FIG. 1 is a flow chart of the system structure provided by the present invention;
wherein: 1. a flow detection device; 2. a traffic light; 3. a control server; 4. overhead flow control induction screen.
Detailed Description
A traffic flow control system for an elevated ramp comprises a plurality of flow detection devices 1 distributed on an elevated main road, traffic lights 2 arranged at the entrances of the ramps, and a control server 3 for controlling the traffic lights 2 according to signals detected by the flow detection devices 1, wherein the flow detection devices 1 and the traffic lights 2 are connected with the control server 3. The utility model discloses a set up flow detection equipment 1 cooperation on the overhead main road and set up the signal lamp in the entry on the ramp and reached the volume of effectively controlling the ramp vehicle and afflux, guarantee that the main road traffic is normal, prevent to flow in the purpose that blocks up because of the too much main road traffic that leads to of ramp vehicle of afflux under the great prerequisite of main road traffic.
The flow control system of the elevated ramp vehicle also comprises an elevated flow control induction screen 4 arranged at the lower entrance of the ramp and the ground road, and the elevated flow control induction screen 4 is connected with the control server 3.
The flow control system of the elevated ramp vehicle also comprises at least one ramp flow detection device arranged on the elevated ramp, and the ramp flow detection device is connected with the control server 3.
The flow detection device 1 is at least one of a microwave detector, a high-definition camera, a photoelectric sensor and a ground induction coil.
The ramp flow detection device is at least one of a microwave detector, a high-definition camera, a photoelectric sensor and a ground induction coil.
The flow control system of the elevated ramp vehicles enables the vehicles on the main line of the express way to pass preferentially, ensures the safety and smoothness of the main line, avoids the influence of overlong queuing of the entrance ramp on the normal operation of the ground road as much as possible, maximizes the passing benefit of the express way and the associated road, and issues an induction strategy in advance on the entrance ramp to guide the vehicles to select other paths.
Aiming at a plurality of ramp control intersections, a camera or other sensor equipment of a corresponding section on an elevated road transmits road vehicle saturation rate information of the section to a respective traffic control server 3, meanwhile, flow information is transmitted to ramp intersections on the upstream and downstream, the control server 3 decides the time length of a traffic light 2 of a ramp traffic light 2 by calculating and processing received upstream and downstream information and acquiring the flow information by self, meanwhile, a flow collector on the ramp also transmits the flow information to the traffic control server 3, and the control server 3 simultaneously transmits induced information to a corresponding elevated flow control induction screen 4.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
