This final report documents findings of a study concerning the enhancement of durability and vandal resistance of transit vehicle passenger-side windows. This report includes background information on the durability of transparent window materials. Also included are results and analyses of surveys of selected domestic and foreign transit authorities, surveys of window manufacturers serving the transit industry, surveys of window manufacturers serving other industries, surveys of research organizations serving the transit industry, and surveys of transit vehicle manufacturers. The focus of these surveys was to define window issues for the transit industry, with special focus on current practices, durability and vandalism issues, and existent or emerging technologies including material solutions or preventative measures, which result in longer lasting more durable transit glazing systems. Several relatively new material solutions are discussed including sacrificial ply systems, peel-ply protective films, anti-spall films for glass, coatings and aerospace transparency technologies, and window refurbishment. Special attention is focused on the need for a cooperative integrated team approach, which includes operators, security, and maintenance personnel, with a zero tolerance approach to controlling vandalism. The findings of this effort are applicable to all transit modes. |
