Highway Performance Monitoring System

The Federal Highway Administration (FHWA) requires all state transportation agencies to submit traffic monitoring data annually as part of the national Highway Performance Monitoring System (HPMS) program.  MS2’s cloud-based HPMS module allows DOTs to prepare these data submissions to FHWA with confidence and ease. The system allows users to tie traffic statistics calculated via MS2’s TCDS to any road segment on a Google map.

Estimation routines in the HPMS module can be used to report D-factor, K-factor, AADT and other traffic monitoring statistics for the entire road network.


In addition to viewing AADT and related statistics on the road network, the HPMS module also allows users to quickly view, edit and locate a complete range of detailed information on any road segment within their system, including:

  • District
  • County
  • Section
  • Functional Class
  • Highway
  • Begin/End Mile Points

HPMS is also compatible with ESRI’s Roads and Highways.

ESRI Roads & Highways Extension

Many agencies are looking to ESRI Roads and Highways (R & H) to manage their networks.  R & H provides tools to track network changes over time and can provide an agency with a central place to store GIS data.

MS2 has worked with ESRI to design an extension to synchronize GIS and traffic data allowing both TDMS and R & H to focus on what they do best.

There are two distinct components to the synchronization:

    Traffic Stations
    TDMS is used to maintain station list along with detailed traffic data associated with each traffic station.  When a user creates a new station in TDMS with the R & H Extension, TDMS automatically queries R & H to get meta-data associated with the station such as: county, community, functional class, number of lanes, speed limit, etc.  As that metadata changes over time, TDMS can automatically synchronize with R & H so TDMS traffic stations always have the latest metadata.

TDMS also maintains a list of traffic stations inside R & H that can be used via R & H for any purpose.

    Traffic Segmentation
    State DOTs are responsible for reporting HPMS and Vehicle Miles Traveled statistics.  This process requires mapping traffic station data to road segments.  The R & H extension makes managing this process easier because man network changes, like minor cartographic changes or recalibrations, can be handled without  requiring a user to review for impact to traffic data.  This allows analysts to focus on reviewing only important changes to the network.

TDMS also pushes a copy of the association between road segments and traffic stations to R & H that can be used via R & H for any purpose.
