Description
Technical field
The present invention relates to field of traffic safety, especially a kind of multilane tunnel wagon flow regulation side based on traffic monitoring
Method.
Background technique
With the raising of road construction technical level, tunnel is also quickly sent out as a kind of important feature of highway communication
Exhibition, ends the statistics in the end of the year in 2013, and China has built 11359 vcehicular tunnels, and 9606 kilometers of overall length.It is built in vcehicular tunnel
While popularization, tunnel traffic safety also becomes important topic concerned by people.Tunnel is a kind of to be embedded in surface layer
Transport structure, thus the people of outside is not easy to know the traffic state in tunnel, so will appear sometimes multilane tunnel unavoidably
In the unexpected vehicle density in certain lane become larger or become smaller, the lane of wagon flow is distributed serious unbalance.The appearance of this situation can allow
Part driver ignores the regulation of tunnel driving " no Overtaking " and " forbidding lane change ", drives into the few runway of wagon flow, this is significantly
Increase tunnel traffic security risk.At the same time, it is counted according to traffic department, after tunnel vehicle density is more than certain threshold value,
It will increase the probability of traffic accident appearance.Thus, it is necessary to enter the premise in tunnel in vehicle by certain technology or facility
The preceding wagon flow crowded state for informing the driver tunnel lane Nei Ge, allows driver to select the less lane of wagon flow, guarantees that tunnel is handed over
Logical safe and smooth operation.
Summary of the invention
The purpose of the present invention is to provide a kind of, and the multilane tunnel wagon flow based on traffic monitoring regulates and controls method, in advance
It informs and the vehicle that will drive into tunnel is guided to be transferred in the less tunnel lane of wagon flow, prevent multilane tunnel internal cause lane vehicle
Flow distribution is unbalance and increases traffic safety risk, guarantees the safe and smooth operation of tunnel traffic.
In order to solve the above technical problems, the present invention proposes a kind of multilane tunnel wagon flow regulation side based on traffic monitoring
Method, this method are executed by the multilane tunnel wagon flow regulator control system based on traffic monitoring.
Multilane tunnel wagon flow of the present invention based on traffic monitoring regulates and controls method, specifically include following steps (with

Judge traffic accident or other special statuss whether occur in tunnel between monitoring device k and monitoring device k+1；Specifically,
As ρ (k+1)zIt is significantly less than ρ kzAnd when the vehicle density increase in adjacent lane, (wherein z is positive integer and is less than or equal to number of track-lines
M), show that traffic accident or other special statuss occur in monitoring device k and the section monitoring device k+1 on tunnel inside lane z,
Control module controls the lane signal display module closure of a tunnel z, while emergency system is triggered, and department's expansion emergency is managed in tunnel
Processing and rescue operation, wherein ρ kzThan ρ (k+1)z(Tk drove to monitoring from monitoring device k for same automobile A and set the early Tk time
The time required to standby k+1)；
Particularly, if long tunnel among exist can lane change part, need the tunnel segment after lane change being regarded as another tunnel
It is renumberd, arranges wagon flow regulator control system.
Step S3: signal display module executes the instruction of control module, and it is less to drive into wagon flow by LED signal lamp guidance vehicle
Tunnel lane, LED with red fork indicates forbidden in specific implementation process, and Huang dodges expression congestion, it is careful enter；Green indicates that safety is sailed
Enter, in addition, can be as needed, it is used cooperatively by flashing light, text importing or voice broadcast equipment.
Multilane tunnel wagon flow regulator control system main composition of the present invention based on traffic monitoring include monitoring modular,
Control module, signal display module and emergency processing module section.
Monitoring modular is mainly a kind of monitoring device with image identification function, is separately mounted to the entrance in lane,
To by the Car license recognition memory in monitor area below, the calculating of the vehicle number and vehicle density that pass through is counted.
The effect of control module is to receive the data information that monitoring modular transmits, carry out by inside modules operation program
After processing, instruction is issued to signal display module and emergency processing module.
Signal display module is mainly made of LED signal lamp, including flashing light, voice alarm device, is shown by LED matrix
Control module command signal generated out, guidance vehicle drive into the less tunnel lane of wagon flow, can root in specific implementation process
According to needs, screen display equipment is shown by flashing light, voice broadcast or text and is used cooperatively.
The emergency processing module is triggered after receiving " accident " instruction that control module is sent and is sounded an alarm, and leads to
Know the expansion processing of tunnel control department and rescue operation.
