What is TRB?
TRB (Transportation Research Board) One of seven program units of the National Academies of Sciences, Engineering, and Medicine
• Promote National Transportation Research
http://www.trb.org/AboutTRB/AboutTRB.aspx
• Alaska pays dues so all staff can get an account to log in and get access to annual meeting papers, publications and extensive library

Performance/Asset Management
• DOTs are a mobility company: Safety; Flow; Accessibility; Sustainability.
• Performance measures help to prioritize what is important and what knowledge is needed. More coming.
• Making AM the new normal. Too much $ for all GOOD.
• Risk/Vulnerable assets new challenge
• Resilience – Strategic divestment letting assets go…Maintenance is key.
![Page 16: Alaska Department of Transportation & Public Facilities · Our mission is to Keep Alaska Moving through service and infrastructure.

16
Resilience
• How can you prevent today’s solutions from becoming tomorrows problems.
Extreme weather events/climate change. Divest/Coastal defenses. Design&Maintain – Design Safe to Fail
• Internationally – Immature-No rail/only highway. Crop production main freight. Alaska? Oil/Fishing. Other freight modes are low. Trying to get private sector investment. Defensive Innovation transformations/Design takes account events. Ei flooding.
• New Jersey Design caused problems. Lack of Maintenance. Need to integrate with other management systems.

• 40% of morning congestion caused by school traffic
• US population will double in 40 years. Can’t build out.
• Data Modeling. “All Models are wrong, but some are useful”
• Kentucky increase 3.3 degrees F in next 20 years and 5.6 in the following 20 years.
• Wash State sued and must correct Fish Passage by 2030 cost $3.73 Billion. Habitat Connectivity requirement. Air emissions.
• Doing something different doesn’t make it better.

Data Governance
• Other states have similar challenges
Silo’d data, need for new systems/data, duplication of systems, cyber attacks, shifting priorities, etc.
• Governance reduces chaos-
manage data & application prioritization process
align business and technology strategy
• Governance at the forefront- with Asset Management implementation, Performance based management approach- Must have quality data!
![Page 28: Alaska Department of Transportation & Public Facilities · Our mission is to Keep Alaska Moving through service and infrastructure. Alaska Department of Transportation & Public Facilities](https://reader033.vdocuments.mx/reader033/viewer/2022042308/5ed473c264cb9d0fda746e67/html5/thumbnails/28.jpg)
28
Data Governance
• Approaches to governance:
Set expectations of behavior – no silos, need for newest technology
Look at business needs statewide
Look at data & technology as an “enterprise asset”
Be flexible- no one size fits all
Need resources- IT, funding, staff
Need broad support
![Page 29: Alaska Department of Transportation & Public Facilities · Our mission is to Keep Alaska Moving through service and infrastructure.

Data Governance
• MN DOT –focus on “Information Governance”
• Ohio DOT- “tricked” data managers into governance by recommending central database.
• Florida DOT- “Technology Strategic Plan”
• FHWA- implemented Data Governance- reduce duplication of applications- do less with more (tighter budgets)

32
Other topics
• Asset Management- States face challenges with implementing, programming into STIP, documenting criteria, getting away from “worst first” concept.
Essential to AM:
• GIS- need for central mapping database, making it accessible. Ex. TIMS- Transportation Information Mapping System
• Data Governance
• Machine Learning- Develop software models to predict conditions, it “learns” as it discovers new variables.
• Data Scientists- seems to be the big buzzword- DOT’s hiring them to make/support business decisions

The Take-Away for TRB Newbies:
• There’s a lot going on: ~50 lecture sessions and ~40 meetings at any given time. You want to be in 5-10 different events at once.
• The lecture sessions are hit & miss-some are great, some not, many are “bait & switch”-not what you expect.
• The committee and subcommittee meetings can be fascinating, and there are opportunities to interact and network. The presentations tend to be shorter, but better.
Meetings in a subject area of your expertise and interest are probably a better use of your time than random lecture sessions. Try some.

41
Safety (Cont.) Legalization of Marijuana and the Safe
Mobility of Older Drivers
Takeaways:
NHTSA conducted a roadside survey in 2013-14 on alcohol and drug use.
Drug presence doesn’t necessarily equate to impairment. Many drug categories lead to difficult data analysis.
Not close to having a roadside test similar to alcohol.
Older drivers are the fastest growing licensed driver group nationally and tend to have multiple medications in their system (prescribed and non-prescribed).

Safety (Cont.) Speed Limits 2019: Current Perceptions,
Technologies, and the Future
Takeaways:
• Recent survey conducted by National Committee on Uniform Traffic Control Devices Task Force reviewing modifying speed studies to rely less on 85th percentile and more on Pace.
• Speed feedback sign study concluded that they can safely be installed on arterials as a speed treatment without impacting operations.
