Analytical Research of Public Transportation Accessibility on the Wushan Campus of South China University of Technology

As China's city development shifts from high-speed growth to high-quality development, the rational and coordinated construction of public transportation has become one of the most important directions to urban land and space planning and transformation development. By consulting on the highly effective Public Transport Access Level (PTAL) Technology in London, a quantitative analysis method can be found to evaluate the rationality of public transport and land-use layout, thereby supporting the sustainable development of the city. This article firstly summarizes the basic steps of London's PTAL technology and then applies these methods to the public transportation accessibility evaluation on the Wushan Campus of South China University of Technology (SCUT) in Guangzhou. PTAL values and relevant maps generated by those methods can quantitatively measure the supply level of public transportation, which provides a reference for the construction and optimization of public transportation stations and lines.
