"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

The study objective was to identify a lighting system which has a lower power cost and reduced maintenance requirements and which provides adequately for motorists' needs in terms of legibility and illumination level. Twenty-five candidate lighting systems were identified through a review of technical data and specifications for lamps and fixtures by an independent lighting expert. Photometric tests and computer analyses of sign illumination levels reduced the number of candidates to ten alternative systems which were then field tested. Each alternative lighting system was tested for 10 to 14 months. Sign luminance was measured with a telephotometer. Power consumption was monitored. Maintenance requirements and lamp life were noted. A human factors study determined legibility distance and rated viewing comfort, lighting uniformity, and color rendition. An economic analysis was performed which considered the initial cost of acquiring and installing the lighting systems and annual costs for electric power, washing, relamping, and ballast replacement. A lighting system using the high pressure sodium light source was recommended. Compared to the existing commonly used fluorescent system, it uses one-third as much electric power and has about one-third of the annual owning and operating cost. The recommended system has a satisfactory illumination level and provides the best legibility distance of the ten systems tested.

The Arizona Department of Transportation (ADOT) completed a comprehensive customer satisfaction assessment in July 2009. ADOT commissioned the assessment to acquire statistically valid data from residents and community leaders to help it identify short-term and long-term transportation priorities. The survey found that state residents feel: Safe on the state's highways; ADOT keeps the roads clean; ADOT keeps the landscaping well maintained; Satisfied with the Motor Vehicle Division; ADOT is moving in the right direction; Dissatisfied with condition of highway shoulders (should be improved); Dissatisfied with nighttime visibility of highway striping; Dissatisfied with the frequency of public transit where they live; and Dissatisfied with traffic flow on highways during rush hour. Both residents and community leaders said the transportation issues with the highest priorities were: Repairing and maintaining existing highways; Enhancing highway safety; and Relieving congestion on highways.
