Example Embodiment

[0059] Example one

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

[0061] Step S101: According to the historical road condition data, fill in the missing data in the traffic road condition data;

[0062] Step S102: Establish a road traffic trend pattern library based on the road condition change trend obtained by clustering all road condition data on the same road in the same time period;

[0063] Step S103: Match the road condition trend of the road in the time period at the time point t with the road condition change trend of the road in the road traffic road condition trend pattern library, and calculate the road at the time point t as a driving speed to fill the road condition.

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

Example Embodiment

[0073] Example two

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

[0075] S201. Read historical road condition data for at least three months;

[0076] The historical data preprocessing module is based on the accumulated historical traffic data of the city for more than 3 months, and calculates the filling of the vacant traffic conditions at each time point on the 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 road selection 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 the boundary from 00:00-23:59 every 5 minutes Time p...

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...
