Description
Technical field
The present invention relates to a kind of road traffic flow and dredge technology, be specifically related to a kind of tunnel exit and exit of interchange crosses nearly road traffic delay derivation technology.
Background technology
In recent years, along with the fast development of Chinese national economy, infrastructure construction constantly perfect, Highway Construction Scale achieves the development of great-leap-forward, and its function, status have become the important symbol of modern Economy Development.Interchange is the important component part of speedway, as the hinge in freeway net and node, play a part the conversion magnitude of traffic flow, combing and control wagon flow, exit of interchange safety directly has influence on the layout of grade separation, bit selecting, Traffic flux detection, identifier marking are arranged and the selection of the form of grade separation, also has influence on the capacity and level-of-service of speedway simultaneously.
Along with the formation gradually of China's freeway net and speedway are built in a large number in mountain area, speedway engenders many interchange restricted type outlets.Owing to being subject to the restriction of terrain and its features, geology, main line linear or adjacent grade separation, large bridge, tunnel, service facility etc., the outlet of interchange restricted type has following feature: the restriction being 1. subject to road network structure or route corridor, spacing between interchange or between interchange and the Service Management such as service center, parking lot facility is difficult to the requirement meeting minimum spacing, forms multiple exit of interchange.2. by the restriction of route corridor, mountain area and complicated landform, geological conditions, the spacing that tunnel exit and interchange export is difficult to the requirement meeting standard, specification.3. the restriction by route position, dealings and terrain and its features, geological conditions etc. is subject to, interchange is positioned at the lower position of main line horizontal and longitudinal alignment index, exit position sighting distance is not enough, not easy to identify maybe should not deceleration is rolled away from, there is distributed vehicle and miss outlet and the situation that illegal parking, reversing occurs or just rolls away from from fast lane at shunting nose, easily knock into the back, side impact, hit the accidents such as fixture.4. by the restriction of mountain area MODEL OVER COMPLEX TOPOGRAPHY, speedway is positioned at high embankment roadbed section, larger with the discrepancy in elevation of road intersection: or grade separation installation position is unique, and be in long and narrow landform: or grade separation is situated at the foot of a hill and beside a stream, hypsography is larger, grade separation lays difficulty by standard type, and exit ramp is linear sharply to be changed.
Due to the complexity of driving behavior, Freeway Interchange exit ramp region is a traffic accident flash point, under the outlet of interchange restricted type is in complicated transportation condition and road environment, be more prone to bring out ramp exit accident, be usually expressed as: the vehicle 1. shunted in the affined adjacent interchange region of spacing wants changing Lane at exit ramp, traffic flow presents weaving or the state close to weaving, running velocity is caused to reduce, wagon flow is run disorderly, the conflict of traffic flow and the interference to main line through-traffic stream are caused, cause Small Distance interchange regional traffic chaotic, the speed of service and the traffic capacity reduce and traffic accident increases, become the bottleneck road in freeway net.Meanwhile, between adjacent interchange, spacing is excessively near, and continuous multiple outlet, exists fingerpost and arrange difficulty, and outlet road information is numerous and diverse, and driver differentiates difficulty, thus easily occurs the situation missing outlet.Distance between interchange acceleration lane transition section terminal to adjacent Xiaoshan Airport interchange deceleratuib lane transition section starting point is cultivated less than 500m as Hong Yong Freeway is red, within nearly 3 years, in this region, all kinds of traffic accident more than 600 occurring, is more than 4 times of general road-section average accident rate.2. at tunnel and the affined exit of interchange of interchange spacing, there is show the way advance notice traffic sign placement difficulty and driver and can not identify the problem of fingerpost and outlet in time, easily cause ring road outgoing vehicles to miss outlet, the behavior of illegal parking and reversing occurs and causes traffic accident.As speedway Taizhou, Zhejiang, Taiwan and Wenzhou Duan Wuao Pivot Interchange and Niuguantou Tunnel hypotelorism, cause outgoing vehicles to miss export situation to happen occasionally, the behavior