Description
Technical field
The invention belongs to traffic safety technology and intelligent transportation application fields more particularly to a kind of construction area traffic intelligent to draw
Guiding systems and method.
Background technology
In recent years, China's highway has come into reorganization and expansion, maintenance and the newly-built stage developed simultaneously.Highway changes expansion
When building and conserving, especially under the traffic organization being open to traffic in construction, interference will necessarily be generated to original road traffic flow,
Influence normal driving.It is mainly presented with：Vehicle needs completion to import, collaborate and the actions such as shunting pass through construction area, meeting
Appearance vehicle interflow and lane change time shorten, and environment is disorderly, and speed difference is larger, sudden to conflict phenomena such as more；Reorganization and expansion
When construction, interference of the trackside construction to original road normal traffic flow；Road caused by trackside clear space and sighting distance deficiency
Ability decline etc..Number of track-lines, Vehicle Speed, the road (including intercommunication, bridge etc.) of original highway are linear, laterally dry
Disturbing etc., which influences coefficient, occurs significant changes.
Road traffic system is a dynamical system being made of all elements such as people, vehicle, road and environment, most important factor
It is people, the vehicle action of all is all manipulated by people, and people needs the guiding of necessary basis information, driver to need during the motion
External traffic environmental information is obtained to be judged to manipulate.In this system, any factor it is unreliable, uneven,
Shakiness, which is established a capital, may lead to various conflicts and contradiction, to cause traffic accident.Construction area road environment is complicated, with wrap
Road differs widely, if lacking relevant information guiding, it (stress refers to various stressors that can cause driver's response
Caused individual nonspecific reaction, including physiology and psychoreaction), when necessary visual cues missing (is not known how such as
Deng) or unfavorable response is (such as：It is nervous, frightened) when generating, driver's " perception-judgement-decision-operation " may go out
Existing deviation is even entirely ineffective, will will appear improper driving behavior at this time, and then increase traffic risk, and induce traffic accident.According to
The 2%-3% of the total traffic accident of statistical analysis Work sectors traffic accident occupied road, it is higher than normal section by 21.5%, wherein injuring
17.3% and 23.8% more than accident and the normal section of non-injury accident ratio.In addition, it is worth noting that, according to United States highways
The report 627 of joint study tissue ---《Daytime and the area's Evaluation of Traffic Safety that carries on construction work at night》(Traffic Safety
Evaluation of Nighttime and Daytime Work Zones) 2000~2005 years high speeds in the New York that is provided
Statistics of traffic accidents in construction of the highway area, the ratio that death by accident occurs for work zone night are higher than daytime.
Just lacks information since current construction area road compares and guide, therefore the present invention is by the information guidance facility of design,
To carrying out information compensation by the driver of construction area road, to driver's correct guidance, reduces erroneous judgement or thing occurs for mistake
Therefore possibility.The present invention is reminded and is guided by two aspects:1, real-time collecting construction area vehicle dynamic micro-data is right
After data are further analyzed, current optimal guiding control strategy is obtained based on algorithm, and carry out by variable message board
It reminds.The effect that the boot policy can be optimal according to varying environment.Meanwhile continuous many places variable message board provides guiding letter
Breath, it is ensured that strategy is effective to be implemented, and the doubt of driver is reduced.2, real-time collecting construction area vehicle dynamic micro-data,
After data are further analyzed, the safe condition of current region is obtained based on algorithm, and be arranged properly according to safe condition
Intellectual inducing lamp.The intellectual inducing lamp is in the nature edge rate graticule.It can be lured according to current security situation by controlling to shine
The number and form of leading lights reach the reduction of speed effect of suitable present case.Meanwhile traditional edge rate graticule is compared, the present invention
By the preferable yellow LED lamp of penetrability, along construction area can passing road both sides lay, in this way can be bright to driver under night
True road profile information improves safety.
