Method and device for recommending planned routes

Abstract

The invention discloses a method and device for recommending planned routes. The method includes the following steps that: a route calculation instruction is received, an initial route area is determined; first time to arrive at intersections in the initial route area is calculated, and at least one original recommendation route is determined according to restriction rules corresponding to the intersections; the current position of a terminal is obtained, intersections that the original recommendation routes do not pass are determined; and the consistency of second time to arrive at the intersections that the original recommendation routes do not pass and the first time is judged, and whether at least one alternative recommendation route is to be calculated is determined. According to themethod and device for recommending the planned routes of the invention, the planned routes are calculated effectively on the basis of the make full use of the traffic restriction information of roads,so that more accurate planned routes can be provided for users, and behaviors such as violating traffic regulations and detouring caused by navigation guidance errors can be effectively avoided.

Description

technical field [0001] The invention relates to a method and device for recommending planned routes. Background technique [0002] In the existing car navigation, the route planning function considers the factors such as road restrictions and traffic lights. The general method is to create a time zone for the user based on the current time at the beginning of the route calculation. When the time regulation is in Within this time zone, the route will avoid this road section, but the time zone obtained from this is general and the accuracy is poor, so it is easy to cause the user to drive to this road section at an unregulated time point, and the route calculation process However, it avoids driving on this section of the road, causing the user to take the wrong driving route or detour; and during the driving process of the self-vehicle, due to many factors that will affect the driving speed, it may also cause the arrival time of the self-vehicle to change, or The previous reg...

[0002] In the existing car navigation, the route planning function considers the factors such as road restrictions and traffic lights. The general method is to create a time zone for the user based on the current time at the beginning of the route calculation. When the time regulation is in Within this time zone, the route will avoid this road section, but the time zone obtained from this is general and the accuracy is poor, so it is easy to cause the user to drive to this road section at an unregulated time point, and the route calculation process However, it avoids driving on this section of the road, causing the user to take the wrong driving route or detour; and during the driving process of the self-vehicle, due to many factors that will affect the driving speed, it may also cause the arrival time of the self-vehicle to change, or The previous regulatory information is invalid, causing the user to take an extra section of the road or a restricted road section; for example, a U-turn is prohibited after 17:00 at a certain intersection. After using the above method to plan the route, the time zone is not after 17:00. Route planning U-turn at this intersection, but due to road conditions, or delays in the middle, when the user drives to this intersection after 17:00, the user follows the original planned route prompts to make a U-turn, thus violating traffic regulations and may be punished accordingly
