[Purposes] Driven by the dual demands of the Healthy China strategy and the need for sustainable urban development, health factors are reshaping the slow-traffic transportation network system of modern cities. In response to the current lack of health attribute evaluation in the assessment of bicycle lane networks, this study aims to construct a health suitability evaluation system for bicycle lanes to achieve quantitative evaluation of the health attributes of the network. [Methods] Starting from physical activity, air pollution exposure, and cycling safety, this paper extracts three evaluation dimensions: network structure, lane safety, and independence, and constructs an evaluation system covering six quantitative indicators such as the degree of physical isolation, proximity to main roads, and non-linear coefficient. To address the issues of large differences in the dimensions of evaluation indicators and the difficulty in determining weights, the CRITIC (Criteria Importance Through Intercriteria Correlation) weighting method is introduced for hierarchical weighting. The comprehensive evaluation results of the study area are obtained by solving the weights at each level. Taking the urban area of Xi"an as an example, this study combines GIS spatial analysis technology to complete an empirical study.[Findings] The results show that the independence dimension of bicycle lanes in the study area has the highest weight; the non-linear coefficient and proximity to main roads have the most significant impact on cycling health; the final weighted evaluation values of Yanta District and Weiyang District are the best. [Conclusions]Based on the evaluation results, in future transportation planning, the core measures to improve the health attributes of bicycle lanes in the urban area of Xi"an include reducing the intersection and overlap of bicycle lanes with other roads, micro-renovation of roads to connect network nodes, and improving the isolation measures of bicycle lanes.
