Abstract:The Federal Highway Administration Road Weather Management Program started development of Integrated Modeling for Road Condition Prediction (IMRCP) in 2015 to provide data and decision support for transportation system management and operations in weather events. IMRCP gathers traffic and weather data and forecasts. It creates new forecast data for road weather and traffic conditions from the collected data. It provides tools for what-if analyses and views of the data from past, present, and future operational time horizons. It supports transportation system and emergency operations in decision-making and after-action reviews. Previous phases of IMRCP had developed the foundational traffic and weather data system components. IMRCP phase 4 has improved and deployed the system in Ohio and Louisiana, expanding system capabilities and applicability to extreme events while addressing functional gaps identified in earlier phases. The Ohio deployment focused on IMRCP as a tool for planning, monitoring, and post-event assessment of traffic management and operations during adverse, primarily winter-weather events. The Louisiana deployment investigated IMRCP use cases in tropical-storm-event preparation, response, and recovery. IMRCP enhancements and applications developed in phase 4 have been documented to support future deployments. The final report describes the phase 4 development, demonstration, evaluation, and assessment of IMRCP. It provides a summary description of the system design, study area of deployment and engagement, operations experience, evaluation, and recommendations for further study.
