There will be three kinds of collision avoidance operations when a driver encounters an object just ahead: braking and stopping before collision, steering the vehicle for avoidance, and steering and braking simultaneously. In any case, a certain crash-unavoidable zone exists to each vehicle. A 'cross-point determined by the vehicle behavior is a key factor in designing a crash-unavoidable zone and depends mainly on vehicle speed, friction between the wheels and the road, and the steering angle. In this paper, this zone is determined by taking these factors into account. For head-on and rear-end collisions, the evasive paths taken by vehicles are simulated taking the drivers evasive action into account and unavoidable collision zones and cross points for such collisions are determined. A monitor zone could be established and a technique for collision risk assessment based on the presence or absence of obstacles in this zone are studied. Also, with regard to collision occurring at intersections, a collision danger zone by means of virtual sensing has been determined and its efficiency is confirmed in a simulation. This results should prove to be very useful for advanced automotive technology developed in the future.
