Traffic Data Management System (TDMS)

Our Traffic Data Management System (TDMS) is the central repository for local traffic counts within the SEAGO region. Traffic counts stored in this database were collected and provided to SEAGO by our local jurisdictions and by consultants specializing in traffic data collection. The Traffic Data Management System is updated immediately when an agency uploads a recent count to the system. Each count was taken during a continuous 24-hour period, beginning on the date indicated. Counts longer than 24 hours were divided into distinct 24-hour intervals and stored in the database as separate records.

Requests for traffic count data collection should be directed to Chris Vertrees at cdvertrees@seago.org or John Merideth at jmerideth@seago.org

Traffic Data Collection Program (TDCP)

The SEAGO Five-Year Strategic Plan (2017-2022) identified the development of an internal traffic count program as the top priority for the SEAGO Transportation Program.  The strategic planning committee felt that building this capacity internally will eliminate the costs associated with contracting with a consulting firm to gather this data, and would reduce agency data collection costs.  The purpose of the SEAGO Traffic Count Program is to:

·  Assist local member agencies through the collection of traffic count data to support transportation plans, traffic studies/analyses, grant applications, and road maintenance programs.

·  Support local roadway functional classification requests.

·  Provide fee-based services to non-member public and private entities to support economic development activities.

·  Support ADOT HPMS program.

Highway Performance Monitoring System (HPMS)

Starting with Calendar Year 2018, ADOT assumed the responsibility of collecting all HPMS data for the state, including HPMS data associated with local government roads. For more information involving ADOT’s HPMS program please click HERE. 

Functional Classification

Functional classification is the grouping of highways, roads and streets by the character of service they provide and was developed for transportation planning purposes. More detailed information about functional classification be found HERE.

In 2013/2014, SEAGO, along with our member agencies conducted a comprehensive review of the federal functional classification of all roadways in the region. To view the results of that effort, please click HERE.
