Evaluation of green transport systems by importance-performance analysis approach

This paper presents the findings of a green transport study for a new development area in Hong Kong. In the study, various motorized green transport modes have been investigated together with discussion on the pros and cons of these alternative modes. Questionnaire surveys have been conducted to collect expert views and opinions from both local and overseas potential stakeholders on different motorized green transport modes. With the use of importance-performance analysis approach, electric bus was found to be the most feasible motorized green transport mode for new development area. The results show that, in general, electric bus performs well on four important criteria including service requirement, financial and economic, environmental, and social and implement-ability considerations. In comparison, monorail and modern tram/light rail have good performance on the criteria particularly on the service requirement and environmental considerations. Recommendations are made on the green transport system for the selected new development area based on the survey results.
