Samenvatting
This paper proposes the enhancement of the following driver's response by the use on motor vehicles of a stoplight which positively meets certain theoretically derived requisites. These include first, the instantaneous degree of deceleration of the lead vehicle regardless of vehicle separation; second, the stationary on-road or off-road position of the lead vehicle., thereby signaling the possibility of dangerous high closure velocities. In addition, the stoplight must be compatible with the nervous system; capable of attracting the attention of the following driver and congruous with existing signal systems.
