Description
Technical field
The invention belongs to urban traffic road management and the technical field controlled, relate to integrative design intersection, the field of ITS intelligent transportation system and safety traffic theory, be related specifically to the technical method that section and intersection signal link.
Background technology
Wang Xueyong systematically analyzes cross-road passages for pedestrians about " pedestrian secondary crosses street traffic organization method and applied research ", the problem of signal control and Delay Evaluation, Li Na solves the signal timing dial problem of section cooperation control about " section pedestrian's street crossing signal and intersection signal cooperation control are studied "; But existing research mainly focuses on intersection, the signal of section controls often to adopt the pattern simultaneously increasing motor vehicle and walker signal lamp in the road, provides facility to increase vehicle delay for walking.The present invention on this basis, makes full use of the road idle gap time, proposes and does not affect premised on main body vehicle flowrate, and the crossing street twice safety installations construction only adopting pedestrian signal to control in section, mainly instructs the control of safe isolation guardrail.
Summary of the invention
The technical problem to be solved in the present invention has long section (as accompanying drawing 3) between the crossing of left-hand rotation dedicated phase for upstream and downstream, under the prerequisite not affecting main body wagon flow and guarantee pedestrains safety, the pedestrian secondary that signalization controls in the middle of long section crosses street guardrail facility, reduces the distance that detours of the pedestrian's street crossing in the middle of long section.Wherein, pedestrian secondary crosses the opening and closing signal time of street guardrail and signal coordinated control is carried out in upstream and downstream crossing, and carries out time complexity curve according to existing road conditions, pedestrian's condition, and the opening and closing pattern of guardrail is relevant to upstream and downstream signal phase.
Technical scheme of the present invention is:
When thing upstream crossing left-hand rotation dedicated phase is let pass (second phase), east exit road, crossing, upstream does not have other vehicle pass-throughs except vehicle of turning right on a small quantity.Utilize this neutral, under the prerequisite not affecting vehicle body wagon flow, pedestrian can utilize underpass to arrive safely safety island, and waits for street at safety island.When downstream intersection East and West direction left-hand rotation dedicated phase is let pass, the downstream intersection stomatodeum that exports to the west does not have other vehicle pass-throughs except vehicle of turning right on a small quantity, pedestrian can utilize this neutral to arrive at across the street by safety island, completes street behavior (accompanying drawing 4 is shown in by concrete schematic diagram).
Wherein open and close type pedestrian's street crossing isolation guardrail concrete structure comprises pedestrian's street crossing request button, pedestrian's pilot lamp, independent opening and closing guardrail, safety island four parts.Pressed street request button when pedestrian You Guo street demand, system can engage upstream and downstream crossing timing scheme, determines the display of pedestrian's pilot lamp and the unlatching of independent opening and closing guardrail.Safety island is set up in open and close type pedestrian isolation guardrail guardrail inside.As follows by pedestrian's pilot lamp step:
(1) pedestrian's street crossing signal is configured
According to the scheme of upstream and downstream Intersections timing, tentatively determine pedestrian's street crossing green time theoretical assessment according to signalized intersections timing theory
Pedestrian's red time
Pedestrian's green time
In formula:
T
gfor motor vehicle can pass through phase time, T
rfor motor vehicle impassability phase time, S is the distance of walkway to upstream, road cross junction, v
pfor pedestrian crossing speed, v
vfor motor vehicle speed degree, b is sidewalk width, and l is motor-driven vehicle commander, and d is single lane width.
After determining pedestrian's street crossing green time, according to road basic condition (comprising link length width, surface evenness, road gradient, motor vehicle flow, motor vehicle density, motor-driven vehicle going behavior) and pedestrian's feature (comprising pedestrian's quantity, age distribution, sex, health degree), actual correction is carried out to theoretical assessment again, obtain pedestrian's street crossing signal timing plan.
(2) guardrail facility is designed
(2.1) design of safety island
Open and close type pedestrian's street crossing isolation guardrail inside is safety island, and the quantity holding pedestrian determines according to its size, is positioned at center line of road place; Safety island length is according to the design of urban road facility related specifications, and width is minimum for criterion to take track area, and reduce the impact on motor vehicle, concrete width is determined by actual road conditions;
By to the research of existing safety island and improvement, adopt the model that induction type combines with boat form.
General when road width is limited, induction type safety island can be selected, can be the staying space that pedestrian provides larger; If driver's sight line is not blocked in the design of safety island on this basis, boat form safety island can be selected, can be pedestrian and safety guarantee is provided.
