Development of Output and Outcome Models for End-results Based Winter Road Maintenance Standards
Safety Benefit Analysis and Modeling
This component investigates the quantitative relationship between road safety (maintenance outcome) and road surface conditions (RSC) measures (maintenance output).
Mobility Benefit Analysis and Modeling
This component investigates the quantitative relationship between traffic mobility (maintenance outcome) and RSC measures (maintenance output).
Performance Measures and Service Standards
The objective of this component is to evaluate alternative performance measures for monitoring winter road maintenance operations with a specific focus on their advantages and limitations as maintenance performance indicators to link maintenance input to maintenance outcomes. The research will focus mainly on the three performance categories recommended in the NCHRP Project 6-17 “Performance Measures for Snow and Ice Control Operations”, namely, bare pavement status (e.g. BP recovery time), traffic flow (e.g. speed) and crash risk (e.g. friction).
RSC Monitoring Technologies and Tools
The first objective of this component is to evaluate the performance of some existing and new RSC monitoring technologies. The second objective is to develop models and tools for RSC estimation and forecasting.
