Theory and practice of high-capacity infrastructure projects are the major focus in the development of countries in the Global South. Aiming at a more fine-grained understanding of such projects, Renard Teipelke studies the Thika Highway Improvement Project (THIP) and its outcomes in the peri-urban Northern Nairobi Metropolitan Region. The THIP is a large transportation infrastructure project that expanded the dual carriageway Thika Road into an eight-lane highway from 2008 until 2012. Based on a strategic mix of methodological approaches, such as interviews with experts in Kenya, literature research and field visits, the ‘black box’ THIP is opened up. In the empirical analysis, the project’s idea, its design, and its implementation are studied. It is concluded that the project’s outcomes are ambivalent – partly living up to the expectations of THIP proponents but not resulting in shared benefits for all concerned stakeholders due to flaws in managing the development in this peri-urban transport corridor area, thereby fitting into the Kenyan context of politics and planning.
Various methods of assessing noise, loudness, and noise annoyance are reviewed and explained; sources, types, and intensities of traffic noise are noted; typical means of abatement and attenuation are described; design criteria for various land uses ranging from low-density to industrial are suggested and compared with the results of previous BBN and British systems for predicting annoyance and complaint; and a design guide for predicting traffic noise, capable of being programmed for batch and on-line computer applications, is presented in form suitable for use as a working tool. A flow diagram describes the interrelationships of elements in the traffic noise prediction methodology, and each element is discussed in detail in the text. The text is presented of a tape recording that takes the listener through a series of traffic situations, with such variables as traffic distance, flow velocity, distance, outdoors and indoors, and presence or absence of absorbers and attenuators.
A Brookings Institution Press and Lincoln Institute of Land Policy publication Since the demise of urban renewal in the early 1970s, the politics of large-scale public investment in and around major American cities has received little scholarly attention. In Mega-Projects, Alan Altshuler and David Luberoff analyze the unprecedented wave of large-scale (mega-) public investments that occurred in American cities during the 1950s and 1960s; the social upheavals they triggered, which derailed large numbers of projects during the late 1960s and early 1970s; and the political impulses that have shaped a new generation of urban mega-projects in the decades since. They also appraise the most important consequences of policy shifts over this half-century and draw out common themes from the rich variety of programmatic and project developments that they chronicle. The authors integrate narratives of national as well as state and local policymaking, and of mobilization by (mainly local) project advocates, with a profound examination of how well leading theories of urban politics explain the observed realities. The specific cases they analyze include a wide mix of transportation and downtown revitalization projects, drawn from numerous regions—most notably Boston, Denver, Los Angeles, New York City, Chicago, Atlanta, Dallas, Portland, and Seattle. While their original research focuses on highway, airport, and rail transit programs and projects, they draw as well on the work of others to analyze the politics of public investment in urban renewal, downtown retailing, convention centers, and professional sports facilities. In comparing their findings with leading theories of urban and American politics, Altshuler and Luberoff arrive at some surprising findings about which perform best and also reveal some important gaps in the literature as a whole. In a concluding chapter, they examine the potential effects of new fiscal pressures, business mobilization to relax environmental constraints, and security concerns in the wake of September 11. And they make clear their own views about how best to achieve a balance between developmental, environmental, and democratic values in public investment decisionmaking. Integrating fifty years of urban development history with leading theories of urban and American politics, Mega-Projects provides significant new insights into urban and intergovernmental politics.
This report describes evaluation methods for transport infrastructure investments to ensure that scarce resources are allocated in a way that maximises their net return to society.
