A Brief History of SHRP 2
• Role of special-purpose research programs:
focused, large-scale program of limited
duration
• Success of first SHRP: Superpave, winter
maintenance
• SHRP 2 proposed 2001; NCHRP with
matching funds from FHWA develop detailed
research plans
• SAFETEA-LU authorized the program
• $218 million, 9 years, ends 3/31/15
SHRP 2 Origin & Philosophy
• Needs identified by State DOT and industry
leaders—driven by customer-oriented goals:
– Make highways safer: revolutionary change
– Fix highways: address epidemic of aging
infrastructure
– Reduce congestion: increase physical and
operational capacity
• Success requires non-traditional approach:
– Multiple disciplines
– Collaboration with non-DOT stakeholders
– Portfolio: from new knowledge to practical tools to
allow existing innovations to be more widely used
Four Focus Areas
• Safety: fielding the largest-ever naturalistic
driving study to reduce crashes and save lives
through understanding driver behavior
• Renewal: making rapid, innovative
construction possible for “ordinary” projects
• Reliability: Providing management and
technical tools to reduce congestion through
operations
• Capacity: Systematizing collaborative decision
making to achieve better, faster project
decisions
Program Governance
• 50+ committees; 500+ members
• Oversight Committee
– Chair: Kirk Steudle, Michigan DOT
– Majority of members from state DOTs
• 4 Technical Coordinating Committees:
–
–
–
–
–
–
46% current and recent state DOT employees
11% other transportation agencies
17% consultants, contractors, suppliers, auto mfrs, etc.
10% federal, police, fire, other non-transportation
16% researchers
Plus FHWA, AASHTO, and other liaisons
• ETGs/TETGs
– Transportation and non-transportation expertise
Status of Research Program:
The Numbers
• 106 contracts to date, 37 complete, 10-12 new
contracts by end of 2012
• Nearly all of the $218 million is committed
• More than 500 expert committee members
• More than 300 research contractors
• 49 reports published or in production/review
• 30+ web tools, databases, software apps
• 24+ pilots conducted with state DOTs
Safety: Strategic Rationale
• Driver behavior is key:
– Primary factor in two-thirds of crashes
– Contributing factor in more than 90% of crashes
– Hardest to study; the thing we know the least about
• Opportunity: Naturalistic Driving Study (NDS):
– Miniaturized sensor technologies & increased
computing capacity: can observe real-world driving
– Method proven with 100 car study at VA Tech
– Crash, pre-crash, near-crash, and “normal” driving data
• SHRP 2 scales up NDS for more robust results
– 3000 drivers, 6 sites, all ages
– Data to be available for other researchers for decades

Safety Highlights
• Progress on data collection:
–
–
–
–
2,122 participants so far
384,000 trips; 5 veh-yrs of data per day
3,100 center-line miles of roadway data
Approval to collect cell phone records and
“supplemental” data
• First four analysis projects begun
• Interest in using data from outside of SHRP
2 (FHWA, NHTSA, auto mfrs, academics,
IIHS, AAA FTS, etc.)
Initial Analysis Projects
• Rural 2-lane curves – Iowa State University
– Ex. App : more cost-effective roadway measures to
prevent crashes
• Offset left-turn bays – MRI Global
– Ex. App: cost-effective intersection design
• Driver inattention – SAFER, Chalmers Univ.
– Ex. App: vehicle technology to track driver attention,
warn distracted drivers
• Crashes on congested freeways – U. of MN
– Ex. App: effective methods to warn drivers of
downstream congestion

Renewal: Strategic Rationale
• Facilities are aging, users depend on them:
– Renew infrastructure quickly
– Have minimal impact on users
– Produce long-lasting facilities
• We know how to do this—on special projects
• What keeps us from doing it consistently
across the system?
– Lack of standard methods, specs
– Lack of reliable performance/usage information
– Human/institutional challenges
• SHRP 2 seeks to overcome these obstacles
Renewal Highlights
• Vermont Transportation Agency piloting ABC
tools in repair of bridges damaged in Tropical
Storm Irene—building local expertise
• Illinois Tollway saving $350,000 using a modular
pavement technology & guidelines from SHRP 2
• WSDOT used SHRP 2 interactive design guide
to select rehab strategy for segment of I-5:
saved 30% on agency costs, 50% on user costs
• DOT/RR Community of Interest to share/update
model agreements & best practices (7 SDOTs, 4
Class I RRs, AASHTO, Rail America, FHWA, FRA,
and Manitoba Infrastructure Transportation)
Reliability & Capacity
Capacity tackles
recurring congestion
Reliability tackles
nonrecurring congestion
Reliability Strategic Rationale
• Non-recurring events account for more
than half of congestion
– Impact of these events on users is reduced
travel time reliability (TTR)
– TTR is valuable to users
– TTR is a good tool to measure performance and
develop and target improvements
• What do we need to effectively use TTR?
– Ways to measure and monitor TTR
– Integration of TTR into modeling, planning,
programming, and design.
– Ops-oriented business practices, training
Reliability Highlights
• Multi-agency incident response training very wellreceived; FHWA using SHRP 2 material in an effort
to train 1 million responders
• Assessment tool and guide to becoming an
operation-oriented agency has been incorporated
into AASHTO SSOM web tool.
• Special session at AASHTO Board of Directors on
benefits of operations and availability of
resources for states
• Easy-to-use spreadsheet to assess effect of
design on delay and TTR, including benefit/cost
Capacity Strategic Rationale
• Sometimes you just need more highway
• Why don’t we get it when we need it?
– Multiple independent decision points that must
collectively satisfy a range of goals: engineering,
economic, environmental, community
– Decisions to be “lost” or revisited, which can
cause opposition and delay
• Facilitate and expedite key decisions: get
the right information to the right people at
the right time, avoid re-do loops
Capacity Highlights
• 8 pilot tests of tools in real projects:
– Web tool-guide for collaborative decision-making
– Integrated approach to resource conservation,
impact mitigation, expedited project delivery
• Building foundation in freight area:
– Demand modeling & data improvement strategic
plan
– Workshop on potential uses of private supply
chain data
– 2 modeling & data innovations symposia, awards
