A crossroad can be controlled by four traffic lights which has two roads both ways having green while two roads have red. This system is used for temporary or semi-permanent traffic control and will operate 24/7 if required. TechRoad can also supply light towers and vms boards if required.
A T Intersection can be controlled by three traffic lights which usually have the main road both ways having green which would change to red giving green for the single entry road. If this is a low volume traffic road a sensor can be installed which will only operate when a vehicle is present. If required each road of the T can operate as a green light and the other two red lights. In this set up 2 sensors can be installed. We can supply Light Towers and VMS boards if required.
