Download or read book Where the Weather Meets the Road written by National Research Council and published by National Academies Press. This book was released on 2004-05-01 with total page 189 pages. 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.

Book Synopsis Collaborative Research on Road Weather Observations and Predictions by Universities, State DOTs and National Weather Service Forecast Offices by : Victoria Johnson
Download or read book Collaborative Research on Road Weather Observations and Predictions by Universities, State DOTs and National Weather Service Forecast Offices written by Victoria Johnson and published by . This book was released on 2004 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Federal Highway Administration (FHWA) Road Weather Management program partnered with the National Weather Service (NWS) to sponsor five research projects through the Cooperative Program for Operational Meterology, Education, and Training (COMET). The goal was to create teams of personel from State departments of transportation (DOT), NWS Weather Forecast Offices (WFO), and universities to foster collaborative and productive relationships between meterological and transportation agencies. These teams were to use data from Road Weather Information Systems (RWIS) to improve the utilization of these data in both weather and transportation operations and to create new predictive algorithms for use in road maintenance activities. Such advances in road weather management ultimately will improve mobility on the roads, and DOT productively in operations.

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.
Book Synopsis Evaluation of ODOT Roadway/weather Sensor Systems for Snow & Ice Removal Operations by : Helmut T. Zwahlen
Download or read book Evaluation of ODOT Roadway/weather Sensor Systems for Snow & Ice Removal Operations written by Helmut T. Zwahlen and published by . 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.

Download or read book Beyond Road Weather Information as a Decision-making Tool in Winter Maintenance Operations - what Else is Needed? written by and published by . This book was released on 2005 with total page 6 pages. Available in PDF, EPUB and Kindle. 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. For the covering abstract of this conference see ITRD number E211426.
