Application of Geographic Information System Technology to Conduct Traffic Evaluation of Ancient City of Suzhou, China

One of the main tasks of urban regeneration is to determine the function and development intensity of the redevelopment of urban stock land. Renewal of the inappropriate traffic location disturbs the traffic and makes it difficult to increase the land value. Therefore, the spatial location and development intensity of the urban area need to be developed considering traffic capacity and demand. This enhances land value after development and promotes sustainable development and organic renewal. Application of Geographic Information System (GIS) coupling with the coordination pattern evaluation system was also required. For the evaluation of traffic supply and demand, the entropy weight method was used to measure three indexes: road network density, traffic accessibility, and traffic facility service level. Traffic capacity demand was measured by the amount of travel generated by different types of land uses. The coupling coordination model was used to evaluate the balance between the supply and demand of traffic capacity. According to the mixing degree and regulation law of land use, the optimal control of land use and the road was proposed to provide a basis for decision-making on the regeneration and construction of the ancient city.
