Traffic and expenditures on Arizona state highways by Eric Matranga( Book )

4 editions published in 2000 in English and held by 24 WorldCat member libraries worldwide

Using Arizona Department of Transportation data, this study examines the distribution of expenditures, revenues and vehicle utilization of Arizona's state highways from 1986-1998. Three measures are used to evaluate the distribution of highway infrastructure spent over this period: 1) the ratio of revenue generated per vehicle mile; 2) the ratio of the number of vehicle miles generated per expenditure dollar; and 3) the revenue dollars generated per expenditure dollar
Evaluation of measures to minimize wildlife-vehicle collisions and maintain wildlife permeability across highways : Arizona Route 260( Book )

2 editions published in 2007 in English and held by 21 WorldCat member libraries worldwide

The authors conducted wildlife-highway relationships research from 2002-2006 along a 17-mile stretch of State Route 260 in Arizona which is being reconstructed in five phases with 11 wildlife underpasses and six bridges. Reconstruction phasing allowed the authors to use a before-after-control experimental approach in their research. The objectives of their research were: 1) assess and compare wildlife use of underpasses; 2) evaluate highway permeability and wildlife movements among reconstruction classes; 3) characterize wildife-vehicle collision patterns and changes with reconstruction; 4) assess relationships among highway traffic volume and wildlife vehicle collisions, elk crossing patterns, and wildlife use of underpasses; 5) assess the role that ungulate-proof fencing plays in wildlife vehicle collisions, wildlife use of underpasses, and wildlife permeability; 6) provide ongoing highway reconstruction implementation guidance. The authors used video surveillance to assess and compare wildlife use of five underpasses at which they recorded 8,455 animals and 11 different species; 5,560 of these animals (65.8%) crossed through the underpass. The authors employed global positioning system telemetry to assess highway permeability across SR 260, with 65 elk fitted with receiver collars. Elk crossed State Route 260 5,749 times. Elk permeability on reconstructed highway (0.43 crossings/approach) was half that of control sections. Permeability increased 60% after ungulate-proof fencing was erected on a reconstructed section. Effective monitoring and adaptive management yielded benefits to highway safety and wildlife permeability alike
Arizona Intelligent Vehicle Research Program : phase two : 2000-2001 by Stephen R Owen( Book )

4 editions published in 2002 in English and held by 21 WorldCat member libraries worldwide

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
The cost effectiveness and magnitude of potential impact of various congestion management measures by Matthew Rowell( Book )

4 editions published in 1997 in English and held by 21 WorldCat member libraries worldwide

Phoenix and Tucson are "non-attainment" areas under the Environmental Protection Agency's air quality guidelines. Vehicle traffic is the main man-made source of the region's air quality problems. Various methods for reducing the vehicular contribution to air pollution are constantly under consideration and debate. The potential impact on air quality of each measure varies. Each measure also has a different price associated with it. The purpose of this report is to provide policy makers with a guide to options that are available to reduce congestion that may lead to a more cost-effective program for reducing vehicle generated air pollution

Arizona Intelligent Vehicle Research Program : phase one : 1997-2000 by Stephen R Owen( Book )

3 editions published in 2001 in English and held by 19 WorldCat member libraries worldwide

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

Arizona Intelligent Vehicle Research Program : phase three, 2002-2003 by Stephen R Owen( Book )

2 editions published in 2004 in English and held by 18 WorldCat member libraries worldwide

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

Performance evaluation of Portland cement concrete pavement joint sealants by Sylvester A Kalevela( Book )

1 edition published in 1994 in English and held by 16 WorldCat member libraries worldwide

