Anti-blocking system of this traffic planninng and anti-blocking method; In Fig. 5; Two steps, the circuitous method of turning left was accomplished in two steps; This craspedodrome signal lamp 18 and these are behind belisha beacon 19 green lights before mouth of the first step; Stride across the crossing earlier, return at this multiple U-shaped behind mouth and wait before turning signal lamp 20, second step was waited this to return to multiple U-shaped behind the mouth and passes a mouthful back multiple U-shaped after turning signal lamp 20 green lights again and return and turn track 11; Turn right then, craspedodrome signal lamp 21 and reverse belisha beacon 22 send out a warning before the at this moment reverse mouth.This craspedodrome signal lamp 18 before mouth of first road is to return to through vehicles and reverse mouthful of back for fear of this to turn vehicle and clash and set up; This is to clash and set up to through vehicles and left-hand or dextrad driving vehicle for fear of this to belisha beacon 19 for second road; This multiple U-shaped behind mouth of the 3rd road returns and turns 20 in signal lamp and limit this and turn vehicle to returning, and this is unrestricted to through vehicles.Otherwise craspedodrome signal lamp 21 before reverse mouthful, reverse belisha beacon 22, reverse mouthful of multiple U-shaped in back return that to turn signal lamp 23 effects as the same.In Fig. 6; Two steps, circuitous craspedodrome method first step through vehicles was turned right earlier; Return with multiple U-shaped behind the left-hand mouth and to turn vehicle and merge together; Multiple U-shaped returns the green light signals that turns signal lamp 27 after waiting the left-hand mouth; Two steps of this moment, circuitous craspedodrome signal lamp 25 green lights were bright, and left-hand craspedodrome belisha beacon 24 red lights are bright; After second step waited behind the left-hand mouth multiple U-shaped to return to turn signal lamp 27 green lights, pass a mouthful right multiple U-shaped and return and turn track 10, turn right then, this moment, the dextrad mouthful front blinker 26 of keeping straight on was a red light.Circuitous craspedodrome signal lamp 25 of two steps is to specialize in the special-purpose traffic lights of circuitous through vehicles of two steps, and the setting of its green light will be avoided the flowing water period of left-hand through vehicles, and reserves the time enough surplus, guarantees that the flowing water that can not therefore hinder the left-hand through vehicles travels.In Fig. 7, do not say or talk vehicle two step is circuitous turn left the method first step with this to the craspedodrome signal Synchronization, by arrival B position, A position; And then B location pending dextrad craspedodrome signal lamp; After second step treated that dextrad craspedodrome signal lamp was bright, the express of keeping straight on dextrad arrived the C position by the B position synchronously, and completion is turned left.The thing of being accomplished by a step was decomposed into for two steps, had avoided accident and had conflicted, and the craspedodrome wagon flow is had no influence.In Fig. 8; The method first step is walked in pedestrian's two step segmentations; On the center safety islands 32 such as pedestrian first walk and begin to follow people's zebra stripes 1 after signal lamp 28 or the first reverse pedestrian walk signal lamp 30 green lights and walk to center safety island 32 and wait for to the pedestrian; Walk signal lamp 28 when giving a green light to the pedestrian for first here; Left-hand vehicle craspedodrome signal lamp 35 sends out a warning just; And the first reverse pedestrian walks signal lamp 30 when giving a green light, and dextrad vehicle craspedodrome signal lamp 36 sends out a warning just; Second step waited second to walk signal lamp 29 or the second reverse pedestrian when walking signal lamp 31 green lights to the pedestrian; The pedestrian walks to the road opposite by center safety island 32; Walk signal lamp 29 when giving a green light to the pedestrian for second here; Left-hand vehicle craspedodrome signal lamp 35 sends out a warning; And the second reverse pedestrian walks signal lamp 31 when giving a green light, and dextrad vehicle craspedodrome signal lamp 36 sends out a warning.
