Abstract: With the plane signal intersections as research objects, the change of main transportation operating parameters such as traffic capacity, delay and the number of stops before and after setting comprehensive waiting area at import channel under different saturation conditions was quantitatively analyzed. Combined with the setting rules of pre-signal control in comprehensive waiting area, two different pre-signal setting programs and calculation formulas coordinating with different phase sequences of main signal were given. Taking the actual survey data of Beijing Road-Linyu Road in Kunming as an example, VISSIM microscopic traffic simulation software was used to verify the evaluation results, which proved the validity of the theoretical analysis results. The research shows that: for the plane intersections of main roads in city under the oversaturated condition, setting comprehensive waiting area can effectively improve the traffic capacity and reduce the average delay, which significantly improves the traffic operation benefit of the intersection. However, unreasonable coordination program will bring negative impacts to the improvement of the comprehensive waiting area.

摘要： 以平面信号交叉口为 研究对象，对不同饱和度条件下进口道设置综合待行区前后的通行能力、延误及停车次数等主要交通运行参数的变化做定量分析；结合综合待行区预信号 设置规则，给出两种配合不同主信号相序的预信号设置方案及计算公式；运用VISSIM微观交通仿真软件以昆明市北京路-霖雨路的实际调查数据为例对评 价结果进行验证，证明了理论分析结果的有效性。研究表明：对于过饱和条件下的城市主干道平面交叉口，设置综合待行区能够有效提高交叉口通行能力 、降低车均延误，对交叉口交通运行效益的改善效果较为显著，而不合理的协调配时方案对综合待行区的改善效果有消极影响。
