利用摄像机观察记录的6个交叉口总量600个行人在通过信号交叉口时的行为特征数据,分析了影响行人行为的影响因素,利用Logit模型对信号交叉口行人过街遵章率建立了预测模型,并对结果进行了合理性分析。结果显示,当没有护栏或者没有完整护栏的情况下,绕行距离比越大,行人使用过街设施的比例就越低,当有完整护栏设施的情况下,遵章率和绕行距离比关系不大;当没有护栏或者没有完整护栏的情况下,交通干扰越大,行人使用行人过街设施过街的比例就越高,当有完整护栏时,交通干扰对遵章率影响不大;当没有护栏或者没有完整护栏的情况下,路侧干扰越大,行人使用过街设施通过交叉口的比例就越低,当有完整护栏的情况下,路侧干扰对行人遵章率的影响不大。因此完整且适当的护栏设置可以有效地提高行人过街的安全性。结论为交叉口安全性改造措施的有效性提供了理论上的支持。
Using the camera to observe and record the total number of 6 intersections recorded by the pedestrian at the signalized intersection, the influencing factors of the pedestrian behavior were analyzed. The Logit model was used to establish the prediction model of pedestrian crossing compliance at the signalized intersection , And the results of a reasonable analysis. The results show that when there is no guardrail or no complete guardrail, the greater the detour ratio, the lower the proportion of pedestrians using over-street facilities. In the case of complete guardrail facilities, the relationship between compliance rate and detour ratio is not When there is no guardrail or there is no complete guardrail, the more traffic disturbance, the higher the proportion of pedestrians crossing the street with pedestrian facilities. When there is a complete guardrail, traffic interference has little effect on the compliance rate; when there is no guardrail or Without full guardrail, the greater the roadside disturbance is, the lower the proportion of pedestrian crossing facilities passing through the intersection is. When there is a complete guardrail, the influence of roadside disturbance has little effect on the compliance rate of pedestrians. Therefore, complete and appropriate fence settings can effectively improve the safety of pedestrian crossing. The conclusion provides theoretical support for the effectiveness of safety improvement measures at intersections.
