Embodiment Construction
[0042] In the embodiment of the present invention, there is no need to manually collect traffic restriction information on site, but the traffic restriction information is automatically determined by processing the track point information of multiple floating vehicles. Information is updated in a timely manner. Specifically, when it is necessary to determine the time limit for entering the second road from the first road, according to the position information and time point information of the floating car in the acquired track point information, determine the time limit for entering the second road from the first road. The time point when each floating car in the floating car of the driving track enters the second road from the first road, and then according to the time point when the floating car enters the second road from the first road, it is determined to enter the second road from the first road. The restricted hours of the road.

The invention discloses a method and a device for determining traffic restriction information, which is used for solving a problem that a manual acquisition mode in the prior art generally needs to consume a lot of manpower and is low in acquisition efficiency so as to be difficult to ensure timely update of the traffic restriction information. The method comprises the steps of acquiring track point information of a plurality of floating vehicles, wherein each piece of track point information comprises position information and time point information of the floating vehicle; determining floating vehicles having a traveling track driving from a first road to a second road according to the position information in the track point information of the plurality of floating vehicles; in allusion to each determined floating vehicle, determining a time point when the floating vehicle drives from the first road to the second road according to the time point information in the track point information of the floating vehicle; and determining a traffic restriction time period for driving from the first road to the second road according to the determined time point when the floating vehicle drives from the first road to the second road.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to a method and device for determining traffic restriction information. Background technique [0002] Intelligent Transportation System (Intelligent Transportation System, ITS) is the development direction of the future transportation system. It is an accurate and efficient comprehensive transportation system established by effectively integrating advanced information technology, electronic sensor technology and computer technology. management system. ITS can make effective use of existing traffic facilities, ensure traffic safety, and improve transport efficiency. Therefore, it is increasingly valued by various countries. [0003] Traffic road network data, as one of the important elements of ITS, is the basis for traffic analysis research, planning and design. In order to ensure the current situation of traffic road network data, the traffic department needs to update the ro...
