The following questions should be noted in the phase coordination of road traffic lights:

Determine the release mode:

In road lamp for scientific and reasonable phase timing, release methods to combine road lane distribution, for example, when the intersection in each direction less import lanes, lane cannot satisfy turn left and go straight direction vehicles waiting for signal needs, can be considered by the import release in turn.

2, traffic to traffic:

Do not agree to consider intersection traffic flow, asymmetry, etc., reasonable allocation adjustment phase time, such as the asymmetry of left turn traffic, but at the same time release to change to the left after a certain time, interrupted traffic flow smaller left traffic instructions, traffic continues to release, and can also release the imported straight vehicles.

Road traffic:

Should fully consider crossing the road traffic flow situation, in general, traffic flow of road green passage of time is relatively long, the road green passage of traffic flow is small is shorter, so that we can avoid a backlog of road vehicles more effectively, and the other road green for a long time is no vehicles through cases.

4, traffic flow changes at intersections:

In the general case, road traffic signal cycle time is not set in stone, in different periods, the same day in different times, traffic flow of intersection is different, therefore, in road traffic signal timing phase, in addition to match the length according to the intersection traffic flow changes to make the corresponding adjustment.
