Application of Success Factor Model for Green Highway Projects in Malaysia

Green highway is a management concept of an expressway project during the planning, design and construction stages. This concept combines transportation and ecological sustainability which is the backbone of the transportation system, ecosystem, municipal well-being and town development. The implementation of green highway in an expressway design is a critical initiative towards the achievement of Sustainable Development Goal (SDGs). The Malaysia Green Highway Index (MyGHI) manual was introduced to support the green highway in the Malaysian context. However, MyGHI is relatively new to such endeavors and a mechanism to measure a successful green highway is still lacking. The purpose of this study is to provide an integral knowledge on the factors influencing green highway implementation and determine the level of importance for each factor. Model constructs were introduced and established from the literature concept and theory as well as from exploratory data using the qualitative approach. Transcribed interview data analysis was analysed using Nvivo, Microsoft Excel and Critically Index assessment. It was found that three factors that affect the success of green highway are innovation; construction activities; and material and resources. Twelve experts from government and private agencies participated in contributing to factors and perspectives towards multiple theories and concepts to produce the green highway model. Hence, the idea of developing a model for a green highway is valid and justified, but is limited to the expressway in the Malaysian context.
