The intersection environment considered in this paper.
It is a widely-seen crossroad with three incoming and outgoing lanes in each direction.

Flowchart of the proposed IM strategy.
The work of checking table is done on the IM side while the heavy computing work is done on the vehicle side shown in the dashed box.

Comparison of average time delay using the three traffic control strategies under different traffic densities.
The horizontal axis is the time interval of generating vehicles at the starting point of the road. A small value corresponds to a heavy traffic situation. The line labeled T represents the traditional traffic light, A for adaptive light, and I for the proposed intelligent strategy.
