Moving people and goods by air, water, road and rail. The degree to which transportation infrastructure systems serve the US economic and business community
- bjectives.
In 2000, The World Bank projected the world economy to grow 33% between years 2000 and 2010, increasing from $31.8 trillion to $40 trillion.
It reached $60.5 trillion in 2008 ($78.9 trillion in 2011 est).
By the year 2050, the world economy is projected to increase to between $135 trillion to $216 trillion. Are our infrastructure systems ready for the growth? Are the investments in US infrastructure adequate?
Transparency Accountability Gaps
› Currently no “rigorous” index for measuring US
infrastructure, specifically in relation to economic growth
› Need a well-defined methodology for creating an
index
› Existing methods for creating indices should be
applied
Develop methodology for constructing a US
Transportation Performance Index (TPI)
› Repeatable › Transparent › Use to evaluate trends in infrastructure
performance
Main goal of index: measure the effect of
infrastructure performance on economic prosperity

How well service is provided? Efficiency- the cost of service Does the service provide full value for cost? Utilization- whether growth can be

Indicator #9 Highway Congestion Definition: The travel time reliability is measured by the Travel Time Index (TTI) which is the ratio of peak period travel time to free flow travel time. Why it’s important: The TTI expresses the average amount of extra time it takes to travel during peak hours relative to free‐flow travel. A TTI of 1.3, for example, indicates a 20‐minute free‐flow trip will take 26 minutes during the peak travel times, a 6‐minute (30 percent) travel time penalty. Criteria metric: Quality of Service Historical Values: Observations: Congestion problems tended to be more severe from 1990 to 2007 in large urban
- areas. The average increase in the travel time was about 10% during this period.
As economy goes down, travel time indices slightly decrease in 2006 and 2007, probably due to less traffic on the highways. Contribution to Index: MSA type 00 (population under 1 million without primary airport) – 0.000 MSA type 01 (population under 1 million with primary airport(s)) – 0.000 MSA type 11 (population over 1 million with primary airport(s)) – 0.113 The weight factors are determined and calculated from Analytical Hierarchical Process based on a survey of U.S. Chamber members.

Step 1 – Normalize the data
› 1 is desirable and 0 is undesirable › 2000 as the base year
Step 2 – Correlate indicator to type of MSA
› Adjust indicator weights to reflect the fact that not
all data is collected for all MSAs in the sample
Step 3- Compute index
› For each MSA type
For each MSA
For each indicator

environmental influences has on the relationship between GDP per capita and TPI at the state level.
Used Data Envelopment Analysis to compute
an efficiency score for each state.
Environmental adjustment (population, density,
growth, usage)
Outputs – ln GDP per capita Inputs – debt, life expectancy
Delaware’s
comprehensive efficiency stayed constant, being a benchmark for all 3 data years or having an efficiency value of 1.00. The TPI for Delaware for the data years are:
- 1995: 54.70, 34th Rank
- 2000: 57.11, 28th Rank
- 2007: 57.43, 35th Rank
