(2) and the real-time route planning and docking is realized through a domestic POI geographic data platform.
The prior technical scheme has the following defects:
(1) the access frequency to the three-party interface is too high, the cost is huge, and the data volume is continuously increased, so that the availability of local data is gradually reduced;
(2) the direct butt joint of the three-party real-time interface is suitable for the scene with low utilization rate, and is not suitable for the scene with high utilization rate (such as a time-sharing lease service scene of an automobile).

Optionally, the traffic information includes vehicle speed and congestion level.
Wherein, the traffic information is marked by the coordinate points, such as: the congestion conditions and the vehicle speed conditions of two groups of coordinate points of [ A1, B1], [ A2, B2] are respectively 65 km/h and 60 km/h which are unblocked, the data volume is very large and redundant if the data is stored locally based on the coordinate points, the road condition information is updated based on grids corresponding to the local Geohash codes, the access pressure and the access cost of a data updating interface (the delay of a three-party interface and most of the interfaces are charging interfaces) can be reduced to the greatest extent, the size of the grids is properly adjusted, the road condition information is updated, the data can be obtained more reasonably and timely, and the local path planning is more convenient.
According to the road condition information updating method provided by the embodiment of the invention, the coordinate points corresponding to the Geohash codes in the first Geohash code set are calculated by obtaining the first Geohash code set of the local path planning data, the coordinate point set is generated, the Geohash codes of the planned paths among the parking network points are obtained according to the first Geohash code set, the second Geohash code set is generated, the road condition information of the planned paths among the parking network points is obtained according to the set updating frequency and the second Geohash code set, the consumed time among the parking network points is calculated according to the mileage and road condition information of the planned paths among the parking network points, the number of times of accessing the three-party interface is reduced to a certain extent, the interface calling cost is reduced, and the travel expense can be locally estimated.
