中文摘要：

本文研究信号交叉口行人、自行车和电动车的间隙接受行为。通过拍摄录像获取相关数据,比较了不同交通方式的接受间隙,并用Logit回归建立了间隙接受模型。结果表明三者在近边的接受间隙都显著大于远边,三者之间的接受间隙无显著差异,但非机动车的违规率明显高于行人。主要原因是在有车冲突（有接受间隙）时三者的违规率无明显差异,而在无车冲突（无接受间隙）时非机动车的违规率显著高于行人。等待情况、可接受间隙值、间隙类型和冲突车辆的行为会显著影响间隙接受行为。本文的结果对理解违规群体的穿越行为及其建模有参考价值。

英文摘要：

This paper investigated the gap acceptance behavior of pedestrians and cyclists at signalized intersections.Data was collected by video cameras,the accepted gaps of three transport modes were compared and Logistic regression was applied to model the gap acceptance behavior.The results indicate that the accepted gap of each transport mode at near end is significantly larger than that at far end.There is no significant difference among the accepted gaps of three modes;while cyclists have higher rates of red-light infringement than pedestrians.This main reason is that cyclists are more likely to violate the traffic lights than pedestrians in the situation without conflicting vehicles,although this is no significant difference of the violation rates in the situation with conflicting vehicles.The waiting status,acceptable gaps,gap type and the movement of conflicting vehicles are proved to have significant influence on gap acceptance behavior.These results in the paper are meaningful to understand and model the crossing behavior of violators at intersections.
