Background

Currently, for toll-by-weight vehicles (e.g., trucks), detection of the vehicle at the exit of the highway (i.e., exit check-down) is required.

It should be noted that, in the above embodiment, the prompt information is used to instruct the target vehicle to exit the highway exit by driving to the target lane, so that the passing efficiency of the vehicle at the highway exit can be improved by the above embodiment.

The target weighing information comprises the total weight of the vehicle and at least one of vehicle type information, axle weight, axle number, axle type and other information of the vehicle.

The above-mentioned embodiments can be applied to the scenario shown in fig. 2, as shown in fig. 2, a weighing Unit is installed on a passing Road (i.e. a traffic lane) to form weighing areas on the traffic lane, and a Road Side Unit (RSU) and an image detection Unit, a contour detection Unit corresponding to each traffic lane are installed on a gantry near each weighing area.

Alternatively, the roadside unit, the image detection unit, the contour detection unit, and the weighing unit in the above embodiments may be installed in a main line (for example, a traffic road in the above embodiments) and/or a ramp before an exit of an expressway.

It should be noted that, in the above embodiment, the target vehicle information includes a license plate number of the target vehicle, and may further include vehicle type information and axle type information (for example, axle number or axle type information in other classification manners) of the target vehicle, and the first vehicle information may be the license plate number of the target vehicle. The contour information includes length information, width information, and height information of the target vehicle.

In the above embodiment, when the distance between the first position and the second position indicated by the second vehicle position information is within a preset distance range, it may be determined that the second vehicle position information is the position information of the target vehicle.
