摘　　要：目前在信号交叉口方案优化时,渠化组织优化研究与信号配时优化研究相分离,从而影响了研究的整体效果。文中以北京市怀柔区的典型交叉口为例进行分析研究。在实际调查的基础上进行特性分析,利用Synchro仿真软件对信号交叉口的现状信号配时方案进行分析,并对配时方案进行优化。结合分析结果,判断渠化组织的合理性,再根据渠化组织确定相应信号配时方案。将信号配时优化与渠化组织协同考虑,最终确定推荐的渠化与信号配时设计方案。When studying signal timing optimization presently, the researchers often make a separated study of canalization and that of signal timing optimization respectively. As a result, the effectiveness is reduced as a whole. This paper took the typical signalized intersection of Huairou District in Beijing for an example. Based on the actual investigation data, this paper analyzed the traffic characteristics, presented the situation signal timing scenario of the signaled intersection and optimized the signal timing scenario using the Synchro simulation software. Combined with the intersection geometry condition and the analysis result, it judged whether the current canalization design was reasonable or not, and then determined the corresponded signal timing plan. Both signal timing optimization and the canalization design were considered simultaneously, and the recommended design scenario of the canalization and the signal timing was obtained finally.
