| 摘要： | The Highway Safety Improvement Program (HSIP) aims to achieve a reduction in the number and severity of fatalities and serious injury crashes on all public roads by implementing highway safety improvement projects. The Texas Department of Transportation (TxDOT) requests TxDOT districts propose HSIP projects through an annual statewide program solicitation. TxDOT’s HSIP is based on a robust benefit-cost ratio analysis, yet there are several areas for improvement. As national safety assessment methods have evolved, legislation mandates that the use of safety performance methods be elevated. The increased use of advanced safety assessment methods and tools can help a state determine locations and safety improvements that have the greatest potential to reduce fatal and injury crashes while minimizing the influence of unstable crash trends over many years. This project addresses how TxDOT can: (1) Allocate funds in the most cost-effective manner. (2) Create a level playing field for all districts participating in the HSIP and promote district participation in the process. (3) Minimize the amount of time and resources required to identify HSIP projects. |
