Book excerpt: The last few years have witnessed a leap forward by road maintenance agencies, with the adoption of new equipment, materials, and new application techniques, such as liquid anti-icing and pre-wetting. The development and proliferation of Road Weather Information Systems (RWIS) are positive steps into the direction of more advanced winter maintenance operations. While Road Weather Information Systems are gaining acceptance and popularity, they are only tools in a tool box and they do not become useful unless they are part of an interconnected system for the operation and management of the road winter maintenance operation. This paper will discuss how RWIS does not work independently, and must be integrated with other systems and tools to provide proper methodologies of decision-making. The paper will also touch on what requirements that must be met before adopting a road weather information system in a decision making process.

This book was released on 2020 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: A transportation agency’s ability to deliver effective winter road maintenance combines three essentials: a professional, knowledgeable staff, including trained snowplow operators; a fleet of high quality, well-maintained equipment and appropriate supplies; and, perhaps most important and most difficult to consistently acquire, accurate and timely weather information. Sources of weather information for transportation agencies are many and varied. This synthesis project sought to determine the best practices agencies use to acquire accurate and timely weather information to strategize and deploy equipment for winter road maintenance operations. The project also examined the practices used to convey information about forecasts and road weather conditions between agency offices and operators in the field. Two surveys directed to winter road maintenance practitioners at Clear Roads member agencies gathered information from central office staff and field personnel. Results of a literature search supplement survey findings.

Available in PDF, EPUB and Kindle. Book excerpt: Weather has broad and significant effects on the roadway environment. Snow, rain, fog, ice, freezing rain, and other weather conditions can impair the ability of drivers to operate their vehicles safely, significantly reduce roadway capacity, and dramatically increase travel times. Multiple roadway activities, from roadway maintenance and construction to shipping, transit, and police operations, are directly affected by inclement weather. Some road weather information is available to users currently, however a disconnect remains between current research and operations, and additional research could yield important safety and economic improvements for roadway users. Meteorology, roadway technology, and vehicle systems have evolved to the point where users could be provided with better road weather information through modern information technologies. The combination of these technologies has the potential to significantly increase the efficiency of roadway operations, road capacity, and road safety. Where the Weather Meets the Road provides a roadmap for moving these concepts to reality.

This book was released on 2006 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: The major objective of the study was to develop a procedure to determine the level of service using the RWIS speed measurements. The procedure developed can be used by ODOT to evaluate winter maintenance activities and for winter maintenance decision making. Average traffic speeds for five minute intervals were measured using NuMetrics road sensors and they were related to the pavement and driving conditions. In addition speed data from two other studies was used. The pavement conditions were determined by conducting surveys at rest area buildings using a questionnaire form. It was found that the average traffic speeds were significantly lower during a major snow event even when periodic plowing and salting was done. The average speeds decreased almost linearly for the period of the snow storm reached the minimum and then climbed back slowly towards higher speeds. The speeds appear to be a fairly sensitive measure to judge the condition of the pavement. The motorist judgments about the pavement condition and their perception of the safety of driving decreases during a rather severe winter storm which is mirrored in the speed decrease. It appears from the survey that about two thirds of the motorists judge the deterioration of the road conditions and the inadequate level of road maintenance during a winter storm as bad or moderately bad. The responses obtained for the car and the truck drivers are fairly close to each other indicating that both groups can judge bad road condition equally well. The observed road conditions appear to influence the drivers in terms of how they subjectively feel about the level of safety and stress experienced during driving in the winter storm. A simple procedure was developed for winter maintenance management to determine the condition of the road (freeways) based on the average speeds observed by the RWIS sensors. If the average winter speed of the traffic is equal or greater than the historical established wet/salted pavement speed, the level of service is considered adequate. According to the Swiss study, the wet/salted surface winter speeds are about 85% of the dry surface speeds for freeways and 96 % for city streets. If the average winter speed is below the wet/salted surface speed, the level of service is considered inadequate. Any speed less than 50% of the wet/salted surface speed indicates fairly bad road conditions and an extremely inadequate level of service. It should be noted that the winter pavement conditions can be highly dynamic. Depending on the rate of accumulation of snow, frequency of the snow plowing, length of the snow plow route, the pavement condition can improve and deteriorate a number of times during a winter storm. The level of service can get worse even with maximum snow plowing and salting effort in a situation with a high rate of snow accumulation. The winter speeds observed as a percentage of the average dry surface speed can be correlated with the level of service. A relatively more fine graduation of the level of service as a function of the percentage of the average dry surface speed is proposed in the recommendations of the report.

