A Design Optimization Index for Two Types of Cycleways

Abstract Amid rising environmental awareness, sustainable and low-carbon traffic tools are attracting considerable attention. Increasing worldwide use of bicycles for both leisure and basic transportation has increased the importance of public bicycle-related infrastructure, notably cycleways. This paper proposes a Design Optimization Index for two types of cycleways, i.e., those that are used primarily for commuting, and those that are mostly for leisure. Based on a literature review, the researchers initially developed 27 impact factors. Then, through the fuzzy Delphi method of collecting and refining advice from a group of experts, these were integrated into a five-part structure consisting of “security”, “convenience”, “environmental friendliness”, “comfort” and “attractiveness”, which can be further broen down into 16 factors in the case of commuter cycleways, and 15 factors in the case of leisure cycleways.
