Exploration assessment of the service distance based on Geographical Information Systems and Space Syntax analysis on the urban public facility

Public facility allocation would improve the quality of the urban environment. An accurate service distance of the public facility would improve the plan location of the public facility Recently, the road network structure was complicated and unequally developed The issues of the road involve the carrying capacity effect and the traveler choice behavior, however past studies evaluating the service distance use the straight distance method that was too simple to describe the true situation. This paper aims at using Geographical Information Systems of the network analysis integration of the Space Syntax analysis to measure the road integration value. The result of the road network integration affect the service distance, this is called the marginal ring to offer practice and discussed in the concluding section.
