Although there have often been discussions on the recovery of development gains, mainly the land price increase, from the viewpoint of financial sources, it is yet rare to establish such a system specialised for transport projects. The urban economists, on the other hand, say that the condition that all the transport benefits accrue to the land price increase is if and only if, the affected area be small-open and large-closed city so that only a part of total transport benefit results in the land price increase and the remaining one in the form of transport users' benefit. It is essential, therefore, to measure the relative share of landowner's benefits over the total social benefits derived by transport project in order to establish the recovery systems of development gains. Looking at the present situation on the practical models from the above viewpoint, one of the applicable study field is the transport- land use interaction modelling. The conventional land use models have total benefits based on the conceptually correct definition of transport benefits mainly due to their model structure lack of general equilibrium approach. Because of these problems the authors have developed a theoretical model to analyze the structure from benefit generation to its incidence within the framework of multi-regional general equilibrium approach by taking into account the random residential and industrial location theory. This paper applies this conceptual model to the case study on measurement of the benefit incidence of ring road construction in Gifu City, Japan in order to analyze the variety of degree of small-open and its reason depending on their locational conditions for each zone 22, thereby construct a formula between the ratio of landowner's and of transport user's benefit depending on their locational conditions.
