This is the presentation speaker Lou Neudorff of CH2MHill gave on Intelligent Transportation Systems at Drive Oregon's November event (11/7/2012).

1. ITS and
Sustainability Louis Neudorff, P.E.

2. 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”.

3. 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

4. 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

Corridor
Management

6. Active Traffic Management
§ Variable Speed Displays
§ Dynamic Lane Assignment
§ Queue Warning
§ Operated in real time
based on current
conditions

8. ATM – Hard Shoulder Running

9. 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).

10. 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)

11. Other ITS Considerations for
Sustainable Transport
§ Support of Eco-driving
§ Performance Measures
– Recent MAP 21 Legislation
§ Adaptation
§ Pricing (VMT Reduction)
§ Road Usage Charging (Financial Sustainability)
