Embodiment Construction

[0052] In order to more clearly and accurately illustrate the present invention's method for judging the road section traffic state, the calculation method of the present invention, etc. will be introduced below in conjunction with specific examples. The examples described below do not represent all the examples of the present invention, so examples based on the theory of the present invention without making innovative achievements all belong to the protection scope of the present invention.

[0053] This example uses the checkpoint data of Bengbu City to illustrate the present invention, and intends to judge the traffic status of the downstream section of Gongnong Road. First of all, it is necessary to extract and record the historical checkpoint data of the Donghai Avenue section, perform a series of analysis and calculation on the historical data, and use the clustering algorithm to calculate the parameters calculated from the historical data to obtain the parameters of each...

Abstract

The invention discloses a road section traffic state discrimination method based on checkpoint data. The road section traffic state discrimination method is characterized by comprising the steps of: step 1, performing data preprocessing; step 2, calculating road section historical basic parameters; step 3, calculating a road section smooth-passing rate and a road section load margin at each moment; step 4, rating traffic state grades; step 5, extracting the road section load margin M and the road section smooth-passing rate O in current data; step 6, and judging traffic state grades. The adopted road section traffic state discrimination method disclosed by the invention processes and analyzes the checkpoint data, reflects traffic state information by adopting the two parameters of road section load margin and the road section smooth-passing rate, finally calculates to obtain a membership degree of the current traffic state to each traffic state of the road section, can express the roadsection traffic state information more precisely, and has better reference significance.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a checkpoint-based method for judging the traffic state of a road section. Background technique [0002] The traffic status of the road section can reflect the traffic condition of the road, and an appropriate method for judging the traffic status of the road section can obtain the traffic status information of the road section in real time and accurately to ensure that the road is safe and smooth. Traffic management personnel can also implement corresponding management and control measures through road traffic status information to improve road traffic efficiency and reduce congestion. With the rapid development of urbanization, the number of motor vehicles is increasing day by day, so it is becoming more and more important for the task of judging urban road traffic status and alleviating road congestion. [0003] The evaluation of urban road traffic status is mainly d...
