The invention discloses a traffic safety research method based on pedestrian traffic behaviors, and the method comprises the steps: 1, enabling an information collection unit to collect pedestrian traffic accident data and the pedestrian traffic flow, and transmitting the data and the flow to a decision-making unit, and enabling the decision-making unit to screen the information, remove useless information, and reserve reliable information with a large reference value; step 2, in a decision-making unit, utilizing the collected pedestrian traffic accident data and the pedestrian traffic flow data obtained by investigation, and utilizing a chi-square goodness of fit test method and a dominance ratio model to research the influence of the pedestrian facing the traffic flow compared with the pedestrian backing on the traffic flow on the pedestrian safety; besides, based on the pedestrian traffic accident data and the pedestrian traffic flow data, researching the safety of pedestrians when crossing the street at intersections of urban roads and highways, road zebra crossings and road sections without zebra crossings by using a variance analysis method, and finally, proposing suggestions for improving the pedestrian traffic safety according to safety analysis results of the pedestrians under different traffic behaviors.
本发明基于行人交通行为的交通安全研究方法,其中,步骤1:信息采集单元对驾行人交通事故数据和行人交通流量进行采集并发送到决策单元,决策单元对信息进行筛选,去除无用的信息,保留可靠且参考价值较大的信息;步骤2:在决策单元中,利用已经收集的行人交通事故数据,以及调研得到的行人交通流量数据,利用卡方拟合优度检验方法和优势比模型研究行人面对交通流相比于背对交通流对行人安全性的影响;另外,基于行人交通事故数据和行人交通流量数据,利用方差分析方法研究行人在城市道路和公路的交叉口、路段斑马线和路段无斑马线处过街时的安全性,最后根据行人在不同交通行为下安全性分析结果,提出提高行人交通安全的建议。
