Example Embodiment

[0043] Example 1

[0044] The urban expressway ramp exit of the present invention and the adjacent intersection signal light linkage control system, see figure 2 As shown, the system includes a traffic flow detection unit installed at the exit ramp of an expressway, and the location of the traffic flow detection unit is shown in figure 1 As shown; the traffic flow detection unit is composed of a data processing board and eight detector boards connected to the data processing board bus. The hardware of the detector uses Altera Cyclone series FPGA EP1C6 as the processor. This implementation The traffic flow detection unit in the example uses a coil detector; the traffic flow detection unit set at the exit ramp of the expressway in this embodiment is used to detect the traffic flow at the exit ramp of the expressway to obtain the vehicle Traffic data.

[0045] The urban expressway ramp exit and the adjacent intersection signal light linkage control system is also provided with two s...

Abstract

The invention relates to a signal light linkage control system of an express way ramp outlet and an adjacent intersection in a city. The linkage control system is provided with a linkage control unit which is used for carrying out linkage controlling on an express way ramp outlet signal light at the connecting part of the express way outlet ramp and a side road as well as an intersection signal light arranged on the down stream of the express way outlet ramp adjacent to the express way outlet ramp according to the traffic flow data of the express outlet ramp, thus the traffic jam at the express way outlet ramp is effectively relieved. In addition, the linkage control system guarantees that the travelling of vehicles on the side road on the upper stream of the outlet ramp is not limited by the signal light through controlling the signal light on the side road on the upper stream of the outlet ramp under the condition that the outlet ramp has no traffic jams, thereby the traffic transportation capacity of the side road is effectively improved.

Description

Technical field [0001] The invention relates to the field of intelligent traffic control, in particular to a system that can perform linkage control on signal lights according to the traffic flow of an urban expressway exit ramp and adjacent intersections. Background technique [0002] The urban expressway is the main artery of the urban road network. It satisfies the sustainable development of the city with fast, connected, and large-capacity traffic functions. However, the problem of traffic congestion on expressways has become increasingly prominent in recent years, which has seriously affected the efficiency of urban expressways. . [0003] The above-mentioned expressway problem has a very obvious traffic situation, that is, during the traffic peak period, the traffic density of the main road is already quite high, so at the exit ramp of the main road expressway, there will be a large number of vehicles that need to go from the expressway. The road exits and enters the auxilia...
