However, this method requires a large amount of information on historical traffic events. The traffic events that occurred on the same road link in a period of time in history cannot contain all types of traffic events that will occur in the future. The established road traffic condition trend model library exists limitation

Embodiment Construction
[0014] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0015] The embodiment of the present invention aims at the shortcomings of the current event link judgment and data filling method, according to the spatio-temporal change law of the upstream and downstream link traffic flow when a traffic event occurs, determine the specific traffic event link, and fill in the missing data link, Improve the release system of the intelligent traffic information system to provide travelers with complete road condition information, thereby reducing the negative impact of traffic incidents on road conditions.
[0016] figure 1 The flow chart of the traffic event road link detection and data filling method provided by the embodiment of the present invention includes the following steps:
[0017] Step 101. Obtain the affected road lin...

The invention discloses a traffic incident road chain detecting and data filing method, and pertains to the technical field of intelligent transportation. The method comprises the following steps: acquiring an influenced road chain described by traffic incident test information, and acquiring upstream and downstream extended road chains of the influenced road chain; acquiring the road condition information of the first M sampling periods of the influenced road chain and the upstream and downstream extended road chains by taking the sampling periods to which a traffic incident belongs as the benchmark, wherein M is greater than 1; determining the road chain to which the traffic incident belongs according to the road condition information; and filling the road condition information of a data missing road chain according to the road condition information. According to the invention, for disadvantages of the current incident road chain judging and data filing method, according to spatio-temporal variation rules of upstream and downstream road chain traffic flows when the traffic incident occurs, a specific traffic incident road chain is determined, and filling is performed on the data missing road chain, so a release system of an intelligent transportation information system is perfected to provide complete road condition information for travelers, so that negative influences of the traffic incident on road conditions can be reduced.
Description
technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a traffic event road link detection and data filling method. Background technique [0002] With the development of society and economy, traffic congestion and pollution have become major problems facing urban development. Due to the limited space for urban development, many cities adopt intelligent transportation technology to provide road condition information to drivers through various methods, provide reference for their travel, and choose travel routes reasonably, so as to achieve the purpose of alleviating congestion, saving energy and reducing emissions. [0003] At present, many cities have established a taxi-based floating car information collection system. This system uses positioning technology, wireless communication technology and information processing technology to realize the GPS location information and driving direction of taxis driving on the ...
