Problems solved by technology

[0004] At present, taxis are equipped with positioning system (Beidou or GPS) data, and the research on monitoring vehicle driving behavior based on vehicle positioning data (GPS) mostly focuses on the monitoring of bad driving behavior, such as the "GPS-Based Bad Driving Behavior Monitoring Method and System - Application for Publication”; Luo Zanwen invented “a real-time evaluation method of vehicle driving behavior based on Beidou or GPS data”, which mainly uses GPS data to analyze sudden acceleration, sudden braking, sharp turns, speeding, driving, etc. Driving behaviors such as driving at night and fatigue driving; the overall analysis of GPS trajectory data is less, and the monitoring of illegal parking of taxis is hardly involved

Abstract

In order to monitor dangerous driving behaviors such as particular and common frequent parking, illegal parking and the like of taxies, make up for the monitoring of taxi parking behaviors in areas without monitoring, and guarantee the traffic safety, the invention provides a taxi illegal parking monitoring and early warning method based on GPS trajectory data and map data. The method comprises the following steps of data processing, matching of the trajectory data and a digital map, loading and unloading passenger parking point interpretation and illegal parking interpretation and early warning, comparing parking point clusters read out by sampling data with an illegal parking range in map information and POI information, and always monitoring whether a taxi is illegally parking. The taxiillegal parking monitoring and early warning method based on the GPS trajectory data and the map data provided by the invention promotes the fusion application of the trajectory data, POI data and road data, expands the direction of information mining and ensures the traffic safety.

Description

technical field [0001] The present invention relates to the field of traffic safety, in particular to a method and system for monitoring illegal parking and driving behavior of taxis based on trajectory data, POI (Point of Interest) data, map data and other multi-source data. Background technique [0002] Taxi is an important type of urban motor vehicles, and it is also a business card of a city. However, taxi drivers must pay attention to potential customers when driving, and meet the needs of passengers to get on and off at will. It is easy to induce driving behaviors such as illegal parking, which is harmful to urban roads. The organization of traffic flow, as well as urban traffic safety has caused a great negative impact. Frequent parking and illegal parking in taxis are almost unique and common characteristics of taxis. [0003] At present, the monitoring research on illegal parking of vehicles is mostly focused on adding monitoring instruments for monitoring, which c...
