Plane intersection left turn waiting area setting evaluation method

Abstract

The preset invention discloses a plane intersection left turn waiting area setting evaluation method, and relates to the field of traffic organization design of urban road intersections. The method comprising following steps: Step 1, through investigating a left-turn traffic flow, evaluating whether setting a left-turn waiting area is required; Step 2: through calculating length of the left-turn waiting area, deterining whether the left-turn waiting area can be set; Step 3: through drawing a left-turning vehicle driving track, determining whether the left turn waiting area can be set; step 4,through a signal control setting mode, determining whether the left turn waiting area can be set. Compared with past where senior transportation engineers are required to determine through experience,the method confirms implementation effect through a large number of data surveys, the evaluation method is more scientific and reasonable, reduces manpower and material resources.

Description

technical field [0001] The invention relates to the field of urban road intersection traffic organization design, in particular to a setting evaluation method for a left-turn waiting area at a level intersection. Background technique [0002] Urban signalized intersections are the main locations where traffic flow conflicts occur, and their capacity restricts the capacity of the entire road network. The traffic and management of left-turning vehicles is the key and difficult point of restricting the capacity of signalized intersections. In order to solve the impact of left-turn traffic flow on the intersection, improve the efficiency of left-turn vehicles, and make full use of the space resources of the intersection, the setting of left-turn waiting area is the best method to solve the impact of left-turn traffic flow on the intersection. However, in setting up left-turn waiting areas at intersections, there is no scientific and effective method for evaluating whether left-t...

Problems solved by technology

However, in setting up left-turn waiting areas at intersections, there is no scientific and effective method for evaluating whether left-turn waiting areas can be set. It often requires senior traffic engineers to rely on experience to judge and verify the implementation effect through a large number of data investigations. Evaluation methods Unscientific and consumes huge manpower and material resources
