Abstract

The invention provides a traffic trajectory extraction method and device based on e-police data. Preprocessed point location data and e-police data of e-police equipment is obtained, travel paths of a vehicle are extracted according to the preprocessed point location data and e-police data of the e-police equipment, the travel paths of the vehicle are classified according to the driving speed of the vehicle and travel time of the travel paths, and a traffic trajectory of the vehicle is determined according to the classified travel paths of the vehicle. According to embodiments of the invention, the traffic trajectory of the vehicle is extracted on the basis of the point location data and e-police data of the e-police equipment, a data source is single, the amount of sample is large, and a traffic trajectory extraction method is simplified. The travel paths of the vehicle are classified after being extracted, different traffic trajectory determining methods are used for different types of travel paths, the obtained traffic trajectory satisfies a practical travel scene more, and the traffic trajectory extracting precision is improved.

Description

Technical field [0001] The embodiments of the present invention relate to the field of traffic technology, and in particular to a method and device for extracting traffic travel trajectories based on electric police data. Background technique [0002] With the application of various advanced transportation tools and various information-based traffic management methods, transportation infrastructure and traffic operation modes are changing rapidly. In this case, the traditional method of obtaining residents’ characteristic data through the traditional resident travel survey cannot meet the needs of transportation planning and management in the new era, no matter in terms of economy, accuracy of results, and timeliness. With the continuous development of big data technology, the traffic data around us has gradually shown an explosive growth trend. How to simply and effectively use traffic big data to replace traditional survey methods to analyze traffic travel trajectories has beco...