of illegal parking and reversing happens occasionally, in 17 months of statistics, there are 37 traffic accidents altogether in this outlet section, cause many people casualties, have a strong impact on the safety of this grade separation Hangzhou outlet.3. when the outlet of interchange main line is positioned at circular curve second half section or convex vertical curve second half section, exit position sighting distance is not enough or not easy to identify, cause ring road outgoing vehicles to miss outlet and illegal parking and reversing occur, or racing steering wheel, there is the accident with kerb lane through vehicles side collision, these accidents are all can not effectively utilize length of deceleration lane by driver, can not effectively controlling party to causing.4. ramp exit is positioned at long and steep downgrade section, and vehicle speed of a motor vehicle in descending process is higher, easily occurs missing outlet or shunting nose accident in collision.From above-mentioned analysis, the outlet of interchange restricted type generally has fingerpost and exit of interchange is not easy to identify, existing outgoing vehicles miss outlet or vehicle split point rapidly changing Lane roll the problem crashed away from, more have near shunting nose because vehicle deceleration is not as good as colliding shunting nose portion guardrail or occurring overturn accident, therefore, ensure interchange restricted type exit, become road safety problem demanding prompt solution.Less owing to there is the outlet of interchange restricted type before China, its traffic accident does not also cause the concern of numerous department, also less to its systematic Study, system is not had to propose safety precautions yet, but the traffic accident occurred in restricted type outlet in recent years gets more and more, system research is carried out to its safety, stereo region traffic accident can be effectively reduced.
For ensureing the safety of interchange restricted type outlet, should take in from the source of ramp exit bit selecting, also will adopt reasonably outlet traffic flow derivation technology, induction traffic flow in time rolls main line away from safely.Therefore, scheme provided by the invention is by the principle of application Road and Traffic Engineering, adopt theory analysis and field investigation, mathematic statistics and numerical analysis, the research method of experiment, and in conjunction with the analysis of driving behavior psychology and ergonomics in safety, to restricted type interchange outlet criterion, the safe design that technology and end are derived in outlet traffic flow carries out system research, for reducing the accident rate of restricted type interchange outlet, improve the safety of speedway interchange, improve road passage capability, service levels etc. provide technical support.

Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
When tunnel exit and exit of interchange spacing are less than spacing constraint, for newly built tunnels, tunnel can be widened and add lane auxiliary, and lane auxiliary is set by 600m length requirement before split point; When length of tunnel is shorter, whole tunnel can be widened lane auxiliary is set, and strengthen the setting of traffic sign, graticule before split point before tunnel portal or in tunnel, remind in time and need driver's changing Lane of outlet to outside lane auxiliary; To built speedway, widen tunnel at need, the setting of traffic sign and floor line should be strengthened before tunnel portal and in tunnel.
(1) traffic sign is arranged.
When tunnel exit and interchange exit separation are less than interval constraint type condition, the setting of traffic sign should be done following adjustment and strengthen, and will roll wagon flow away from imports to exit ramp in time, meets safe driving requirement:
1. 2km, 1km and 500m advance exit sign is set under conditions permit, but advance exit sign and outlet series mark should shift out tunnel road within the scope of 100 ~ 200m, distance adopts the rear numerical value of adjustment, otherwise strictly should prove cancellation 2km advance exit sign, and other marks must be arranged.When advance exit sign is arranged in tunnel, hang on top, tunnel, adopt brightness uniformity and the internally illuminated sign of not dazzle.
2. when grade separation deceleratuib lane starting point is positioned at tunnel or tunnel exit end immediately interchange deceleratuib lane, advance exit sign should be strengthened arrange in tunnel, as shown in Figure 1 apart from shown in front reference point 350m, Fig. 2 apart from shown in shown in front reference point 250m, Fig. 3 apart from front reference point 150m.Arrange in the front appropriate location of tunnel portal point to each track place, Directional Sign, adopt gantry type or supporting way, as shown in Figure 4; When advance exit sign is positioned at outside tunnel portal, can not be overlapping with the traffic sign of tunnel portal.
