1The time be the light traffic state, the magnitude of traffic flow is higher than a certain setting value V
2Shi Weichong traffic behavior, the magnitude of traffic flow are higher than a certain setting value V
1, be lower than another setting value V
2The Shi Weizhong traffic behavior; On microcosmic, again regional coordination is controlled operational mode and be divided into traffic control and three kinds of operational modes of regional coordination light traffic control in the control of regional coordination heavy traffic, the regional coordination, line coordination control operational mode is divided into traffic control and three kinds of operational modes of line coordination light traffic control in the control of line coordination heavy traffic, the line coordination, single spot optimization control operational mode is divided into traffic control and three kinds of patterns of single spot optimization light traffic control in the control of single spot optimization heavy traffic, the single spot optimization; The macro operation pattern of traffic signal control system is carried out the timing conversion according to built-in timetable, and the microcosmic operational mode is carried out self-adaptation according to real-time traffic states and changed automatically.
Traffic signal control system by built-in timetable being divided into several periods in one day, each period is specified a kind of macro operation pattern, when system's operate as normal, at first select a kind of macro operation pattern according to built-in timetable, under this macro operation pattern, select corresponding microcosmic operational mode automatically then according to real-time traffic states, to be that single-point induction control or the multi-period timing controlled of single-point or single-point are yellow dodge control if the macro operation pattern is selected, so just no longer selects the microcosmic operational mode.
Regional coordination control operational mode has the highest priority level, and line coordination control operational mode is taken second place, and single-point control operational mode is minimum.
Under single-point control operational mode, single spot optimization has the highest priority level, secondly is single-point induction control operational mode, follows by the multi-period timing controlled operational mode of single-point, and the priority level of the yellow sudden strain of a muscle control of single-point operational mode is minimum.
When the regional coordination heavy traffic under traffic signal control system is just operating in regional coordination control operational mode is controlled operational mode, during if the real-time traffic states at most of controlled crossing all reaches in a period of time inner control zone thereafter during traffic behavior, the operational mode of system just converts regional coordination automatically to and controls traffic control pattern in the regional coordination under the operational mode so; If what reach is the light traffic state, the operational mode of system just converts the regional coordination light traffic control operational mode under the regional coordination control operational mode automatically to so.
Priority ranking according to the macro operation pattern when system's generation catastrophic failure carries out the conversion of order degradation automatically.