(2.2) opening and closing pattern
According to pedestrian's street crossing signal, the opening and closing pattern controlling guardrail instructed the orderly street excessively of pedestrian; Be respectively the guardrail of independent opening and closing in open and close type pedestrian's street crossing isolation guardrail both direction, and be provided with corresponding pedestrian's street crossing pilot lamp; According to the time that step (1) is arranged, both sides pedestrian's street crossing carries out in strict accordance with the instruction of pilot lamp, and when green light lights, the countdown of pedestrian's street crossing pilot lamp starts, and guardrail is opened, and pedestrian's street crossing enters safety island; When green light closes to an end, the pedestrian that pilot lamp prompting does not enter road waits in curbside; When green light countdown terminates, red light lights, and guardrail cuts out, and no longer allows pedestrian to enter safety island, fails the pedestrian in street to wait in roadside and next allowed the signal in street to pass through again;
Guardrail opening and closing divides three kinds of modes: 1) guardrails of both sides is opened simultaneously, allows pedestrian once to cross street; 2) side rail is opened, and a side rail is closed, and the side road allowing pedestrians travel to open guardrail enters safety island and waits for that opposite side guardrail is opened and pass through opposite side road again; 3) guardrails of both sides is closed simultaneously, does not allow pedestrian's street crossing;
(2.2.1) pedestrian once crosses street pattern
Pedestrian gather some and You Guo street demand time, if there is wagon flow space in corresponding one-sided road, signal is green light, then the guardrail of corresponding side is opened, and give display lamp prompting " can pass through " and green time countdown to pedestrian, pedestrian pass through within the green light stipulated time one-way road enter safety island simultaneously other direction just there is wagon flow space, pedestrian signal is green light, and duration meets pedestrian passes through road required time completely, allow pedestrian not stop in safety island and directly completed once street;
(2.2.2) pedestrian secondary crosses street pattern
Pedestrian gather some and You Guo street demand time, corresponding one-sided road signal is green, clearance opened by guardrail, and pedestrians travel's road enters safety island, and other direction road has continuous wagon flow, corresponding pedestrian signal is red light, require that pedestrian stops waits in safety island, and show stand-by period countdown, until opposite side signal is green light by pilot lamp, let pass at the corresponding guardrail of opening and closing and pass through, complete pedestrian secondary and cross street.
Effect of the present invention and benefit are:
Under the signal coordinated signals described by Li Na, preferably can complete the object of pedestrian's street crossing, but the design of signal lamp still can there is no small impact to the delay of motor vehicle.Our scheme is by controlling safety island isolation guardrail, and the behavior of restriction pedestrian's street crossing, thus cancellation motor vehicle signal lamp, only arrange pedestrian's street crossing control signal, this is a very large strategic structural.Operationally, pedestrian passes through according to Signalized control, and motor vehicle is taked to dodge principle, is the blank pattern of prevailing traffic mode, and needing increases new traffic ordinance regulation.By Traffic Simulation Evaluation, this scheme greatly reduces the delay time at stop of main body wagon flow, and can solve pedestrian's street crossing demand in the middle of long section to a certain extent, and the time, economic benefit was much larger than signalized and unsignalized intersections.Specifically:
1. space utilization efficiently: at the midblock of major urban arterial highway, offer pedestrian's street crossing passage.By appropriate design and the traffic organization optimization of function path, giving manner of walking more while multichannel power, still ensureing the demand of major urban arterial highway area motor vehicle right of way, path resource having been reallocated, high-efficiency and economic.
2. the city plate that can reach: major urban arterial highway is connected to difference in functionality plate in city usually, how rational section passage, transfer transmission and the accessibility of the stream of people and logistics between each functional areas can be realized, promote the integration development in city, arouse its life and vigor.
3. people's car pattern of mutual benefit: signal divider can instruct pedestrian's street crossing, thus reduce pedestrian to the impact of wagon flow, make road smooth and easy; The opening and closing of signal divider, to while pedestrian's street crossing chance, it also avoid the phenomenon appearance that pedestrian arbitrarily passes through, ensures autos only.Normal on-mode can be taked under special circumstances to ensure pedestrian's traffic requirement.Setting up of signal divider makes pedestrian and wagon flow mutual reciprocity and mutual benefit, embodies the theory of " harmonious traffic ".
4. application prospect: China is in Rapid development stage, the demand of traffic is increasing, and people's car contradiction is also more serious, especially major urban arterial highway area, vehicle flowrate, pedestrian's amount all constantly increases, need to improve road utilization rate energetically, so our design has very large use value.Corresponding safety island guardrail opening and closing signal is designed to instruct pedestrian's street crossing by the timing of upstream and downstream crossing, concrete section.Meanwhile, such traffic design management and organization optimization, contain the design concept of complete street, more embody the humanistic care in a city, people-oriented, and the distribution and Appropriate application of right of way more embody the central characteristics of a smart city, is the traffic new image in a city.

Embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with technical scheme, and simulate working of an invention effect.
We adopt the stand-by period the longest situation of pedestrian's street crossing to assess the effect of Guardrail design.
