The focus of this project was to explore the possibility of ICM in Suffolk County, NY. ICM is considered one of the key strategies of Transportation Systems Management and Operation (TSMO), which involves multimodal and multi jurisdictional efforts in managing congestion caused by incidents along major commute corridors. As part of this research effort, a data driven approach was adopted using available data sources to analyze, quantify, and identify incidents and their traffic impacts. The study area encompassed eight major roadways throughout the county. The trip pattern information from the New York Metropolitan Transportation Council Best Practice Model was supplemented by StreetLight Traffic Data to ensure the use of up-to-date traffic data in order to have an accurate understanding of traffic patterns. In addition, the extensive data available in TRANSCOM Data Fusion Engine (DFE) was used to identify incident scenarios and their travel time impacts, to be analyzed in the simulation model to assess benefits of ICM response plans. To evaluate the potential impacts of ICM response plans, different micro simulation scenarios (in TransModeler) were developed. They evaluated the benefits of ICM response plans that have been triggered to handle incidents along I-495 (Long Island Expressway). The scenarios analyzed incidents at different locations (Eastbound versus Westbound) as well as different time durations. The analysis results indicated potential travel time savings of 30-40% on average.
