Abstract

In the quest for a special tool for lowland urban growth model, we have developed a model of a city based on the analogy of biological cell growth using the extension of the stochastic growth Eden simulation. In this paper, we described the theoretical observable fact on how a city grows if the land is flat and there is no natural barrier for the development. Similar researches on cellular urban growth are reviewed and we showed how they are different from our model. Urban growth model development using the extension of the Eden model as analogues to biological cell growth is explained. The model is applied to simulate a hypothetical unconstrained city development. The simulation results shows that for a mono-centric city without any development constraint, the expansion rate of the city area is equivalent to the ratio of the perimeter per area of the city. This result may be useful to predict the approximategrowth rate of any city without any prior knowledge of the historical data. Furthermore, it was found that the growth of an unconstrained city is almost circular with a decreasing rate of the mean radius growth.

Abstract

Public parks are one of the representatives of urban environment that play an essential role to daily life of people and provide a variety of benefits and opportunities for community as green spaces. The lack of understanding of associations between pattern of park utilization and users’ preference has made difficulties to highlight the role of public parks in community while reflecting social needs of park users. To reflect actual preference of park users, Saga city in Japan was selected as a case study by employ an unconventional method to capture the real preference from actual target group of public park service. An indirect value of park users’ benefits estimation has been done through the determination of preference value factor, PVF in different users’ socioeconomic and recreation activity characteristics. The uniqueness of this method is to focus on the linkages between the availability of public parks and social preferences. On the basis of findings, the results pointed out that not only different satisfaction on park service induce on the differentiation of PVF value but the different willingness to pay on maintenance and management park service also result to demonstrates an different intuitive appreciation for environmental valuation based on park visitors’ preference.

Abstract

An urban growth model using stochastic cellular simulation was developed with motivation to understand the consequence of zone management policies in lowland cities. The model could integrate the growth, decline, spread, intensification, and protected areas of the urban growth into a single generalization of both the Eden and the p-models. Calibration strategy was demonstrated using historical aerial photographs of Saga city, Japan.

Abstract

Public parks provide a numerous benefits and opportunities for community and however, to maintenance of public parks need large amount of local governmental budget. This study investigates park users’ preference on willingness to pay to quantify recreational benefit of public parks. A new assessment method was proposed to verify the consistency of data collection by utilizing the relatively simply technique, we called string method. Based on this approach, a case study of three public parks in Saga city, Japan was established to qualify users’ view that could enable us to evaluate their participation on the improvement of accessibility and attractiveness of park according to community needs. The result indicated that different patterns of recreational travel and activity on park visitation induce in different compensation on public activities’ program. This useful information could be utilized to guide local planning agency to locate suitable policy for public park service improvement.

Abstract

Many planners have recently utilized the Development Impact Assessment framework focuses on the site specific level, and mostly concerns only limited types of development impacts. In fact, the city growths are the results of simultaneous developments and their adverse impacts are diverse, such as economic losses and environmental degradations. These become the limitations of impact assessment to manage the actual urbanizations. We have developed a framework of Zonal Impact Assessment (ZIA) to evercome those limitations. Our framework mainly evaluates the generated impacts in each zone rather than an isolated project. The ZIA can analyze the impacts of simultaneous developments in many zones, and many kinds of impacts can be considered. Furthermore, the survey results of public participation were included to identify the sensitive areas for development impact based on the preferences of zonal communities. The Bangkapi case study was elucidated to demontrate the ZIA application concerning traffic impacts of developments. The Impact distributions were evaluated and visualized for planning process. It wa found that ZIA is an alternative tool in balancing between infrastructure demands and urban developments to reach a sustainable community.
