in current position information is judged and known to be more than a preset threshold value, a route is planned, so that the best route information is generated; and wherein, each weighted road condition change value is the multiplication of a road condition change value and a weighted coefficient. The real-time road condition and route planning equipment comprises a planning module, and is used for planning the route if the sum of the received weighted road condition change values of all road sections in the pre-set surrounding area of the current position in the current position information is judged and known to be more than the preset threshold value, so that the best route information is generated. The real-time road condition and route planning method and equipment reduce the planning quantity of the route planning equipment, avoid unnecessary planning, and improve the route planning efficiency of an intelligent traffic system.

Description

technical field [0001] The present invention relates to intelligent transportation technology, in particular to a real-time road condition route planning method and device. Background technique [0002] With the development of the Global Positioning System (G1obal Positioning System, hereinafter referred to as GPS) technology, the GPS navigation system is more and more widely used in life. The GPS navigation system can provide the user with a driving route to guide the user's driving. [0003] Since there are usually multiple driving routes between the starting point and the destination point, the road conditions on each route are also different. The intelligent transportation system developed based on GPS technology can plan the driving route in real time according to the road condition information, and provide users with an optimal driving route. However, with the increase of users, the amount of route planning of the intelligent transportation system also increases grea...
