| 摘 要： | 为了对新建城区交叉口行人-机动车分相位临界条件进行定量分析,运用行人-机动车阻滞机理和抢行博弈模型等相关理论,得到了完整的阻滞时间计算模型;结合右转车辆与行人等饱和度时平均延误最小的思想,对信号周期内机动车与行人的分相位设置临界状态建立数学模型,提出了新建城区交叉口行人-机动车分相位安全评价方法。结果表明:行人-右转机动车冲突是新建城区交叉口冲突的主要形式,根据分相位量化条件可将危险交叉口细分为分设临界交叉口和时时监控交叉口。

| Abstract: | In order to quantitatively analyze the critical condition of sub-phase for motor vehicles and pedestrians in the intersections of new urban zones,using the theory of game model and the block mechanism for motor vehicles and pedestrians,authors got the complete calculated model for retardant time of pedestrians.Based on the principle that average delay is the smallest,when the saturations of pedestrians and right-turn motor vehicles are equal,the safety evaluating method and the math model of sub-phase setti... |
