Centralized Harmonization Traffic Signal Controller

Traffic crossing signal controllers are basic facility of urban traffic signal 

control. Intelligent traffic crossing signal controller is developed according 

to characteristics of urban traffic flow. It can not only form single-pot self-

adjustable signal control system, but also form main line adjustable signal 

control system and promote adjustable signal control in a large area.

Main features:

1.Modularization: Mechanical structure, electronic hardware and software 

realize modularization.

2.Flexibility: Various control programs are applied flexibly, such as flash 

control, periodic control, manual control, various time control, sense 

control, online control and so on.

3.Reliability: It can operate descending automatically with good supervisory 

function and self error-correcting ability. 

4.Safety: Multilevel green-conflict protection.It can detect automatically 

green-conflict and yellow-flash circuit periodically to maker sure the safety.

5.Intelligence: Study function, auto-adjust control calculation approach, 

optimal error-bearing function. 

6.Openness: Open software data interface, able suitable for user unit to 

expand according to their desires and realize every control calculation 

program.

7.Interactivity: large-screen LCD with Chinese multi-level menus, making 

operation simple and convenient with good man-machine communication.

8.Maintainability: complete self-detecting function, simple and easy 

maintenance.

Main control models and electrical features:

1.Yellow flash program: fixed periodical program, various fixed periodical 

program.

2.Semi-sense (the lack of the installed detector or pickup camera in the 

intersection) 

3.control program.

4.Whole sense (enough of the detector or pickup camera in the intersection)

control program.

5.Max passing capacity program.

6.Adjustable green wave program.

7.Intelligent predictive control program based on the data of neighbor road or

key crossing.

8.Error-bearing control program when the camera or detector doesn?t work

Intelligent control program based on history data.

9.Intelligent control program for abnormal traffic flow or events.

10.Power:220VAC±20% 50/60Hz±2Hz

11.Power consumption: <50VA(not including the consumption of signal and 

peripheral equipment).

12.Working temperature: -40~+80

13.Relative humidity:40~90%

14.Insulation resistance: >10

15.Insulation and pressure resistance: 1250VAC one minute.
