Abstract
TRB’s Transportation Research Record: Journal of the Transportation Research Board, No. 1911 assesses topics in maintenance management, work zone traffic control, signing and marking materials, and winter maintenance. Specific subjects include a life-cycle comparison of signpost materials and types, an evaluation of late merge traffic control in work zones, the effectiveness of automated work zone information systems, the wet night visibility of pavement markings, and the development of a storm severity index. The papers contained in this volume were among those presented at the 84th Annual Meeting of the Transportation Research Board in January 2005.