1. basic road conditions design
According to documents such as the U.S. " HCM HCM2000 " " urban highway traffic facilities design specification GB50688-2011 " " urban road intersection design discipline CJJ152-2010 " " urban road engineering design specifications CJJ37-2012 ", and based on one section, Zhongshan Road, Dalian blue mud hollow CBD area, design and simulation road conditions.East-west is trunk roads, two-way ten two lane highways, overall length 550m.South-north direction is branch road, two-way eight tracks.The wide 3.5m in bicycle road, thing trunk roads beam overall 42m, the unidirectional 21m that has a lot of social connections; North and south branch road beam overall 28m, the unidirectional 14m that has a lot of social connections.Trunk roads upstream and downstream sets up two standard cross junctions separately, and consider worst condition, we devise following two kinds of phasing schemes:
Scheme one: it is left that crossing, upstream adopts two phase to prohibit, and downstream is four phase places.
Scheme two: consider more generalized case, upstream and downstream crossing is common four phase places.
2. motor vehicle flow design:
According to " urban road design criterion " road passage capability related request, obtain road actual capacity numerical value.
Compare correction with Daliang City's blue mud hollow shopping centre measured data again, obtain vehicle flowrate data.The flow value obtaining turning of motor vehicle and craspedodrome with motor turning probability is distributed by track.Wherein, four phase place six-lanes: turn left: keep straight on: right-hand rotation=2:3:1; Four phase place Four-Lane Roads: turn left: keep straight on: right-hand rotation=1:2:1; Two phase six-lane: keep straight on: right-hand rotation=11:1; Two phase Four-Lane Road: keep straight on: right-hand rotation=7:1.(see the following form one, table two)
The two-way eight lane flow amount data (pcu/h) of table one
The two-way ten two lane highways vehicle flowrate data (pcu/h) of table two
3. safety island and pedestrian measure design
For the hollow bridge Zhongshan Road of Dalian blue mud, road stage casing double amber lines spacing is 0.8m, the long 6m of our design safety island main bodys, wide 1m, area 6 ㎡.Each pedestrian's area occupied gets 0.25 ㎡/people, then can simultaneously galleryful 24 people under safety island full load condition, then one-sided seating capacity is 12 people.In worst condition, pedestrian need wait in safety island, and in the signal period, the one-sided road pedestrian traffic capacity is 12 people, then one-sided pedestrian's flow per hour is 332 people/h, and it is better that degree of fitting is investigated in data and current demand.
4. crossing, the design of safety island guardrail signal lamp
According to related specifications and investigational data on the spot, the intersection signal cycle, total duration was set to 130s, and according to motor vehicle flow, the index Design out of phase times such as delay.Because we consider pedestrian's street crossing worst condition, after safety island is arrived in pedestrian's unidirectional mistake street, other direction wagon flow arrives safe distance just, and pedestrian needs resident at safety island, until this direction Clear Field Vehicle crosses zebra crossing.In this situation, pedestrian's street crossing is the longest for time delay.Calculate the pedestrian signal time according to theoretical model, then go out satisfactory multiphase traffic time allocation according to upstream and downstream crossing timing design.Concrete signal phase relation is shown in accompanying drawing 5, accompanying drawing 6).
5. Positive simulation results and evaluation
Our goal in research is that pedestrian's street crossing does not affect major trunk roads craspedodrome motor vehicle, requirement is reached by safe distance and signal timing dial, thus guardrail instructs pedestrian's street crossing can't occasion a delay to straightgoing vehicle and left-hand rotation car, but occasions a delay to the upstream and downstream crossing vehicle entering trunk roads of turning right.Because at pedestrian's street crossing place, we are provided with crossing, according to traffic law, at walkway place, motor vehicle need dodge pedestrian, certainly will occasion a delay to right-hand rotation car.Therefore, we using to the delay of right-hand rotation car as motor vehicle evaluation index.Simulated by VISSIM software emulation, we obtain the vehicle delay that the right-hand rotation of upstream and downstream cross junction enters major trunk roads.(see the following form three, table four)
Table three upstream two phase, downstream four phase place
Table four upstream four phase place, downstream four phase place
Calculated by data, scheme one right turning vehicle is incured loss through delay for 4.3s, 7.8s, and scheme two right turning vehicle is incured loss through delay for 1.3s, 1.8s.For the crossing of common upstream and downstream four phase place, right-hand rotation car is incured loss through delay very little.For pedestrian, originally only obviously longer from intersecting make a slip of the tongue time in street, and road stage casing provided street chance to pedestrian, decrease crossing street pedestrian amount, alleviate people from crossing car contradiction, be conducive to the street efficiency excessively improving pedestrian and motor vehicle, alleviate the traffic pressure in CBD area, city.(simulated effect figure is shown in accompanying drawing 7)
Simulated roadway stage casing pedestrian secondary crosses street, the manner of walking that safety can reach more makes the regions module of isolation relatively originally organically connect, the increase of stream of people's logistics promotes the economic development of CBD commercial circle, the reasonable efficiency utilization of path space, the realization of road complete function, these are all conducive to heavily calling out CBD life and vigor.