Anti-blocking system of this traffic planninng and anti-blocking method are carried out flowing water to the through vehicles at crossing and are travelled, and its specific embodiments is following:
Say several definition and rule at first earlier:
1, green light cycle period: after all wagon flow combinations of crossing; We are defined as the green light cycle period whole Combined Cycle green time sums once; In this research, the green light cycle period that we set the crossing is 4t, and we are defined as basic time unit of the present invention t.The green light cycle period has three characteristics, and the one, cyclicity, from 0t-4t, every separated 4t comes again, and moves in circles.The 2nd, uniqueness, a city is an integral body, and we want the traffic lights at these all crossings, city of integrated planning, and we stipulate that any one green light cycle period that is provided with the traffic lights crossing all is 4t.The 3rd, changeability, green light cycle period 4t is associated in the flowing water speed of a motor vehicle, is corresponding, variable, i.e. the flowing water speed V
1* 4t
1=flowing water speed V
2* 4t
2, i.e. V
1* t
1=V
2* t
2, t here
1, t
2Be respectively and V
1, V
2Two corresponding basic time units.
2, the green light period: combination or the transit time section of a round-robin green light of one wagon flow initial moment to finish time, we are referred to as the green light period of this combination or this burst wagon flow.We are called the green light duration time span of green light period, no matter beginning of green light duration and ending only are time spans, and existing time span of green light period, the moment that beginning is arranged again and end up.
3, the flowing water period: each crossing green light of the through vehicles that flowing water travels begins all will begin with ending corresponding respectively with next crossing green light with ending; The crossing green light period of flowing water driving vehicle is also referred to as the flowing water period at crossing; The flowing water period not only has at the crossing; All there is the flowing water period in any position on the whole piece road; Equally; The time span of flowing water period is called the flowing water duration, and the period beyond the through vehicles flowing water period, we were called the idle period of through vehicles.
4, time gap: at the uniform velocity we are called the time gap at these two crossings to vehicle the used time from a crossing to next crossing with the flowing water speed V.
Path distance: in order to distinguish mutually with time gap, we claim that the actual range at two crossings is a path distance, and path distance equals the flowing water speed V and multiply by time gap obviously.
5, the complementary principle of crossing area and transit time, the green light transit time of crossing runway quantity and vehicle can compensate each other, and a side is if can not transfer greatly, and we can transfer big the opposing party, to reach the purpose that satisfies vehicle pass-through.
(1) basic scheme one: the adjacent intersection time gap is 1t, and through vehicles flowing water duration is 1t.
Figure 9 straight in all directions in order to solve the vehicle can travel water problem, we start with the easiest to start with the most basic, we require are parallel or perpendicular to the road, adjacent to the intersection of all time distance are 1t, each 8 shares a traffic intersection in the four directions, respectively, and four straight direction traffic traffic we set left straight and left for each traffic direction as a group, we use the symbol?
to represent the straight and turn left to the combinations.So that a total of four combinations of four directions, respectively?
Meanwhile we require equal access for each combination takes time, that?
the green movement time, the actual combination of these four periods were occupied by green 0t-1t, 1t ~ 2t, 2t ~ 3t, 3t ~ 0t (4t), 0t (4t) ~ 1t (5t), 1t (5t) ~ 2t (6t) ...... 4t 0t and from the beginning after the cycle, 4t is a cycle.According to top fundamental figure such as Fig. 9 that stipulates to have drawn we all directions through vehicles can both flowing water travels. the line among the figure is represented the road, and the intersection point of two lines is the crossroad, and we are also referred to as node in the drawings.
indicates reverse straight and turn left green light period is 1t-2t, 1 meaning the starting time for the green light to 1t.
