How Effective are Toll Roads in Improving Operational Performance?

The main focus of this research is to develop a systematic analytical framework and evaluate the effect of a toll road on region’s traffic using travel time and travel time reliability measures. The travel time data for the Triangle Expressway in Raleigh, North Carolina, United States was employed for the assessment process. The spatial and temporal variations in the travel time distributions on the toll road, parallel alternate route, and near-vicinity cross-streets were analyzed using various travel time reliability measures. The results indicate that the Triangle Expressway showed a positive trend in reliability over the years of its operation. The parallel route reliability decreased significantly during the analysis period, whereas the travel time reliability of cross-streets showed a consistent trend. The stabilization of travel time distributions and the reliability measures over different years of toll road operation are good indicators, suggesting that further reduction in performance measures may not be seen on the near vicinity corridors. The findings from link-level and corridor-level analysis may help with transportation system management, assessing the influence of travel demand patterns, and evaluating the effect of planned implementation of similar projects

Contextualising empowerment practice: negotiating the path to becoming using participatory video processes

Participation and empowerment are major drivers of social policy, but participatory projects often happen within contested territory. This research interrogates the assumed participation-empowerment link through the example of participatory video. Fieldwork unpacks the particular approach of Real Time, an established UK project provider. Disrupting representational framing, the emergent relational processes catalysed were explored in context, to address not whether participatory video can increase participants’ influence, but how and in what circumstances. This thesis therefore builds more nuanced understanding of empowerment practice as the negotiated (rhizomic) pathway between social possibility and limitation. Following Deleuze, a becoming ontology underpinned study of project actors’ experiences of the evolving group processes that occurred. An action research design incorporated both collaborative sense-making and disruptive gaze. Analysis draws on interpersonal and observational data gathered purposively from multiple perspectives in 11 Real Time projects between 2006 and 2008. Five were youth projects and six with adults, two were women-only and one men-only, two with learning-disabled adults and four aimed at minority-ethnic participants. Participatory video as facilitated empowerment practice led to new social becoming by opening conducive social spaces, mediating interactions, catalysing group action and re-positioning participants. Videoing as performance context had a structuring and intensifying function, but there were parallel risks such as inappropriate exposure when internal and external dialogical space was confused. A rhizomic map of Real Time’s non-linear practice territory identifies eight key practice balances, and incorporates process possibilities, linked tensions, and enabling and hindering factors at four main sequential stages. Communicative action through iteratively progressing video activities unfolded through predictable transitions to generate a diversifying progression from micro to mezzo level when supported. This thesis thus shows how participatory video is constituted afresh in each new context, with the universal and particular in ongoing dynamic interchange during the emergent empowerment journey

Set in Stone: Building America's New Generation of Arts Facilities, 1994-2008

In 2007, just before the domestic economy experienced a major trauma, the Cultural Policy Center at the Harris School and NORC at the University of Chicago launched a national study of cultural building in the United States. It was motivated by multiple requests from leading consultants in the cultural sector who found themselves involved in a steadily growing number of major building projects -- museums, performing arts centers (PACs), and theaters -- and from foundation officers who were frequently asked to help fund these infrastructure projects. With the generous support of the Andrew W. Mellon Foundation, the Kresge Foundation, and the John D. and Catherine T. MacArthur Foundation, we were able to conduct systematic scientific research on cultural building in the United States between 1994 and 2008 and come to a number of conclusions that have important implications for the cultural sector

Cultural capital investment interim impact evaluation

This report provides interim impact evaluation evidence on a major initiative to develop the quality and opportunity of cultural provision in the East Midlands. Eight venues across the region have been supported through an investment totalling £120 million, which include a mix of brand new buildings and bringing new life to existing facilities. This report sets out what the investment has achieved so far and how information on the impact of the venues will be collected in the future

