Embodiment Construction

[0043] Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail, so that those skilled in the art can implement accordingly with reference to the description:

[0044] In order to achieve the above purpose, the present invention proposes a vehicle trajectory reconstruction method based on bayonet data, the steps of which are as follows figure 1 As shown, the specific steps are as follows:

[0045] Step 1, set up the initial road network.

[0046] Select the range of the initial road network according to the actual road network. After selecting the range of the initial road network, it is necessary to mark the nodes of the initial road network. The nodes are all selected as survey points that can obtain checkpoint data, and the adjacent nodes are directly connected, that is, the adjacent nodes are reachable at one time. After all the nodes are determined, mark all the nodes. The mark can be marked by the bayonet devi...

Abstract

The invention discloses a gate data-based vehicle trajectory reconstruction method. The method includes the following steps that: step 1, an initial road network is set; step 2, an alternative trajectory set is set; step 3, trajectory decision-making attributes are set; and step 4, an optimal alternative trajectory is calculated. With the method adopted, vehicle trajectories can be reconstructed based on gate data when vehicle trajectory points are missing and vehicle trajectories are incomplete in the gate data.

Description

technical field [0001] The invention relates to the field of transportation, in particular to a vehicle track reconstruction method based on bayonet data. Background technique [0002] The bayonet data is a series of vehicle record data measured by the bayonet equipment installed at the intersection, including license plate number information, vehicle passing time information, location information, etc. At present, more and more researches are using checkpoint data, including road status assessment, commuting characteristic analysis, etc. However, due to the limited accuracy of the license plate number recognition by bayonet equipment, vehicle track points are often missing during data processing, resulting in incomplete tracks and affecting subsequent analysis. At present, there are many researches on vehicle trajectory reconstruction, the patent application number is 201310156627.1 - "A Driving Trajectory Restoration Algorithm Based on Road Attributes and Real-time Road C...
