HIStory

The original traffic system had only 2 cycles. They were only intended for straight movements.

However, the number of cycles became 4 due to the 2 cycles for turning movements.

Even if there are other cycles where straight and turning movements happen at the same time, the STOP time is still thrice the GO time.

The following suggested systems change the stop-go time ratio from 75:25 to 50:50. In other words, the STOP and GO time would be equal again! Each type of intersection has an appropriate traffic system:
- Continuously Flowing Intersection for wide intersections without infrastructures:

- Diverging Diamond Interchange for wide intersections with existing infrastructures:

- Cloverleaf Interchange for narrow intersections in village roads:

* The infrastructures refer to underpasses or overpasses, such as flyovers and tunnels.
