Biological system: The Oxalis Plant (Oxalis Oregana)

Name: Yang Jing Loo

Introduction

 

Today, pedestrians have to travel at every corner of urban City Centre to fulfill their needs. Walking is considered as one of the oldest non-motorized modes of transportation. A major deficiency, especially in the City Centre, is lack of the accessibility pedestrian network. An urban City Centre is not a pedestrian friendly city if its lack of pedestrian network and existence of major deficiencies such as poor maintenance and accessibility (Jin and Overend, 2014). Promoting walking and cycling is important when the urban population tends to depend on private motorized vehicles for moving around. Motorized vehicles contribute to air pollution, global warming, and climate change. Sustainable transportation such as walking and cycling can help reduce these problems. However,  promoting walking among the cities is not an easy task, especially in countries  with  hot climates like Malaysia.  A typical tropical climate has high ambient air temperatures and relative humidity year round, with a diurnal maximum temperature of 31°C to 34°C and a minimum of 23°C to 26°C (on Climate Change, 2014). On top of this, the heat increases by 0.25°C in the city areas. Heat and polluted environments contribute to the fact that not many people prefer to walk. Relatively, this relates to pedestrian comfort. In other words, if the weather is hot and the air is moist with humidity, it is very unlikely that a pedestrian is going to enjoy walking on streets. The rough definition of pedestrian comfort is the pleasant feeling that people feel when they interact with the environment. Walking is the most basic mode of getting from one point to another and the most convenient way for pedestrians to move to their destination. Nevertheless, in order to encourage them to walk, the street built environment has to provide a safe and comfortable landscape for walking. This research study is to propose a sustainable multipurpose shading device that is able to promote walkability by studying the behavioral pattern of Oxalis plant.
