【摘要】 由于各方面原因,通过交叉口的交通流量可能会不断发生变化,对定时信号控制的交叉口来说,原来的信号配时就可能不再适合交通流量改变之后的交叉口,以至产生交通拥堵。以光华—南熏交叉口为例,调查交叉口的交通流量、延误和信号配时,并运用交通流理论分析交叉口交通流量,利用VISSIM对其进行模拟仿真,找出拥堵路口,然后对其进行配时改进,再对改进后的配时进行仿真评价。实践证明,交通流被合理分配,交通拥堵得到消除。更多还原

【Abstract】 The traffic flow might be always changing for many reasons, which may make the signal timing not match with the intersection whose traffic flow has changed. Thus it brings about congestion. Taking GuangHua-NanXun intersection for example, the traffic flow, delay and signal timing are investigated and traffic flow theory is utilized to analyze the practical flow. Meanwhile traffic simulation software VISSIM is used to find out the congested intersection and improve the timing level. The prefected timing is evaluated. The practice proves that traffic flow is distributed rationally and the traffic jam is solved.更多还原