Evaluating megaprojects: from the “iron triangle” to network mapping

Evaluation literature has paid relatively little attention to the specific needs of evaluating large, complex industrial and infrastructure projects, often called ‘megaprojects’. The abundant megaproject governance literature, in turn, has largely focused on the so-called ‘megaproject pathologies’, i.e. the chronic budget overruns, and failure of such projects to keep to timetables and deliver the expected social and economic benefits. This article draws on these two strands of literature, identifies shortcomings, and suggests potential pathways towards an improved evaluation of megaprojects. To counterbalance the current overemphasis on relatively narrowly defined accountability as the main function of megaproject evaluation, and the narrow definition of project success in megaproject evaluation, the article argues that conceptualizing megaprojects as dynamic and evolving networks would provide a useful basis for the design of an evaluation approach better able to promote learning and to address the socio economic aspects of megaprojects. A modified version of ‘network mapping’ is suggested as a possible framework for megaproject evaluation, with the exploration of the multiple accountability relationships as a central evaluation task, designed to reconcile learning and accountability as the central evaluation functions. The article highlights the role of evaluation as an ‘emergent’ property of spontaneous megaproject ‘governing’, and explores the challenges that this poses to the role of the evaluator

What lessons can be transferred to higher education learning landscapes from the leadership, governance and management processes of school design projects?

This review reports experiences from the schools sector in involving stakeholders in the processes of managing school building design. Its aim was to see if any of this could offer guidance for higher education as their learning landscapes are reconceptualised. School architects and designers have gradually accepted grater stakeholder involvement especially from pupils and to a lesser extent from teachers and many innovative ways have been found to make their participation authentic. These could be adapted in higher education together with teacher education in new pedagogies and better liaison with governors

Examining the Development Effects of Modern-Era Streetcars: An Assessment of Portland and Seattle

Most U.S. cities pursuing streetcars are doing so primarily for their purported development effects, as opposed to for their transportation role, yet there is little evidence about the nature or magnitude of these development effects due to a scarcity of rigorous, empirical research. Most available work simply presents descriptive information about development outcomes (typically measured as changes in population, employment, land values, or permit activity) within streetcar corridors as indicators of the streetcar’s development effects. Alternate factors which may have influenced such results are often not considered, placing into question the validity of such measures.This study examines the development effects of streetcar investments in two U.S. cities that implemented streetcar service between 2000 and 2010: Portland, Oregon, and Seattle, Washington. The authors explore the development outcomes (here measured as the number of permits issued) through a combination of statistical analysis of development activity in the streetcar corridor and interviews with key streetcar stakeholders. The statistical results indicate that areas around Portland’s initial streetcar line experienced higher levels of development activity (more permits issued) than areas not served by the streetcar, although the differences in activity between served and not served areas since the opening of the second line have been insignificant. In Seattle, the areas around the streetcar line in the South Lake Union neighborhood experienced greater commercial development activity (commercial permits issued) but less residential activity than nearby unserved areas. The interviews provide important local context for the interpretation of the empirical results and highlight the continued importance of development as a rationale for streetcar investments, as well as to the limitations of the streetcar as a transportation service

Design strategies in facades for the reduction of housing energy consumption

This article analyzes the energy-saving potential of various facade design strategies from a life cycle perspective, including the energy needed in the use stage and the embodied energy of materials. The results provide reference data on the behaviour of these systems in Spain and make it possible to identify the best strategies for reducing energy consumption in a wide variety of potential situations that may arise in both new construction and in the rehabilitation of existing facades. The impact categories studied are fossil fuel depletion and climate change, and design strategies are linked to climate data, orientation, air change rate, facade materials and wall composition. Exchanges between the interior and exterior environments take place through the building envelope, some of whose key design parameters include lighting, ventilation and heat flux. Improving this envelope can greatly reduce environmental impact, ensuring indoor environmental quality. This analysis confirms the need to consider the interactions among the parameters studied, as it shows that there are several design solutions with similar impacts, which can be adapted to project requirements. In both new construction and rehabilitation, some of these parameters may be determined by other design decisions not necessarily aimed at reducing environmental impact, so it can be very useful to be aware of a variety of design alternatives that can be implemented in specific projects
