中文摘要：

在现有道路交通设施条件下,实现干道上信号协调控制能有效提高主干道的通行能力。以厦门市白鹭洲路为研究案例,根据该道路的几何结构特征和实际交通流特点,提出＂分时段分方向、设置半周期时长＂的干道信号协调控制方法,应用Synchro仿真软件建立基于原控制参数的干道信号协调控制系统;同时,在应用Synchro优化各个独立交叉口信号控制参数的基础上,建立了基于优化控制参数的信号协调控制系统。通过比较优化前后的干道信号协调控制系统的控制效果,仿真结果显示：在早高峰和晚高峰时段,交叉口延误分别降低11.3%和21.6%;干线延误分别降低8.2%和55.9%;路网总延误分别减少13.3%和22.0%。

英文摘要：

A signal coordination control system on an arterial road can effectively improve the capacity of existing transportation facilities.Taking the Bailuzhou Road in Xiamen city as an research object,this paper proposes the signal coordination control method＂with different directions,at different periods,and at half-cycle length＂according to the geometric structure characteristics and the survey data.Based on Synchro,the signal coordination control system is established.The simulation results of traffic operational states on this arterial road indicate that the average intersections delay is reduced by 11.3% and 21.6% respectively,and the average arterial delay is reduced by 8.2% and 55.9% respectively,while the total delay of the road network is reduced by 13.3% and 22.0% respectively during the morning and evening peak hours.
