Method and device for automatically checking traffic limit information of electronic map

Abstract

The invention provides a method and a device for automatically checking traffic limit information of an electronic map. The method comprises the following steps of: acquiring trace data of a road where a vehicle runs within a predetermined time period by using a network; acquiring new traffic limit information of the road according to the trace data; and if the new traffic limit information is consistent with the original traffic limit information of the road, which is pre-stored in the electronic map, determining that the original traffic limit information is correct. By using the technologyprovided by the invention, workers are not required to be dispatched to a road site, and the trace data of vehicles running through the road can be monitored and recorded through the network, so a large number of human resources and material resources can be saved; moreover, according to a counted result instead of a single record as a detection standard, the counted result is compared with the pre-recorded original traffic limit information so as to avoid errors caused by traffic violation of the vehicles and other possible equipment faults.

Description

technical field [0001] The invention relates to electronic navigation technology, in particular to a method and device for automatically checking traffic restriction information on electronic maps. Background technique [0002] The navigation electronic map is a key component of the navigation system, and its accuracy directly affects the application level and service quality of the navigation system. Among them, the road traffic restriction information is an important element in the route calculation, and its accuracy is particularly important. [0003] In the traffic roads in the real world, each road is marked with traffic direction information, marking the road as one-way traffic or two-way traffic, and from one direction to another direction is allowed / prohibited, etc., such as figure 1 In the navigation electronic map shown, 0 means undetermined, and the default is two-way traffic, 1 means two-way traffic, 2 means one-way traffic, and 3 also means one-way traffic.
