Problems solved by technology

Since congestion is a differentiated phenomenon, the customer who is blocked at the 100th place on the same road section may have completely different effects from the customer at the front. Therefore, it is impossible to simply compare the carrying capacity of the path with the estimated number of vehicles. taking into account this difference
At the same time, in the above-mentioned patent documents, the method of estimating the estimated amount of vehicles on the road is to collect the current position and target position of the floating car and then perform full path prediction. Due to the change of real-time path traffic conditions, when the path For a long time, it is easy to accumulate errors and reduce the accuracy

Embodiment Construction

[0046] First, combine figure 1The congestion prediction method will be described. After the data collection step collects relevant information including initial location information and target location information of the vehicle, the information planning path collected by the path planning step according to the data collection step; The node is divided, and the node is a separation point; then the time group by which the vehicle passes through the corresponding node is calculated by the time group calculation step, and the time group through the node is to predict the time when the vehicle passes through the above-mentioned node according to the established data model Set, the above-mentioned so-called vehicle data model refers to the displacement-velocity model supported by the big data background, which can be an average speed model, or it can include factors such as waiting time for red street lights, driving habits of vehicles, speed limit, etc. The displacement-velocity ...

Abstract

The invention discloses a congestion pre-judging and traveling route planning method as well as a traveling route planning system. The congestion pre-judging method is based on a concept of sequencing transportation means; and the traveling route planning method and the traveling route planning system are formed in conjunction with the congestion pre-judging method on the basis of automatically dividing the traveling route. By adopting the method and the system, the problem that the precision is lowered due to error accumulation can be effectively avoided.

Description

technical field [0001] The invention relates to a method for predicting congestion and planning a driving path based on vehicle information and a system for planning a driving path. Background technique [0002] The existing navigation methods generally can only simply give the path from the starting location to the target location, but cannot give the traffic conditions along the way, let alone effectively predict the possible congestion. [0003] A prediction technique for traffic congestion is described in Patent Document 1 below. [0004] Patent document 1: Chinese invention patent CN 103366563. [0005] In the above-mentioned patent documents, the prediction of the traffic congestion situation is to compare the load capacity of the road with the estimated presence of vehicles on the road. Since congestion is a differentiated phenomenon, the customer who is blocked at the 100th place on the same road section may have completely different effects from the customer at th...
