Evaluation Of Accessibility To Primary Schools

There are a lot of examples of some common resource allocation dilemmas for public facility faced by planners and policymakers everywhere. Policymakers need have an insight in how well current facilities perform, and then decide how to improve the performance to ensure the service is provided at the most effective location where the demand is the mostCurrently, the conventional planning method is used popularly, but it does not incorporate the concept of accessibility and cannot give accurate demand-supply information. In this point, a more detailed method is a useful tool to analyze accessibility.Yuhua district in Changsha, China is selected as the study area in this research. This thesis evaluates the accessibility to public primary school in the current situation and in the plan of the year 2020, in terms of supply and demand from two perspectives: spatial distribution and capacity, integrated accessibility theory and GIS. It also proposes patterns to improve the accessibility to public school by selecting acceptable service centre locations. Coverage percentage is used to guide the quantifying of performance and the comparisons of the demand and supply is used as the supplement of performance. To investigate the advantage of the integration of accessibility theory and GIS, the comparisons between the current situation, the plan and the proposed pattern are carried out in this research. These results may give reason for a selection among different plan alternatives and location new service centres.The results indicate the accessibility analysis can reflect the relationship between the supply and demand in more detailed than conventional method. The results also prove the developed method is an effective way to evaluate accessibility and to propose acceptable centre location and to suggest proper capacity of public facility. Integrated with GIS, it is easy to delineate the serviced and unserviced area and to interpret the results.
