Problems solved by technology

[0006] When implementing the technical solution of the present invention, the inventor found that the prior art road condition information filling method has at least the following problems: although the daily speed variation trend is roughly similar, there is a certain delay in the morning and evening peaks of daily road traffic congestion. Mean method, there will be a large error, and the filled data is not accurate enough

Embodiment 1

[0060]An embodiment of the present invention provides a method for filling traffic road condition information, such as figure 1 As shown, the method includes:

[0061] Step S101, according to the historical traffic data, complete the vacant data in the traffic traffic data;

[0062] Step S102, according to the road condition change trend obtained by clustering all the traffic condition data of the same road in the same time period, establish a road traffic condition trend pattern library;

[0063] Step S103: Match the road condition trend of the road at the time point t with the road condition change trend of the road in the road traffic trend pattern database, and calculate the road at the time point t as the driving speed for filling the road condition.

[0064] The embodiment of the present invention also provides a traffic road condition information filling system, such as figure 2 As shown, the system includes: a historical data preprocessing unit 1 , a road condition ...

Embodiment 2

[0074] On the basis of Embodiment 1, further, this embodiment of the present invention provides a method for filling traffic road condition information, such as image 3 As shown, the method includes:

[0075] S201. Read at least three months of historical traffic data;

[0076] The historical data preprocessing module is based on the accumulated historical traffic data of the city for more than 3 months, and fills in the vacant road conditions at each time point on each road, that is, reads the historical traffic conditions of the floating car city for n (n≥3) months data.

[0077] Further, the statistical time period is divided according to the time point of the road condition.

[0078] Among them, the choice of roads includes the main roads of the city, such as the collection of all road units of the main road in Beijing, such as: Zhichun Road, Xueyuan Road, etc.; the value of the time point includes every 5 minutes from 00:00-23:59 as the boundary Time period, such as: ...

Abstract

The invention discloses a traffic road condition information filling method and a system, which relate to the field of traffic information treatment and can improve the accuracy of filling road condition information. The traffic road condition information filling method comprises the following steps: completing vacant data in traffic road condition data according to the historical road condition data; carrying out clustering treatment on all the road condition data of a same road in the same time period for obtaining the road condition change trend, and establishing a road traffic road condition trend mode library; matching the road condition trend of the road in the time period containing the time point t with the road condition change trend of the road in the traffic road condition trend mode library, and calculating the driving speed of the road at the time point t for filling the road condition. The method and the system are applied in the treatment of traffic accident information of an intelligent traffic system.

Description

technical field [0001] The invention relates to the field of traffic information processing, in particular to a method and system for filling traffic road condition information. Background technique [0002] Advanced Traffic Information System (ATIS for short) is based on a complete information network, through sensors and transmission equipment equipped on roads, vehicles, transfer stations, parking lots and meteorological centers, to obtain All kinds of real-time traffic information are processed comprehensively, and comprehensive, accurate and real-time road traffic information is provided to the society in real time. [0003] Traffic travelers can determine travel modes and select routes based on this information, and drivers can also dynamically select driving routes through automatic positioning and navigation systems. The advanced traffic information service system not only provides timely and accurate traffic information for traffic managers, enables the traffic man...
