Description
Technical field
The invention belongs to intelligent transportation field, and in particular to a kind of traffic administration side for aiding in right-turning vehicles to avoid pedestrian
Method.
Background technology
China newly hands over rule to explicitly point out, and motor vehicle passes through no signal lamp, traffic sign, traffic marking or traffic-police
During the intersection of commander, should slow down, running into when pedestrian passes through crossing should Stop and give way.Right-turning vehicles do not avoid
Pedestrian, belong to unlawful practice, the punishment of 200 yuan and 3 points can be sentenced.From this friendship rule as can be seen that vehicle right lateral need to avoid row
People, the loudspeaker that can't ring are urged and caught pedestrian, can not more turned right by force.
But driver regularly avoids what pedestrian can meet with again when turning right.CCTV reporter is once in Ningbo, north
Did test in capital etc..It was found that within the period of observation, the right-turning vehicles more than 90% during crossing by that will not avoid row
People.Reporter observes the actual conditions for setting right turn signal lamp simultaneously.Reporter has found to set the section of right turn signal lamp, not had substantially
There is a pedestrian and a phenomenon that motor vehicle scrambles for roads.When not excessive right turn signal is red light, even if there is no pedestrian on crossing, right-hand rotation car
Vehicle on road must also wait.So dress right turn signal lamp can more preferably ensure pedestrains safety, but can be to right-turning vehicles
Current rate cause necessarily to influence.
CN206249555U, a kind of pedestrian for being used to reduce traffic accident go across the road caution system, which disclose this
A kind of caution system of kind, including vertical rod, video camera, switch board and words display screen, are characterised by:Zebra stripes go out with road
Floor-lamp is provided between mouthful, is provided with floor-lamp on the outside of zebra stripes corresponding to link entry, circuit part is by graphics processing unit group
Into video camera is connected with the input of graphics processing unit, and graphics processing unit passes through RS485 communication modules and traffic
Traffic controller communicates, and obtains the signal lamp state in all directions of crossing.Pedestrian of the present utility model goes across the road warning
System, realize traffic signal light condition and whether coordinate on zebra stripes with the presence of pedestrian, dodged selectively to put shiny red or yellow
Bright lamp, to remind the motor vehicle that will be travelling through zebra stripes to watch for pedestrians, the security of pedestrians travel's road is effectively guaranteed, can
The generation of traffic accident is effectively reduced, beneficial effect is notable, is suitable for the application of popularization.The technical scheme of the patent is by ground
Flashing lamp is set to remind or warn right-turning vehicles, although this mode low cost, effect do not show：Be not easy by
Identification；The driver not complied with the rules can turn a blind eye to this；Right-turning vehicles driver simply knows that to have pedestrian to pass through but unclear
When Chu pedestrian is by not enough accurately.
The content of the invention
When handling the right of way battle of right-turning vehicles and pedestrian, majority concentrates on to take measures prior art to pedestrian, and
Majority is using gentle " prompting ", " warning ", although this mode can avoid some traffic accidents in terms of pedestrian, effect
It is limited, and have traffic police's reflection, in routine duties, a simple automobile traffic illegal activities are handled, the general used time is not
More than 15 minutes；But an illegal pedestrian or non-motor vehicle driver are punished, must often grind dozens of minutes lips, very
Time-consuming, consumption energy.
It is horizontal based on the current automobile civilization in China, it is necessary to not taken measures by the right-turning vehicles for handing over rule to travel, though
The punishment of increasing amerce deduction of points can be so taken such vehicle at present, but this punishment can not eradicate above-mentioned traffic
Accident, it is therefore necessary to right-turning vehicles are taken measures before accident occurs.The present invention is on the basis of calculating, by road
Face sets the roadblock that can be lifted, and can play a part of forcing if necessary stopping right-turning vehicles, and not delaying, right-turning vehicles conjunction rule are logical
On the premise of row, and then avoid imminent traffic accident.
The present invention provides a kind of following technical scheme, a kind of traffic management method for aiding in right-turning vehicles to avoid pedestrian, bag
Computer Image Processing part and single-chip microcomputer are included, Computer Image Processing part includes computer, taking the photograph towards zebra stripes region
Camera as head and towards runway;Computer is connected by the serial ports of single-chip microcomputer with single-chip microcomputer, and single-chip microcomputer is connect by it
Mouth is connected with roadblock control centre and traffic lights;Described camera is USB camera, and this method step is as follows：
A. right-hand rotation runway is directed at towards the camera of runway, gathers speed, acceleration and automobile and the punching of automobile respectively
The distance between prominent domain information;Towards the camera in zebra stripes region, the speed of travel and figure and features feature of pedestrian are gathered；
The video information gathered in B.A steps reads in image processing system;
C. kinetics equation is utilized, prediction automobile reaches the time of collision domain；
D. judge whether the interval time of automobile arrival collision domain is more than time threshold, if so, performing step (E), otherwise, perform
Step (A);
E. single-chip microcomputer sends a command to roadblock control centre, and roadblock rises, and automobile pause, after pedestrian after, roadblock declines, vapour
Car passes through.
The roadblock control centre includes wireless communication module, for being communicated with each roadblock, display module, for showing
Show the information of each roadblock；The roadblock has unique number, facilitates staff timely and effectively to obtain the related use of roadblock
State and repair message；To be connected in parallel between the roadblock, i.e., in the case of some or the damage of some roadblocks or failure,
Other roadblocks remain to normal startup, used；The road boat includes elevating control module, for controlling rising or falling for roadblock,
Including wireless communication module, for being communicated with roadblock control centre.
Compared with prior art, beneficial effects of the present invention are as follows：
1. algorithm is simple, control is uncomplicated；
2. right-turning vehicles driver is helped to form the civilization custom for avoiding pedestrian；
3. effectively reduce the generation of traffic accident.
