Description: Transportation Control Measures are transportation projects and related activities that are designed to achieve on-road mobile source emission reductions and are included as control measures in the SIP.
Examples that have been, or will be, implemented in the Dallas–Fort Worth area include: intersection improvements, grade seperations, signal improvements, high-occupancy-vehicle lanes, freeway-corridor management, park and ride lots, travel-demand management, ped-bike facilities, rail, and vanpool.
As TCMs are voluntary and implemented largely at local levels, no rules have been written by the TCEQ for these measures. The most recent SIP revisions in which this measure shows up are listed below.
