CMAP is developing performance measures, internal processes, and partnerships with other agencies to assure that transportation funds are not allocated based on arbitrary formulas, but on performance data. A performance-based funding system will be more likely to identify and mitigate transportation system deficiencies than fixed allocation processes. CMAP is committed to working with implementers to develop a transparent programming process that allocates funding efficiently to maintain a world-class multi-modal transportation system. For more information, see CMAP's summary of the performance-based funding concept. Transportation performance measures and their application to improve the programming processes for the region are key elements of CMAP's Congestion Management Process
Expressway Atlas. In addition to the performance measures below, researchers and the public may be interested in the 2012 Expressway Atlas and its 2014 Update. The Atlas includes system data, daily and monthly factors, AADT tables, hourly percent tables, and detailed traffic flow graphics. The 2014 Update includes updated graphics of the link-by-link and ramp-by-ramp traffic volume estimates using highly detailed corridor-level drawings.
