<P>PROBLEM TO BE SOLVED: To solve the problem that a braking spot at the time of a yellow signal and the proper spot of a crossing with attention are difficult to discriminate at a place near an intersection. <P>SOLUTION: There are two cases of the case of tires capable of displaying performances on a dried road surface, on which cars apply normal brakes, and the case of the states of the worn tires on the road surface under the state in which the road surface is subject to the effect of a rain in the case when the yellow of the signal is lit under the state in which the cars drive at speeds close to a speed limit towards the intersection with the signal. Lines displaying final spots where the cars placed at free-running distances + brake stopping distances = stopping distances must apply the normal brakes by an inverse calculation from the stopping distance at the intersection in both cases are drawn so as to cross a road. <P>COPYRIGHT: (C)2007,JPO&INPIT |
