Attached is a summary of sixth-year activities that were funded under the CMAQ program in fiscal year (FY) 1997. This report was developed by the Office of Natural Environment in consultation with the FTA. The following report summarizes FHWA's review and analysis of CMAQ information and data collected from all 50 States including the District of Columbia and Puerto Rico. Major findings include:

  • The nationwide obligation rate of CMAQ funds dropped several percentage points from previous fiscal years to 84.4 percent (down from the high of 111 percent reported in FY 1996, and 99.5 percent reported in FY 1995). However, this obligation rate is still significantly higher than levels reported in earlier years of the program (e.g., FY 1992 (42 percent) and FY 1993 (62 percent)). This funding drop may be associated with various efforts at the State and local levels to reauthorize the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) legislation during FY 1997.
  • The amount of CMAQ funds obligated for traffic flow improvements rose to higher levels in FY 1997 than in any previous year. In FY 1997, total CMAQ funds obligated toward traffic flow improvements were shown to account for 42.6 percent of the total amount of funds obligated nationwide, in comparison to 33.3 percent obligation levels for transit category. Traffic flow improvement proposals have traditionally maintained approximately 28 percent to 37 percent of historical CMAQ obligations over the past 6 years, and this year the high obligation levels may be associated with increased implementation of intelligent transportation systems nationwide.
  • For other CMAQ project categories including: demand management, shared ride, Surface Transportation Program (STP)/CMAQ, pedestrian/bicycle, and "other" programs, obligations rose slightly by 1 percent over levels reported in previous years (24.1 percent in FY 1997 vs. 23.1 percent in FY 1996). However, only one experimental project was funded in FY 1997 (located within the State of Maine) and only two were reported in last year's FY 1996 CMAQ annual report.
  • In FY 1997, approximately 768 proposals out of a total of 1178 (65 percent) CMAQ funded proposals submitted had performed some form of quantitative analysis for volatile organic compound (VOC) to demonstrate emission benefits. This is down from the number of VOC emissions analyses (75 percent) shown in previous (e.g., FY 1995 and FY 1996) annual reports.
  • The Fiscal Management Information System data used by DOT in tracking Federal-aid obligations by State compare favorably (within 4 percent accuracy) with the total cumulative obligations reported by States in their CMAQ annual reports for FY 1997.

Copies of this report have been distributed to all FTA regional offices and FHWA resource centers, and to each of the FHWA division field offices. We ask your assistance in further disseminating this report to other interested parties including metropolitan planning organizations, and other interested parties upon request.
