Embodiment Construction
[0014] A fast location method for traffic violation accidents based on PGIS, see figure 1 , figure 2 : It is aimed at the association of road spatial geographic information in the traffic management information system and the collection of electronic coordinates of traffic violations and accident locations; on the basis of the PGIS platform, through the two-dimensional table of the spatial geographic database, a comprehensive application platform road code library and spatial geographic information is established. Database road information mapping relationship; for urban roads, the intersection of roads is used as the base point, supplemented by direction and relative displacement, and spatial calculation is used to realize the rapid positioning of illegal accident points; The rapid positioning of illegal accident points is realized by spatial calculation based on direction, absolute kilometers and meters.
[0015] It includes PGIS-based road space geographic information ...

The invention provides a PGIS-based method for quickly locating traffic violation accident locations, which realizes the PGIS-based rapid location of violation accident locations and the collection of electronic coordinates when collecting road traffic violation and accident information. It is characterized in that it is aimed at the association of road spatial geographic information in the traffic management information system and the collection of electronic coordinates of traffic violations and accident locations; on the basis of the PGIS platform, the comprehensive application platform road code library is established through the two-dimensional table of the spatial geographic database The mapping relationship with the road information of the spatial geographic database; it includes the setting of road spatial geographic information based on PGIS and the rapid positioning of traffic violation accidents based on PGIS.
Description
technical field [0001] The invention relates to an integrated application technical field of a national public security traffic management information system and a police geographic information system (PGIS), specifically a PGIS-based method for quickly locating traffic violation accident locations. Background technique [0002] At present, the national traffic management information system has established a public security traffic management comprehensive application platform (hereinafter referred to as the comprehensive application platform) through the reconstruction of the system platform, database and software architecture, which further enhances the sharing and reuse of public security traffic management business information, and greatly improves The application level of traffic management information system has been improved. As an important part of the comprehensive application platform, the road traffic violation and accident handling system has achieved nationwide ...
