Sustainability SI: Bikeway Network Design Model for Recreational Bicycling in Scenic Areas

A bikeway network design model was developed for recreational bicycling in scenic areas. The multi-objective 0–1 programming problem is to determine spatial layouts for networks of bikeways and service stations. The model objectives are maximizing bikeway service coverage, maximizing service station service coverage, minimizing cyclist risk and maximizing bikeway suitability. The model constraints are network connectivity, bikeway type, monetary budget, location relationships between bikeways and service stations, and value ranges of decision variables. The programming problem was solved by ε-constraint method in a case study of a bikeway network in North Coast & Guanyinshan National Scenic Area in northern Taiwan. Four of the six non-dominated alternatives generated in the case study were substantially superior to existing bikeways, and budget limits sensitively affected cyclist risk and bikeway suitability. The proposed network design model for recreational bikeways can assist planners in efficiently and systematically developing alternatives for further evaluation.
