Trip Reduction Program

Why was the program created?

The Trip Reduction Program (TRP) began in the late 1980s as part of the State of Arizona’s response to a court ruling requiring greater efforts to reduce air pollution. One outcome of the ruling was the legislation of Travel Reduction Program state statutes that focuses on employers and schools because the approximately 80 million commuter miles driven each weekday are a significant contributor to regional air pollution (carbon monoxide, ozone, particulate matter). Subsequent revisions to the statute and related Maricopa County ordinance (P-7) reduced the minimum employee site count to 50.

What are the goals of the program?

Employers and schools are asked to reduce single occupant vehicle (SOV) trips and/or miles traveled to the work site by 10 percent for a total of five years, and then 5 percent for three additional years, or until a 60 percent rate of SOV travel is reached. Progress is tracked through an annual commute survey of employer/school sites. The results of the survey are used to develop an annual plan that commits the employer / school to implementing and documenting various strategies to reduce SOV trips or miles.

How does the Trip Reduction Program help an employer or school with compliance?

  • Provides questionnaires for the commute survey

  • Generates a commute analysis for each site surveyed

  • Reviews plans submitted by employers/schools

  • Recommends approval/rejection of plans

  • Monitors implementation of approved plans

  • Reports on the costs of implementing plans

  • Generates annual report on commute-related emissions

What is the Trip Reduction Task Force?

The Maricopa County Board of Supervisors appoints up to 15 qualified candidates to serve two-year terms on the Travel Reduction Program Regional Task Force.

The Task Force meetings are open to the public and are usually held every four weeks. It’s during those meetings that employer/school survey results are reviewed and the related plans are officially approved or rejected. In addition, the Task Force will examine reports from TRP office staff on compliance delays and determine if enforcement action should be initiated.

While fines are very rare, failure to comply with a Task Force request can result in civil penalties of up to $300 per day. Failing to meet the SOV targets is not a reason for an organization to be fined.

What other assistance is available?

The Maricopa County Trip Reduction Program partners with Valley Metro Commute Solutions to provide training, personalized assistance and promotional materials to all participating organizations.