3., when exit lane is positioned at tunnel, can variable information Information sign be set in tunnel.Be arranged at the changeable-message sign in tunnel, for driver provides road information, and when to meet with a street accident or block up etc. special circumstances time, show corresponding prompt text, changeable-message sign hangs on top, tunnel, as shown in Figure 5.
4. traffic flow should be made before tunnel exit to export to kerb lane, strengthen the setting of advance exit sign, the median strip apart from certain position before reference point arrange advance notice exit direction, as shown in Figure 6, Figure 7.
5. be arranged at the advance exit sign in tunnel, impact should do not had on ventilation, monitoring preparation, and the adjustment that space of a whole page content can be suitable.The specification of word and pattern suitably can reduce according to the requirement of track clearance is overall, but maximumly can not be reduced to 50% of normal specifications.Advance exit sign after reduction must arrange brightness uniformity and the interior lighting of not dazzle.
(2) graticule and ground word marking is strengthened.
Tunnel exit and exit of interchange spacing cross shortcut section, except the graticule pressing normal requirement, should arrange ground word marking between tunnel exit and exit of interchange, control the vehicle of point flow path direction, to strengthen the induction of outgoing vehicles.Exit of interchange is positioned at outside tunnel exit, but distance is very near, or exit of interchange position is positioned at tunnel, arranges ground word marking and guiding arrow, will export traffic flow guidance to kerb lane, and generally arrange three groups, shown in Fig. 8 before tunnel portal.Before tunnel portal at least between 150m to interchange outlet manifold nose between track dotted line be transformed to solid line, forbid that driver is in tunnel and the changing Lane of exit.
Tunnel exit and exit of interchange spacing cross shortcut section, when adding lane auxiliary in tunnel, requiring to arrange according to Fig. 8 before tunnel portal, canalization leading line should be set in tunnel between lane auxiliary and direct lane simultaneously, leading line and word marking is added, as shown in Figure 9 on ground.
(3) lighting installation is set up
Tunnel is the section that in approach system, operating environment is special, has important impact to traffic safety, is two kinds of different operating environments, often becomes accident set mid point before and after tunnel exit.Mostly outlet accident is one of tunnel traffic accident large feature, especially crosses shortcut section at tunnel exit and exit of interchange spacing, and its main cause is that the vision of tunnel exit driver exists " bright ", " secretly " adjustment.At night, vehicle rolls away from from the good tunnel of light, and when tunnel exit light is poor, the eyes due to people have little time the unexpected change adapting to light, in the sensation that the tunnel exit place that light is very dark is the same just like cave, black hole, become " black-hole effect ".When producing " black-hole effect ", driver cannot see obstruction above clearly and even can disorient in the short time.
Shortcut section is crossed at tunnel exit and exit of interchange spacing, improve tunnel exit illumination and Driver Vision condition, effectively traffic flow can be exported to exit ramp at night, reduce the probability missing outlet, meanwhile, tunnel exit and exit of interchange spacing cross shortcut section exit of interchange advance notice mark should be high-visible, correct advance notice driver road ahead information, traffic sign should adopt the reflective membrane that reflex reflection performance is good or the mark adopting active reflective, to improve night-mark(ing) identification.
In addition, the present situation occurred frequently according to interchange restricted type exit ramp accident, should strengthen in main line restricted type, interval constraint type exit of interchange ring road end the traffic safety facilities that bumper, deceleration facilities, inducing installation etc. are set, occur with the order of severity or minimizing accident that reduce traffic accident.
1, bumper design.
