PLANNING FOR TEXAS' NEEDS USING HIGHWAY PERFORMANCE MONITORING SYSTEM ANALYTICAL PROCESS

The Highway Performance Monitoring System (HPMS) analytical process was developed by FHWA to assess highway conditions and estimate national highway investment needs. It is structured to provide information about the effects of alternative standards, policy strategies, and program allocations on highway needs and performance. It is capable of revealing trends in highway capacity, condition, and service as well as trends in driver safety and environmental effects of airborne pollutants. The Texas Department of Transportation used HPMS to develop its 1989 Strategic Mobility Plan. This 20-year needs assessment for 1990 through 2009 pivoted around HPMS' ability to estimate backlog needs, project rehabilitation and reconstruction needs, and augment other information about new construction and right-of-way needs. To apply HPMS in Texas, changes were made to tailor the results to reflect Texas' standards and practices. The sample size was increased to facilitate use of the model at the district level. Highway improvement costs were factored to reflect differences between national average costs and those in Texas. Rural and urban traffic growth rates were adjusted downward to be more consistent with recent growth trends and default values for minimum tolerable conditions and design standards were modified. HPMS has minimized the employee hours required to identify funding needs, provided statewide consistency in assessing needs, prevented wish-list tendencies, and allowed for the "global" assessment of funding requirements. It is a tool that allows examination of diverse scenarios and alternative uses of funds.
