Description
Technical field
The invention belongs to technical field of traffic signal control, relate to a kind of crossing mark identification device and using method thereof and application, particularly relate to a kind of road junction vehicle guide sign device for city blocked road and control method thereof and application.
Background technology
The sailing mouth into and roll mouth away from and can be divided into two kinds, a kind of sailing into or rolling away from by fixture guided vehicle of blocked road, such as, by guardrail or enclose road brick, another kind is then only rule by ground and is guided.No matter the former or the latter, cannot exchange as entrance or outlet.That is, outlet is outlet forever, and entrance is entrance forever.
A kind of condition of road surface of frequent appearance is, such as, in the porch of a closed section, just in traffic congestion on this closed section, and vehicle outside it on adjacent bypass is considerably less.Because this crossing is for sailing mouth into, so the car on this closed section can not roll this closed section away from, entering on above-mentioned adjacent bypass, causing the serious waste of path resource.Otherwise, sometimes in exit, very unimpeded on closed section, and bypass is had traffic congestion, but the vehicle on closed section can not roll away from from exit.
And in actual traffic application, it controls and confinement problems existing for elicitation effect for above-mentioned ring road entrance or its changeless id signal of ramp exit, settling mode many employings ring road mouth control mode conventional at present, it is by multiple ramp metering rate algorithm, as timing controlled, demand-capacity difference controls, occupation rate control or ALINEA control algolithm etc., although these control methods achieve certain control effects, but the interrupted traffic flow situation of the large discharge for China's city expressway ring road entrance and ramp exit, there is great limitation, in addition, on signal time distributing conception, the many employings of this kind of ring road mouth control mode are at regular time and quantity by the method for smallest number vehicle, although the impact to the main road magnitude of traffic flow farthest can be reduced like this, but but considerably increase the stop frequency of vehicle, even and adopt this ring road mouth control mode to reach capacity flow, also cannot meet the magnitude of traffic flow demand of China's city expressway ring road mouth.
Application number is 201010236959.7, application publication number is CN101908280A, name is called that the Chinese invention patent application of " control method of signal light at ring road junction of express way and device " discloses a kind of device of signal light at ring road junction of express way, it signal lamp comprised for controlling bypass keeps the first control module of the state that gives a green light when bypass is in congestion status, for controlling the second control module that described signal lamp keeps when ring road is in congestion status sending out a warning, for judging whether bypass is in the first judge module of congestion status, bypass for judging according to the first judge module controls the 3rd control module that described signal lamp keeps giving a green light when being in congestion status, and for according to the first judge module half section of bypass out be not in congestion status time control the 4th control module that described signal lamp keeps sending out a warning, also disclose the control method corresponding to its above-mentioned functions of modules of the device of above-mentioned signal light at ring road junction of express way simultaneously, the control method of this signal light at ring road junction of express way and device, it is by when learning that bypass is in congestion status, adopt the mode of time signal lamp being extended to green light, reduce the vehicle aggregate amount on bypass to a certain extent, then again by when learning that ring road is in congestion status, adopting the mode of time signal lamp being extended to green light, reducing the traffic pressure of main road to a certain extent, although it can to solve on through street ring road mouth place vehicle congestion to a certain extent even by the problem blocked completely, thus prevent through street from the phenomenon of overall paralysis of blocking up occurring to a certain extent, but because it is by adopting the signal designation mode of erection traffic lights, for vehicle drivers, need to note observing the instruction situation of traffic lights at ring road mouth, thus disperseed human pilot to the notice of road conditions and adjacent vehicle situation, in addition, again because erection traffic lights can produce certain taking to the place at ring road mouth place, make natively likely to produce the ring road port area of blocking up more narrow, in addition, again because ring road mouth is vehicle changes travel direction, sail the fork in another section into, traffic lights are set herein and also there is the possibility that vehicle swipes to it, buried hidden danger to a certain degree for traffic hazard, most importantly, adopt and need in this way to arrange traffic light respectively at ring road entrance and ramp exit place, and in vehicle travel process, there will be the generation of some ring road porch to block up, and simultaneously ramp exit place without vehicle pass-through, or the generation of some ramp exit place is blocked up, and simultaneously ring road porch without the phenomenon of vehicle pass-through, therefore the waste in ring road mouth and the traffic light utilization of resources is then caused, namely the cost that through street is built is added, again reduce the efficiency of the Expressway Traffic utilization of resources, be difficult to the reliable wagon flow also effectively controlling and dredge fast road ramp mouth place.
Application number is 200810039792.8, application publication number is CN101299298A, name is called that the Chinese invention patent application of " a kind of road self-adapting entrance ramp afflux control equipment and method " discloses one and comprises controller of ramp afflux, DETECTION OF TRAFFIC PARAMETERS device, ring road imports signal lamp, ring road imports count-down device, advices plate and current lamp, and for the road self-adapting entrance ramp afflux control equipment and the method that regulate the Entrance ramp of highway or urban express way to import flow, it reads flow with certain cycle from DETECTION OF TRAFFIC PARAMETERS device by controller of ramp afflux, the traffic parameter such as speed and occupation rate, and obtain signal time distributing conception by calling EXPAlinea control algolithm, then control local device ring road according to signal time distributing conception and import signal lamp, ring road imports timer and ring road mouth and to pass through lamp and advices plate, although it can solve the control problem of the interrupted traffic flow at ring road porch large discharge to a certain extent, but because it is utilize the signal designation mode at ring road mouth place erection traffic lights equally, so its exist equally above-mentioned human pilot notice to be had an impact, having an impact to ring road mouth place's road conditions and the situation of occupation of land, and cause the defect of the waste in ring road mouth and the traffic light utilization of resources, be difficult to reliable equally and effectively the wagon flow at fast road ramp mouth place managed, controls and dredged.
On the whole, the road junction place of more existing blocked roads, especially main road and bypass are in the road junction place of the city blocked road of a surface level, its signal indicating device and control method thereof mostly are the signal designation mode adopted at road junction place erection traffic lights, exist more and above-mentioned human pilot notice to be had an impact, to road junction place road conditions with take up an area the having an impact of situation, and cause the defect of the waste in ring road mouth and the traffic light utilization of resources, thus cause the increase of through street construction cost and the reduction of the Expressway Traffic level of resources utilization, be difficult to the wagon flow at the road junction place reliably also effectively controlling and dredge blocked road, the road junction place of blocked road cannot be met, especially the actual requirement of the road junction place traffic administration of through street is closed in city.
