Abstract:This report documents the Buffalo-Niagara Integrated Corridor Management (BNICM) deployment planning study for portions of the region’s freeway network. Integrated Corridor Management (ICM) provides technology-enabled transportation management and operations strategies that seek to optimize the use of existing infrastructure. Following a presentation of the overall concept of operations for the BNICM deployment, the report presents a detailed analysis of the impacts of two ICM alternatives, one freeway-focused only, and one also including arterial traffic signal optimization, with cost-benefit analysis determining that the latter is optimal. Travel-time savings was found to be the single largest category of benefits from the BNICM deployment, with benefits greater during day-to-day morning and afternoon rush hour periods than during less-usual scenarios (crashes, professional sports events, etc.). Of the ICM strategies considered, the highest-impact strategy was found to be Dynamic Traveler Information, Freeway Incident Detection and Service Patrol. This report concludes with a plan of next steps for implementing the BNICM’s strategies and monitoring, once operational.
