139 TRAFFIC/ROADWAY AGENCY SURVEY TCRP J-7/SA-22 - Bus and Rail Preferential Treatments in Mixed Traffic Environments This page shows all the questions on a single page to help your agency determine who should answer the survey. When you are ready to begin the survey, use the link here or at the bottom to go back to the start page Page 1 Tran sit Preferential Treatment Application s You will be asked to review a table of all transit preferential treatments that the transit agency has implemented. You are only asked to update information on treatments within your jurisdiction. A sample treatment is provided below.