Left to go straight and turn left represents the green light period is 2t-3t, 2 meaning the starting time for the green light to 2t.
means the right and left of the green light to go straight hours of 3t-0t, 3 meaning is green starting time for 3t.
showing the green light to go straight and turn left the starting time for 0t, green period is 0t-1t.Between the node on the line target numeral " 1 " to represent the time gap between the crossing be 1t.From node diagram, can find out when this when being 0, then oppositely be decided to be 1, two other direction must be for being respectively 2 and 3; When this then oppositely must be 3 when being 2, two other direction is respectively 0 and 1.
The road that any flowing water travels; The initial moment sum of the green light of each positive and negative both direction in crossing is two fixed values on its whole piece road; The relation of these two fixed values: supposing one is a; Then another is that a+4 (when a＜4) or a-4 (when a＞4) these we are called the node theorem; For example: please see that the lower left corner node a of Fig. 9 is for like accompanying drawing 19
(1) this to the initial moment sum of reverse green light be 0+1=1; So along this to each crossing, whole piece road of direction or inverse direction its to being 1 or 1+4=5 with the initial moment sum of reverse green light; Please be with the aid of pictures; Along this to each crossing upwards its be respectively: first 0+1=1; Second 1+0=1; The 3rd 2+3=5, the 4th 3+2=5,
(2) the initial moment sum of left-hand and dextrad green light is 2+3=5; So along each crossing, left and right direction whole piece road; The both direction green light plays constantly sum and is 5 or 5-4=1; Please be with the aid of pictures: along left-hand to the right each crossing its be respectively: first 2+3=5; Second 3+2=5; The 3rd 0+1=1, the 4th 1+0=1,
This theorem is applicable to road and the crossing that any flowing water travels, and also meets this theorem in any one position of road (being not only the crossing).
As can be seen from Figure 9 through vehicles is with the flowing water speed of a motor vehicle; At the uniform velocity driving to the craspedodrome green light that the used time of next crossing is each crossing of 1t begins to begin to distinguish corresponding with ending with the craspedodrome green light of ending with next crossing; Be that vehicle drives to next crossing with the flowing water speed of a motor vehicle when green light begins at the crossing; Also be that green light begins just; When green light ends up, at the uniform velocity travelling to following crossing with the flowing water speed of a motor vehicle also is the green light ending just; The through vehicles of all directions is as long as travel by the flowing water speed of a motor vehicle; All can reach the effect that flowing water travels, here the flowing water duration of through vehicles is 1t.
(2) basic scheme two: the adjacent intersection time gap is 0.1t, and through vehicles flowing water duration is 1t.
Still meet the regulation of node theorem like all nodes of Figure 10, the initial moment sum of the through vehicles green light of the positive and negative both direction of any node is 1 or 1+4=5.As can be seen from the figure; Most of crossing vertically with laterally do not clash; Can both accomplish that all directions through vehicles flowing water travels; The following intercepting lower left corner such as Figure 20 node section; This time gap is that the square of 1t is made a concrete analysis of; The crossing meter is 100 in this square road network; Wherein 80 crossings can reach all directions through vehicles completely flowing water travel; There is conflict the flowing water period of the vertical and horizontal at other 20 crossings (enclosing next crossing with pen); But conflict spectrum is different; Be respectively that minimum 8 crossings of the first kind of conflict are respectively 4 node b such as accompanying drawing 21 and 4 node c such as accompanying drawing 22; Second type of bigger 6 crossing of conflicting are respectively 3 node d such as accompanying drawing 23 and 3 node e such as accompanying drawing 24; The 3rd type of bigger 4 crossings of conflicting are respectively 2 node f such as accompanying drawing 25 and 2 node g such as accompanying drawing 26, and the 4th type of maximum 2 crossings of conflict are respectively node h such as accompanying drawing 27 and node i such as accompanying drawing 28.We change the green light at these crossings that the clash craspedodrome period into node j such as accompanying drawing 29 and node k such as accompanying drawing 30 respectively; The craspedodrome green time of 8 crossing all directions of the first kind just has the time period of 0.9t to overlap with the flowing water period so, that is to say that 90% through vehicles can reach the state that flowing water travels at this crossing.Give an example at present and specify: origin node node b such as accompanying drawing 21 are node j such as accompanying drawing 29 at present, with this to being that example explains.This is 0.4t～1.4t to the flowing water period; And this is 0.5t～1.5t to the green light period now; Obviously the time period of 0.5t～1.4t meter 0.9t overlaps, and therefore in the green time that amounts to 1t, has the time of 0.9t to travel by flowing water, and other node of other direction can be by that analogy.
