| In recent years,urbanization promotes the comprehensive development of society and economy.City rail transit in China has maintained the strong growth and a high amount of construction.And rail transit stations implanted in the urban space will lead to new phenomenon and problems inevitably.The research on the traditional urban space and rail transit often focuses on the efficiency of the connection,but ignores the influence of pedestrian and vehicles on urban space.Comprehensive connection efficiency not only connects with the efficiency of the traditional connection,but also takes into account pedestrian and vehicle behavior characteristics of the urban space,to combine organically and establish relationship between behavior and urban space.At the same time,because of the complex characteristics of the rail transit stations,such as complex space,large flow,strong mobility and so on,new requirements are raised to the improvement of the comprehensive connection efficiency.Under the background of the rapid development of digital technology,digital technology tools have been involved in every aspect of urban design research.At present,the digital technology application is various in urban design field,such as CAD technology,image processing technology,GIS technology and virtual reality technology.And the development of micro simulation technology provides a new approach for the urban design research.Using behavior simulation tools to study the comprehensive connection efficiency,it will reproduct phenomenon and problems in urban space and quantify the spatial data which will be more reliable to reflect the change of urban space,internal demand of the development and operation mechanism.In this paper,the influenced urban realm around city rail transit station is the research scope,pedestrian-vehicle behavior is the research object,analysing comprehensive connection efficiency of influenced urban realm around city rail transit station,setting up the evaluation system of comprehensive connection efficiency of rail transit station,supplemented with digital simulation tools as technical support.Through literature research,questionnaire survey,digital simulation and other research methods,this paper explores the construction method of evaluation system of comprehensive connection efficiency.At the same time,based on existing research,this paper further explores the applicability and feasibility of digital simulation tools in the study of pedestrian and vehicles behavior and urban space.The validity of the simulation results is verified by comparing the simulation results with the real state of urban.In this paper,"finding the problem,putting forward the problem,solving the problem" is the basic thought,it is mainly divided into the following sections:(1)The origin of the research is the main content of the first chapter.Under the background of the current urban renewal and the rapid development of traffic,"urban disease" is becoming more and more prominent.At the same time,the application of digital technology and tools is becoming more and more mature,and it also provides a new way for the research of urban design.In this paper,the characteristics of pedestrian-vehicle behavior in the influenced urban realm around city rail transit station is the research object,and the specific methods of this paper are defined by the definition of relevant concepts and literature review and on;(2)Problem posing is the main content of the second chapter.First of all,this paper expounds the characteristics of comprehensive connection efficiency.Then,based on the domestic and foreign cases,it analyzes the characteristics of different transportation modes and the characteristics of pedestrian-vehicle behavior.Finally,combined with the characteristics of urban space,establishing the intrinsic link between the target of comprehensive connection and the category of urban space;(3)Evaluation system is the main content of the third chapter.Firstly,the paper summarizes the general principles of the evaluation system construction,and establishes the target of the comprehensive connection efficiency evaluation system.Secondly,the paper sets up the classification table of the influenced factors of comprehensive connection efficiency by the method of literature comparison.On this basis,the results of the questionnaire and the fuzzy mathematics method are used to select and determine the final index of the evaluation system.Finally,using the analytic hierarchy process(AHP)to quantify the index weight of the evaluation system,establish the scoring criteria,and complete the establishment of comprehensive connection efficiency evaluation system;(4)Simulation verification is the main content of the fourth chapter.Firstly,the development of simulation technology and tools are introduced briefly.Secondly,focusing on the simulation of pedestrian-vehicle behavior,this paper discusses the application scope and types of pedestrian-vehicle behavior simulation.Then,according to the needs of the research,the simulation model and typical simulation tools are selected,and the application characteristics of Anylogic and VISSIM simulation platform are analyzed.Then,describes the effectiveness of digital simulation of the connotation and characteristics of simulation and the validity of the principle and method,using Anylogic and VISSIM to simulate comprehensive connection behavior and typical scene,and compared with the actual state,determine the validity of simulation results;(5)Case application is the main content of the fifth chapter.Firstly,from the point of view of Chongqing Lianglukou Rail Transit Station as a case study.Then,get the basic data of the site influenced realm through field research,using simulation tools to compare simulation results with city real state,evaluate the comprehensive connection efficiency.Finally,the paper puts forward the optimal design strategy of urban space and develops the urban renewal design. |
