LCCA and RealCost in Map-21/TPM

• LCCA – Economic Analysis

– Compares Different Alternatives

– Discount Rates

• What Do you need? – Agency costs

Design, Activity timing,

Benefit-Cost Analysis An Investment/Economic Analysis Tool


March 25, 2013

Nathaniel D. Coley, MBA

Structural Engineer/Economist Office of Transportation Performance Management

Why Investment/Economic Analysis?

• System demands far outweigh available & expected resources

• Links accountability to decision making

• Proven process for evaluating alternatives

• MAP-21 Requirements “link investments to outcomes”

– Investment Plans

– Performance-Based Plans

– Financial Plans

11

Bridge/Pavement Investments

Emissions Reductions

Congestion Reduction

Crash Modification

Factors

Other Areas

12

Analyzing Transportation Decisions

• We typically evaluate objectives individually but

program projects as a package of objectives

13


Overall Project Merit

• We need to evaluate investment decisions on a

project by project bases considering all factors

For public agencies benefit‐cost analysis results describe ROI. Traditional benefit cost analysis and ROI analysis for transportation includes user benefits (time, cost, safety) for travelers and select environmental effects (air, quality, noise) along with capital, operations, and maintenance(O&M) costs.

HSM and Related Analysis Tools


March 25, 2013

Esther Strawder Safety Specialist, FHWA- Office of Safety

28

What is the HSM?

• The HSM is a tool for estimating safety performance of design and traffic control elements being evaluated in the project development process

• The HSM introduces a science-based approach that allows safety to be quantitatively evaluated alongside traffic operations, environmental impacts and construction costs

• Provides analytical tools and techniques for quantifying the potential effects on crashes as a result of decisions made in planning, design, operations, and maintenance

How do the tools relate to HSM?

• Safety Analyst provides a set of

software tools used by state and local highway agencies for the highway safety management process documented in Part B of the HSM

• Safety Analyst can be used by highway agencies to improve their programming of site-specific highway safety improvements.

• The IHSDM Crash Prediction

Module (CPM) provides a faithful software implementation of the crash prediction methods documented in Part C of the HSM

• IHSDM is a suite of software analysis tools for evaluating safety and operational effects of geometric design decisions on highways
