Abstract:

Improving the traffic safety in intersections can solve the conflict ofdifferent traffic streams, can ensure traffic safety and freely flow, improvethe passes ability of intersections, through improving the condition of readand traffic control. It is important to review the factors which affectedtraffic safety of intersections, and to study the improvement design on trafficsafety, including the channellization, pedestrian safety, traffic control etc,and illuminating the feasibility with examples.

Key words:

intersection; safety; conflict; channellization
