摘要：AbstractThe existence of dilemma zone is the main reason for accidents and violation of traffic laws near signal intersections. Firstly, the concepts of the yellow interval dilemma and the reasons why there exists the yellow interval dilemma are introduced in this paper. Then, the existing solutions of the yellow dilemma problem are introduced and their drawbacks are also analyzed. The previous researches are mainly based on simulation and there is not much study on the actual system design. The design of a Dynamic Speed Guidance System under CVIS is developed, which is of vital significance in reality.
