The Highway Performance Monitoring System


What is hpms
What is HPMS?

  • National highway transportation system database

  • Data on highway conditions, performance, and usage

  • Analytical products such as VMT estimation

  • Primary source of information for distributing Federal-aid funds


What is hpms1
What is HPMS?

Contains data on our Nation’s highways

  • Extent - mileage

  • Condition - IRI, PSR

  • Performance - traffic/pavement

  • Use - VMT

  • Operating Characteristics - V/C


Scope of the hpms
Scope of The HPMS

  • A nationwide inventory system that includes data for allof the Nation's public road mileage

  • Annually certified by each State’s Governor

  • Includes facilities both on and off State-owned highway systems

  • Each State is required to furnish annually all data requirements specified in the HPMS Field Manual.

    HPMS VMT Estimates


    The highway performance monitoring system

    What is VMT? authority … open to public travel … available, except during scheduled periods, extreme weather or emergency conditions, passable by four-wheel standard passenger cars, and open to the general public for use without restrictive gates, prohibitive signs …

    • VMT = Vehicle Miles of Travel

      = AADT x segment length

    • It is an additive measure of cumulative travel

    VMT Estimation authority … open to public travel … available, except during scheduled periods, extreme weather or emergency conditions, passable by four-wheel standard passenger cars, and open to the general public for use without restrictive gates, prohibitive signs …

    • Can be calculated for State Systemwhere traffic counts are relatively comprehensive

    • Estimated for HPMS using Sample expansion (until Reassessment)

    • Stratified by Urban, Rural, Small Urban areas

    Hpms vmt estimation
    HPMS VMT Estimation authority … open to public travel … available, except during scheduled periods, extreme weather or emergency conditions, passable by four-wheel standard passenger cars, and open to the general public for use without restrictive gates, prohibitive signs …

    • Entire VMT estimation for Federal Aid roads has been based on Sample data (all other traffic counts ignored)

      • Will be changed to full calculation of Federal Aid VMT this year

    • Non-Federal Aid VMT (FC 08, 09, 19) based on adjustment of prior year VMT estimate


    Vmt accuracy
    VMT Accuracy authority … open to public travel … available, except during scheduled periods, extreme weather or emergency conditions, passable by four-wheel standard passenger cars, and open to the general public for use without restrictive gates, prohibitive signs …

    • Within HPMS, accuracy is affected by Sample “adequacy” and quality of “current year estimates” of AADT

    • Local VMT is more challenging given the difficulty of measuring both baseline traffic and growth


    New approach to vmt hpms reassessment
    New approach to VMT – authority … open to public travel … available, except during scheduled periods, extreme weather or emergency conditions, passable by four-wheel standard passenger cars, and open to the general public for use without restrictive gates, prohibitive signs … HPMS Reassessment

    • Traffic counts “required” on all Federal Aid eligible roads

    • VMT estimation is straight calculation

      • No Sample “expansion”

    • Local VMT is still an off-line estimate

      • Local VMT typically not used in Fed Aid formulas


    Required traffic counts
    “Required” Traffic Counts authority … open to public travel … available, except during scheduled periods, extreme weather or emergency conditions, passable by four-wheel standard passenger cars, and open to the general public for use without restrictive gates, prohibitive signs …

    Percent FA with counts


    Required traffic counts1
    “Required” Traffic Counts authority … open to public travel … available, except during scheduled periods, extreme weather or emergency conditions, passable by four-wheel standard passenger cars, and open to the general public for use without restrictive gates, prohibitive signs …


    Current year estimates
    “Current” year estimates authority … open to public travel … available, except during scheduled periods, extreme weather or emergency conditions, passable by four-wheel standard passenger cars, and open to the general public for use without restrictive gates, prohibitive signs …

    • Non-current counts adjusted to current year using “Matrix” process

      • 15 year table of actual traffic counts

      • Regression analysis to develop growth rates by Functional Class by Region

      • Rates applied to last actual counts

    • “Average” rate for 2009: 0.5-0.6%/yr


    Vmt old process vs new daily vmt on federal aid stp eligible roads
    VMT authority … open to public travel … available, except during scheduled periods, extreme weather or emergency conditions, passable by four-wheel standard passenger cars, and open to the general public for use without restrictive gates, prohibitive signs …– Old Process vs New Daily VMT on Federal Aid (STP) eligible roads

    VMT Growth

    Old rate: -0.2%

    New rate: -1.6%


    To reflect current growth
    To reflect current growth: authority … open to public travel … available, except during scheduled periods, extreme weather or emergency conditions, passable by four-wheel standard passenger cars, and open to the general public for use without restrictive gates, prohibitive signs …

    • Improve data collection rate options

      • Tighter control of contract schedules

      • Shorten traffic count cycles

    • Increase # stations counted annually

      • Set of short count stations, such as HPMS Sample approach

      • Increase number of continuous counter


    Cost implications
    Cost implications authority … open to public travel … available, except during scheduled periods, extreme weather or emergency conditions, passable by four-wheel standard passenger cars, and open to the general public for use without restrictive gates, prohibitive signs …

    • Requires additional staff for:

      • Count processing

      • Contractor liaison and administration

      • Payment request processing


    Impact of higher growth rate
    Impact of higher growth rate authority … open to public travel … available, except during scheduled periods, extreme weather or emergency conditions, passable by four-wheel standard passenger cars, and open to the general public for use without restrictive gates, prohibitive signs …

    • Matrix produced a 0.5 to 0.6% rate

    • Recalculated VMT in new 2009 HPMS file using a 1% growth rate

    • Result showed a 0.1% difference in total VMT using a 1% annual growth rate for all counts older than 2009

    • Conclusion: counts are sufficiently current to reflect recent trends in VMT total, but still may not give desired “annual” picture