Therefore we reach a conclusion:
1. in this scheme, have 80% crossing can reach all directions through vehicles completely flowing water travel
2. the flowing water that has the crossing of 8 ÷ 100=8% can reach all directions through vehicles 90% travels
3. the flowing water that has the crossing of 6 ÷ 100=6% can reach all directions through vehicles 80% travels
4. the flowing water that has the crossing of 4 ÷ 100=4% can reach all directions through vehicles 70% travels
5. the flowing water that has the crossing of 2 ÷ 100=2% can reach all directions through vehicles 60% travels
5, the scope of application: all can use this scheme when the time gap between the crossing is the integer multiple of 0.1t and make through vehicles reach the effect that flowing water travels basically.Specifically: 1. suppose t=0.5 minute, flowing water speed V=40km/ hour, then the path distance S=of 0.1t (0.1 * 0.5 ÷ 60) * 40=0.033=33 rice.33 meters is very short distances, and this can illustrate that in existing urban road we can reach the state that each crossing all directions through vehicles flowing water travels basically with this method.
2. in practical operation; Because the craspedodrome wagon flow is a major flow; The vehicle of turning left is less, and the green light period that these two bursts of wagon flows are all enjoyed 1t obviously is irrational, and we can extend the craspedodrome green light period at crossing; But in will being included in the flowing water period of 1t; Shorten simultaneously and turn left the green light period, concrete lengthening how much, be according to actual needs; For example, the craspedodrome green light period adds and grows to 1.5t (the flowing water period that wherein the contains 1t) period of then turning left and just foreshorten to 0.5t.
In this scheme; If we remove the road that flowing water fully travels; Then can find out; Fully the flowing water zone of travelling is spaced apart uniformly with the zone that flowing water fully travels; Separated therebetween distance is 0.5t, and this is our clear and definite direction in road flowing water travels Rule Design.
(1) extension program one: time gap is 2t, and the flowing water duration is 2t.Like Figure 11,
1, as can be seen from the figure, this scheme has following characteristics:
1. the time gap between all adjacent intersections is 2t, and the craspedodrome flowing water duration of all any directions in crossing is 2t;
2. from node diagram, can find out; In crossing green light cycle period the time at whole 4t; Vertically with the time that laterally respectively takies 2t; And this is to splitting simultaneously with reverse craspedodrome wagon flow; The craspedodrome wagon flow of left-hand and dextrad is also opened green light simultaneously; If vertically split simultaneously for 0t, then laterally must be for 2t split simultaneously, vice versa;
3. the green light transit time of turning left that has not just had like this vehicle, we can be before mouth be established at the crossing multiple U-shaped return turn, mouthful multiple U-shaped in back returns and turns, also can be in the road suitable position establish multiple U-shaped and return and turn.
(2) extension program two: time gap is 2t, indivedual direction flowing water duration＞2t.Like Figure 12,
This scheme and extension program one are basic identical; The key distinction is: crossing green light cycle period 4t divides equally to vertical and horizontal; But it laterally is the green light period of 2.5t; It is the green light period of 1.5t vertically; This scheme is very suitable for the more strip city of lateral vehicle, and the horizontal green light period also can be 2.3t, 2.4t certainly ... Deng, and vertically also can be 1.7t, 1.6t simultaneously ... Deng; Therewith roughly the same, no longer detail.
