Highlights-Capacity
• Travel Demand Model Partnerships (C10):
States/MPOs can partner with bidders
• Workshops on Key Decision Points (C01): need
folks from “the trenches”
• Web-based Performance Measures (C02):
project finishes in a month
• Case studies on economic impacts of highway
expansion (C03): suggestions needed for cases
• Contributions of operations, technology, design
(C05): need data sources on arterial flow

Urban, rural, suburban
Weather, topography, design factors
Other data sources
Qualified contractors
• Rodeo to test roadside/roadway data
collection capabilities (S03/S04)
SHRP 2 Reliability Research
reduce congestion through
incident reduction, management,
response, and mitigation
$18 million
12 projects
Reliability
Performance Measures
• Travel Time Variability
• Travel time index: Average travel time/free-flow travel time
• Planning time index: 95th percentile travel time index
• Buffer time: time added to trip to arrive within a window with
acceptable probability
• Buffer index: (mean – 95 percentile)/mean
Traffic Math 101
75 vs. 90 Minutes Clearance Time:
Explaining the Value of 15 Minutes Saved
• Example:
–
–
–
–
–
–
I-5 northbound, Fife vicinity
Average 8% trucks
Two (of four) lanes blocked
6:00 a.m., typical Wednesday
$14 - $18/hour Auto Delay Cost
$56/hour Truck Delay Cost
• Cost savings of clearing
15 minutes faster =
$146,000
