Road Network and Medical Facilities Planning Model Considering Accessibility and Connectivity

Abstract

 This study aims at establishing a planning model to improving the robustness of road network against the risk of link destruction in terms of both network topology and the arrangement of medical facilities. A new measure for evaluating network robustness is first established, by applying the concepts of connectivity reliability and accessibility. By using the measure, a planning model, which identifies the optimal combination of road network topology and opportunity arrangement ensuring the robustness, is developed. Finally, the model is applied to Kyoto Prefecture road network and it reveals that the risk of link degradation significantly affect the optimal solution.
