The urban waterside area is an important component of the urban spatial structure. However, current research on this topic cannot comprehensively and accurately measure the integrated development of the urban waterside area because of its comprehensive value and the coordination topic of watersides’ equilibrium resulting from various elements in the physical space and the social system. Therefore, with an emphasis on urban synergy and balance, it is indispensable to establish a comprehensive quantitative index system to evaluate the integrated development of urban waterside areas. This research takes Shanghai, Guangzhou, Wuhan, and Ningbo as cases and evaluates urban waterside areas on aspects of socio-economic and physical spaces to construct an integrated development evaluation system. First, the distance that can be reached by public transit within 30 minutes from each city river’s shoreline is considered as the search scope. The socioeconomic indicators include the number of points of interest (PoIs) and population density based on location-based services (LBS) data, while physical space indicators include walking and vehicle traveling potential. Moreover, the analytic hierarchy process (AHP) is employed to calculate the weights of the above indicators. Finally, a qualitative evaluation model based on multi-source data for evaluating the integrated development of urban waterside areas is proposed. The results show that Ningbo and Guangzhou have maintained relatively high integrated grades, and the balance has developed more evenly. Among the four cities, the waterside’s integrated level of Wuhan is the lowest in each range, leading to its relatively large spatial diversity, weak accessibility, and low development intensity. This research not only contributes a more scientific way of defining isochrones based on Gaode API but also solves the long-lasting problems of limited labor costs, few research samples, and a short-covered timeline in urban evaluation, which support future refined urban design practices in the waterside area.
