The BRT Standard is an evaluation tool for world-class bus rapid transit (BRT) based on international best practices. It is also the centerpiece of a global effort by leaders in bus rapid transit design to establish a common definition of BRT and ensure that BRT systems more uniformly deliver world-class passenger experiences, significant economic benefits, and positive environmental impacts.
The BRT Standard evaluates BRT corridors based on a wide range of metrics to establish a common definition of BRT through the BRT Basics, and recognizes particularly high-quality corridors with either Bronze, Silver, or Gold rankings.
