Transforming Transportation: The Role of Intelligent
Transportation Systems
Matthew J. Schiemer, PEAugust 18, 2011
Why ITS?
• To save “lives, time and money” in the transportation field, we must look beyond the traditional infrastructure construction and maintenance model we’ve followed for 80+ years.
• Focus on the operation of roadways and transit systems.Think about airport operation.
• ITS is one of the most important tools in the operations toolbox.
• ITS involves the application of advanced technologies to transportation.
• Compared with traditional infrastructure, the cost of ITS is low and the B/C ratio is high.
• Remember: the focus should be on Operations.

“We Can’t Build Our Way Out of Congestion”
Typical ITS Benefits and B/C Ratios
• Fewer accidents• Fewer secondary
accidents• Decreased accident
severity• Fewer injuries and less
severe injuries• Reduction in fatalities• Less delay and stops• Reduced travel times• Less travel time
variability• Increased traveler
satisfaction
• Travel demand management
• Reduced fuel consumption• Reduced emissions• Increased system capacity• Support economic
development• Lower O&M costs
• Fewer accidents• Less infrastructure
damage• Fewer overweight
vehicles• Reduced transit costs
Typical B/C Ratios of 10:1 to 40:1
ITS Benefits and Costs Resources
• US DOT – ITS Joint Program Office – Knowledge Resources– Benefits, costs, lessons learned, etc.

• International Benefits, Evaluation and Costs (IBEC) Working Group – Representatives from 40 countries

Operations Performance Measures
“You Can’t Manage What You Don’t Measure”
• We can not expect to meet our goals and successfully manage (operate) the transportation network if we are not measuring performance.
• Well-designed performance measures help us to determine if our actions are helping us meet our goals, achieve expected benefits and to:– Set policy– Allocate resources– Choose between options– Report on results– Reveal problems and areas for improvement
Operations Performance Measures
• Incident Duration– Incident detection time– Incident response time– Incident clearance time– Incident recovery time
• Travel Times and Delay
• Travel Time Reliability (Variability)
• Toll Plaza Delay
• Accident and Fatality Rates (primary and secondary accidents)
Operations Performance Measures
• Provision of Traveler Information– ITS Field Device Coverage, Availability and Information
Quality– Phone and Web (511) Coverage, Availability and Info
Quality
• User Satisfaction (Surveys)– Traveler Information Quality and Relevance (DMS, HAR,
511)– Device Type Preference and Usage (DMS –vs- HAR)– Overall Satisfaction with Range of Services (FSP, EZ-Pass,
etc).
• ITS System Performance– Availability (up-time) of ITS Field Devices and Systems– Accuracy of data and properly calibrated devices and
systems– Mean Time Between Failures (MTBF) and Mean Time to
Repair
Operations Performance Measures Resources
• US DOT – Office of Operations – Operations Performance Measurement Program– Extensive information and external links

Keys to Success of an ITS Project or Program
• Technical• Political• Institutional • Legal• Financial• Public and private
sector solutions/PPP
