Abstract: How to design an intelligent pedestrian crossing system is an important in the field of urban traffic safety. This project analyzes the characteristics and problems in the current pedestrian crossing system. Based on the pedestrian crossing information collection method featuring pressure and laser sensors, it also improves the accuracy of data collection, and designs a system with the functions of regulating pedestrian crossing, pedestrian quantity collection, autonomous information transmission, and intelligent signal timing by adopting such technologies as single-chip microcomputer development, pedestrian crossing information collection, information transmission, information processing, and multi-source data fusion. The system consists of four main modules: pedestrian crossing waiting module, pedestrian information collection module, signal transmission module, and signal control module, which helps to realize intelligent timing according to the number of pedestrians and overcome the current defects of single data collection technology, large data error, low degree of system intelligence, and low utilization of the green light for pedestrians crossing the street. In addition, the system design module has the characteristics of low cost, strong practicability, and easy integration, and the research results have a bright application prospect.
Keywords: traffic engineering; pedestrian crossing; systematic design; data fusion; smart timing