(3) extension program three: 1t＜flowing water duration＜2t, and like Figure 13,
The craspedodrome flowing water period of preceding two extension programs is all green light cycle period 4t absorb; The crossing does not have the unnecessary time to turn left; And this scheme all directions craspedodrome flowing water duration is all less than 2t, and all there is the green time of turning left at the crossing, and can not establish multiple U-shaped in crossing and the road and return and turn the track.Like Figure 13 flowing water duration of keeping straight on is 1.4t, and the green light duration of turning left is 0.6t.Obviously, this program can reach all the roads straight vehicles running water, the water when the length of 1.4t, the length of each direction are left green 0.6t, now to the drawings 31 node m as an example, the green light in all directions period to be specified: 0t-0.6t:?
0.6t-1.4t:?
1.4t-2t:?
2t-2.6t:?
2.6t-3.4t:?
3.4t-0t:?
This program has an obvious feature : The time from the roads were? 0.6t and 1.4t in the form of spaced, both vertically and horizontally.And 0.6t just is the green light duration of turning left, and 1.4t is a craspedodrome green light duration.Therefore we are time gap that zone between two roads of 0.6t calls " zone of turning left ", are time gap that the zone between two roads of 1.4t calls " zone of keeping straight on ".Further discover, can add road arbitrarily in " zone of turning left ", the craspedodrome wagon flow at each crossing can both reach flowing water travels, and can not add any road " keep straight on zone ", otherwise through vehicles can clash, and can not reach complete flowing water and travel.
We further explanation and demonstration example, we in the "left area" lateral and longitudinal additional two roads, respectively, in Figure 14, it is clear that the program can reach all the roads straight vehicles running water, and its duration were 1.4 water t, all directions are too long when the green left 0.6t, but there is little downside is some time left turn in one cycle divided into two sections, now move node n are as Figure 14 do specify, 0.1t- 0.7t:?
0.7t-1.5t:?
1.5t-2.1t:?
2.1t-2.5t:?
2.5t-3.5t:?
3.5t-3.9t:?
3.9t-0.1t:?
In this node , reverse left of the green period divided 2.1t-2.5t 0.4t and 3.9t-0.1t meter meter 0.2t two periods.Therefore we sum up a rule; When the green light duration of turning left is at; When craspedodrome flowing water duration is (2-a) t (1＜2-a＜2); Its flowing water scheme of travelling is: " the at zone of turning left " is spaced apart with " (2-a) t zone of keeping straight on "; And Nei Keren establishes road and all directions through vehicles still can reach flowing water and travels at zone; In (2-a) t zone, can not add any road, otherwise can clash, make through vehicles can not reach complete flowing water and travel.
(1) integration scenario one:
Like Figure 15: 1, double solid line is major trunk roads, and single solid line is a subsidiary road, and the flowing water speed of a motor vehicle of major trunk roads vehicle is V, and the flowing water speed of a motor vehicle of subsidiary road vehicle is 2/3V.Same like this path distance, vehicle is with the time of 2t on the major trunk roads, and the vehicle on the subsidiary road was accomplished with regard to the time that needs 3t.
2, the time gap of adjacent major trunk roads is 2t, on the major trunk roads between two adjacent intersections trisection, on Along ent, establish subsidiary road, the time gap of adjacent intersection is 2/3t on the major trunk roads like this.And the time gap of adjacent intersection is 3t/3=1t. on the subsidiary road
3, the equal flowing water of wagon flow of all directions travels on all major trunk roads, and its flowing water duration is 2t, in the square region that each major trunk roads surrounds, the equal flowing water of all directions wagon flow travels on all subsidiary roads, and its flowing water duration is 1t.Vehicle flowing water in this scheme on the major trunk roads travel be consistent from start to finish, but the flowing water on the subsidiary road is zonal.When vehicle stride major trunk roads from a zone to another when zone, have of short duration can not travel by flowing water in short-term of waiting.
