This project builds off NCHRP 20-65 Task 21, which focused on reviewing existing BRT projects and the methods used to evaluate their costs and benefits. NCHRP Project 20-65 Task  22 is intended to provide transportation agencies with a methodology and a guide for evaluating the potential benefits of converting a mixed-flow lane to exclusive BRT use. The benefits and costs of converting a lane to a BRT lane will depend heavily on how such a project affects traffic speed, delay, and vehicle miles traveled, both in the mixed flow lanes and the BRT lane. The benefits will also depend on the extent to which improved transit service results in mode shift to transit. Thus, a critical section of the report is the description of the  analytical methods and assumptions used for these calculations. This report includes a  demonstration of a methodology that captures all the benefits (and disbenefits) across transit riders and auto drivers. The intended audience for this report includes transportation planners and modelers, consultants, professionals involved in economic, social, and environmental impact analysis, and others involved in evaluating projects, as well as decision makers who use the results of the analysis. The report is intended for those who have some knowledge of cost/benefit analysis and would like more information about how to apply it when converting a lane for the use of transit at a corridor, local, or regional scale.
