abstract="Two intersection safety applications are described. The two applications are  based on video cameras mounted on pillars in road intersections, and computers that run artificial vision algorithms to track the movement of vehicles around the intersection. According to the position and speed of the incoming cars, the system calculates the collision risk. The first application is designed for non-signalized intersections. If high risk of accident is concluded by the system, the system electronically highlights the existing warning signs stationed at the secondary entrance to the intersection. We claim that this action can raise the arousal of drivers and reduces the risk of side-front accidents. The second application is designed for signalized intersections. When  a driver enters the intersection during the change interval in a way that might  create a dangerous situation in the conflict zone, the system delays the green light to the other traffic, thus prolonging the inter-green time.<p />",
