Problems solved by technology
However, the situation in the prior art is that since the fixed detectors are difficult to cover every intersection, there will be multiple sub-sections between the two fixed detectors, and the speed of each sub-section is different. The first two The prior art does not consider this situation
And the latter two prior art, although relate to the speed of the sub-section, but it is by evaluating the speed of each sub-section first, and then obtain the overall speed of the evaluation section from the speed of each sub-section, it does not use the data fusion algorithm, in the fixed detector When every intersection can be covered, the speed of each sub-section can be accurately calculated

The invention belongs to the field of information processing technology and solves the technical problem in the prior art of calculating speed assessment of sub-sections between bayonet pairs through data fusion. The technical solution of this application is based on the fixed detector data installed at the intersection and the floating vehicle road condition data, integrating the advantages of the two data in assessing traffic conditions, and at the same time, taking into account that there may be multiple sub-sections between the two fixed detectors Compared with the fusion from the speed level in the prior art, the present invention adopts the fusion method from the time dimension, so that the road conditions of each sub-section can be analyzed without the need to install fixed detectors in each sub-section. to evaluate.
Description
technical field [0001] The invention belongs to the technical field of information processing, and in particular relates to a traffic data processing system and method. Background technique [0002] With the continuous advancement of social urbanization, the number of motor vehicles in various cities in my country has been greatly increased. At the same time, with the improvement of people's living standards and the enhancement of consumption concepts, people's travel needs have also been greatly improved. The increasing demand for motor vehicles and travel poses new challenges to the maintenance of traffic road management and traffic road operation efficiency. Provide a solution. Among them, road condition detection and release play an important role. Real-time and reliable road condition information provides an important reference for travelers to optimize their travel routes and avoid congestion. It improves the travel experience of travelers while promoting the improvem...
