Since late 2005, The Highway Performance Monitoring System (HPMS) has undergone a Reassessment to ensure it best meets the needs of its users and customers in 2010 and beyond. The Reassessment was intended to respond to current and future business needs, address any new data needs in the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA—LU) legislation, capitalize on changing technology and where possible address resource constraints and institutional changes.
This report summarizes the changes to HPMS. The goals of this report are to:
This report is one of three documents describing the Reassessment and the subsequent changes to HPMS.
The HPMS Data Specifications document describes in detail where HPMS data are required; the frequency of data collection; data collection and reporting standards; and, any applicable metadata.
The HPMS Field Manual describes in detail the collection and reporting requirements; provides descriptions and examples for the data items; and provides more detail on internal processes such as the sample adequacy procedures and the determination of sampling confidence intervals.
From the inception of the Reassessment, FHWA undertook a very open, interactive approach. Major emphasis has been directed towards determining the data needs of FHWA’s partners, stakeholders, and customers, as well as the various uses of the existing HPMS, as well as the ability of data providers to support these data needs.
HPMS 2010+ has been refined to eliminate some no longer needed data items; include new ones to ensure that appropriate needs especially in the pavement area, can be adequately addressed; and feature a geographic data model that allows for more efficient reporting of HPMS for both data collectors and users.
The HPMS changes can be classified into three broad categories: structure, data items, and data quality/process improvement. The following summarizes the recommended changes:
While the total number of data items in HPMS are essentially the same, the number of data items that States will need to report for each section has decreased. In the new HPMS, the software will calculate 23 data items compared to 11 in the current software. Furthermore, FHWA will provide 6 data items, where previously it didn’t provide any. The following table shows the distribution of data items in the current and new HPMS.
|Data Source||Current HPMS||New HPMS|
The revision of this document in 2007 and 2008 parallels the efforts to revise the HPMS Field Manual and the Highway Functional Classification: Concepts, Criteria, and Procedures documents, and the new HPMS Data Specifications document. Both the Data Specifications and Field Manual were released as draft documents in February and March 2008, respectively.
The “final” Data Specifications is expected in September 2008. The HPMS Data Specifications will be a dynamic document that continually changes with HPMS.
The revision of the HPMS Field Manual began in earnest in December 2007. This has been a cooperative effort between the Office of Highway Policy Information, FHWA, a number of State DOTs, and several FHWA Division Offices. The draft version of the document released in March 2008 will be replaced by a final draft in the fall of 2008 and ultimately the final version in December 2008.
The availability of accurate, representative national transportation data is critical to informing decisions across all levels of transportation agencies. The Highway Performance Monitoring System (HPMS) is a key national transportation data program that provides highway inventory, condition, performance, and operating characteristics data to national, state, and regional customers. Examples of the type of data available through HPMS include pavement condition and travel by vehicle type. It is used at the national level for apportionment, performance measures, highway statistics, and conditions reporting.
The goal of the HPMS Reassessment has been to ensure it best meets the needs of its users and customers in 2010 and beyond. The Reassessment was intended to respond to current and future business needs, address new data needs in the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA—LU) legislation, capitalize on changing technology and, where possible, address resource constraints and institutional changes.
The Reassessment process began in late 2005 and will conclude with the release of this report in the fall of 2008. Critical to the success of the Reassessment has been the ongoing communication and coordination with both HPMS users and State data collectors. The outreach conducted has been extensive and resulted in an evolutionary development of recommendations related to proposed changes to the HPMS database and process.
This report summarizes the Reassessment changes and is organized as follows:
