Description
Technical field
The invention belongs to the green ripple control technology of main line in traffic signalization field, relate to a kind of cooperation control timing method making arterial highway two-way green wave bandwidth maximum.
Background technology
The crossing of China on urban road network arterial highway mostly is signalized crossing, carries out vehicle when single point signals controls respectively and frequently stops in crossing, therefore causes the traffic problems such as road network operational efficiency is low, trip delay increase.For reducing the down time of vehicle on each intersection, a collection of adjacent traffic signal on a main line being united, in addition cooperation control, reducing traffic delay and the parking rate of wagon flow on main line, the whole urban traffic conditions of improvement is significant.
The principle of design of timing arterial highway green ripple signal coordinated control mainly contains two kinds: the wide maximization of green wave band and delay minimize.Wherein green wave band wide maximization method for designing is the green time difference by changing each crossing on main line, pursue the maximization of theoretical green ripple transit time and common signal periodic ratio, namely using the theoretical green wave band width in signal spacetime diagram as the evaluation index of timing scheme cooperation control effect.Common method ills method and algebraic method.Wherein graphical method is intuitively easy to operate, but subjectivity is comparatively large, and situation when being not suitable for that on main line, crossing is more.And algebraic method has advantages such as calculating succinctly, realization is convenient, workable, and be used widely in some arterial road coordinate control actual system design, in many textbooks, also it can be used as classical way to be introduced.
But can be found by graphical method checking, the green wave band of the timing scheme that traditional algebraic method provides is wide is not that maximum green wave band is wide.In addition, the scheme of the change speed limit that traditional algebraic method proposes is difficult to realize in arterial highway, actual cities, and in fact the speed limit of urban trunk is all generally unified, and the travel speed of vehicle on same section is also relatively stable.Moreover traditional algebraic method only considered the wide calculating of green wave band ideally, does not consider the delay situation that may occur in actual section, the delay that causes of queuing vehicle in advance of the delay produced as bus stop station and crossing.
In order to overcome above-mentioned defect, the present invention improves conventional rail signal coordinated control number solution method, under prerequisite easy to implement, to consider actual vehicle performance in operation, proposes a kind of based on green wave band width maximized arterial highway Philodendron ‘ Emerald Queen' timing new method.
