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 2014 Standard reinforces the basic elements for bus rapid transit and makes some improvements to the earlier versions to strengthen the BRT brand.
