Description
Technical field
The present invention relates to a kind of method of city intersection electronic program, particularly the method in a kind of intersection electronic program left-hand rotation time track.
Background technology
The world today has entered the electronic information epoch, and society is just with unprecedented speed develop rapidly.The mankind even can take advantage of rocket, moonfall ball, visit Mars.But, form therewith serious contrast, at China and even World Developed Countries, in the face of the world-famous puzzle of urban traffic blocking, but feel simply helpless, get into a difficult position.Block up, become the worry of can't get rid of in numerous cities, and had a strong impact on the development in city and people's life.The inventor recognizes through further investigation the problem of wanting transport solution crowded, must take a three-stage approach:
The first step, first finds the very crux of blocking up.Inventor finds through observational study, and the right-angled intersection in city, on perpendicular, widthwise, generally has 4 groups of fleets to cross at this now, i.e. vertical straight driving team, vertically turn left fleet, laterally keep straight on fleet, the horizontal fleet of turning left.Conventionally adopting at present 4 groups of ways that fleet's samsara is passed through, is generally samsara in 4 minutes.So form each fleet, must wait for 3 minutes at crossing, the situation that but only can pass through one minute.When driving peak period, vehicle increases suddenly, and all intersections of passing through must be waited for 3 minutes again, and car is more, and the time of wait is just longer, so forms chain reaction, causes serious traffic congestion.Seriously hamper the development in city.This is the congenital fault of construction of urban traffic network, causes the very crux of blocking up.This chronic disease is not removed, and other is controlled stifled measure and is all difficult to prove effective.
Second step, the reason that has found traffic congestion chronic disease to be difficult to dissolve: the economic strength in current all cities and scientific and technological level, do not possess the block up condition of chronic disease of radical cure intersection.Its Main Basis is:
First, financial resources are not enough.At present, effecting a radical cure the most effective way of chronic disease of blocking up, is in intersection, generally to set up left-turn flyover, and straightgoing vehicle and left-hand rotation car are taken their own roads, and could fundamentally administer the chronic disease of blocking up.Yet, in a city, set up hundreds of, several thousand dotted left-turn flyovers, be can't bear the heavy load of city, even strong, generally set up left-turn flyover, that will make the human landscape in city be subject to heavy damage.Therefore, it is not yet seen complete grade separation city.
Secondly, current science and technology is limited.The existing scientific and technological level in the world, does not also possess and makes car directly to leap city intersection and condition that the difficult problem that makes to block up is resolved.What city can be done at present is only by building many major trunk roads, quick circuit, subway network, light rail track etc., the transportation network forming, and take the number of shaking to purchase the measures such as car, odd or even number driving day, part section no left turn from administration.But above measure is just alleviated for the moment, block up still.So, the proposition that brainstrust both domestic and external is very helpless decomposition metropolis, set up the stifled scheme of controlling of satellite city.This is costly great engineering, and it is implemented difficulty and well imagines.Therefore fail so far to cause enough attention.
The 3rd step, for the crux of blocking up, looks for another way, and finds and controls stifled invention new approaches.
The above, and the stifled experience of controlling of many decades is known proof in the world, Zhi Duzhi road, walked to be at the end in the past, got into a difficult position.Inventor profoundly experiences and must look for another way, and just likely finds Zhi Duzhi road.So, invented the automatic control time box system of auto-programming has been set in intersection, make fleet and craspedodrome fleet to cross over intersection simultaneously, thereby dissolve or alleviate blocking up of intersection.

The various facilities of described time casing, all set for the running time of the left-hand rotation fleet 5 in intersection, 5a lift-launch, conversion, craspedodrome fleet 3,3a.And the operation of various facilities in time box system all by electronic program auto-controll operation, and by following four lift-launch steps, gradates the time of craspedodrome fleet 3,3a to be built into the left-hand rotation time track serving as a connection:
(1) the master switch K of opening time box system, the time casing demonstration of road A, each program control lamp group links simultaneously.The aobvious green information of information lamp 17,17a of now keeping straight on, is instructed in and in casing, waits the left-hand rotation fleet 5, the 5a that send out, is equipped on the time of craspedodrome fleet 3,3a, crosses over intersection simultaneously, travels and within 26 seconds, arrives left-turning pathways 4,4a place later.This process makes fleet 5,5a to obtain the left-hand rotation time of 26 seconds.Account for 41% left and right of left-hand rotation time.The running time speed of craspedodrome fleet 3,3a is not affected.
(2) casing Limit Control information lamp 1,1a amenable to process are parked in outside casing boundary marker line 15,15a with the red information lamp indication box of 0-26 seconds external restricted driving vehicle 16,16a, wait to send out.The afterbody of fleet 3,3a of now travelling in opposite directions in casing forms time, the space expanding gradually, thereby from left-turning pathways 4,4a, turns left to have created steric requirements for left-hand rotation fleet 5,5a.After this, casing Limit Control information lamp 1,1a, travel and to vehicle, wait to send out place 9 and wait for samsara next time with external each fleet's inlet of green information lamp indication box of 27-63 seconds again.
