Title:
EXPRESSWAY ROAD CONDITION MONITORING METHOD AND APPARATUS BASED ON TOLL COLLECTION DATA
Document Type and Number:
WIPO Patent Application WO/2022/143549
Kind Code:
A1
Abstract:
An expressway road condition monitoring method and apparatus based on toll collection data, and a computer device and a storage medium, which relate to the technical field of big data. The monitoring method comprises: determining whether the current traveling vehicle reaches a target point within an estimated arrival time point; and if it is determined that the current traveling vehicle reaches the target point within the estimated arrival time point, detecting that the current traveling vehicle is not stuck on a target traveling path, otherwise, detecting that the current traveling vehicle is stuck on a road section which is within the target traveling path and is associated with at least one target point (S104). A road network topological graph for expressway toll collection is introduced, such that it can not only be accurately detected whether congestion occurs on a target traveling path, but a road section which is specifically within the target traveling path and is associated with a specific target point and on which the congestion occurs can also be detected.
