摘　　要：线控周期时长取决于系统中单个交叉口周期时长的最大值,所以合理地计算每个交叉口的周期时长和绿信比就显得尤为重要.建立了基于单点交叉口延误最小的周期时长和绿信比的优化模型,给主干道分配更长的绿灯时间,给非主干道分配更短的绿灯时间.Line control cycle length is decided by the maximum cycle of all intersections of a system, so it is very important to reasonably calculate the cycle length and split at every junction. An optimization model of cycle length and split at separate intersection was established based on minimum delay to allocate more time for green light at arterial street but shorter time at non-primary routes.

关 键 词：交叉口 周期时长 绿信比 延误分析
