Sign Asset Management to Achieve Minimum Retro-reflectivity Compliance, Las Vegas Region

Mark Chang, CH2M Hill

Background: What is Retroreflectivity?

• Retroreflectivity is a measure of reflective efficiency: the level of light reflected from the surface back to the point of luminance (the vehicle headlamps) and the driver

• It is a measure of nighttime visibility

Study Overview: Four Main Tasks

• RTC Region: cities of Las Vegas, North Las Vegas, Mesquite, Boulder City, and Henderson; plus Clark County

• Advancements in asset management systems (AMS), geographic information systems (GIS), and data collection methods makes it possible to gain insights from integrating data sets

• Data availability, accuracy, and usability are key challenges that transportation agencies are struggling with to get value from safety and asset management programs

• Agencies that can connect policy, performance objectives, analysis methodology, data, and implementation will get desired benefit from their safety and asset management programs

Key Session Insights

The Great Impact of Geotechnical Features on

System Performance

Scott A. Anderson, Ph.D., P.E. Federal Highway Administration

Geotechnical Engineering Technical Services Team Manager

Thesis

• Corridors are the primary assets of a transportation agency. A transportation system will have multiple corridors.

• Geotechnical features such as embankments, slopes and retaining walls have a large influence on the performance of corridors.

• Performance (corridor or system) is the attribute agencies will be measuring and managing – and care most about.

What is a corridor?

Corridors in Wyoming

URS, WYDOT, 2010

What is a geotechnical feature?

• A geotechnical asset: slopes, walls, and embankments are examples Performance is largely attributed to soil or rock performance Does not include pits or quarries, or knowledge, such as a

subsurface information database • These are assets that are not part of corridors

– “Geotechnical Assets”

What is “performance”?

• Many definitions concurrently • Our ultimate objective(s) • Something that can be measured • Something that can be managed

USDOT Performance Report

Condition Reporting

Report to Congress • System Conditions • Operational Performance • Safety • Revenue and Expenditures • Investment Analysis

Difficult to associate performance with federal investments

Performance Management in the Future

Performance Management of the Federal Highway Program is a systematic approach to making investment and strategic decisions using information about the condition and performance of the system and developing an approach to achieve a desired set of national goals

For a system to perform well, its corridors must perform well and deliver mobility, capacity, efficiency, reliability and safety

One broken link can change all of that

Geotechnical Message

• Consider 200 slopes, 10 walls and 50 embankment culverts identified as ‘in need’ by separate inventory and assessment methods Measure: reduce number Target: 10% reduction

• Consider 10 corridors of primary significance Measure: safety, efficiency, mobility Target 10% improvement

Geotechnical Message • It is important to be developing tools and

practices for data collection and decision making

Geotechnical Message • It is also important to be looking beyond – to how

that contributes to improved performance of a system through performance of a corridor Bridges Pavement Walls Signs Slopes Embankments Tunnels Etc.

Recent U.S. examples • Embankment on I-75 in TN

March 8, 2011 1-2 lanes will be closed for almost

6 months Repair of $9.4 – 12.6M 150 ft high embankment CMP culvert

• Deterioration • Separation • Saturation • Weakening • Failure

Recent U.S. examples • Rockslide on I-40 in NC

October 2009 6 month closure 25,000 ADT $10M repair* $ 65M travel time costs* $57M operating costs* $44M congestion costs* $10M other costs*

*HDR, 2010

Recent U.S. examples • Rockfall on I-70 in CO

Incorporating Geotechnical Assets into Transportation

Asset Management

“The STIP is really an investment guide more than a spending plan. The improvements that we construct today and plan for tomorrow must be managed as assets and preserved for future generations. We must become as skilled at optimizing the lifecycle costs and overall performance of our transportation assets as we have traditionally been at engineering and building them.”

Asset Management Programs Under Way at AKDOT&PF

• Geotechnical Assets include: slopes, embankments, material sites, retaining walls, rock bolts, tie-back anchors, rockfall mesh, etc.

• Some are visible, some are buried – creating management difficulties.

What is Geotechnical Asset Management?

• Materials Site Inventory Under way

• Unstable Slope Management Program Under way

• Retaining Wall Management Program Just beginning

• Unstable Embankment Management Program Pretty iffy

Final Thoughts

• Focus on features can lead to stovepipes

• Focus on corridors requires integration

• Geotechnical features are not ‘solid as rock’ – there are ownership responsibilities

• System performance is limited by the weakest link, which may be geotechnical
