Available in PDF, EPUB and Kindle. Book excerpt: A new way forward for sustainable quality of life in cities of all sizes Strong Towns: A Bottom-Up Revolution to Build American Prosperity is a book of forward-thinking ideas that breaks with modern wisdom to present a new vision of urban development in the United States. Presenting the foundational ideas of the Strong Towns movement he co-founded, Charles Marohn explains why cities of all sizes continue to struggle to meet their basic needs, and reveals the new paradigm that can solve this longstanding problem. Inside, you’ll learn why inducing growth and development has been the conventional response to urban financial struggles—and why it just doesn’t work. New development and high-risk investing don’t generate enough wealth to support itself, and cities continue to struggle. Read this book to find out how cities large and small can focus on bottom-up investments to minimize risk and maximize their ability to strengthen the community financially and improve citizens’ quality of life. Develop in-depth knowledge of the underlying logic behind the “traditional” search for never-ending urban growth Learn practical solutions for ameliorating financial struggles through low-risk investment and a grassroots focus Gain insights and tools that can stop the vicious cycle of budget shortfalls and unexpected downturns Become a part of the Strong Towns revolution by shifting the focus away from top-down growth toward rebuilding American prosperity Strong Towns acknowledges that there is a problem with the American approach to growth and shows community leaders a new way forward. The Strong Towns response is a revolution in how we assemble the places we live.

Download or read book Using Connected Vehicles in Variable Speed Limit Systems written by Ellen F. Grumert and published by Linköping University Electronic Press. This book was released on 2018-04-10 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: Motorway traffic management systems are useful for improving the traffic conditions on urban motorways. One of the most common motorway traffic management systems are variable speed limit systems. These systems adapt the speed limits based on the prevailing traffic conditions measured by roadside detectors and recommended or compulsory speed limits are shown on variable message signs installed on gantries over the road.Thesystems consist of three parts; the control algorithm used to determine which speed limit to be displayed, a method for estimating the traffic conditions to be used as input for the control algorithm and the infrastructure for application of the variable speed limits. The goal of the systems is often to increase safety or efficiency. Recent development in the field of connected vehicles have opened up for a new type of data source, as the status of a connected vehicle and its surroundings can be communicated at arbitrary locations. Hence, by the use of connected vehicles in variable speed limit systems there is a potential of reducing the amount of roadside equipment. It is even possible to control the connected vehicles towards the current speed limit without the use of variable message signs. This allows for the application of variable speed limits at arbitrary locations. The aim of this thesis is to examine how connected vehicles can be used to improve the efficiency of variable speed limit systems. The thesis contribute with new and improved methods using connected vehicles in all three parts of a variable speed limit system. The suggested methods are evaluated by microscopic traffic simulation. The overall conclusion is that the use of connected vehicles in variable speed limit systems can contribute to improvements in traffic efficiency compared to existing systems. The six papers included in the thesis can be summarized as follows. First, it is shown that traditional variable speed limit systems can be effective for improving the traffic conditions on the motorway and the results can be comparable to more costly alterations by reconstruction of the infrastructure to increase the capacity. Next, the usefulness of connected vehicles for application and control of the speed limits in an existing variable speed limit system is investigated. It is concluded that the design of the control algorithm and the accuracy of the estimated traffic conditions have a great effect on the final outcome of the system. The design of the control algorithm is then examined by evaluation of a number of control algorithms with respect to safety, efficiency and environmental impacts. The main benefits and drawbacks of the algorithms are highlighted and desirable characteristics to include when designing a control algorithm are identified. In two studies, methods making use of connected vehicles for estimating the traffic conditions are proposed. The results show that connected vehicles are useful for improving the accuracy of the estimated traffic conditions through the inclusion of more detailed information and information at locations where detector measurements are not available. Finally, a variable speed limit system is proposed in which connected vehicles play a central role in the estimation of the traffic conditions, as well as in the control algorithm and for application of the speed limit. The system is shown to be useful for improving traffic efficiency during an incident at an arbitrary location along the controlled road.

Download or read book Effects on Speeds of a Rural Variable Speed Limit System written by Emily C. Layton and published by . This book was released on 2011 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Speed limits are generally created for ideal road conditions. When road conditions deteriorate, speed limits tend to become unreasonable, and enforcement of safe driving becomes difficult. Variable speed limit (VSL) systems are used to adjust speeds in accordance with the changing conditions in an attempt to reduce the variation of speeds among all vehicles. This research highlights the findings from the variable speed limit system in place along the Elk Mountain Corridor of I-80 in Southeastern Wyoming during the first and second full winter seasons of VSL implementation. Specifically this research focuses on speeds and variations of speed and the effect the VSL system has had on individual vehicles. The objective of this research was to determine if the VSL system was effective in reducing speeds and speed variation during adverse conditions. Further, this analysis attempts to determine the effect of the VSL system on driver behavior. The VSL system was effective at reducing speeds when properly implemented, reduced speed variation as well. Drivers respond differently to different levels of VSL implementation.

Available in PDF, EPUB and Kindle. Book excerpt: The determination for driver requirements for use in the design of variable speed limit systems was the focus of two human factors studies. Driver preferences and opinions relating to message content, display attributes, operational modes, display location, usage guidelines, and the like were addressed in the first study. This report on the second study deals with the determination of the maximum distance between display components of variable speed systems. The FHWA Highway Simulator (HYSIM) was used to examine driver retention through analysis of the driver's ability to recall speed limit information which changed as a function of distance during a pre-programmed highway scenario. Sixty-three subjects completed the experimental trip. Based on an 85th percentile criterion, a recommendation is made for a maximum distance betwen displays of 5 miles.

Download or read book Variable Speed Limit Decision Support System for the Elk Mountain Corridor Phase 1 written by Jenna Leigh Buddemeyer and published by . This book was released on 2009 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Determining an appropriate speed for the current conditions can be difficult for the driver. Equally difficult is for law enforcement agencies to enforce and cite someone going too fast for conditions. In many cases, drivers are cited for going too fast for conditions only after the accident has occurred. Variable speed limits (VSL) are one type of intelligent transportation system (ITS) that has shown promise for improving safety on roadways subject to adverse conditions. The purpose of this research was to lay the foundation for the new I-80 VSL system in southeastern Wyoming. During this phase of the research, surveys were sent out to all DOTs to see what VSLs have been implemented in the U.S. Driver speed behaviors during both "ideal" and "non-ideal" conditions were found and baseline speeds determined. Weather and speed data were analyzed to determine key variables and threshold values. The final task was to determine how drivers are reacting to the new VSL system. Future work to be done to complete the Decision Support System is also outlined.
