TPICS is a tool for planners to use in early-stage policy/strategy development, “sketch planning”,
and public hearings processes. It contains 100 CASE STUDIES DOCUMENTING THE BEFORE-ANDAFTER ECONOMIC AND DEVELOPMENT CONDITIONS associated with real-world highway &
intermodal projects.

T-PICS (SHRP C03) provides an “early stage” assessment of economic impacts but is not based on local traffic conditions.
•
More advanced “middle stage” analysis requires inclusion of traditional factors such as travel time, travel cost, and
safety. In addition, wider economic impacts can be derived from changes in reliability, connectivity and accessibility.
•
The SHRP C11 study addresses these “wider economic impacts” with 3 spreadsheet tools that measure a project’s
impact on (1) travel time reliability, (2) market access, and (3) intermodal connectivity. The study also includes (4) an
accounting system tool that converts these measurements into economic benefits and impacts.

T-PICS Case Detail
1. TRAVEL TIME RELIABILITY
T-PICS My Project Tools
Estimating the impact of congestion reduction on reducing “nonrecurring” delays that leads to wide variability in travel times
Estimating the value of improved access to an
intermodal center
Example: Preventing a missed flight
• Median drive time: 30 minutes
• With incident delays: 2 hours
Example: Midwest agricultural state – expansion
of export commodities
• Rail or Barge
• Which one should you improve access to?
Trips (in 000's)
Estimate of benefit based on characteristics and access:
• Volume, Value of goods, and Origins & Destinations served
• Ground access (distance and time)
