Description
Technical field
The present invention designs a kind of evaluation model, more particularly, to mixed traffic flow on a kind of signalized intersections crossing
The method for building up of degree of order evaluation model.
Background technology
Notable moving region is the important area for causing human eye vision to be paid attention to, and the object most probable moved in the region turns into
Emphasis of concern, and the focus of Recent study, in the region various traffic flows it is obvious to mix row, collide with each other effect
Region is defined as notable moving region.
At present, in China, non-motor vehicle, pedestrian proportion shared in intersection traffic stream are relatively large, therefore, mixing
Traffic flow is the important research content for solving domestic city traffic problems.Signalized intersections are that non-motor vehicle, motor vehicle, pedestrian mix
Merge the obvious region that conflicts, i.e., notable moving region.And the crossing at signalized intersections is auxiliary pedestrian's street crossing
Basic facilities.Traffic conflict on crossing can produce considerable influence to traffic order.Mainly deposited on crossing at present
In conflicting for right-hand rotation car and pedestrian, pedestrian and pedestrian and small part pedestrian and non-motor vehicle.Mixed traffic flow and its correlation are ground
Study carefully significant for solving domestic city traffic problems.Existing some scholars are to the interference and punching between mixed traffic flow
Row of advancing by leaps and bounds is studied, but the model that the assessment for order is not unified.Condition be limited (such as cost control, can not close a road to traffic) but
In the case that intersection is there is an urgent need to improve, how to determine that the priority of construction lacks certain reference frame.
In order to evaluate the conflict between mixed traffic flow to influence caused by mixed traffic flow order, present invention introduces order
The concept of sequence degree.Degree of order, i.e. traffic flow follow the degree of traffic order, be various traffic flows defer to rational movement locus and
The measurement of rule.I.e. traffic flow follows the degree of traffic order, is that rational movement locus and rule are deferred in various traffic flows
Measurement.
The both ends occurred mainly on crossing that conflict of right-hand rotation car and pedestrian, the conflict have impact on right turning vehicle
Track and speed and the speed of pedestrian, the wherein change of right turning vehicle track are characterized with radius of turn.It is pedestrian and pedestrian, non-
Conflict between motor vehicle occurs mainly in the center section of crossing, and the conflict mainly influences the rail of pedestrian and non motorized vehicle
Mark and speed, wherein, the track of pedestrian and non motorized vehicle is characterized with its distance and the ratio of displacement.
The content of the invention
In view of the deficiencies in the prior art, it is an object of the invention to provide mix to hand on a kind of signalized intersections crossing
The method for building up of through-flow degree of order evaluation model, the model definition crossing are notable moving region, can evaluate signal