(3) time that aforementioned left-hand rotation fleet 5,5a carry craspedodrome fleet 3,3a is while arriving left-turning pathways 4,4a, No. 1 double-head arrow left-hand rotation information lamp 2,2a followed the also left back turning in original place in 27-63 seconds mutually with green information lamp indication left-hand rotation fleet 5,5aYi Indian file in advancing, then according to the first order on a right back left side, form 2-3 tunnel craspedodrome columns, in the space of reverse craspedodrome fleet 3,3a afterbody, travel.Arrive behind intersection, according to the indication of crossing right-hand rotation information lamp 12,12a, turn right again, then disappear to intersection.Meanwhile, left-hand rotation fleet 5,5a afterbody still have several cars crossing over crossing center line, and the green information lamp that now crossing No. 2 double-head arrow left-hand rotation information lamps 11,11a show is indicated its direct flicker, and completes left-hand rotation stroke with 3-4 tunnel columns.Be in Midway Island 7 and wait the left-hand rotation cart 6, the 6a that send out, follow and carry out thereafter flicker and complete left-hand rotation stroke.This section of left-hand rotation stroke makes fleet 5,5a to obtain 37 second time, accounts for 58% left and right of whole left-hand rotation times.
(4) aforementioned three lift-launch processes, have made fleet 5,5a to obtain required 63 seconds left-hand rotation running times.Now, according to programming, road A, road B move in turn alternately, and road A time casing disappears, and road B time casing shows, and repeats all programs of road A.And the first bus of each fleet of road B now, the intersection of 50 meters of left and right from start to crossing over, need the time of about 12 seconds, now travel on road A left-hand rotation cart 6, the 6a in its place ahead, if leave several cars, fail left-hand rotation stroke, had 8-10 seconds time to can be used as the time of leading lift-launch.Its lift-launch process is: if road A not yet completes, 4-5 meters, first bus the place ahead that several cars of left-hand rotation and left-hand rotation cart 6,6a are travelling on each fleet of road B, each fleet's first bus of road B travels on intersection following closely, until left-hand rotation cart 6, the 6a of road A disappear to crossing.This is additionally to obtain road A to turn left the time, adds acquired 63 second before this time, obtains altogether the left-hand rotation time of 73 seconds.
Above-mentioned time casing marker line, the position of transport information lamp group can be according to the actual conditions adjustment of road, the programming data of time casing also can be adjusted accordingly according to the number of road vehicle, in addition, the center beacon that indication vehicle is kept straight on also can change to be made as and is located at both sides craspedodrome information lamp is set.
Shown in Fig. 2, it is the structural representation of T-shaped intersection road A, applying the present invention to T-shaped road junction implements as follows, setup times casing on road A only, road B does not need to arrange, and in the centre in road A outside, sets up 18 1 of T-shaped left-turning traffic information lamps, vehicle on indication road B turns left, when each fleet of road A travels 63 seconds according to the indication of multipacket message lamp, road B left-hand rotation fleet travels 40 second time by the indication of T-shaped left-turning traffic information lamp 18, and moves in circles and travel according to this.The wagon flow at this crossing is also significantly improved, and this had improved more than 0.8 times originally.
Below several problems that relevant the present invention need illustrate:
(1) traffic rules are administrative regulations of government administration department set down legally.Therefore, the present invention is observing under prerequisite by statute, a left-hand rotation time track with left-turn flyover function is provided.As for how using left-hand rotation time track, Ze You traffic administrative department makes decision according to responsibility.
(2) described left-hand rotation fleet 5,5a travel in time track, and the speed of its speed need be set according to the width situation of time case road.Having a lot of social connections in road, easily turns left, and speed is fast, otherwise slow.63 second time casing of described example is 8 bursts of tracks, and its width is moderate, and the speed that sets left-hand rotation fleet 5,5a is 4 meter per second left and right.The data of this speed are the road speed gained of 50 meters of width intersections of on-site inspection.The first bus of this crossing craspedodrome fleet, 50 meters of wide crossings from start to crossing over, its time is 12 seconds, divided by 50 meters, equals 4 meter per seconds; Thereafter medium speed is 6 meter per seconds; Become fast 8 meter per seconds (this speed per hour is 29 kilometers/hour); The 4 meter per second jogging speeds that set are that actual motion should be faster than this speed in order to make fleet 5,5a steadily to turn left.
(3) Midway Island 7 is the important component parts in time track, it is that left-hand rotation cart 6,6a(comprise bus and large car) in advancing, enter and wait for the Midway Island 7 of left-hand rotation, make it avoid turning left in narrow location, and under the control of No. 2 double-head arrow left-hand rotation information lamps 11,11a, from Midway Island, 7 directly turn left to travel, and follow in left-hand rotation fleet 5,5a afterbody and complete left-hand rotation stroke.Arranging than being easier to of Midway Island 7, only need move 3-4 meters of left and right a little outward by sidewalk zebra stripes 8 positions of intersection four direction, can form 4 long-pending Midway Islands 7 of 4 * 40 rice and flour, can park 3-4 left-hand rotation carts 6,6a at every turn.All let pass in each two corresponding Midway Islands 7 simultaneously, therefore 6-8 left-hand rotation carts 6,6a can let pass in Midway Island 7 per minute.
(4) described time track is controlled stifledly, and the vehicle flowrate of its intersection only doubles many than originally, have certain limitation.If vehicle flowrate surpasses this limitation, also can produce jam.Comprehensive transportation network construction is also absolutely necessary.
(5) build time track, the seeking time casing road width of, take that to facilitate the left-hand rotation of left-hand rotation car be principle.8 strands of roads more than track are practical, and 6 station tracks and 4 station tracks need to widen transformation, cancel some greenbelts, and the transformation that traffic lights are restricted driving is carried out on some nonmotorized vehicle lanes, sidewalk possibly.Its expense is insignificant with setting up that an overpass bridge compares.
(6) No. 1 double-head arrow left-hand rotation information lamp 2,2a and No. 2 double-head arrow left-hand rotation information lamps 11,11a are set, its objective is that indication left-hand rotation fleet 5,5a can Bian2-3 road, You Yi road column travel, shorten the left-hand rotation time, its outward appearance and shape are set by traffic administrative department.
