摘要：AbstractIn order to analyze and optimize urban cycling network planning, this paper classifies travel purpose into four types: relaxing, shopping, commuting and interchanging. The characteristic of each purpose is discussed, and an accessibility matrix is built to research the cycling possibility between each travel purpose. An algorithm based on kruskal method is introduced to construct cycling network. Taking Hanzhong, China as an example, the cycling network model and the practical cycling network of touring and outdoor sporting are constructed by this algorithm. The example shows that this algorithm is different from traditional gridding network planning, largely close to the psychology of cyclists and is easier to be accepted.
