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.

The Office of Highway Safety produces the annual Highway Safety Plan to serve as the implementation guide for highway safety projects throughout Arizona. The Plan also is an application for funding through the National Highway Traffic Safety Administration. Project selection is data driven and utilizes state and national traffic safety data (e.g., crashes, fatalities, injuries, citations, etc.). Knowledge of the Arizona political, economic, and demographic environments, as well as highway safety expertise on the part of staff and other partners also are taken into account where appropriate.

The Arizona Department of Transportation has been involved with railroad planning since 1976, with its first State Rail Plan Update issued in 1978. The most recent report, the 2000 Arizona State Rail Plan Update was an important starting point for this Inventory and Assessment in that the seven-year-old study provides the description and inventory of Arizona railroads as they existed at that time. There have been a number of important changes over the intervening years, and these are reflected in this 2007 Inventory and Assessment. In addition to the 2000 State Rail Plan Update, RLBA made use of the 2003 Maricopa Association of Governments (MAG) High-Capacity Transit Study and the 1998 Arizona High Speed Rail Feasibility Study. The information contained in this report was gathered from a number of sources, including the railroads themselves, ADOT, the Arizona Corporation Commission, MAG and numerous Arizona officials. A listing of persons who contributed to this Railroad Inventory and Assessment is provided under “Acknowledgements” inside the front cover. Information in this report also was obtained from the Association of American Railroads and from RLBA’s extensive data banks.

The Arizona Department of Transportation (ADOT) Roadway Departure Safety Implementation Plan (RDSIP) has identified tree removal as a feasible countermeasure to reduce roadway departure crash frequency or severity.

The Arizona Department of Transportation (ADOT) Roadway Departure Safety Implementation Plan (RDSIP) has identified tree removal as a feasible countermeasure to reduce roadway departure crash frequency or severity. Previous ADOT work has identified locations for tree removal, and activities to conduct this work are underway. To test the safety effectiveness of removing the trees, ADOT intends to conduct statistically rigorous before-after safety effectiveness analysis to estimate state-specific crash modification factors (CMFs).
