Pending adoption of final USDOT rules on national transportation performance management requirements, TxDOT leadership is taking steps to begin incorporating some aspects of those anticipated requirements in state transportation plans to better prepare the Texas transportation planning community for performance-based planning.
The information below presents the TxDOT/TEMPO-endorsed set of proposed national measures for use in Texas transportation planning efforts. The charts depict the FY 2014 performance results, together with short-term (FY 2018 – the end of the current Statewide Transportation Improvement Plan) and mid-term (FY 2025 – the end of the next Unified Transportation Program) performance targets at the statewide (and urban and rural, where appropriate) level for these measures. TxDOT and its partners will, of course, adapt this set of measures when the final federal rulemaking on national performance measures is available.
Goal: To identify potential and existing safety problem areas and implement countermeasures and programs to impact the number and severity of traffic-related crashes.
The differences between FY 2014 targets and results are very minimal, due to the use of five-year moving average methodology to determine both sets of figures. While this approach allows for more consistency in relation to FHWA’s proposed measure methodology, it also serves to diminish the impact of abnormal observations in historical crash data series. For example, 2009 was an unusually-high year for both fatalities and serious injuries.
The use of the five-year average minimizes the effect of this single high reporting year for comparison purposes. The urban/rural distribution is 70% - 30%.
Fatality Rate: The fatality rate is the number of fatalities per 100 million vehicle miles traveled.
Serious Injury Rate: The serious injury rate is the number of serious injuries per 100 million vehicle miles traveled.
Performance Measure: Fatality Rate (5-year moving average)
Performance Measure: Number of Fatalities (5-year moving average)
Performance Measure: Serious Injury Rate (5-year moving average)
Performance Measure: Number of Serious Injuries (5-year moving average)
