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.
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.
17
Random Interesting Tid Bits
• 25% transportation workers are 55+ (transit 40%) Average all industries 23%. Future of Trucking
• 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!
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
29
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)
30
Data Visualization
• FHWA Data Visualization Center (DVC)
• Take spreadsheets, tables…
31
Data Visualization
and turn it into…
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

38
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.

Safety
• Sessions/Meetings/Workshops attended:
Legalization of Marijuana and the Safe Mobility of Older Drivers
Pedestrian Crossing Behavior and Safety

Safety, Horizontal Curves, and Design Speed: A Close Relationship
Using the Highway Safety Manual in the Real World
Exploring the Complexity of Pedestrian Fatality Trends: Understanding the Underlying System to Inform More Effective Action
Roadside Safety Design International Research Activities Subcommittee, AFB20(2)
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).
42
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.
