Research On Comfort Of Lighting Environment Of Metro Train

In recent years,with the rapid development of urban rail transit,metro trains have expanded people’s employment radius and promoted urban economic development,but longdistance commuting will have an impact on passengers’ comfort.The existing research on ride comfort mainly focuses on vibration,noise,pressure and other factors.Due to the particularity of metro train operation,compared with high-speed train,the influence of vibration and noise on the comfort is small,but lighting is an important factor affecting the comfort of metro train.The quality of the lighting environment will affect the eye health and ride comfort of passengers.The existing research on comfort of trains mainly focuses on vibration,noise,pressure and other factors.,but the research on lighting environment comfort is relatively scarce,and there are no lighting environment evaluation indicators and evaluation models dedicated to metro trains.At the same time,these indicators are often based on the existing objective physical quantities,not from the individual passengers,combined with the subjective psychological feedback and needs of the passengers to design the light environment of the metro train.Therefore,carrying out research on the comfort of metro train lighting environment,enriching the research of metro train lighting environment indicators and evaluation models,has the important practical significance for improving the lighting environment of metro trains and increasing the ride comfort of passengers.Supported by the national key research and development program "Environment Friendly Technology for Rail Transit Train"(2017YFB1201103),this thesis mainly carries out the following research work:Based on the related theories of visual characteristics,this thesis explores the impact of metro train lighting environment on passengers’ ride comfort from both physiological and psychological perspectives.According to the spatial characteristics of metro trains,the influencing factors of metro train lighting environment and related evaluation indicators and calculations are analyzed and sorted out.Aiming at the current deficiencies in the evaluation indicators of the lighting environment in metro trains,this thesis takes the lighting environment of metro trains as the research object.Through the field measurement and questionnaire survey of the lighting comfort of Guangzhou Metro Line 6,according to the investigation results of different metro passenger behavior states,a set of illuminance comfort evaluation device based on passenger behavior is designed,a series of lighting comfort tests were carried out on the test platform and indicators for the lighting comfort of passengers in different behavior states were proposed,and the illuminance comfort evaluation model of passengers in different behavior states was established.Finally,according to the test results,the lighting environment of the metro train is optimized,the optimization plan is designed and proposed according to the actual operation of the metro train,and it is simulated based on DIALux,also the feasibility analysis and verification of the optimization plan are carried out through the test platform.
