Available in PDF, EPUB and Kindle. Book excerpt: Adverse weather has a direct effect on traffic congestion and the time delay on roads. Weather conditions today are changing rapidly and are more likely to have a severe effect on traffic in the future. Although different measures have been taken to mitigate these conditions, it is important to study the impact of these events on road conditions and traffic flow. For example, the surface of a road is affected by snow, compacted snow and ice. The objective of this thesis is to characterize the effect of road surface conditions on traffic flow. To date, traffic flow under adverse weather conditions has not been characterized. A macroscopic traffic flow model based on the transition velocity distribution is proposed which characterizes traffic behavior during traffic alignment under adverse weather conditions. The model proposed realistically characterizes the traffic flow based on snow, compacted snow, and ice. Results are presented which show that this model provides a more accurate characterization of traffic flow behavior than the well known Payne-Whitham model.

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 2004-03-31 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.

Download or read book Characterization of Vehicle Time Headway in Clear and Rainy Weather written by Atousa Tangestanipour and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Adverse weather has a direct effect on traffic congestion, capacity, and road safety. Rain can influence traffic flow and headway. Thus, it is important to study the impact of weather conditions on traffic. In this thesis, headway data from a north-south highway in Tehran is categorized according to weather conditions and traffic flow. A statistical analysis of this data is presented which show that the mean time headway increases in rainy weather and the traffic flow rate is lower. The probability density functions fit to the headway data and these distributions are then evaluated using the Chi-Squared (C-S) and Kolmogorov- Smirnov (K-S) tests to determine which is the most suitable. To generalize results for different traffic flow rates, another highway was selected for data collection. The results obtained show that the Burr distribution is the best to model the headway data in clear and rainy weather with a higher traffic flow. Moreover, the generalized extreme value distribution is the best to model the headway data in clear and rainy weather with a lower traffic flow. This justifies the use of different time headway distributions in rainy and clear weather conditions and different traffic flow rates for traffic modeling.

Download or read book Integrated Transport written by Moshe Givoni and published by Routledge. This book was released on 2010-07-02 with total page 509 pages. Available in PDF, EPUB and Kindle. Book excerpt: Travel is an essential part of everyday life and today most journeys are multimodal. It is the total travel experience that counts and integrated transport must reduce the inconvenience of transfers between modes. Most research and many publications on transport policy advocate sustainable transport, but the priority given to integration has been negligible. Yet integration is one of the most important means to advance sustainable transport and sustainability more generally. While integrated transport systems are seen to be an ideal, there is a failure to make the transition from policy to practice. The authors argue that the achievement of sustainable transport is still a dream, as an integrated transport policy is a prerequisite for a sustainable transport system. It is only when the two concepts of sustainability and integration operate in the same direction and in a positive way that real progress can be made. In this book, transportation experts from across the world have addressed the questions about what is integration, why is it so important and why is it so hard to achieve? The book provides an in-depth analysis of these issues and it aims to provide a better understanding of the subject, about what should be strived for, about what is realistic to expect, and about how to move forward towards a more integrated provision of transport infrastructure, services and management.
