Abstract:
In order to improve the roadside-signs recognition accuracy of car driver steering along the inboard driveway of multilane freeway, the setting problem of freeway side traffic signs was studied with probability theory. The mathematical model and algorithm for the problem of the side traffic signs being blocked off by large vehicles are set up. The individual approaches and methods of setting side traffic signs in sequence are brought out, i.e., to determine the location of side signs, to calculate the length of shelter rectangle, to calculate the shelter probability, to choose the number of side signs being set in sequence and to determine the minimal space between them. The computation results show that the probability of the driver being kept out of signs decreases exponentially with the increase of side signs being set in sequence. The established models and methods for setting side traffic signs in sequence are simple and feasible. It can solve the rational setting problem of side traffic signs in the freeway with multiple-lane.
