Embodiment 1

[0067] The method for predicting road congestion based on taxi location of the present invention, the method steps are as follows:

[0068] S1. Constructing taxi road operation records; among them, constructing taxi road operation records is to receive the location information of taxis in real time by installing GPS positioning instruments on taxis (the current positioning technology can guarantee errors within 1m or more accurately), and obtain The geographical location information of the taxi forms the road operation route of the taxi, which is low in cost, high in efficiency, and reliable in real time.

[0069] S2, establish the statistical database of taxi vehicle running speed in different road sections at different times, including time data, road section data and running speed data in the database; the specific steps are as follows:

[0070] S201, according to the taxi road running record constructed in step S1, calculate the taxi running distance at different times thr...

Embodiment 2

[0106] The implementation process generally requires four parts of work processing:

Abstract

The invention discloses a method for predicting road congestion based on taxi positioning, and belongs to the field of transportation. The technical problem to be solved by the invention is how to usethe taxi congestion to provide traffic management departments with vehicle congestion in the future road section so as to more reasonably arrange personnel and optimize the transportation plan. The technical scheme adopted is that the method comprises the steps of S1, constructing a taxi road operation record; S2, establishing a statistical database of the running speed of taxis at different times and different sections; S3, establishing a classification prediction model, that is to establish a decision tree model based on the database; and S4, forecasting and testing: predicting the congestion of the road at a specific moment through the decision tree model by using the taxi running record of a certain section of the road for one week, comparing with the actual congestion situation in the future, and optimizing the decision tree model according to the actual congestion situation to meet the acceptance criteria.

Description

technical field [0001] The invention relates to the traffic field, in particular to a method for predicting road congestion based on taxi positioning. Background technique [0002] The current situation of road congestion is basically reported according to the current congestion situation of the road, and the road congestion situation expected at certain specific moments of the road is not predicted in advance. Drivers and others obtain driving routes mainly by judging the current road congestion situation by looking at the map app or listening to traffic broadcasts at the current moment, and it is difficult to change the current congestion situation. If you can know in advance the congestion situation of the road at a specific moment tomorrow, you can make more reasonable road travel choices and improve your travel experience. The current technology is mainly used to collect vehicle location information. The patent document CN104881999A discloses a distributed system and m...
