CMAQ Performance Measures

CMAQ

Moving Ahead for Progress in the 21st Century Act (MAP-21) and the Fixing America's Surface Transportation (FAST) Act required performance measures for State Departments of Transportation (State DOT) and Metropolitan Planning Organizations (MPO) to assess traffic congestion and on-road mobile source emissions for the purpose of carrying out the Congestion Mitigation and Air Quality Improvement (CMAQ) Program.

Easily access the applicability tables.

Under 23 CFR Part 490 (§ 490.707 and § 490.807), the US DOT established three performance measures for assessing the CMAQ program. These three measures are shown in the table below.

Table 1. Three performance measures for assessing the CMAQ program.

Subpart H:
