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.

"The Hopi Senom Transit Program has been operating for the past twenty-two years to provide public transportation on the Hopi Reservation and local border towns to the general public and employees of local governmental and private sector agencies. The service area includes the Hopi and Navajo reservation areas and Flagstaff. Boundaries and major communities of the area served is Keams Canyon, Tuba City, Flagstaff, Leupp and Kykotsmovi. Currently, the Hopi Senom Transit Program operates two fixed routes providing service five days a week. Service is provided on schedule between Kykotsmovi and Moencopi, and Kykotsmovi and Keams Canyon. Vanpool transportation for Tribe employees is provided Monday through Thursday between Flagstaff and Kykotsmovi. This vanpool style service is open to the general public, but is used primarily by Tribe employees. The Public Transportation Section of the Multimodal Planning Division of the Arizona Department of Transportation is charged, among other roles, with administering transit programs including the Section 5311 Rural Transit Program ... The Five-Year Implementation Plan will provide a roadmap for transit services on the Hopi Reservation. In addition, a matrix of tasks and responsibilities will provide a framework for the Section 5311 Program to maintain management oversight of the rural transportation programs. This framework will become a key part of the evaluation process for future funding cycles"--Pages 1-2

"This guidelines and procedures manual is intended to be used by the staff of the Arizona Department of Transportation (ADOT) and Arizona's regional transportation planning agencies, which include Councils of Governments (COGs), Metropolitan Planning Organizations (MPOs), and Transportation Management Areas (TMAs). In addition to outlining the guidelines and procedures for regional transportation planning functions, this manual provides an overview of the programs administered by the ADOT Multimodal Planning Division (MPD)."--Introduction, Page 1-1

Project Summary

Passing and climbing lanes provide additional lanes for vehicles to safely pass other vehicles while maintaining speeds. Implementing passing and climbing lane projects provides traffic operational and safety benefits at a cost that is far less than fully widening a highway. In an effort to enhance safety and mobility on Arizona's roadways, the Arizona Department of Transportation is currently updating the 2003 Passing and Climbing Lanes Prioritization Study. This update intends to further refine the identification and prioritization methodology previously utilized and to develop a prioritized list of candidate locations that would provide the most benefit to the traveling public.
Study Objectives

    Review previous studies and research current best practices.
    Analyze the safety and performance benefits of passing/climbing lanes constructed since the previous study.
    Develop a revised methodology and ranking criteria.
    Obtain feedback from ADOT District Engineers and other stakeholders, such as rural COGs and MPOs.
    Develop a new prioritized list of candidate passing/climbing lane projects.
