摘　　要：随着城市交通的发展不断提高,机动车与行人争夺道路时空资源而产生的冲突日益剧增,其中行人过街时带来的人车之间冲突最为突出的,且行人的主观意识、心理等存在差异,导致行人通过人行横道时有很大的随意性,违章而产生的不安全行为时有发生。针对这一交通现象本文提出一种以51单片机为主控制芯片,结合红外光电开关、语音模块及LED"光墙"模块构成的行人过街安全装置,该装置充分利用声光的双重提示,降低因行人闯红灯的违章行为带来的交通事故,保证行人和机动车在道路上安全的同时,也提高了道路通行能力。With the development of urban traffic,motor vehicles and pedestrians to increase resources for the road of time and space conflict,the conflict between pedestrian crossing from one car is most prominent,and the subjective consciousness,psychologicaldifferences of pedestrians,lead to a pedestrian crossing pedestrian has great randomness,illegal and unsafe behavior.For this traffic phenomenon is proposed in this paper is given priority to with 51 single chip microcomputer control chip,combined with electrical switch,a voice module and infrared LED "light wall" modules of pedestrian crossing safety device,the device makes full use of light and sound of dual tips,traffic accidents caused by pedestrians running red lights are reduced to ensure the safety of pedestrians and motor vehicles on the road and improve the capacity of the road.
