In general, traffic signal phase setting method can be divided into the following kinds:

The first: simple 2 phase

When the intersection is an equal weight and less traffic intersection, turn left and less traffic situation, can be set.

The second: simple 3 phase

Set up a dedicated left lane, as a main branch of transportation under the condition of less, can be increased on the main road again left alone signal phase, this intersection usually can use a simple three phase control.

The third: simple 4 phase

When the traffic flow on the intersection of main and branch is larger, and in the main and branch set up separate left lane, intersection signal control can be set to simple 4 phase.

Fourth: complex phase

Complex 8 phase need to optimize the induction detection under the condition of green light phase.
