The purpose of this study is to verify the safety issue of the tinted vehicle based on the field study as well as the issue of the capacity reduction from the tinted vehicle. Through this study, an innovative experimental method to verify the issues was developed using RTK GPS receivers, and a data collection was conducted using the developed experimental method. Using the collected data, the effects of the ahead vehicle with the windows tinted on the traffic condition such as headways and acceleration noise were analyzed to test that the ahead vehicle with windows tinted too darkly affects the increasing vehicle maneuver as following the degree of tinting. This study was conducted as a frontier study and more studies, for example, full scale analyses considering various road and vehicle conditions need to be conducted in the future.

Driving directly in front of the driver of a vehicle driving in front of the vehicle and it is commonly known is affected. Responding to the car in front of the driver and the vehicle in front, and these follow the model is known as Three-Car-Following Model. Platoon vehicles to follow behind the driver's visibility is affected by the a tinted vehicle, and Parameters of the model is estimated to be affected also. In this study, in Three-Car-Followng Model parameters were estimated. and the parameter values differ about whether and how analysis was performed by the level of Visible Light Transmission Percentage. RTK GPS receiving data through field experiment analyzed based on sensitivity of three car by Visible Light Transmission Percentage and ${\gamma}$. And With statistical verification of driving directly in front of the driver in front of the vehicle and that the moving vehicle is influenced also confirmed. Also Visible Light Transmission Percentage is lowered, the vehicle in front of the driver's behavior showed sensitive reactions. In the further need to research for influence analysis of traffic flow capacity by the level of VLT.

최근 사용되는 스마트 홈 시스템은 다양한 환경의 효율성, 편안함, 기능성을 추구한다. 하지만 기존 스마트 홈 시스템에는 실내 채광 조절이 블라인드나 커튼과 같이 사람의 관리가 필요로 한 부분이 적용된다. 본 논문은 이를 보완하고자 현재 자동차 및 항공기에 사용되는 스마트 윈도우처럼 주변 조명 조건에 따라 투명도를 조절할 수 있는 스마트 글라스나 필름 사용을 제안한다. 기존 별도의 관리가 필요한 블라인드, 커튼 등과 달리 창문 자체적으로 외부 채광을 조절하고 실내 조명과 연동하여 자동적으로 실내의 환경을 변화시킨다면 사용자의 경제성과 편의성을 증가시키는 효과를 얻을 것이다.
