Analysis of the Impacts of Open Residential Communities on Road Traffic Based on AHP and Fuzzy Theory

Abstract

With the continuous urbanization in China, the number of private cars has grown rapidly in urban areas, leading to increasingly prominent road congestions. Urban road networks are wide but sparse, which can easily cause congestion. To tackle with this problem, the State Council proposed the idea of "open residential community" in 2016, which is to connect the roads within the residential community with external roads to densify the road networks and increase the area of branch roads, so as to mitigate urban road traffic pressure. In order to study the impacts of open residential communities on the traffic capacity of surrounding roads, this paper first establishes an evaluation indicator system for road traffic using a number of factors such as traffic density, traffic delay time, number of intersection conflicts, road congestion rate and road accessibility based on the analytic hierarchy process (AHP) theory, and also builds a fuzzy comprehensive evaluation model. Then, with the above evaluation indicator system and model, this paper employs the VISSIM traffic simulation technology to simulate the residential community for testing. Finally, it uses the grey relational algorithm to compare and analyze the test data, and obtains the following conclusions: for residential communities with a large area and large traffic volume and those with a small area and large traffic volume, the surrounding road traffic is significantly reduced, and the traffic pressure is greatly alleviated; the effect comes second for those with a large area and small traffic volume; and for those with a small area and small traffic volume, surrounding traffic sees no improvement.

Strategies to Enhance the Teaching Competence of University Teachers in English Major

“…However, considering the dynamic features of social development, the characteristics of contemporary social requirements, and the different talent cultivation goals of modern higher education, it is still of certain necessity to further discuss the existing research results, in especial, it's of important significance to create a set of appraisal systems and models to measure the teaching competence of university teachers in English major. To this end, this paper concludes and optimizes the existing research findings, establishes a novel system for measuring the said teaching competence combining with AHP and the Shannon Information Theory [17][18][19][20], and proposes an improved model for measuring the said competence, in the hopes of offering a useful evidence for enhancing the teaching competence of university teachers in English major. In this paper, the research content is organized into 5 chapters.…”

Improved Evaluation Index Systems for Public Physical Education

“…In the evaluation index set U, each evaluation index has different effects on the evaluation result; in order to evaluation these different effects, it's necessary to assign different weight values to different evaluation indices of public PE. The AHP method has the characteristics of simple calculation, reliable results, and the calculation data are easy to obtain, therefore, this paper adopted AHP [20][21][22] to obtain the weight 160 http://www.i-jet.org values of the evaluation indices of public PE. The specific implementation process is as follows.…”

Evaluation of College English Teaching Quality Based on Grey Clustering Analysis

“…And following the continuous development of modern society, the training objectives, and requirements of modern higher education for the English professionals are constantly changing, and the existing evaluation systems and strategies for college English teaching quality also have certain limitations. To this end, based on the existing research results, this paper analyzes the current status of English teaching in colleges, and discuss an improved method for evaluating the quality of college English teaching using the gray system theory [14][15] and the entropy weight method [16][17][18][19].…”
