Abstract
For exploring the impact of high-speed rail construction on urban accessibility pattern and spatial equity, this paper takes Triangle of Central China as an example, and takes counties and cities as objects to compare and analyze the two travel modes of driving and high-speed railway. Firstly, a model is established for the travel time of driving and high-speed rail by using Baidu map data and high-speed train information. Then the weighted average travel time and economic potential are adopted to evaluate the accessibility level and analyze the accessibility pattern. Furthermore, the coefficient of variation is used to evaluate the spatial equity of accessibility. Key conclusions include: The high-speed rail construction has significantly improved the accessibility of Triangle of Central China; In driving mode, the accessibility level in the middle areas is higher, and Wuhan, Changsha and Nanchang are the three regional centers of high accessibility, while in the high-speed rail mode, the high accessibility area forms a triangular hollow ring structure with Wuhan, Changsha and Nanchang as the vertices and the high-speed rail line as the side; High-speed rail strength-ens the spatial imbalance, with the unbalanced growth of Hubei is the biggest, and prefec-ture-level cities benefit more from high-speed railway.
