ICM systems offer the potential to manage both travel demand and network demand in normal and abnormal conditions. Through increased awareness, decision-support, and institutional coordination, ICM systems strive to change the traditional reactive model of traffic management to a proactive approach. With ICM, system operators take action before corridor performance degrades and, in cases where degradation has already occurred, take action to promptly restore normal conditions.
Traditionally, ICM is typically applied in an urban setting where multiple transportation modes are readily available. NCDOT is planning to apply ICM principles, but in more rural applications where less modal and network options are likely to exist. These initiatives will provide potential opportunities to measure benefits and provide guidance for future implementation of ICM elsewhere in the state.
This research effort will encompass a before and after analysis of the NCDOT ICM pilot application, sketch-planning models for estimating the impacts in North Carolina, and a guidance document and outreach material to enable NCDOT, municipal agencies and emergency services to effectively implement ICM principles.
