Some considerations on urban redevelopment and traffic accessibility

Improvement of the urban road network, especially constructions of new arterial roads, effects on the urban structure, e.g., land use, location of urban facilities, population distribution and so on. In this sutdy, Ube City was chosen as an object of investigation and its urban redevelopment is discussed from the viewpoint of traffic accessibility. The south area of the city was divided into 100m×100m meshes and ground height of each coordinate point and land use of each mesh area were surveyed. These were used as input data for a personal computer program developed for this study. Some mesh maps, such as a topography of the city, land use and access time distribution of the city, are drawn up by a computer and the relationships between the topographic feature and land use are analyzed based on these data. The secular change of land use is investigated bsed on the mesh maps. The change of traffic accesssibility to the city center from each district of the city caused by the construction of new arterial roads was also analyzed and the area to be developed as the central district in the future was discussed and its optimal location proposed based on the road network pattern.
