Derivation of Path Ranking in Graph Based on Route Activity Level of Network

抄録

In this paper we propose extended spatial interaction model permitting consideration of several path selection for each origin-destination pair. The spatial interaction model is known as a general model because it has been developed by entropy maximization principle. From observed data about traffic flow, our model can estimate traffic volume from origin to destination. It can be regarded as a merged concept between the geographical advantage and accessibility of the spatial interaction model in unified way. The parameter estimation procedure for the proposed model is developed. The availability of our model that can consider not only a network structure but also a traffic flow is shown.
