The Impact of Rivers and Lakes on the Expansion of Urban Traffic: A Case Study of Traffic Evolution in Wuhan, China in the Past Century

Rivers and lakes have always had a profound impact on the expansion of urban traffic. The authors take the traffic evolution in Wuhan, China in the past century as an example to explore the relationship which is from "strong connection" to "weakening connection" to "restriction" to "reciprocity" between water and urban traffic, and then analyze the influence mechanism of rivers and lakes on different development stages of urban traffic. In this regard, the authors choose the road network of Wuhan in 1922, 1975, 1997 and 2019 as the research object, and analyzes the change characteristics of riverside traffic and lakeside traffic in the process of urban expansion through the setting of water buffers. The authors revise the traditional Shortest-Path Model and propose the new concepts of "Detour Index" and "Weighted Detour Index" to explain the road accessibility of each node in the city based on its own environmental characteristics, based on these the authors evaluate the possible impact of water as "obstacles" on the road network in different stages of urban development.
