About the research

Abstract: The objective of this research was to conduct an independent evaluation of winter maintenance performance indicator and LEM data collection and processing practices. The evaluation sought to establish whether the correct data were being collected and if the appropriate analyses were being conducted on the available data. Appropriate analyses means analyses that are able to identify successes and isolate best practices. Once we can distinguish and measure success, management can reward and encourage it elsewhere.
