Abstract

The purpose of this research was to analyze the accessibility efficiency of transportation network of Chiang Mai comprehensive plan and Chiang Mai city at the present for appropriate land use guidelines. The study was undertaken by theory and Space Syntax technique, Geo-Informatics System, field surveying and document analysis. It was found that the transportation network of Chiang Mai comprehensive plan and Chiang Mai city at the present were in the main form of a grid, radius and ring roads linking from the city center to suburb. The average accessibility efficiency of transportation networks was 0.214098 with the minimum of 0.087010 and the maximum of 0.323663 respectively. A high accessibility efficiency of transportations network was Highway no.1 (Superhighway Road). The junction of ring and radius roads had accessibility efficiency in accordance with the regulation of land use for commercial purposes and high-density, medium-density and low-density residential areas. However, such findings were not true for the junction of ring and radius roads in the north, east and south directions of the city where the high accessibility efficiency was found in rural and agricultural areas. At the present, the average of accessibility efficiency index of Chiang Mai transportation networks was 0.464700, while its minimum and maximum indexes were 0.122850 and 0.725260, respectively. The roads that had high accessibility efficiency were the Highway no.1 in the center of the city and the radius roads from the city center to suburb. Their efficiency accessibility indexes were 0.658449–0.725264 which were in accordance with existing building and construction uses at the present for commercial purposes and high-density, medium-density and low-density residential areas. However, it was found a common accessibility efficiency along the junction of the ring roads and the radius roads around the city and that of the transportation network of Chiang Mai comprehensive plan through the country and agricultural areas. Both had impacts on scattering urban development in the countryside and suburb areas. The main effect was the result from the aforementioned accessibility efficiency indexes and there should have a measure to control the land use in the future in order to reduce the impacts of development the countryside and suburb agricultural areas.
