Given the context for BRT planning in the Valley, this project, the Comprehensive Arterial Bus Rapid Transit Planning Study, is tasked with identifying demand for BRT and defining operational characteristics, capital infrastructure needs, and fleet requirements. The study considers how operational characteristics and needs of the BRT corridors may change as the regional transit network develops over the life of the 20 year transit program.

The Multimodal Planning Division (MPD) of the Arizona Department of Transportation has been tasked with identifying corridors throughout the state where improvements to the transportation infrastructure supports the greatest potential commercial and economic benefits. These "Key Commerce Corridors" represent a strategic statewide approach to leverage infrastructure improvements to enhance Arizona's competitive economic position. This document presents the basis for the identification and evaluation of the Key Commerce Corridors.
