This study identifies the critical variables for determining route construction priorities (RCP) in a common duct network (CDN) using expert interviews and questionnaire surveys. Statistical analysis is also conducted to check the validation and verification of the survey results. Furthermore, factor analysis is employed to derive 24 priority determinant variables and classify them into five groups, including utility agency, traffic condition, local government, infrastructure project, and site condition. The paired comparison method is then employed to determine the weightings of the five groups. It is found that the utility agency is the most important factor while the site condition is the least important one in determining RCP for a CDN. An assessment model for ranking the RCP in a CDN is developed. A six-route CDN in northern Taiwan is analyzed using the proposed model, with multiple viewpoints being considered to ensure the objectivity of the analytical results.