4, the ordering of primary and secondary wagon flow is: 1. at first be the craspedodrome wagon flow on the major trunk roads, the planning of road and traffic lights will be the center with it with being provided with.2. secondly be the wagon flow of turning left on the subsidiary road when intersecting on subsidiary road and the major trunk roads, the vehicle of turning left at this crossing will be far away more than through vehicles obviously.3. the craspedodrome wagon flow on the subsidiary road.
5, crossing:
1. the intersection of major trunk roads and major trunk roads; We select crossing wagon flow assembled scheme shown in Figure 180 for use; Be not establish on the major trunk roads to turn left; Only establish vertical and horizontal two-way craspedodrome; Simultaneously before the crossing is with the peripheral hardware mouth with mouth after multiple U-shaped return and turn, set up simultaneously this multiple U-shaped before mouth return turn signal lamp 37 with reverse mouthful before multiple U-shaped return and turn signal lamp 38.
2. the intersection of subsidiary road and major trunk roads; The all directions craspedodrome is marked the flowing water period by Figure 15 and is carried out; Still do not establish on the major trunk roads and turn left; Also not establishing a mouthful back multiple U-shaped returns and turns; Only establish craspedodrome on the major trunk roads, turn right and mouthful before multiple U-shaped return and turn; And return at the multiple U-shaped of Lu Zhongshe and to turn, subsidiary road is turned left with reference to shown in Figure 1 to major trunk roads, is provided with the left-hand special-purpose transition track of turning left
7, can realize vehicle turning left on the subsidiary road smoothly to major trunk roads.
The green light duration of first period: 10t/3～4t (0t)～2t/3 meter 4t/3.Major trunk roads this to keep straight on mouthful before return turn and the subsidiary road left-hand to turn left be a combination, take the same green light period, major trunk roads center safety island left side stream of people gives a green light in this period, do not say or talk craspedodrome in major trunk roads right side gives a green light, at this moment other wagon flow sends out a warning.
The green light duration of second period: 2t/3～4t/3 meter 2t/3, major trunk roads are two-way to be split.The beginning of this period just is the beginning of the reverse wagon flow of major trunk roads, and ending just is this ending to wagon flow.
The duration of the green light of the 3rd period: 4t/3～8t/3 meter 4t/3.It is these endings to wagon flow of major trunk roads that this period begins.The ending of this period is the ending of reverse wagon flow.These period major trunk roads reverse keep straight on return turn and subsidiary road dextrad to turn left be a combination, during this time the center safety island right side stream of people gives a green light.Major trunk roads left side do not say or talk is kept straight on and is given a green light, and other wagon flow sends out a warning.
The green light duration of the 4th period: 8t/3～10t/3 meter 2t/3 all is that idle period all sends out a warning in the two-way craspedodrome of these period major trunk roads, and the two-way craspedodrome of subsidiary road gives a green light.Two steps, the circuitous traffic lights that pass through the stream of people of major trunk roads all gave a green light, and the slow train stream on the subsidiary road gives a green light simultaneously.Major trunk roads this to reverse mouth before multiple U-shaped return and turn wagon flow and all give a green light.The intersection of other main and secondary road is no longer detailed by that analogy.
(2) integration scenario two:
Like Figure 16: 1, in this scheme, double solid line is represented major trunk roads, and single solid line is represented subsidiary road, and the flowing water speed of a motor vehicle of vehicle is V on the major trunk roads, and the flowing water speed of a motor vehicle of vehicle is 3/5V on the subsidiary road.
2, the time gap of adjacent major trunk roads is 6t; In this 6t scope; On the time gap position of 2.25t, 1.5t, 2.25t, establish subsidiary road respectively; The time gap at crossing is respectively 2.25t, 1.5t, 2.25t, 2.25t, 1.5t, 2.25t on the major trunk roads like this ... The major trunk roads both sides are 2.25t; The centre is 1.5t, and the time gap at each crossing is 2.25t ÷ 3/5=3.75t, 1.5t ÷ 3/5=2.5t, 2.25t ÷ 3/5=3.75t on the corresponding therewith subsidiary road ...
