Abstract: In the plane signal intersection, the all red timing can reduce the collision between the phases in the intersection and improve the security. An appropriate all red timing can also improve the efficiency. Under the service level grading standard with delay as an indicator, the all red timing does not increase ｏｒ increase a service level, indicating that the impact of the all red timing on service levels is limited. However, in the con-flict analysis, the all red timing can greatly reduce the conflict, especially the crossing conflict, and improve the security level of the intersection. At the same time, the research also shows that many existing all red tim-ing algorithms are unreasonable.
