Sustainability has three parts:§ Environmental Protection (Green)§ Economic Sustainability (Mobility and Reliability)§ Social (Safety and Human Values)“Mee$ng, and some$mes re-‐deﬁning, the mobility needs of the present without compromising the ability of future genera$ons to meet their needs”. o ITS America Policy Statement on Sustainable Transporta$on
Transportation Systems Management & Operations§ Integrated Corridor § Coordinated Traffic Signal Timing/ Management (ICM) Adaptive Control§ Active Traffic Management § Transit Enhancements (Bus Rapid (ATM) / Managed Motorways Transit and signal priority)§ Managed Lanes (HOV, HOT) § Incident & Emergency§ Regional Coordination Management§ Multi- Modal Traveler § Ramp Management Information § Road Weather Management Existing & Emerging Strategies Supported by ITS Technologies• Manage Congestion / Increase Reliability – Economic Sustainability• Enhance Safety / Reduce Crashes – Social Sustainability• Reduce Stops & VHT (Emissions) – Environmental Sustainability
Integrated Corridor Management§ ICM - “Operational coordination of multiple transportation networks and cross-network connections comprising a corridor, and the coordination of institutions responsible for corridor mobility”§ Integration City 1 – Traffic Signal System – Operational P – Technical Regional Rail Agency – Train Management System – Institutional§ Pro-active State DOT – Freeway Management System Bus Company – AVL system City 2 – Traffic Signal System 4
Managed Lanes – HOT / Express Toll§ High‐occupancy/Toll (HOT) lanes – Non-HOV vehicles can use HOV lanes by paying toll • Toll is varied based on average speed • No less than 45 mph 90% of the time§ Express toll lanes – All vehicles are charged toll (variable)to use the lane(s).
Connected Vehicle• Vehicle to Vehicle (V2V) Communications for Safety• Vehicle to Infrastructure (V2I) Communications• Real-Time Data Capture and Management• Applications for the Environment: Real-Time Information Synthesis (AERIS) 10
