Fixed control strategies are based on a signal-timing plan defined in terms of operating parameters for traditional signal control,namely cycle time,splits,and offsets.These parameters are generally developed based on traffic studies and standard procedures,such as the Highway CapacitiManual,or signal timing software such as TRANSYT and PASSER.The traffic studies result in estimates of trafficconditions,link volumes and turning percentages,for specified time periods.Signal timing parameters are developed for each of these time periods and,typically,implemented on a time-of-day basis with no consideration of current actual traffic conditions.In many cases,even the use of standard procedures for the development of signal timing plans is abandoned and traffic engineers operate in judgment-based fashion with moderate levels of success.None of these approaches is truly traffic-adaptive or even attempt to actually minimize some measure of traffic performance such as average vehicle-delay.

定额控制战略,是基于对信号的定时计划的角度界定操作参数,传统的交通信号控制,即周期时间,分裂和偏移量.这些参数一般都基于交通的研究和标准程序而制定,如公路容量手册或信号定时软件,如transyt和passer.交通研究结果估计传输条件 ,联系册,并把百分比,为指定时段.信号时序参数为每一个这些时段,通常情况下,实施的时间- -天同的基础上,没有考虑目前的实际交通情况.在很多情况下,即使使用的标准程序,为发展信号配时方案是放弃和交通工程师在判决基础的时装中度水平的成功.这些做法没有一个,是真正的交通自适应或企图实际上最大限度地减少了一些措施交通的表现,如车辆平均延迟.
