The archtype and the idealGreen, Carter B. January 1991 (has links)
The location for the project is in the downtown area of Staunton, Virginia, a small town in the Shenandoah Valley. The site is a parking lot with a wall of nineteenth century warehouse buildings on one side that suggest the completion of a public square.
The means by which l tried to find a resolution to this architectural suggestion involve a historical search for connection as well as a vision for the future. The circumstantial demands of place and occasion allow the project to materialize between the archetype and the ideal. / Master of Architecture

Traffic Safety Assessment of Different Toll Collection Systems on Expressways Using Multiple Analytical TechniquesAbuzwidah, Muamer 01 January 2014 (has links)
Traffic safety has been considered one of the most important issues in the transportation field. Crashes have caused extensive human and economic losses. With the objective of reducing crash occurrence and alleviating crash injury severity, major efforts have been dedicated to reveal the hazardous factors that affect crash occurrence. With these consistent efforts, both fatalities and fatality rates from road traffic crashes in many countries have been steadily declining over the last ten years. Nevertheless, according to the World Health Organization, the world still lost 1.24 million lives from road traffic crashes in the year of 2013. And without action, traffic crashes on the roads network are predicted to result in deaths of around 1.9 million people, and up to 50 million more people suffer non-fatal injuries annually, with many incurring a disability as a result of their injury by the year 2020. To meet the transportation needs, the use of expressways (toll roads) has risen dramatically in many countries in the past decade. In fact, freeways and expressways are considered an important part of any successful transportation system. These facilities carry the majority of daily trips on the transportation network. Although expressways offer high level of service, and are considered the safest among other types of roads, traditional toll collection systems may have both safety and operational challenges. The traditional toll plazas still experience many crashes, many of which are severe. Therefore, it becomes more important to evaluate the traffic safety impacts of using different tolling systems. The main focus of the research in this dissertation is to provide an up-to-date safety impact of using different toll collection systems, as well as providing safety guidelines for these facilities to promote safety and enhance mobility on expressways. In this study, an extensive data collection was conducted that included one hundred mainline toll plazas located on approximately 750 miles of expressways in Florida. Multiple sources of data available online maintained by Florida Department of Transportation were utilized to identify traffic, geometric and geographic characteristics of the locations as well as investigating and determination of the most complete and accurate data. Different methods of observational before-after and Cross-Sectional techniques were used to evaluate the safety effectiveness of applying different treatments on expressways. The Before-After method includes Naive Before-After, Before-After with Comparison Group, and Before-After with Empirical Bayesian. A set of Safety Performance Functions (SPFs) which predict crash frequency as a function of explanatory variables were developed at the aggregate level using crash data and the corresponding exposure and risk factors. Results of the aggregate traffic safety analysis can be used to identify the hazardous locations (hot spots) such as traditional toll plazas, and also to predict crash frequency for untreated sites in the after period in the Before-After with EB method or derive Crash Modification Factors (CMF) for the treatment using the Cross-Sectional method. This type of analysis is usually used to improve geometric characteristics and mainly focus on discovering the risk factors that are related to the total crash frequency, specific crash type, and/or different crash severity levels. Both simple SPFs (with traffic volume only as an explanatory variable) and full SPFs (with traffic volume and additional explanatory variable(s)) were used to estimate the CMFs and only CMFs with lower standard error were recommended. The results of this study proved that safety effectiveness was significantly improved across all locations that were upgraded from Traditional Mainline Toll Plazas (TMTP) to the Hybrid Mainline Toll Plazas (HMTP) system. This treatment significantly reduced total, Fatal-and-Injury (F+I), and Rear-End crashes by 47, 46 and 65 percent, respectively. Moreover, this study examined the traffic safety impact of using different designs, and diverge-and-merge areas of the HMTP. This design combines either express Open Road Tolling (ORT) lanes on the mainline and separate traditional toll collection to the side (design-1), or traditional toll collection on the mainline and separate ORT lanes to the side (design-2). It was also proven that there is a significant difference between these designs, and there is an indication that design-1 is safer and the majority of crashes occurred at diverge-and-merge areas before and after these facilities. However, design-2 could be a good temporary design at locations that have low prepaid transponder (Electronic Toll Collection (ETC)) users. In other words, it is dependent upon the percentage of the ETC users. As this percentage increases, more traffic will need to diverge and merge; thus, this design becomes riskier. In addition, the results indicated significant relationships between the crash frequency and toll plaza types, annual average daily traffic, and drivers* age. The analysis showed that the conversion from TMTP to the All-Electronic Toll Collection (AETC) system resulted in an average reduction of 77, 76, and 67 percent for total, F+I, and Property Damage Only (PDO) crashes, respectively; for rear end and Lane Change Related (LCR) crashes the average reductions were 81 and 75 percent, respectively. The conversion from HMTP to AETC system enhanced traffic safety by reducing crashes by an average of 23, 29 and 19 percent for total, F+I, and PDO crashes; also, for rear end and LCR crashes, the average reductions were 15 and 21 percent, respectively. Based on these results, the use of AETC system changed toll plazas from the highest risk sections on Expressways to be similar to regular segments. Therefore, it can be concluded that the use of AETC system was proven to be an excellent solution to several traffic operations as well as environmental and economic problems. For those agencies that cannot adopt the HMTP and the AETC systems, improving traffic safety at traditional toll plazas should take a priority. This study also evaluates the safety effectiveness of the implementation of High-Occupancy Toll lanes (HOT Lanes) as well as adding roadway lighting to expressways. The results showed that there were no significant impact of the implementation of HOT lanes on the roadway segment as a whole (HOT and Regular Lanes combined). But there was a significant difference between the regular lanes and the HOT lanes at the same roadway segment; the crash count increased at the regular lanes and decreased at the HOT lanes. It was found that the total and F+I crashes were reduced at the HOT lanes by an average of 25 and 45 percent, respectively. This may be attributable to the fact that the HOT lanes became a highway within a highway. Moreover adding roadway lighting has significantly improved traffic safety on the expressways by reducing the night crashes by approximately 35 percent. Overall, the proposed analyses of the safety effectiveness of using different toll collection systems are useful in providing expressway authorities with detailed information on where countermeasures must be implemented. This study provided for the first time an up-to-date safety impact of using different toll collection systems, also developed safety guidelines for these systems which would be useful for practitioners and roadway users.

