Embodiment Construction

[0036] The present invention will be further described in detail below.

[0037] The system of the variable speed limit sign and road change management and control measures of the present invention includes an on-site online APP, a client, a communication system, a control center, an information demander and a variable speed limit sign, and the control center is electrically connected with a communication interface.

[0038] The on-site online APP and the client have an editing function, which is used by the on-site manager to select and modify the target variable speed limit sign information and the management and control measures of the road section according to the actual situation, and send the preset results to the control center through the communication interface. review.

[0039] The control center is used to receive the information of the on-site online APP and send it to the client to prompt the operator to review, evaluate and review according to the management and ...

Abstract

The invention relates to a road variable speed limit sign and a method for changing the speed value of the road, in particular to a system and a judging method for the variable speed limit sign and road change management and control measures. It includes on-site online APP, client, communication system, control center, information demander and variable speed limit sign, the control center sets the communication interface and communication protocol. The method of system update and release is that the manager first revise the target variable speed limit sign speed or the information of road section management and control through the on-site online APP according to the actual situation of the current road section, and send the revised information to the control center for review and review. The result is sent to the variable speed limit sign and information requester. Using the system and the judgment method, the speed limit information and control measures can be changed and released in real time according to the actual situation of the current road, which consumes less manpower and can avoid the problem of inaccurate path planning for drivers and unmanned vehicles (travelers). .

Description

technical field [0001] The invention relates to a system and a judging method for releasing speed limit values ​​of variable speed limit signs and road control information, in particular to a system and judging method for variable speed limit signs and road change control measures. Especially suitable for unmanned path planning. Background technique [0002] A variable speed limit sign is a traffic sign that can update the speed limit threshold value according to weather and traffic conditions. The variable speed limit value is a target variable speed limit sign, road section or location set by on-site personnel or managers according to traffic management and safety needs. Appropriate speed, suitable for road sections that require real-time updates of road control measures. When the on-site personnel need to control and control the target road section, such as traffic restriction and prohibition, they also need to release and update the map or navigation information in real...
