Cost-Effectiveness Analysis Tools

This page last reviewed February 20, 2020

The following tools enable staff and decision-makers to quantify the cost-effectiveness of proposed projects in terms of cost per pound (or ton) of pollutants reduced.

These tools are used to evaluate projects and to report on two programs in particular: the Motor Vehicle Registration Fees Program and the Congestion Mitigation and Air Quality (CMAQ) Program.

Automated Methods to Find the Cost-Effectiveness of Funding Air Quality Projects

This automated Access database program includes methods for the following project categories: cleaner on- and off-road vehicle purchases and re-powers; cleaner street sweepers; new bus service operations; vanpool and shuttle service; traffic signal coordination; bicycle facilities; telecommunications; and ridesharing and pedestrian facilities.

Over the next several weeks the Generic Methods Program will be updated to reflect the use of PM2.5 emission rates and to update the list of nonattainment areas in the input screens. Users can continue to use the existing Generic Program since the revisions are only to field labels and titles. The calculations that the program makes will remain the same. Users can edit the resulting reports if desired to reflect the pollutants being estimated. Alternatively, users may use the Methods Guide (Word document, below) in conjunction with a spreadsheet program and Emission Factor Tables to estimate cost effectiveness.

South Coast Only
The following database program should be used by SCAQMD as they contai n information specific to local governments in the Southern California region. SCAQMD users should use the emission factor tables below.

Emission Factor Tables

These emission factor tables are to be used in both the generic and the SCAQMD programs.

This PM Size Fraction table should be used to express PM2.5 reductions as PM10.

Methods to Find the Cost-Effectiveness of Funding Air Quality Projects

This Word document includes methods and examples for evaluating motor vehicle registration fee projects and congestion mitigation and air quality improvement projects.

This is a hardcopy version of the “Automated” methods above. The May 2005 version may be used in conjunction with the May 2013 emission factor tables above. (Note: The emission factors used in the examples in the May 2005 version are out of date. The methods and formulas are still current.)

Determining the Cost-Effectiveness of Employer TDM Programs

This automated Access database was prepared to assist employee transportation coordinators assess the cost-effectiveness of employee rideshare programs where a week-long commute travel survey is used to gather vehicle trip-related data. (For a Microsoft Word version of Ridehsare Program evaluation methods, see Pages 39-47 of the Methods guide above.
