Book Synopsis Strong Towns by : Charles L. Marohn, Jr.
Download or read book Strong Towns written by Charles L. Marohn, Jr. and published by John Wiley & Sons. This book was released on 2019-10-01 with total page 262 pages. 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.

Book Synopsis Stateless Commerce by : Barak Richman
Download or read book Stateless Commerce written by Barak Richman and published by Harvard University Press. This book was released on 2017-06-19 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Stateless Commerce, Barak Richman uses the colorful case study of the diamond industry to explore how ethnic trading networks operate and why they persist in the twenty-first century. How, for example, does the 47th Street diamond district in midtown Manhattan—surrounded by skyscrapers and sophisticated financial institutions—continue to thrive as an ethnic marketplace that operates like a traditional bazaar? Conventional models of economic and technological progress suggest that such primitive commercial networks would be displaced by new trading paradigms, yet in the heart of New York City the old world persists. Richman’s explanation is deceptively simple. Far from being an anachronism, 47th Street’s ethnic enclave is an adaptive response to the unique pressures of the diamond industry. Ethnic trading networks survive because they better fulfill many functions usually performed by state institutions. While the modern world rests heavily on lawyers, courts, and state coercion, ethnic merchants regularly sell goods and services by relying solely on familiarity, trust, and community enforcement—what economists call “relational exchange.” These commercial networks insulate themselves from the outside world because the outside world cannot provide those assurances. Extending the framework of transactional cost and organizational economics, Stateless Commerce draws on rare insider interviews to explain why personal exchange succeeds, even as most global trade succumbs to the forces of modernization, and what it reveals about the limitations of the modern state in governing the economy.

Book Synopsis Comparison of Single Point Urban Interchange and Diverging Diamond Interchange Through Simulation by : Rawan Ramadhan
Download or read book Comparison of Single Point Urban Interchange and Diverging Diamond Interchange Through Simulation written by Rawan Ramadhan and published by . This book was released on 2019 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1960, there were 74,431,800 vehicles registered in the United States. Looking at the most recent data currently available shows that in 2016 there were 268,799,083 registered vehicles in the United States. Roadway facilities constructed in the 1960s were not designed to handle vehicular traffic of these proportions. The ever increasing volumes of motor vehicle traffic at heavily traveled interchanges and intersections heighten the risk of single or multiple vehicle crashes particularly when they are not designed to manage high volumes. Traffic engineers from state and federal departments of transportation have responded to calls for safer roads and interchanges in some areas that have been identified as dangerous because of an increase in fatal and non-fatal motor vehicle crashes. In the road network the highway system and the local street system are related. According to the Federal Highway Administration, "the term interchange means the junction of two or more streets requiring partial or complete grade separation." Interchanges located in urban areas are utilized to facilitate traffic flow between arterial roadways and freeways on- and off-ramps. Congestion and safety are the two main objectives traffic engineers consider while remodeling an interchange design. Several types of renovated interchanges are normally considered to meet the growing population mobility needs. The Single Point Urban Interchange (SPUI) is one of the solutions has been considered since 1974 but it was flourished and implemented in the 1990s. The other innovative interchange solution appeared first in France in the mid-1970s known as Diverging Diamond Interchange (DDI). Likewise, the DDIs did not gain popularity back then until in the 2000s. The first DDI in the United States was constructed in 2009 in Springfield, Missouri.The main aim of this study is to compare the performance of traffic flow between SPUI and DDI based on existing traffic data for a peak hour retrofitting an existing Conventional Diamond Interchange (CDI). The analysis of the two interchange designs in conjunction with the existing design are used in the comparison study to identify which interchange design performs best among each other. The Measures of Effectiveness (MOEs) used in this study include queue delay, queue length, vehicle delay and stopped delay. This study obtain traffic turning movements and signal timing data from the Ohio Department of Transportation (ODOT). The turning movement counts (TMC) were taken from ODOT's Transportation Data Management System for the year 2017. VISSIM version 11 software was used for microscopic simulation. The optimum signal phasing for the three interchange designs were obtained from SYNCHRO 10 software based on the PM peak hour traffic data. The virtual interchange network design geometry in both software programs were almost identical. Several assumptions were made to stay consistent as much as possible while comparing the three designs since they have completely different geometric layouts. For example, the existing CDI data included the through movements from off-ramps to on-ramps. Since the two alternative designs (SPUI and DDI) exclude the through movements from off-ramps to on-ramps, their data were added to the right turn movements. Moreover, the speed limit was set to be in the range of 30 mph while driving in the interchange to meet all three design specifications.The analysis of results show that there are significant advantages and disadvantages associated with each design (CDI, SPUI and DDI). During implementation, various factors such as cost, efficiency, safety, delay, etc., need to be considered when attempting to select the best design, which would be the most appropriate method as these may vary from situation to situation. However, in the current study, a DDI performed best, followed by a SPUI, and then CDI was last. Moreover, CDI with its signal timing optimized very highly improved all MOEs considered when compared with the CDI with existing signal timing.
