Methods For Spatial Design Of Urban Street At Intersections Based On Functional Requirements

Supported by the project of Chongqing science and technology: Methods for spatial design of urban street at intersections based onfunctional requirements, through to Chongqing intersection geometric condition, traffic flow, traffic accident, ancillary facilities and road intersection traffic control situation material collection and reorganization has conducted the thorough research to the urban road plane road intersection's design method, And has carried on the discussion to the plane road intersection quality synthetic evaluation method. The primary coverage is: Through the intersection of Chongqing operation research, analysis of the plane caused by intersections and traffic congestion a major factor in the accident, as well as the design elements of the intersection of intersection capacity and the impact of safety; the use of video technology and artificial observation techniques to study the intersection of space within the scope of motor vehicle and pedestrian traffic behavior, behavior analysis of traffic capacity of intersections and traffic safety impact; through the Analytical Hierarchy Process (AHP) to establish a comprehensive evaluation index system intersections, and these effects comprehensive quantitative indicators, access to integrated services capabilities intersection quantitative indicators; match from the traffic capacity, access efficiency, safety, environmental harmony, and arrangement of ancillary facilities such as study space for intersection design; Finally, put forward constructive plane junction of several typical design example.
