The Research On Luminous Environment Assessment Of Urban Subway Station

Recent years,with the continuous development of China’s economy to the pressureon urban traffic is constantly increasing,which makes the subway more and more widelyin people’s daily life.The city subway booming to play a significant role in the pubicservice and social management.Hower,in a fast and secure to meet the transportationneeds at the same time,the design and improvement of the artificial environment of thesubway station also can not be ignored.Since most of the subway station undergroundparticularity,the luminous environment has become an important part to improve theartificial environment of the subway station.However,due to the lack pf scientificevaluation system and tools for evaluation,subway station lighting design sector isdifficult to grasp the design results eventually meet the design requirements and theneeds of people.Therefore,the research on the evaluation of the city subway station lightenvironment is particularly urgent.This paper is combined the study which is the National Natural Science Foundationproject”the research of the space of flows artificial luminous environment optimizationand energy-saving control”, researchd the city subway station luminous environmentevaluation index and evaluation method, established the city subway station luminousenvironment evaluation index system, provided a theoretical basis for the improvementof city subway station lingting design. The following several respects of research iscompleted.(1)According to the city subway station luminous environment, this paper isanalysed the impact factors of luminous environment comprehensively on the basis ofthe theoretical results and practical experience of luminous environment evaluationwhich in buildings at home and abroad. (2) Combined with a series of national construction and railway lighting designspecifications, complexed taeget analysis and Delphi method, builded a evaluationindex system of luminous environment in city subway station which include four levelindicators of visual environment color environment psychological environment and thespace environment, gave the weight value to each indicator using AHP andquestionnaire.(3) Used fuzzy comprehensive evaluation method and comprenhensive evaluationmethod of grey clustering to build city station luminous environment fuzzycomprehensive evaluation model and grey clustering comprehensive evaluation model,applied this two models to the instance of luminous environment assessment in Xi’anmetro line station, analyzed and detected the effectiveness of the evaluation results,proposed a number of recommendations to improve the luminous environment ofXi’an metro line station.
