Transportation Conformity - Project Analysis

A localized analysis of traffic and air quality impacts (i.e., hot-spot analysis) is performed for individual projects that are:

  • Regionally significant projects included in a conforming TIP/RTP that meet certain criteria
  • Newly conceived projects unable to be included in the current TIP/RTP
  • Started after the three-year time limit lapses for a project found in conformity

Carbon Monoxide (CO) analysis is required for:

  • Projects at sites which are identified as possible violation sites
  • Any projects affecting one or more of the top three intersections in terms of traffic volume
  • Worst level of service
  • Project affecting intersections at Level of Service D, E, or F

Particulate Matter less than either 2.5 or 10 microns in diameter (PM2.5 and PM10) analysis is required for:

  • New or expanded highway projects that have a significant number of or significant increase in Diesel vehicles
  • Projects affecting intersections at Level of Service D, E, or F because of increased traffic volumes from a significant number of Diesel vehicles
  • New or expanded bus and rail terminals which increase the number of Diesel vehicles at a single location
  • Expanded bus and rail terminals and transfer points that significantly increase the number of Diesel vehicles congregating at a single location and
  • Projects in or affecting locations, areas, or categories of sites which are in the PM2.5 and PM10 applicable implementation plans or implementation plan submission as sites of violation or possible violation.
