Abstract
The concept of privately owned public space(POPS) tends to make site layout plans having a positive effect on the urban environment. However, developers often only take it as a way to pursuit total floor area maximisation, which in turn increases the negative impact on cities.Hence, this study analyses the rule behind such phenomenon by an operations research approach. The operations research model sets the measurement of layout plans as the decision variables, the regulations as the constraints, the pursuit of total floor area maximisation development as the objective function. Then, test the model in various building sites conditions, such as building floor area ratio and building coverage ratio, area, shape and the terms of the adjacent roads.
This study establishes five layout planning theorem. (1) The height restriction of buildings depends on the floor area ratio restriction and sites area, is either 50m or 100m. (2) The height of the building equals to height restriction. (3) The actual coverage ratio equals to either 1/7 or 1/14 of the floor area ratio restriction. (4) The open space area equals to 1/3 of the site area. (5) The width of the trail type open space is proportional to the length of the edge of the building site which adjacent to the road.
As a conclusion, we find that the pursuit of total floor area maximisation has a decisive influence on layout plans. In contrast, other planning instruments tools have been struggled to lead layout plans.
