摘　　要：针对进口单独放行的信号相位设计方式,遵循绿波带宽度最大化设计理念,利用干道协调控制中的时距分析方法,给出了进口单独放行方式下的干道双向绿波协调控制数解算法。通过优化选取各交叉口的信号相序组合,确定干道交叉口的最佳公共信号周期与相位差取值,计算不同干道行驶方向的绿波带宽度。分析结果表明:与进口对称放行方式下的数解算法相比,进口单独放行方式下的数解算法能使理想交叉口间距取值具有更大的选取空间,更适合于对交叉口间距不齐的多个干道交叉口进行绿波协调控制;进口单独放行方式下的干道双向绿波协调控制方法能够获得较好的控制效果,特别是对于交叉口间距参差不齐的干道交通条件同样具有较强的适应性。Aimed at signal design mode of one-phase-one-approach,following the design principle of maximum green wave bandwidth and making use of the time-space analysis method,a new algebraic method of arterial road coordinate control for bidirectional green wave which can be used in the signal design mode of one-phase-one-approach was presented.This method can be used to optimize the phase sequence of each intersection,determine the optimal common signal cycle and signal offsets,and calculate the green wave bandwidth in different arterial road directions.Analysis results show that compared with the algebraic method in the signal design mode of one-phase-symmetry-flow,this method can be used to select the ideal intersection spacing in a larger range and more adapts to the situation which the intersection spacings are uneven.The algebraic method in the signal design mode of one-phase-one-approach has good control result,even if the intersection spacings are uneven.