This book was released on 2020 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: Author's abstract:Managing winter roadway treatment can be a challenge where winter is not severe, but snowfall is experienced a few times a year. Winter weather makes the road dangerous and challenging to travel. Most US states have approached and implemented different winter road maintenance practices to make transportation of goods, services, and people uninterrupted. However, the state of Georgia has always struggled to deal with winter weather. Recently, there has been some progress. The Georgia Department of Transportation prepared a winter road treatment plan in 2019, and they are still working on improving it. Increasing emphasis on pre-treating the road rather than relying heavily on snow plowing and other post-treatment is the current trend in winter road maintenance. Pre-treatment reduces chemical use and has several other benefits. In this research, a pre-treatment requirement model was developed to calculate the amount of brine required to melt different snow and ice amounts. In the last three years, Georgia faced a few snow events; three were selected for analysis using the developed model. The study revealed that adjusting the pre-treatment amount at smaller snow events can eliminate the need for post-treatment. The model suggests that different parts of a route require different amounts of pre-treatment. The application of the brine amount can be adjusted based on snow accumulation prediction by the model. The model sensitivity analysis showed that more snow is accumulated at lower temperatures, and the effectiveness of brine in melting snow diminishes. Higher wind speed increases snowmelt resulting in lowered brine application requirements. The decision-making tool can optimize the amount of brine used by suggesting location and pre-treatment amount. The output of the model can be used in better decision making on winter road pre-treatment.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Effective and efficient removal of snow and ice from public roadways is a key outcome for winter road maintenance operations. This outcome depends on the severity of the wintry weather as well as the quality and quantity of resources used to treat the roadways. A winter weather severity index has been developed that can be used to evaluate the performance of winter weather maintenance. This project involves the development of a physically-based analysis of winter severity, using estimates of the hourly rate of deposition of new snow/ice and the energy required melt it. The "Road Weather Severity Based on Environmental Energy" (RWSBEE) index can be considered an accumulation of energy, beyond that which is available from the environment, needed to melt snow/ice that has been deposited on the road surface on an hourly basis. The energy not provided by the environment that would be required to melt new snow can be thought of as a measure of the work required to remove the new snow from the road surface. We expect RWSBEE to provide a clearer understanding of the severity of the weather, allowing INDOT to better evaluate their performance, assist with after-action review of recent storms, and improve the reaction to future weather events.Winter weather conditions that occur across different regions vary substantially from hour-to-hour, storm-to-storm, and season-to-season. The methods of road maintenance for fighting snow and ice can also vary between different maintenance units. It is important for organizations that perform road maintenance to be able to quantify the severity of the winter weather conditions, for purposes of monitoring, planning, and evaluating their performance. The Indiana Department of Transportation (INDOT) currently uses estimates of winter weather hours to quantify the severity of winter weather. INDOT has determined that the information provided by the weather hour estimates result in wide variations in roadway treatment expenses across Indiana. State-of-the-art weather information can provide a clearer understanding of the severity of the weather, allowing INDOT to better evaluate their performance, assist with after-action review of recent storms, and improve the reaction to future weather events.

Available in PDF, EPUB and Kindle. Book excerpt: Although today's maintenance managers have a variety of good information which can lead to effective snow and ice control, all of the regulations concerning chemical applications, environmental impacts and multiple, often contradictory, weather and road weather forecasts can lead to information overload for the field operations decision maker. The Federal Highway Administration (FHWA) since 1999 has been developing and field testing a Maintenance Decision Support System (MDSS) for snow and ice control operations. The MDSS project integrates state-of-the-art weather and road weather forecasting, data fusion, and optimization techniques with computerized snow and ice control rules of practice logic. This paper will provide an overview of the prototype MDSS system, its successes and lessons learned in snow and ice control operations in the Midwestern United States and the 2004-2005 field tests in the more complex weather regions of Colorado. Annual maintenance savings (materials, equipment and labor) will also be discussed. For the covering abstract of this conference see ITRD number E211426.

Available in PDF, EPUB and Kindle. Book excerpt: This purpose of this research project is to provide a current benefit-cost assessment for weather information in winter road maintenance. To this end, the research team first summarized the weather information resources used by transportation agency personnel in making winter maintenance decisions and investigated how weather information was used to support winter maintenance operations, through extensive literature reviews and surveys to winter maintenance professionals and the meteorological community. Following this, the research team developed a model for winter maintenance costs. A methodology of artificial neural network and sensitivity analysis was proposed and applied to three case studies to analyze the benefits and costs associated with the use of weather information. The benefit cost analysis showed that the use of weather information could bring more benefits than costs. Moreover, it was found that winter maintenance costs could be reduced by improving the accuracy of weather information and/or increasing the use of weather information. Finally, this study identified secondary benefits of deploying and using road weather information systems. These research results should help transportation agencies to guide and direct future investment in weather information services and technologies.
