Three-Dimensional Analysis for Determination of Anti-Glare Screen Barrier Height

Few models are available to determine the height of anti-glare screen barrier based on two-dimensional analysis. Very limited research works have been carried out considering three-dimensional analysis. A model has been developed herein to determine the height of anti-glare screen barrier considering three-dimensional analysis. Height of anti-glare screen barrier has been determined considering plane, parabolic and spherical surfaces based on three-dimensional analysis. Height of anti-glare screen barrier has been found to be constant for plane surface, and it depends on the eye height of the driver and the height of vehicle head light only and varies for other surfaces. The model has also been modified for two-dimensional analysis and is reported herein. Height of anti-glare screen barrier obtained from two-dimensional analysis is also reported herein. There is no significant change in the height of anti-glare screen barrier in case of surface with large radius. Height of anti-glare screen barrier has been recommended as 1.85 m for Indian situation.
