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.
