The invention provides a route planning method and system based on traffic road data. The method includes the steps that travel starting point and terminal point information and a time range are obtained; preset time intervals are set within the travel time range; according to the travel starting point and terminal point information, travel routes are planned, current and historic traffic road data of all the travel routes are obtained, current and historic jamming indexes of all the travel routers are calculated, whether the travel routed meeting a first preset condition exist are judged, and if yes, current time serves travel time, wherein the first preset condition is that when the difference value between the current jamming indexes and the historic jamming indexes exceeds a preset threshold value, the travel routes meeting a second preset condition are selected from the travel routes meeting the first preset condition serve as preferential travel routes, and the second preset condition is that the current jamming indexes are minimum, or the difference value between the current jamming indexes and the historic jamming indexes larger than the current jamming indexes is the maximum in the travel routes meeting the first preset condition. Travel is facilitated for a user, and the user experience is effectively improved.
Description
technical field [0001] The invention relates to the field of computer software, in particular to a route planning method and system based on traffic road data. Background technique [0002] With the continuous development of traffic navigation technology, route planning and intelligent travel have gradually gained people's general favor. At present, after planning various feasible travel routes, navigation products often calculate the approximate time of each travel route based on the historical traffic data of each travel route, and then provide users with choices. [0003] However, with the continuous improvement of urban road construction, road conditions may change at any time. Only considering historical traffic data obviously cannot accurately reflect the road conditions and provide users with the best travel route and travel time. Contents of the invention [0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is...