3, the craspedodrome wagon flow current-sharing water of all directions travels on all major trunk roads; The flowing water duration is 2t; On all subsidiary roads the craspedodrome wagon flow of all directions also flowing water travel; The flowing water duration is 1.5t; The difference of this scheme and previous scheme is, the wagon flow on the subsidiary road no longer is that regional flowing water travels all is that flowing water travels from start to finish.
4, crossing
1. major trunk roads are identical with integration scenario one with the intersection of major trunk roads, no longer here chatting more.
2. the intersection of major trunk roads and subsidiary road.
According to wagon flow planning with make up different, multiple different type can be arranged, but the initial moment of node craspedodrome wagon flow be constant, we can select as required for other.
Junction node is given an example, like node q such as accompanying drawing 34,
First type: main, subsidiary road is not all established and is turned left; Return to turn with mouthful multiple U-shaped in back before all establishing mouthful and also be divided into four periods; Be respectively: the green light duration of first period 1.75t～2.25t meter 0.5t, major trunk roads dextrad keep straight on reach back turn and subsidiary road on vehicle return and turn; Second period was the green light duration of 2.25t～3.75t meter 1.5t, and vehicle returns and turns on two-way craspedodrome of major trunk roads and the subsidiary road; The 3rd period was the green light duration of 3.75t～0.25t meter 0.5t, the major trunk roads left-hand keep straight on reach back turn and subsidiary road on vehicle return and turn; The 4th period was the green light duration of 0.25t～1.75t meter 1.5t, and vehicle returns and turns on two-way craspedodrome of subsidiary road and the major trunk roads.This type major trunk roads craspedodrome flowing water duration is 2t; Subsidiary road craspedodrome flowing water duration is 1.5t; Turn duration and be 2t for multiple V-shaped time before the main and secondary road mouth and behind the mouth; Return and to turn duration and in fact do not need so long green light duration; Can shorten with craspedodrome flowing water period in the close moment, in order to avoid influence the craspedodrome flowing water of main and secondary road, the time that the pedestrian walks on the major trunk roads; Also reach the duration of 2t, this duration also can suitably reduce in order to avoid influence each other with the craspedodrome wagon flow.
Second type: major trunk roads are only established before the mouth multiple U-shaped and are returned and turn and keep straight on, and establish subsidiary road simultaneously and turn left and keep straight on.Also be divided into four periods: first period was that 1.75～2.25t counts 0.5t green light duration, and major trunk roads dextrad is kept straight on and mouth turns for preceding time and subsidiary road originally turns left; Second period was the green light duration of 2.25t～3.75t meter 1.5t, the two-way craspedodrome of major trunk roads; The 3rd period was the green light duration that 3.75t～0.25t counts 0.5t, and the major trunk roads left-hand is kept straight on and mouth turns for preceding time and subsidiary road is oppositely turned left; The 4th section is the green light duration of 0.25t～1.75t meter 1.5t, and multiple U-shaped returns and turns before two-way craspedodrome of subsidiary road and the major trunk roads bidirectional interface.
The third type---second type variation; First three period is all identical; Only the 4th period was divided into two periods; The two-way craspedodrome of period subsidiary road; Taking out a period in addition is used for the two-way of subsidiary road and turns left, and this is mainly used in subsidiary road to the major trunk roads more situation of vehicle of turning left.
Certainly can also this several types make up for the basis and form new pattern, this mainly comes calmly as required.
