Available in PDF, EPUB and Kindle. Book excerpt: In countries with severe winters such like Canada, winter road maintenance (WRM) operations, such as plowing, salting and sanding, play an indispensible role in maintaining good road surface conditions and keeping roads safe. WRM is, however, also costly, both monetarily and environmentally. The substantial direct and indirect costs associated with WRM have stimulated significant interest in quantifying the safety and mobility benefits of winter road maintenance, such that systematic cost-benefit assessment can be performed. A number of studies have been initiated in the past decade to identify the links between winter road safety and factors related to weather, road, and maintenance operations. However, most of these studies have focused on the effects of adverse weather on road safety. Limited efforts have been devoted to the problem of quantifying the safety benefits of winter road maintenance under specific road weather conditions. Moreover, the joint effects of and complex interactions between road driving conditions, traffic and maintenance and their impact on traffic safety have rarely been studied. This research aims to determine the effect of WRM on road safety during snow storm events and develop models that can be used to quantify the safety benefit of alternative winter road maintenance policies, strategies and practices.

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 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In countries like Canada, driving conditions can be significantly deteriorated by adverse winter weather conditions, such as ice and snow storms. To reduce the negative effects caused by inclement winter weather conditions, winter road maintenance (WRM) services are implemented by transportation agencies to restore road surfaces to bare conditions and provide safer driving conditions. WRM operations are commonly guided by a set of level of service (LOS) standards that specify the minimum level of service to be achieved for the different classes of highways. Higher highway classes receive higher levels of WRM service. However, WRM activities are costly, incurring both significant monetary costs and negative environmental effects. This research was motivated by the introduction of a new highway class - Urban Freeways (UFW) - in the province of Ontario's highway classification system for winter road maintenance. UFWs include highways with winter average daily traffic volumes greater than 100,000 vehicle/day; they receive the highest WRM level of service. The substantial direct and indirect costs associated with winter road maintenance have stimulated strong interest in quantifying the safety and mobility benefits of upgrading level of service to the new UFW class. This research presents the findings from a field study aimed at comparing the winter road maintenance performance of alternative maintenance standards, and their impacts on safety and mobility. The new UFW class was introduced as a pilot study on four highway sections located in Central and Eastern Ontario, in the 2018-2019 winter season. A statistical analysis of the field test data found that bare pavement regain time was reduced by 40%, while salt usage increased by 139%, after implementing the upgraded winter road maintenance standard. A subsequent analysis was conducted to estimate the expected safety and mobility benefits due to the upgrading of the service standard, providing the critical information needed to make a decision on formal adoption of this new standard in future winter seasons. The analysis results conclude that highways with more severe weather conditions are iv expected to obtain more safety and mobility benefits. Moreover, traffic exposure is the decisive factor of the safety and mobility benefits gained from implementing the new UFW class when highway sections are having similar weather conditions. The monetized safety and mobility benefits, in combination with the additional costs of implementing the Urban Freeway class, could also be used to determine the optimal winter average traffic volume threshold for the Urban Freeway class. While the findings and conclusions of this thesis are only relevant to the study area where the tests were conducted, the underlying methodology can be applied by other jurisdictions that are facing the same problem.

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.

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.

Download or read book Quantifying the Effects of Winter Weather and Road Maintenance on Emissions and Fuel Consumptions written by Jing Min and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Winter road maintenance (WRM) has significant benefits including improving road safety and reducing traffic delay caused by adverse weather conditions. It has also been suggested that WRM is beneficial in terms of reducing vehicular air emissions and fuel consumption because snow and ice on the road surface often cause drivers to reduce their vehicle speeds or to switch to high gears, thus decreasing fuel combustion efficiency of engines. However, there has been very limited information about the underlying relationship, which requires to quantify this particular benefit through a winter road maintenance program. This research is focused on establishing a quantitative relationship between winter road maintenance and vehicular air emissions. Most studies related RSC, fuel consumption and vehicular emission used either lab collected or real-world collected sample data at several specific sites and hours, which usually have small sample sizes. Speed distribution models were developed for the selected highways using data from 22 road sites across the province of Ontario, Canada. Through an intermediate variable - vehicle speed, a quantitative relationship was established between winter road surface condition and vehicular emissions including GHG, harmful gases and PM, and energy consumption. Using multiply linear regression, a speed distribution model, including hourly average speed model and speed variation model, established as a function of various winter weather factors and a measure of road surface condition under the assumption of normal distribution. The vehicular air emissions under different road surface conditions were calculated by coupling the speed models with the engine emission models integrated in the emission estimation model - MOVES. It is found that, on the average, 10% improvement in road surface condition could result in approximately 2% reduction in air emissions. Application of the proposed methodology is demonstrated through a case study to analyse the air emission and energy consumption effects under specific weather events. The results show that better road surface condition (RSC) can reduce both the vehicular air emissions and energy consumption, and the effects of an earlier WRM operation would last longer and affect more during a snow event.