" Freeway Traffic Engineering and equipment along road design general specification " (JT G D80-2006) points out: the end of guardrail of speedway main line shunting end, ramp exit should arrange bumper.Bumper makes vehicle safety by absorbing vehicle collision energy, and make vehicle change travel direction avoid occupant to be subject to the facility of grievous injury, its major function is the collision energy absorbing vehicle, belong in some sense " flexible impact ", reduce severity of injuries, play warning and the effect of induction pilot's line of vision by its surface color and graphical symbol on the other hand.
The accident that shunting nose head is hit in the outlet of interchange restricted type is more, and vehicle collision shunting nose head easily causes vehicle to damage and casualties, therefore, and should the order of severity that occurs of reduction accident as far as possible when adopting passive preventive action.At restricted type outlet manifold nose head, should bumper be set.
Research shows that minibus head-on crash result is: collision guardrail board, and termination and collision fragment can not invade interior; Vehicular occupant risk is that car body three direction peak accelerations (10ms average) are all less than 20g.Side collision result is: guardrail board termination and collision fragment can not invade interior; Guide strip serves good guide effect, roll that angle is less than collision angle away from 60% of vehicle; Car body three direction peak accelerations (10ms average) are all less than 20g; Resistance phenomenon of stumbling is there is not in vehicle at bumper and end of guardrail junction.Bumper can effectively protect ring road end shunting nose head, can not affect road clearance.
2, deceleration facilities.
Analysis constraint type cause of accident can be trailed collision and hit fixture accident and mostly be caused because speed is too high, and therefore, interchange restricted type exit region should strengthen the setting of deceleration facilities.
Most of accident of exit ramp and speed have direct or indirect relation, and the design speed due to ring road is general all compared with low more than the 20Km/h of the design speed of main line, is therefore conducive to the control of outlet end Main Line Speed shunting of slowing down.Can point flow valuve smoothly in order to realize that grade separation restricted type outlet car speed is reduced to, mainly through arranging speed(-)limit sign, illusion graticule, concussion graticule, speed reduction marking uniform velocity control measure also can be set simultaneously.The comprehensive use of these engineering measures can be reminded, force driver to be slowed down, and controls to have certain effect to the restricted type outlet speed of a motor vehicle.
Visual illusion graticule can reduce in the application of outlet end the accident caused because speed is too high, visual sense speed reducing graticule uses traffic engineering and traffic psychology principle, utilize the longitudinal deceleration graticule being arranged on track edge line, to the visual effect that lane for driver narrows, remind driver's slow down, drive with caution; Also pentagon three dimensional designs pattern can be adopted, centre is executed and is drawn yellow, blue, white two kinds of colors, it is a kind of graticule of special tool intense, easily cause the vision of driver, driver can make psychoreaction and defence to it psychologically, and driver is wrapped with important traffic accident the easy speed of restricted type outlet end is too high, is reached that to reduce vehicle too high in tip speed by vision graticule, branch to exit ramp smoothly, as shown in Figure 10.Effect for speed reduction marking does not also have clear and definite achievement in research now, shows: driver is familiar with speed reduction marking according to investigation, and is ready to take deceleration measure.Restricted type outlet end is generally easy due to speed too high collision shunting nose head or miss outlet, therefore, controls car speed by graticule, has larger effect to distributed vehicle safety traffic.
3, inducing installation.
Restricted type outlet end inducing installation refers to that induction driver rolls the safety device as ring road away from end setting for pointing out driver Way out.Installing solar energy reflector on ground, ramp exit place, guardrails of both sides column is arranged and installs solar LED clearance light, strengthen the condition of road surface of exit ramp, play sight line inducing effect to human pilot, there is traffic accident in prevention.
Although the present invention discloses as above with preferred embodiment; so itself and be not used to limit the present invention, any those skilled in the art, without departing from the spirit and scope of the present invention; when doing a little amendment and perfect, therefore protection scope of the present invention is when being as the criterion of defining with claims.
