In the present invention, four sections sections A 1 at the parting of the ways, the sections B 2, the sections C 3 or the sections D 4 road surface on bury
If 25 groups of press belts 5 being mutually parallel, 4-6 meters of distance between adjacent two press belts 5.The vehicle commander of general automobile is 5 meters of left sides
The right side, therefore can judge road surface by the pressure sensor of multigroup press belt 5 blocks situation.
Such as in four sections sections A 1, the sections B 2, the sections C 3 or the sections D 4, one of section (sections D 4) is direct current
When with turning left current, other three sections (sections A 1, the sections B 2, the sections C 3) are red light phase, at this time the sections A 1, the roads B
Press belt in section 2, the sections C 3 is started to work under the control of main PLC controller 11；
The sections A 1, the sections B 2, the pressure sensor on the press belt on the sections C 3, have vehicle distance hair by the road surface in this section
To main PLC controller 11, main PLC controller 11 is judged stagnant in the sections A 1, the sections B 2, the sections C 3 by comparison arithmetic element
Longest section is blocked up, then blocks longest point by main PLC controller 11 to control in the sections A 1, the sections B 2, the sections C 3 again
Class PLC controller (branch PLC controller A, branch PLC controller B or branch PLC controller C) leads to lamp A, straight to start straight trip
Lamp C is led in the logical lamp B of row or straight trip, to maximize the resource of rational proportion crossroad, is handed over to alleviate alleviation city automobile
Logical congestion.
A kind of method for alleviating city vehicle traffic congestion of the present invention, it is using the logical of the crossroad in city
Time delayed signal lamp is installed under row signal lamp, several pressure inductors are installed in four current sections, to judge the passage section automobile
Amount；It has easy for installation, simple operation, preferential to alleviate automobile amount pressure most by increase delay transit time convenient for repacking
The traffic in big section ensure that the passage pressure of road so that the passage rate in four sections is balanced, and it is stifled to alleviate traffic
Plug.
