Description of Methodology Used
This report contains the top 5% of projects, by category, programmed in the most recent Texas Federal Highway Safety Improvement Program (HSIP). Projects were ranked in six separate categories using the Safety Improvement Index (SII). In its most basic form, the SII is the ratio of the cost of crashes that have occurred at a location to the cost of constructing the proposed improvement. The SII incorporates adjustments to provide additional benefit for:
- locations experiencing increasing traffic over the project life
- improvements that will reduce maintenance costs
- projects expected to have long service lives over which construction costs can be amortized
The six categories looked at were:
- Grade Separations
- Left Turn Lanes
- Median Barriers
- Widening
- Miscellaneous Hazard Elimination Improvements
- Off-System Improvements
There were 291 total projects programmed. The above table represents the top 5% of each category that has not already been let to contract.
Extent of public road coverage
The most current HSIP that these locations were selected for funding in was open to improvements on all public roadways.

Years used in data analysis
The most recent 3 years of crash data for Texas was used in the data analysis: 1999 - 2001. All levels of crash severity were used with Fatal and Incapacitating crashes being weighted the heaviest in regards to crash cost.
