Abstract
Existing friendship, which is installed, in operation road applies guardrail detection method, it can be conducive to traffic control department to guardrail safety true, accurate evaluation and control are carried out on the basis of objective monitoring data, it is also beneficial to owner and management and onsite acceptance is carried out to guardrail according to specification index request, it is characterized in that, the following steps are included: selecting the default position of collision of detected guardrail on the operation road with guardrail, the default position of collision is collided according to default collision angle and default impact velocity using the detection vehicle with automated driving system, and security performance evaluation is carried out to the detected guardrail according to collision result data and specification index request.
Description
Technical field
The present invention relates to existing friendships in highway communication operation road to install the detection technique applied, especially a kind of operation road
In existing friendship install and apply guardrail detection method, by detecting the combination of vehicle and automated driving system, to both under true road conditions
There is guardrail to carry out live drive test, traffic control department can be conducive to guardrail safety on the basis of true, objective monitoring data
Accurate evaluation and control are carried out, owner and management is also beneficial to according to specification index request and onsite acceptance is carried out to guardrail.
Background technique
The development of highway communication be unable to do without the synchronized development of traffic safety facilities, and traffic accident directly endangers the people's
The security of the lives and property, this allows for people and increasingly payes attention to highway safety, this also promotes the continuous of highway safety evaluation standard
It improves.For example, regulation, " highway barrier security performance in " highway barrier security performance evaluation standard " (JTG B05-01-2013)
It should be evaluated using field vehicle full scale crash test ".Inventors believe that " field vehicle full scale crash test " therein is not only one
Accurate basic demand is evaluated in a realization, and is one and is ensured that impact test is true, objective conditional guidance.For guardrail
Speech, just really works when protective performance is only actually occurred to traffic accident, just will receive actual inspection, and thing occurs
Therefore road conditions and road on guardrail situation and previous experiments place be arranged the case where it is always different, therefore, run road in both
Having friendship to install the disadvantage for applying guardrail has the process gradually shown.In fact, by the traffic accident to happen occasionally, existing shield
The security performance on column inevitably causes to query.But existing friendship in operation road is installed and applies whether guardrail meets new specification
Index request, it is difficult that there is evaluations, detects because even changeing to test site, it is also difficult to reach accurate, true, objective
Evaluation criterion.Inventors have contemplated that if by detect vehicle combined with automated driving system, it will be able to abandon test site by
The disadvantage of limit carries out live drive test to existing guardrail under true road conditions.In view of this, the present inventor completes the present invention.
Summary of the invention
The present invention is in view of the deficiencies in the prior art or insufficient, provide in a kind of operation road it is existing hand over to install apply shield
Column detection method carries out live road to existing guardrail under true road conditions by detecting the combination of vehicle and automated driving system
It surveys, traffic control department can be conducive to, accurate evaluation and handle are carried out on the basis of true, objective monitoring data to guardrail safety
Control is also beneficial to owner and management according to specification index request and carries out onsite acceptance to guardrail.
Technical scheme is as follows:
Existing friendship, which is installed, in operation road applies guardrail detection method, which comprises the following steps: is having guardrail
Operation road on select the default position of collision of detected guardrail, using the detection vehicle with automated driving system according to pre-
If collision angle and default impact velocity collide the default position of collision, and are referred to according to collision result data and specification
Mark requires to carry out security performance evaluation to the detected guardrail.
Velocity sensor is installed on the detection vehicle.
The detection vehicle uses robot driver, and the robot is sitting on operating seat.
The detection vehicle uses the form of minibus or motor bus or monoblock type lorry or the formula lorry that tows the head.
The guardrail is corrugated beam barrier or concrete guardrail or combined type guard bar or Cable Barrier or new material guardrail.
Testing result data acquisition device is configured on the detection vehicle.
Technical effect of the invention is as follows: existing friendship, which is installed, in present invention operation road applies guardrail detection method, with
The road of operation is detection scene, is installed using the friendship being already installed on road and applies guardrail as detected object, by detecting vehicle
The limited disadvantage in test site, the risk that driver can either be avoided to operate, and energy are abandoned in combination with automated driving system
Enough accurate setting position of collision, collision angle, impact velocity are to improve detection accuracy, detection efficiency and detection validity or authority
Property, accurate evaluation and handle are carried out on the basis of true, objective monitoring data to guardrail safety to be conducive to traffic control department
Control is also beneficial to owner and management according to specification index request and carries out onsite acceptance to guardrail, sufficiently ensures and reinforces highway shield
The security performance on column.
The features of the present invention is as follows: (1) friendship in operation, which is installed, applies protective fence and detects (drive test) on the spot, detects the peace of guardrail
Full performance.(2) unmanned to combine with real road, speed, angular accuracy are high.(3) vehicle can be any existing shape
Formula, minibus, motor bus, monoblock type lorry, the formula that tows the head lorry meet examination criteria.(4) guardrail includes corrugated beam barrier, mixes
Solidifying soil guardrail, combined type guard bar, Cable Barrier, new material guardrail.
Detailed description of the invention
Fig. 1 is that existing friendship installs and applies guardrail detected status schematic diagram in the operation road for implement the method for the present invention.
Fig. 2 is the detection vehicle structure schematic diagram for the method for the present invention.
Fig. 3 is the schematic diagram for runing vehicle collision guardrail in road.
Appended drawing reference lists as follows: 1- runs road；2- guardrail (or to be detected guardrail)；3- detects vehicle；4- is pre-
