Improved Visibility for Snowplowing Operations

This digest describes several means, identified in National Cooperative Highway Research Program Project 6-12, that could improve visibility for snowplowing operations. The research, completed in 1999, identified several means for improving visibility for snowplowing operations. However, limited tests were conducted in this project to fully evaluate the merits of these means or the practicality of their unlimited use by highway agencies. This digest provides a summary of the work performed in this research. The material included in this digest is extracted from the final report on this project. The final report is available for loan on request to the National Cooperative Highway Research Program, Transportation Research Board, 2101 Constitution Avenue, N.W., Washington, DC 20418.