Placemaking : a city plaza in downtown Muncie that celebrates its heritageCui, Jing January 2001 (has links)
There is a phenomenon of placelessness. Cities have look-alike landscapes. This sameness leads to a lack of significant places and a loss of sense of place. In addition to that, with the suburban sprawl and downtown deterioration, there is an increasing need for downtown revitalization. Cities call for vibrant and pleasant places with characters.In a world where most cities are getting more similar with each other and where people can't tell whom they are and where they come from, placemaking actions should be welcomed. Placemaking respects the genius of the place and finds links between traditions and our present experience of life.This thesis presents an overview of placemaking including its definition, history, categories, functions, principles and actions. Its purpose is to apply placemaking into the design of a city plaza in downtown Muncie to make a place that links people to history, to culture, and to other people. By doing that, this creative project tries to illustrate that placemaking is a valuable strategy in urban regeneration. / Department of Landscape Architecture

La plaza en la ciudad histórica. Análisis tipológico de la plaza histórica en la Región de Murcia. Criterios de intervenciónRódenas Cañada, José María 05 May 2022 (has links)
[ES] El objeto de estudio de la presente tesis es la plaza urbana en el contexto de la ciudad histórica, entendida como espacio urbano históricamente configurado y aceptado socialmente como tal. El estudio se centra en la plaza como elemento estructurante de la ciudad, relacionada con su constitución, origen y principios organizadores. Se analizan las intervenciones planificadoras sobre la ciudad histórica tratando de descubrir criterios de intervención en el patrimonio urbanístico aplicables al ejercicio y la práctica profesional, en un estudio centrado en los límites administrativos de la Comunidad de Murcia. La práctica del urbanismo se considera en el marco de este estudio, como una actividad necesitada de criterios de actuación al margen de las determinaciones legales y reglamentarias de obligado cumplimiento. No se trata de expedir recetas, sino de encontrar principios y fundamentos para una práctica urbanística responsable.
Esta tesis quiere servir también para divulgar los valores del patrimonio artístico, maltratado muchas veces por actuaciones incontroladas de la administración, a quien compete poner en marcha programas de recuperación de espacios públicos como piezas significativas de la ciudad histórica, al tiempo que se potencia una "cultura espacial" que contribuya a enriquecer estéticamente nuestro entorno urbano. / [EN] The subject of this thesis is the urban square in the context of the historic city, understood as an urban space historically configured and socially accepted as such. The study focuses on the square as a structuring element of the city, related to its constitution, origin and organizing principles. The planning interventions on the historic city are analyzed trying to discover criteria of intervention in the urban heritage applicable to the exercise and professional practice, with a focus on the administrative limits of the Community of Murcia. The practice of urban planning is considered within the framework of this study as an activity in need of performance criteria outside the legal and regulatory determinations of mandatory compliance. It is not about using pre-made formulas, but about finding principles and foundations for a responsible urban practice.
This thesis also wants to serve to spread the values of artistic heritage, mistreated many times by uncontrolled actions of the government administration, which is responsible for launching recovery programs for public spaces as significant pieces of the historic city, while promoting a "spatial culture" that contributes to aesthetically enriching our urban environment. / Ródenas Cañada, JM.

MeetingsNienstedt, Uwe January 1987 (has links)
The thesis consists of two parts:
The introduction states a rationale for the making of Architecture by defining its final and subsidiary goals and identifying the importance of ‘judgement’ and the concept of ‘order’ as operational means.
The project attempts to apply the theory on three different scales: object, building and urban. This part of the book is structure around the theme of ‘meetings’, the enjoyment of two entities coming together and in various ways interacting and redefining each other architecturally. / Master of Architecture
