Download or read book Performance Measures for Snow and Ice Control Operations written by T. H. Maze and published by . This book was released on 2007 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Under the NCHRP 06-17 project, the research team surveyed snow and ice control organizations in the United States, Canada, Europe, and Asia to determine the current trends in performance measurement. The team also inquired about the methods used in developing these programs in order to determine a practical, user friendly method to assist snow and ice control managers in developing a performance measurement system that uses traditional and nontraditional performance indicators and measurement issues. To achieve the project objectives, the researchers issued a survey to snow and ice control agencies throughout North America, Europe, and Asia to obtain data of the performance indicators and measures used, if any, by these agencies. The identified performance indicators and measures were then categorized, defined, and assessed for their usefulness. A process was then developed to assist snow and ice control operations managers in preparing a customer-focused, environmentally friendly performance measurement program.

Book excerpt: Weather can have a profound, negative impact on mobility and traveler safety. Nationally, adverse weather is a factor in 1.5 million car and truck crashes and costs society nearly $42 billion annually. Through intelligent transportation systems (ITS) and better road weather information, winter maintenance managers, traffic managers, and travelers now have the opportunity to manage traffic and travel to more effectively ameliorate weather's safety and productivity challenges. In the past few years, weather-related transportation issues have become a priority for the national research agenda. On June 14, 2004, the Iowa Department of Transportation hosted a regional, multi-disciplined forum. The purpose of the forum was to identify Midwest regional research and technology transfer priorities in weather-related transportation research and to discuss the possibility of establishing a regional research program to support the national road weather research agenda. The June 14 Weather Issues in Transportation focus group forum provided an opportunity for transportation agency professionals, professionals representing transportation users, commercial weather data and forecast providers, and members of the meteorology community to express their priorities for weather-related transportation research and technology transfer. Focus groups were organized into the following eight initiatives: (1) Weather Providers, (2) Weather Users, (3) Maintenance Equipment & Technologies, (4) Maintenance Management, (5) Maintenance Operations, (6) Traffic Operations & Safety, (7) Intermodal Traffic, and (8) Design & Construction. The focus groups identified and ranked 25 research problem statements that would require over $20 million for first-year funding if all projects were started in the same year.
Book Synopsis Performance Measurement for Highway Winter Maintenance Operations by : Lin Qiu
Download or read book Performance Measurement for Highway Winter Maintenance Operations written by Lin Qiu and published by . This book was released on 2009 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this research project was to develop a method to measure the performance of a winter maintenance program with respect to the task of providing safety and mobility to the traveling public. Developing these measures required a number of steps, each of which was accomplished. First, the impact of winter weather on safety (crash rates) and mobility (average vehicle speeds) were measured by a combination of literature reviews and analysis of Iowa Department of Transportation traffic and Road Weather Information System data. Second, because not all winter storms are the same in their effects on safety and mobility, a method had to be developed to determine how much the various factors that describe a winter storm actually change safety and mobility. As part of this effort a storm severity index was developed, which ranks each winter storm on a scale between 0 (a very benign storm) and I (the worst imaginable storm). Additionally a number of methods of modeling the relationships between weather, winter maintenance actions and road surface conditions were developed and tested. The end result of this study was a performance measure based on average vehicle speed. For a given class of road, a maximum expected average speed reduction has been identified. For a given storm, this maximum expected average speed reduction is modified by the storm severity index to give a target average speed reduction. Thus, if for a given road the maximum expected average speed reduction is 20 mph, and the storm severity for a particular storm is 0.6, then the target average speed reduction for that road in that storm is 0.6 x 20 mph or 12 mph. If the average speed on that road during and after the storm is only 12 mph or less than the average speed on that road in good weather conditions, then the winter maintenance performance goal has been met.

Available in PDF, EPUB and Kindle. Book excerpt: Real-time measurement of tire-road friction coefficient is extremely valuable for winter road maintenance operations and can be used to optimize the kind and quantity of the deicing and anti-icing chemicals applied to the roadway. In this project, a wheel based tire-road friction coefficient measurement system is first developed for snowplows. Unlike a traditional Norse meter, this system is based on measurement of lateral tire forces, has minimal moving parts and does not use any actuators. Hence, it is reliable and inexpensive. A key challenge is quickly detecting changes in estimated tire-road friction coefficient while rejecting the high levels of noise in measured force signals. Novel filtering and signal processing algorithms are developed to address this challenge including a biased quadratic mean filter and an accelerometer based vibration removal filter. Detailed experimental results are presented on the performance of the friction estimation system on different types of road surfaces. Experimental results show that the biased quadratic mean filter works very effectively to eliminate the influence of noise and quickly estimate changes in friction coefficient. Further, the use of accelerometers and an intelligent algorithm enables elimination of the influence of driver steering maneuvers, thus providing a robust friction measurement system. In the second part of the project, the developed friction measurement system is used for automated control of the chemical applicator on the snowplow. An electronic interface is established with the Force America applicator to enable real-time control. A feedback control system that utilizes the developed friction measurement sensor and a pavement temperature sensor is developed and implemented on the snowplow.
Book Synopsis Evaluation of Different Winter Road Conditions and Effectiveness of Winter Road Maintenance Operations by : Sahar Salimi
Download or read book Evaluation of Different Winter Road Conditions and Effectiveness of Winter Road Maintenance Operations written by Sahar Salimi and published by . This book was released on 2014 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study uses friction measurements of Real Time Traction Tool (RT3)-Curve to characterize different road conditions, evaluate the effect of winter maintenance operations, and identify influential parameters. The reliability of RT3-Curve device was verified by a speed-dependency analysis. Evaluation of different road conditions showed that ice and snow reduced the dry surface friction considerably and friction decreased as more snow was accumulated. More traffic passes cause ice and moderate-to-heavy snow to become more slippery, while it causes higher friction over light snow. Analysis of winter maintenance operations showed that plowing may not be beneficial for ice, but it is the critical operation for snow. Low sanding did not necessarily improve friction; however, medium and high sanding considerably increased friction over ice and snow. A regression analysis revealed that sand/salt quickly scatters off dry and icy roads due to high-speed traffic; however, salt was immediately effective for snow.
Download or read book Gravel Roads written by Ken Skorseth and published by . This book was released on 2000 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.
