Embodiment Construction

[0038] The present invention will be further described in detail below in combination with specific embodiments.

[0039] Deciding whether to set up a multi-purpose lane and how to design a multi-purpose lane has an important impact on the service level and traffic capacity of the expressway. The present invention analyzes and researches the design method of the multi-functional lane of the main road of the expressway by using the delay and capacity analysis method from the microcosmic point of view.

[0040] The present invention is based on delay and traffic capacity multifunctional lane design method of expressway main road, comprises following steps, as figure 1 Shown:

[0041] Step 1. For forecasting the demand of multi-purpose lanes on the main road of expressways, it is necessary to start with their functions and compare the traffic benefits of the main road with and without multi-purpose lanes, that is, the vehicle delay and capacity of the main road. First of all, it ...

Abstract

The invention discloses a method for designing a main road multifunctional lane of an express way based on delay and traffic capacity, comprising the following steps of: determining functions of the main road multifunctional lane of the express way; investigating and counting the traffic to obtain road traffic condition and driver behavior parameters of the express way; selecting a simulation software and calibrating a model; creating a traffic simulation model; for each function of the multifunctional lane, adjusting conditions, such as main road traffic flow, composition and the like of theexpress way, obtaining main road vehicle delay and traffic capacity of the express way under different situations, and analyzing the obtained information to get the conclusion of setting analysis on the multifunctional lane based on different functions; synthesizing the conclusion of the setting analysis under each function to get the conclusion of design analysis on the multifunctional lane, andperforming traffic design of the multifunctional lane based on the final conclusion. The method provided by the invention fills a gap in design analysis and method of the multifunctional lane, and can provide basis for scientific and rational design of the main road multifunctional lane of the express way.

Description

technical field [0001] The invention relates to a traffic engineering design system, in particular to a design method for a multifunctional lane of an expressway main road based on delay and capacity. Background technique [0002] Expressway is one of the main engineering measures to alleviate traffic congestion in big cities. At present, cities in China that have established relatively complete expressway systems mainly include Beijing, Shanghai, Guangzhou, Tianjin, and Shenzhen. Although some achievements have been made in the construction and research of expressway in our country, there are still many problems to be solved further. [0003] In the expressways that have been built in China, vehicles on the main road usually make emergency stops at the emergency parking belt or the outermost lane of the main road. Vehicles entering and exiting the main road usually adopt the method of accelerating or decelerating in the outer lane of the main road. When the vehicle is actu...
