Problems solved by technology

[0005] (1) In the past, the research on the lane edge of large-scale hubs mainly focused on the dynamic analysis of the various traffic facilities in the hub, and less consideration was given to the length setting of the lane edge
[0006] (2) In the process of researching the problem of setting the length of the lane edge, the lane setting form of the lane edge was not considered, and the lane edge forms were generally classified into one category for research and analysis, lacking exact theoretical methods and data support
Research on the application of cellular automata based on an integrated simulation environment is still in its infancy

Embodiment Construction

[0059] 1.1 Analysis of traffic flow characteristics of lane-side design with intermediate fast lanes

[0060] Under the lane-side design form with fast lanes, the fast lanes divide the parking spaces along the lanes, leaving special areas for vehicles to enter or leave the lanes, reducing the interweaving conflicts between vehicles, but it is fast The setting of the passage also reduces the utilization rate of the lane side, so its setting form and scale need to be analyzed in conjunction with the specific traffic conditions of the terminal, such as figure 1 Shown.

[0061] Note: m+1, m+2, m, m-1 are vehicles on the expressway;

[0062] n+3, n+1, n-2, n-4 are vehicles that are parking and dropping off in the inner parking lane;

[0063] n+2, n-1, n-3 are vehicles that are parking and dropping off passengers in the outer parking lane;

[0064] n+4 means that the outer parking lane is leaving and preparing to weave vehicles;

[0065] n is the intertwined vehicle for the inner parking lan...

Abstract

The invention belongs to the technical field of road designing, and provides a definite method for determining the side length of a large transport junction road with middle fast lanes. In order to achieve the purposes, the method adopts the technical scheme that the method for determining the side length of the road with the middle fast lanes adopts two-dimensional cellular automata model analog simulation as a platform to perform integration and simulation to an objective and obtains lane place and quantity optimization data through the steps including analysis of the traffic flow characteristics of the side design form of the road with the middle fast lanes, and details of multiple effects of the parking model objective function, visual perception and lane changing behavior. The method is mainly applied to the road designing.

Description

Technical field [0001] The invention belongs to the technical field of road design, and particularly relates to a method for determining the side length of a lane with an intermediate fast lane. Background technique [0002] The construction of a comprehensive and integrated passenger transportation hub has become the development trend of the city's comprehensive passenger transportation system. The lane side is a unique transportation facility in the hub, and it is a centralized set of vehicles to pick up and drop off passengers to realize the conversion of the flow of people and vehicles in and out of the station. area. As a key place for the connection of people and vehicles, it is one of the most likely to form bottlenecks, which affects the use of large-scale transportation hub design functions. [0003] Through the study of relevant documents at home and abroad, it can be known that abroad, as early as the 1960s, the planning and layout of lane-side facilities of large-scale...
