Multi-phase signal setting and capacity of signalized intersection
摘要
Abstract
A capacity model of multi.phase signalized mtersections is derived by a stopping-line metllod.It is simplified wRh two normal situatiOns:one situation involves one straight lane and one left-turn lane;the Other situation involves two straight Ianes and one left-turn lane.The results show that the capacity is mainly relative to signal cycle length,phase length,intersection layout and following time.With mgard to the vehities amval rates,the optimal model is derived based on each phase's remmmng time balance,and it is solved by Lagrange multipliers.Therefore.the calculation models of the optireal signal cycle length and phase lengths are derived and simplified.Compared to the exastang models,the proposed model is more convenient and practical.Finally,a practical intersection is chosen and its signal cycles and phase lengths are calculated by the proposed model.关键词
