人行道被占用的影响分析

The Analysis of Pavement Occupied Effect

人行道的主要功能是满足步行交通的需要并且不影响路面车流的行驶.在人行道被占用且仍有可供行人通过的宽度时,行人通行的空间变小,行人的行走受到限制,速度降低,舒适度减小.当人行道完全被占用时,行人利用最外侧的车行道来绕过被占用的人行道路段,直接与车辆发生冲突,车辆的行驶对行人的安全构成威胁,使人产生恐惧感,行人的出行安全没有保证.人行道被完全占用时,行人占用车行道通行,使道路的通行能力降低,同时使车辆的行驶速度降低,行车延误增大.

The main function of the pavement is to carter the need of walk traffic while not to affect vehicle flow on the roads. When the pavement is occupied but some room still left for pedestrians to cross, the room for pedestrians to cross is becoming smaller, the walk of the pedestrians is restricted, the speed is becoming lower and the satisfaction for the pedestrians is reduced. When the pavement is totally occupied, pedestrians use the outboard lanes to make a detour round the occupied pavement. In this situation, pedestrians collide with vehicles and vehicles endanger the safety of pedestrians. They will form a sense of fear and their travel safety will not be guarantee. When the pavement is occupied absolutely, pedestrians occupy vehicle lanes. Thus the passing capacity of the road is reduced; the speed of vehicles becomes lower and the travel delay increases.
