Book excerpt: This report documents Phase Two, the third full year of a continuing research program by the Arizona Department of Transportation (ADOT) to study vehicle and infrastructure-based Intelligent Transportation Systems technologies. Phase Two of Arizona's Intelligent Vehicle Research Program focused on the critical 2000-2001 winter season. Phase One of the research project was basically a partnership with California to test the Caltrans-PATH advanced snowplow in Arizona. One defining element of Phase Two was the search for a satisfactory new system that could be acquired by ADOT and installed on one of the State's snowplows for long-term testing. The final result of the search, in early 2001, was that the Arizona Transportation Research Center (ATRC) and the Flagstaff District concluded an agreement to purchase one of the 3M Company's Lane Awareness Systems, as well as five miles of 3M tape to guide the vehicle. The second major new factor in Phase Two of this research was the need for formal, unbiased reporting and analysis of the training and evaluation results for the 3M and Caltrans driver-assistance concepts. The ATRC therefore contracted with Northern Arizona University in Flagstaff to monitor the training and testing, to survey stakeholders, to provide evaluation results, and to make recommendations for the future. The ADOT research also was independently supported by the 3M Company, through their own evaluation program contract with the University of Iowa. Despite their prior lack of mountain road snowplow expertise, U-Iowa's driver surveys were of great benefit to ADOT, the ATRC and the NAU evaluation effort. This project faced a number of unexpected setbacks in the Phase Two winter of 2000-2001. Nevertheless, tests and training proceeded at Flagstaff with both systems. The project team developed creative solutions to many obstacles, and pushed ahead. As a result, a great deal was learned from Phase Two, as Arizona developed the first test program in the West with dedicated real-world high-altitude test sites for both the Caltrans and the 3M systems, only 30 miles apart.

Book excerpt: This Phase One report documents a three-year research program by the Arizona Transportation Research Center to study possible practical applications of vehicle and infrastructure-based technologies. The project has reviewed, evaluated and demonstrated Intelligent Vehicle and Automated Highway System concepts that may improve the safety and efficiency of Arizona's highway system, particularly in winter maintenance operations. The key accomplishment of Phase One was to develop a research partnership with the California Department of Transportation (Caltrans) in their Advanced Snowplow (ASP) program. The Caltrans prototype plow, guided by discrete magnetic markers in the roadway, features lane position indication, lane departure warning, and a forward collision warning radar system.

Book excerpt: This report covers Phase Three of a long-term advanced vehicle research program of the Arizona Department of Transportation (ADOT) and its Arizona Transportation Research Center (ATRC). The primary focus of the research has evolved to topics in winter operations. Phase Three, the fifth year of this program, included the 2002-03 winter season. Phase One of this research (1997-2000) began with intelligent-vehicle concept demonstrations relevant to Arizona's specific transportation needs. These early efforts led to a joint program with California to field-test the Caltrans advanced snowplow (ASP) in Arizona conditions. In 1999 and 2000, over two winters, ADOT crews evaluated California's ASP lane-guidance system in four-week test cycles at a three-mile long two-way test loop of embedded roadway magnets near Flagstaff. In Phase Two (2000-01), the key goal was to acquire and test a driver-assistance system for an ADOT snowplow. The project selected the 3M Lane Awareness System, and installed 5 miles of 3M magnetic striping tape at a second test site. The partnership with Caltrans was continued to compare both guidance concepts in similar operating conditions. However, system problems with both research snowplows reduced the ability of ADOT and its partners to evaluate either concept. In Phase Two(b), the 2001-02 winter, ADOT's test and evaluation plans were successful, as the technical issues of the previous winter had been resolved. The key goal of side-by-side plowing operations was hampered by a lack of snowfall during the test period, and the ADOT-3M snowplow's field tests were limited to only a few storms all winter. Overall, both concepts proved their effectiveness and reliability in 2001-02, but the mild weather did not allow the project to document their performance. At this point it was clear to ADOT that the cost of either system was prohibitive, and the research focus for 2002-03 was shifted from roadway-based guidance concepts to commercial on-board warning systems. In the current Phase Three (2002-03), ADOT expanded the research activities to the "I-40 Corridor" districts east and west of Flagstaff. The project equipped seven snowplows with either collision warning radar or passive infrared night vision, at a much more practical level of cost. With these new units in service on seven snowplow routes across northern Arizona, the project determined winter performance results for both of the commercial on-board warning systems. Despite a mild winter, results for the warning radar were positive overall, but ice buildup in storms hampered the night vision system. Both of these systems were judged to be effective and operationally successful, with certain limitations. Their field deployment in northern Arizona will be extended with some refinements for the 2003-04 winter season.

Book excerpt: This report covers Phase Two(b) of a long-term in-house advanced vehicle research program of the Arizona Department of Transportation (ADOT) and its Arizona Transportation Research Center (ATRC). The focus of the research evolved early to winter maintenance topics. Phase Two(b), this fourth year of the program, addresses the 2001-02 winter season. ADOT's Phase One snowplow research (1997-2000) was a joint effort with California to field test the Caltrans advanced snowplow (ASP) in Arizona conditions. ADOT crews evaluated the Caltrans ASP lane-guidance system in four-week test cycles for two consecutive winters at a six-mile test loop of embedded roadway magnets near Flagstaff. ADOT's key goal In Phase Two (2000-01) was to acquire and test its own snowplow driver-assistance system. ADOT procured a 3M Lane Awareness System, with 5 miles of 3M magnetic striping tape to develop a second field site. Testing also continued with Caltrans to compare both lane guidance systems in similar conditions, however, system problems with both concept snowplows severely reduced the ability of ADOT and its partners to effectively evaluate either concept. In this current Phase Two(b), the 2001-02 winter, ADOT's testing and evaluation could proceed as the system problems of the previous winter had been resolved. The goals were based on same-day training for ADOT drivers with both advanced snowplow systems. However, the side-by-side operational testing of the Caltrans and 3M systems was limited by a total lack of snowfall in the Flagstaff area during the five weeks that the Caltrans RoadView plow was in Arizona. The Caltrans RoadView team did conduct night testing with ADOT drivers so that their performance could be monitored and evaluated ADOT's own evaluation effort experienced only a few major storms all winter; and the ADOT-3M plow operated effectively in these storms. Overall, both systems showed their effectiveness and reliability in 2001-02, but the weather provided few opportunities to document the key advantages for either system. By this point in the program, after four winters of field tests, it had also become clear to the project sponsors that the current cost of either system was prohibitive for Arizona. As a result, it was decided to shift the future research focus in 2002-03 (Phase Three) from roadway-based guidance systems to commercial on-board driver-warning systems.

Book excerpt: This report presents the methodology and results of a study to develop a strategic plan to deploy Intelligent Transportation Systems(ITS) throughout rural Arizona. Needs were identified by various stakeholders at Rural ITS Workshops, focus group meetings, and regional Coalition meetings around the state. These needs were then matched, where possible, to one or more of the 36 Federal Highway Administration (FHWA) User Services defined in the National Program Plan and Advanced Rural Transportation Systems (ARTS) program. Using the National ITS Architecture as a guide, a conceptual system architecture was developed for Arizona, which includes integration with other architectures developed for previous strategic plans in the state.
