Description
Technical field
The present invention relates to the rational evaluation method in lane in one, a kind of especially intersection dislocation lane is rational fixed
Measure evaluation method.
Background technique
The setting in the lane of intersection dislocation at present has the following problems:
1, dislocation lane design in intersection is unreasonable, leads to the vehicle for facing left turn lane or side point band or non-motorized lane
The vehicle driving trace in road has some setbacks, and reduces the time-space distribution utilization efficiency of intersection；
2, dislocation lane design in intersection is unreasonable, and angle is larger when vehicle being caused to drive into exit lane, increases traffic punching
It is prominent, it is easy to collide side point band or non-motorized lane, safety is lower.
Summary of the invention
To solve the above problems, the present invention provides a kind of road conditions according to intersection, evaluation index value is calculated, from
And quantitative assessment dislocation lane setting whether reasonability, and then can to avoid in operational process because dislocation generate traffic ask
Topic provides a kind of intersection dislocation lane conjunction of foundation for the design and optimization decision in Intersection at Grade of Urban Road dislocation lane
The quantitative evaluation method of rationality, the specific technical proposal is:
A kind of intersection dislocation rational quantitative evaluation method in lane, comprising the following steps:
According to the road conditions of intersection, the lateral shift distance Wi and dislocation lane stop line in each dislocation lane are obtained
With longitudinal transition distance Li of exit ramp side point band or the stop line in opposite lane；
According to evaluation index deviation ratio computation model, the deviation ratio value in intersection dislocation lane is calculated；
R=Wi/Li
In formula:
R- deviation ratio；
According to deviation ratio value, the reasonability of quantitative assessment intersection dislocation lane setting.
Preferably, the deviation ratio of the quantitative assessment are as follows:
In formula,
V- automobile driving speed, V≤42km/h；
WiThe change width value in maximum dislocation import lane and outer outlets lane, m.
Compared with prior art the invention has the following advantages:
A kind of rational quantitative evaluation method energy quantitative assessment intersection in intersection dislocation lane provided by the invention is wrong
The reasonability of position lane setting eliminates unreasonable dislocation lane setting bring hidden trouble of traffic, the low and friendship including efficiency
Logical conflict；It can be determined the need for according to evaluation index deviation ratio value into one when carrying out reasonability quantitative assessment to dislocation lane
Step optimization space layout.
Detailed description of the invention
Fig. 1 is the schematic diagram of lateral shift distance and longitudinal transition distance of the invention.
Specific embodiment
Now in conjunction with attached drawing, the invention will be further described.
The rational quantitative evaluation method in lane as shown in Figure 1, a kind of intersection misplaces, comprising the following steps:
According to the road conditions of intersection, the lateral shift distance Wi and dislocation lane stop line in each dislocation lane are obtained
With longitudinal transition distance Li of exit ramp side point band or the stop line in opposite lane；
According to evaluation index deviation ratio computation model, the deviation ratio value in intersection dislocation lane is calculated；
R=Wi/Li
In formula:
R- deviation ratio；
According to deviation ratio value, the reasonability of quantitative assessment intersection dislocation lane setting.
Wherein, the deviation ratio of the quantitative assessment are as follows:
In formula,
V- automobile driving speed, V≤42km/h；
WiThe change width value in maximum dislocation import lane and outer outlets lane, m.
According to the road track recommended in national standard " GB5768.3-2009 road signs and graticule specification " on section
Transition minimum value calculation formula,
Wherein, urban road management speed≤60km/h, the intersection Through Lane speed of service by section 0.7 consider, because
This straight trip speed≤42km/h, i.e.,Deviation ratio R is derived according to the above parameter, therefore is actually answered
It is reasonable with being control R no more than 0.1.
A kind of rational quantitative evaluation method energy quantitative assessment intersection in intersection dislocation lane provided by the invention is wrong
The reasonability of position lane setting eliminates unreasonable dislocation lane setting bring hidden trouble of traffic, the low and friendship including efficiency
Logical conflict；It can be determined the need for according to evaluation index deviation ratio value into one when carrying out reasonability quantitative assessment to dislocation lane
Step optimization space layout.