In July 1986, the Arizona Transportation Research Center (ATRC) coordinated the installation of a joint sealant test site near Flagstaff, between mile posts 331.5 and 332.2, on the southbound lanes of Interstate 17. The original project was constructed in 1974, with 8 in. (20 cm) of portland cement concrete pavement (PCCP) over 6 in. (15 cm) of cement treated base (CTB). The test site consisted of 200 transverse joints sawed 2 in. (5 cm) deep, skewed 1:6, and spaced at a repeating sequence of 17, 15, 13, and 15 ft (5.2, 4.6, 4.0, and 4.6 m). The objective of the project was to evaluate the performance of five joint sealants: Dow Corning 888, Superseal 888, Allied Koch 9005, Crafco Roadsaver 231, and W.R. Meadows Sof-Seal. The highway sections abutting this test site were also rehabilitated and their pavement joints were sealed with Superseal 444 which, at that time, was a specified sealant in the Arizona Department of Transportation (ADOT) standards. Field evaluations of the joint sealants were performed at nine months, one year, 1.5 years, 3 years, and 8 years after construction. The evaluations were based on: (i) sealant flexibility, (ii) length of joint with missing sealant, (iii) adhesive and cohesive failure of sealant, (iv) joint width and sealant depth, (v) joint spalling, (vi) sealant recess, (vii) Falling Weight Deflectometer testing, and (viii) slab faulting. Generally, it appeared that after about eight years of service all five sealants had exhibited comparable performance level. Clearly, all test sealants performed better than Superseal 444 which was an ADOT specified joint sealant when the test site was installed in 1986
Expert project recommendation procedure for ADOT's pavement management system by Gerardo W Flintsch( Book )

3 editions published in 1997 in English and held by 16 WorldCat member libraries worldwide

The Arizona Department of Transportation, ADOT, uses a network level pavement management system to determine budget requirements for their annual pavement preservation program. While this is a valuable tool for preservation programming, it does not assist the engineers with the selection of projects and rehabilitation treatments. The research documented in this paper was designed to enhance the capability of ADOT's pavement management system to include project selection
Arizona Intelligent Vehicle Research Program : Phase Two(b): 2001-2002 by Stephen R Owen( Book )

3 editions published in 2003 in English and held by 16 WorldCat member libraries worldwide

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
Porous pavement for control of highway run-off by Mustaque Hossain( Book )

4 editions published in 1991 in English and held by 15 WorldCat member libraries worldwide

In 1986, the Arizona Department of Transportation (ADOT) constructed a 3500- foot porous pavement experimental section on SR-87 in the Phoenix metropolitan area. The objectives of this project were to determine the constructibility and subsequent performance of porous pavement as a drainage system and pavement structure in an urban area and a desert environment. The porous pavement test section has performed satisfactorily for five years. Although a slight decrease in the infiltration rate has occurred, both the infiltration rate and the storage capacity are above the design values. Visual observation during storm events has shown that the surface of the porous pavement section does not include sheet flow. This provides a marked difference in stripe delineation and pavement glare during night time inclement weather driving when compared to conventional pavement. However, Mu-meter meter skid test results for the porous pavement section are comparable to those of conventional pavements (control). Material tests conducted on the pavement components indicate that the Marshall stability, resilient modulus, and asphalt cement viscosity of the open graded asphalt concrete have increased with time. No cracking or significant surface deformation has occurred during the five years of service. Annual FWD testing was conducted to establish the changes in layer properties. To date, little change has occurred in the layer moduli except for the open graded subbase whose modulus has decreased with time. This phenomenon is unexplained at present. No unusual presence of moisture was detected in any layer of the pavement system. The subgrade moisture content has achieved equilibrium at less than the optimum content determined during the design process

Paving fabrics for reducing reflective cracking by Mushtaqur Rahman( Book )

3 editions published in 1989 in English and held by 12 WorldCat member libraries worldwide

This report documents the installation of three commercially available paving fabrics for the reduction of reflective cracking in asphalt overlays. The fabrics installed were Paveprep, Glassgrid, and Tapecoat. The test section is in Willcox, Arizona, on State Route 186. The Willcox rehabilitation project, RS-274-(8)P, involved milling and replacing 2 in. of asphalt concrete, and placing pavement reinforcing fabric. A total of 600 linear feet of each product was placed over transverse cracks, and an additional 100 to 300 ft of each product were placed over random cracks. Markers were placed on the curbs to help monitor the performance of the fabrics during the next 3 years. Problems which occurred during installation of the fabrics are described

The history, development, and performance of asphalt rubber at ADOT : special report by Larry Scofield( Book )

3 editions published in 1989 in English and held by 10 WorldCat member libraries worldwide

This report evaluates ADOT's two decades of experience with asphalt-rubber materials. It discusses the chronological development of asphalt rubber by ADOT and the five principle uses of asphalt rubber. The performance of asphalt-rubber materials are determined from historical records and pavement test sections. The performance of asphalt rubber is evaluated by utilizing historical data from ADOT's pavement management system database and by reviewing eight experimental projects which included 47 test sections. Pavement condition distress surveys were performed on several of these projects to determine the terminal condition of the pavements. Asphalt-rubber materials have been placed on over 700 miles of roadway on the State system
