West Virginia DOT HPMS (Case Study)
West Virginia DOT HPMS
Each year, State Department of Transportation’s (DOT’s), like West Virginia DOT, submit annual highway performance data to the Federal Highways Administration (FHWA) through the Highway Performance Monitoring System (HPMS). FHWA collects this information from State DOT’s to determine the extent, usage, condition, and performance of the Nation’s highways. This is done in an effort to assist in needs assessments and performance measures leading ultimately to the distribution of highway funds. Twice a year, State DOT’s are required to report this data (an initial report in April and a complete report in June) to the FHWA utilizing a format and collection process detailed in the HPMS Field Manual. In an effort to improve the efficiency of this task, West Virginia contracted 1Spatial to implement an automated, repeatable process using 1Spatial’s 1Integrate automated rules engine with FHWA’s HPMS rulesset to prepare their data for these submittals.

FHWA is in the midst of updating the HPMS submission process to include validation checks that will go beyond the attribute only validations of the past, to include geometric and topological checks. West Virginia’s HPMS data managers recognized the need to prioritize the update of their data management processes to be ready for these additional, more complex validations. Further, in order to successfully meet the HPMS requirements, most DOT’s must now compile data from across various departments and often in different formats.
The validity of data is critical for apportioning state funding. West Virginia DOT realized they needed to put an
emphasis on cleaning their data prior to submission. This data cleanup can be an extremely tedious manual process, taking up valuable resources from key organizational missions set to ensure safe roadways. To reduce the utilization of those resources as well as to protect against possibility for human error, West Virginia was looking for ways to automate and streamline the process, simplifying their workflow to gain efficiencies and better accommodate these new requirements.
To assist West Virginia to meet these goals, 1Spatial implemented their 1Integrate to help West Virginia DOT turn HPMS submittals into a process rather than an event. As a part of the package, 1Spatial performed an HPMS readiness assessment to ensure the data would meet the requirements of the new geospatial and y quality checks. 1Spatial’s consultants then configured and implemented the same HPMS validation rules utilized by FHWA within West Virginia DOT’s environment. In fact, the HPMS rules originally configured for FHWA by 1Spatial are being made available to all states to implement in their own environment, empowering them to leverage the rulesets within their own workflows. The automation provided by the 1Integrate rules engine, enables HPMS to become an ongoing process, minimalizing the affect on resources of the formerly mostly manual push for readiness during submission season.
Advantages of the Solution
By West Virginia implementing this solution there is no need to attempt to interpret the HPMS field manual themselves or to hire a contractor to infer what types of validation checks FHWA may be performing. The rules within the HPMS Jump Start Package are an exact copy and use the same technology that FHWA has implemented. As a bonus, 1Spatial updates the rules yearly to keep them in synchronization with FHWA’s rulesets. There is no need to use a third-party pre‐processing step or a manual process to generate the HPMS product before running the validation checks. This makes West Virginia’s HPMS submissions more of a process rather than an event. This process can be refined every year to simplify and automate the entire HPMS submittal.
State DOT’s like Massachusetts, Pennsylvania and West Virginia are implementing 1Spatial’s 1Integrate and are on their way to a more automated process for performing the HPMS validations required for next year's submission. In fact, states are also providing valuable input back to FHWA on ways the existing HPMS rules and resulting reports validation reports can be improved or tweaked to make it clearer as to where and why their data does not conform.
Some additional benefits West Virginia DOT and other State DOTs are as follows:
- Uses same validation rules and technology as FHWA to ensure the data is being evaluated in exactly the same manner
- Prepares WV to be ready for the new HPMS geospatial and topological validations
- Savings realized by ensuring the submitted HPMS data will meet FHWA requirements prior to submittal, eliminating the time consuming back and forth of data correction/resubmittal
- Efficiencies gained from a process rather than an event
