A Study on Network Game Simulation of Urban Large Pak Re-development and Preference Characteristics of Park Planner

最古老的国家政府公园建于大约30年前。由于公园设施的老化和社会需求的变化，城市大型公园失去了原有的功能。因此，我们必须对这些老公园进行更新设计和改造。但是我们没有一个公园再开发设计的方法。我们不能在短时间内制定太多的更新计划。因此，很难选择一个最好的或适当的方案，有一个很好的平衡成本，功能和景观。本研究项目旨在开发互动运作的网络游戏，作为公园再开发规划决策支持系统的工具。作为案例研究，我们选择了冲绳政府公园（海洋博览会纪念区），并收集了公园设施、成本和景观的真实数据。我们设计了一个网络仿真游戏，并成功开发了一个原型系统。这个游戏系统由三个部分组成。第一部分是布置引擎（在电脑屏幕上布置公园设施和修改地形），第二部分是参数引擎（设施规格和成本数据库），第三部分是可视化引擎（3D-CG景观可视化）。这些发动机是相互独立的，所以我们可以根据对方园区的数据来更换每个发动机。各园区的规划是相互独立的，所以我们可以根据其他园区的重新开发来更换每个引擎，很容易通过重复的尝试和错误将园区设施剪切粘贴在电脑屏幕上。日志数据通过每个玩家的游戏动作存储在服务器中，从而掌握每个玩家的偏好特征与公园功能有效性、成本与景观、合理性之间的关系。但是，对这些日志的精确调查尚未执行，因此这是未来研究的主题。

The oldest National Government Park has constructed about 30 years ago. Such urban large park loses their function by ageing of park facilities and change of social needs. So we must plan the renewal design of such old parks and execute their reconstruction. But we don't have a method of park redevelopment designing. We can't make many plan of renewal in short period. So, it is difficult to choose the best or proper plan that has a good balance of cost, function and landscape. This research project aims to develop the network game of interactive operation as a tool of the planning decision support system of park redevelopment. For a case study, we chose The OKINAWA Government Park (Ocean Exposition Commemorative Area) and gathered real park data of facilities, costs and landscape. We designed a network simulation game and succeeded to develop a prototype system. This game system is composed by three components. First component is the arrangement engine (Arranging park facilities and modify landform in the computer screen), the second is the parameters engine (Database of facilities specifications and costs), and the third is the visualization engine (Landscape visualization by 3D-CG). Those engines are independent each other, so we can replace each engine according to the other park's data. The park planner are independent each other, so we can replace each engine according to the other park redevelopment easily to cut and paste the park facilities in computer screen by repetition of try and error. Log data are stored in server by every action of playing game, so we can grasp the relationships between preference characteristics of each player and effectiveness of park function, cost and landscape, rationality. But, the precise investigation of those logs is not executed yet, so it is the subject of future research.