Method according to front two cover integrated suites schemes; Sum up the method for seeking a spouse and ask strange method; The said method of seeking a spouse; It is the even-multiple that time gap between all crossroads of main roads is t; Be 2t, 4t, 6t etc.; Therefore we are when the planning road is provided with traffic lights; No matter newly-built city still is old city; The time gap that all will make every effort between the main roads is the even-multiple of t; Only in this way could realize that the crossing vertically reaches horizontal craspedodrome and splits, realize the maximum transit time of all directions through vehicles.Saidly ask strange method; On the major trunk roads; Be the odd of t apart from the main crossroads time gap between the main crossroads; We are called singular point this position; This position is that the optimum position of turning for two-way time is set, and only in this position, returns and turns vehicle and can in the shortest waiting time, return and turn; And when craspedodrome flowing water duration≤2t, turning vehicle returning of the positive and negative both direction of singular point can need not in the period to wait for and directly return and turn at whole flowing water.We are on the basis of Fig. 8; The multiple U-shaped of setting up positive and negative both direction vehicle at the zebra stripes two ends respectively returns and turns the track; Setting up multiple U-shaped simultaneously returns and turns signal lamp; This returns to turn with the pedestrian and walks the crossing that highway is combined with regard to having formed the complete vehicle of a cover; Owing to carried out flowing water and travelled; Highway takes up an official post where to put all has the flowing water of through vehicles period and idle period; Therefore we can utilize the idle period place of wanting of what is the need in office that such crossing is set; This has just been avoided the pedestrian to run helter-skelter and vehicle disorderly turns, and can also guarantee that vehicle flowing water travels simultaneously.
Anti-blocking system of this traffic planninng and anti-blocking method, the multistage public transport system of described annular, like Figure 17,
One, annular multistage public transport system: the major trunk roads in length and breadth with the city are that the sideline is divided into several zones to the city; Public transit vehicle is divided into multilevel hierarchy; The big bus of one-level travels on major trunk roads; Walking big circuit (generally has only and keeps straight on and turn right; Do not turn left) the little bus of secondary travels in each zone; Also walk circuit; Also have only and keep straight on and turn right; According to the quantity and the size of the little public transport of size design in zone, the zonule that has even can use mini van as little bus.This is called multistage public transport system and is also referred to as secondary public transport system, if but the central area of big bus travel is very bustling, and ridership is big, and the ridership from far-off regions of travelling is little, at this moment we just add big public transport in central section, still walk circuit.We are called secondary public transport the bus that adds, and three grades of public transport are then claimed in the little public transport in the zone, and we are called three grades of public transport systems this cover system, by that analogy.Level Four ... Pyatyi
In addition the multistage public transport system of annular is also had three requirements:
Only establish 1～2 website when 1, big bus is through each zone
2, best and green light cycle period 4t hook consideration of every station residence time of big bus, big public transport will be networked with traffic lights control center, can in time grasp suitable travel speed, with the website residence time.
3, bus outward appearance at the same level and the same color of station board are familiar with to make things convenient for the passenger.
Two, function distinguishing: big bus travels on major trunk roads, and volume is big, and handling capacity of passengers is big, and travel speed is fast, remote transport of passengers
It is in the zone, to travel that little public transport has two functions one, be convenient to the passenger is delivered to the destination, and the 2nd, be convenient to the big bus that the passenger changes to other direction, make the passenger really accomplish No Transfer Station, transfer fast, bus and bus are accomplished slitless connection.
Three, advantage:
1, significantly reduced the quantity of bus, it is more rationally more balanced that bus is distributed, and avoided repetition and waste.
2, owing to carry out circuit, do not had the signal of turning left of bus, made crossing time of keeping straight on longer, made bus running faster, this also with integrated suites in the major trunk roads crossing do not establish to turn left and match.
3, because 1 or 2 websites are only established in each zone, just can satisfy the demand, significantly reduce the website of big bus, make that the residence time significantly reduces on the road, make remote passenger can arrive the destination more efficiently.
4, owing to carry out little bus slitless connection, can make the passenger can transfer to other big bus very soon.
5, can make the passenger all can walk nearest route anywhere, no longer going a long way unnecessarily more.
6, integrate, we can say this cover system, can make bus, can make the passenger arrive the city fast Anywhere really being quick public transport.
