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.

Available in PDF, EPUB and Kindle. Book excerpt: The Handbook of Intelligent Vehicles provides a complete coverage of the fundamentals, new technologies, and sub-areas essential to the development of intelligent vehicles; it also includes advances made to date, challenges, and future trends. Significant strides in the field have been made to date; however, so far there has been no single book or volume which captures these advances in a comprehensive format, addressing all essential components and subspecialties of intelligent vehicles, as this book does. Since the intended users are engineering practitioners, as well as researchers and graduate students, the book chapters do not only cover fundamentals, methods, and algorithms but also include how software/hardware are implemented, and demonstrate the advances along with their present challenges. Research at both component and systems levels are required to advance the functionality of intelligent vehicles. This volume covers both of these aspects in addition to the fundamentals listed above.

Available in PDF, EPUB and Kindle. Book excerpt: The Arizona Department of Transportation's (ADOT's) SPR-570: Rural ITS Progress Study - Arizona 2004 provided 20 key recommendations for improved utilization of the rural Intelligent Transportation Systems (ITS) infrastructure. Two years later, in reviewing the outcomes of the 2004 study and the ongoing rural technology deployments, the Department identified several of the key concerns as still being unresolved. In general, ADOT has been successful in implementing the recommendations of the 2004 statewide review, but five areas of unmet needs or unfulfilled potential remain. These five gap areas are the primary focus of this new research project, to fully implement the potential of all of the recommendations from the 2004 study. The five primary focus areas are: ITS maintenance, weather information systems, highway advisory radio, motorist assist patrols, and information sharing. The research team interviewed the project's stakeholders from Arizona's rural districts to identify recent changes in their ITS deployment, goals, and visions for future deployment, as well as current needs and desires since the previous 2004 study. The investigators also reviewed the current practices and concepts of rural ITS among other transportation agencies throughout the country. This included conducting personal interviews with recognized industry leaders, attending industry conferences, and performing extensive research in literature, products (both off-the-shelf and in-development), and on-line. Based on the interviews and state-of-the-practice research components, the investigators developed a list of ITS concepts that might service the rural needs of the Department. Each of the five focus areas contains several concepts that address needs identified as original project goals, or new topics identified during the field interviews. Each discussion section provides a conceptual approach and application of ITS technology or state-of-the-practice development, a breakdown of benefits and challenges for implementation, implementation recommendations and a breakdown of the engineer's opinion of cost. Each concept has been ranked by the project advisory group based on implementation priority. A potential process owner and potential resources for deployment are also identified.
