The transportation corridor of the Wuhan Metropolitan Area serves as the core carrier for regional coordinated development, and its service capacity directly affects the metropolitan area‘s integration process. This paper constructs an evaluation index system for transportation corridor service capacity from five dimensions: infrastructure, transport service, safety, economic benefit, and environmental impact. Based on panel data from 2021 to 2023, descriptive statistics and Pearson correlation analysis are employed for empirical evaluation. The findings are as follows: ① Infrastructure scale has continuously expanded, with increasing mileage of highways, railways, and rail transit; ② Transport services show a “V-shaped” recovery, with passenger and freight volumes in 2023 rebounding significantly from the previous year; ③ Freight turnover is significantly positively correlated with total social logistics volume (r = 0.999, p < 0.05), revealing that the logistics industry still relies on an extensive development model of ”volume for value“ and economies of scale have not been fully realized; ④ Environmental impact is generally controllable, with vegetation area increasing year by year, though acoustic environment quality fluctuates. The study indicates that the transportation corridor of the Wuhan Metropolitan Area exhibits a structural characteristic of “infrastructure first, efficiency lag”. Service capacity improvement should be promoted from three levels: functional integration, network integration, and operational integration, driving the logistics industry to transform from scale expansion to efficiency-driven growth.
