Problems solved by technology
[0004] The problem that exists in the above prior art is, on the main line of expressway and national and provincial highway, for the upstream and downstream section of toll station, the reason of passive parking may be traffic congestion, also may be caused by traffic facility, and prior art directly All passive parking situations, including toll booth parking, are considered to be traffic jams, which makes the upstream and downstream traffic information of toll booths inaccurate

Embodiment Construction
[0059] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0060] In the prior art, when the floating car is used to study the road condition information of the upstream and downstream sections of the toll station, all passive parking situations, including parking at the toll station, are directly considered as traffic jams, thus making the upstream and downstream road condition information of the toll station inaccurate.
[0061] One of the core concepts of this application is to establish the speed range of the upstream and downstream intervals of the toll station through the samples of each toll station. If the speed range of the downstream section is determined, it is judged that the upstream and downstream traffic information of the toll station is normal tr...

The invention provides a method and device for judging upstream and downstream traffic information of a toll station. The method includes: a time window is selected aiming at each toll station, global positioning system (GPS) points of vehicles passing through upstream and downstream of the toll station in the time window is extracted to be used as samples, and no traffic jam or traffic accident occurs at the upstream and the downstream of the toll station in the time window in the time window; an upstream and downstream space speed range of the toll station is determined on the basis of sample information and map information; whether GPS point information of vehicles driving through the upstream and the downstream of the toll station in a pre-installed period conforms to the upstream and downstream space speed range is judged; if on yes judgment, the toll station upstream and downstream traffic information is labeled as normal traffic; and if on no judgment, the toll station upstream and downstream traffic information is labeled as traffic jam. The method and device for judging the upstream and downstream traffic information of the toll station can improve accuracy of the toll station upstream and downstream traffic information.
Description
technical field [0001] The present application relates to the field of processing and application of road traffic condition information, in particular to a method for judging upstream and downstream road condition information of toll stations, and a device for judging upstream and downstream road condition information of toll stations. Background technique [0002] Floating car technology is to select a certain number of vehicles in the traffic flow, and obtain the position, speed, azimuth and other information of the vehicles through the GPS devices installed on these vehicles, and then obtain the operation status of the traffic flow. Floating vehicle technology is an important way to obtain information on traffic conditions and is an important field of intelligent transportation. [0003] At present, the research on the use of floating car GPS data to obtain road condition information simply divides parking types into active parking and passive parking. The condition of ac...
