Traditional research methods suffer from issues such as privacy risks, coarse modeling, and limitations from single data formats, labeling difficulties, and coverage gaps. This study proposes a refined semantic trajectory construction method that integrates multi-source data (e.g., mobile signaling data, maps and weather conditions), known as the Campus Transportation Semantic Trajectories Space (CTSTSpace) framework. It enables the precise identification of semantic origin\u2013destination points from dynamic personnel trajectories, quantifies service performance through real-time road network mapping, and models multidimensional perturbations, achieving full campus coverage without complex labeling while ensuring robust privacy protection. Under clear weather conditions, the analysis demonstrates accurate recognition of travel behavior patterns (dwelling, aggregation, mobility, and congestion) that synchronize with class schedules, where vehicle speeds drop by over 50% during peak hours. Under rainy weather perturbations, it captured demand shifts (e.g., peak hour offsets of 30\u201360 min and a 6.8\u20139.2% reduction in long-distance dining trips) and speed reductions (52.15\u201373.74%). This approach provides critical insights for resilient smart campus traffic management.<\/jats:p>","DOI":"10.3390\/ijgi15030127","type":"journal-article","created":{"date-parts":[[2026,3,16]],"date-time":"2026-03-16T08:41:26Z","timestamp":1773650486000},"page":"127","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["CTSTSpace: A Framework for Behavior Pattern Recognition and Perturbation Analysis Based on Campus Traffic Semantic Trajectories"],"prefix":"10.3390","volume":"15","author":[{"given":"Lin","family":"Lin","sequence":"first","affiliation":[{"name":"School of Water Conservancy and Transportation, Zhengzhou University, Zhengzhou 450001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mengjie","family":"Jin","sequence":"additional","affiliation":[{"name":"School of Geo-Science and Technology, Zhengzhou University, Zhengzhou 450001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2131-3909","authenticated-orcid":false,"given":"Zhiju","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Civil Engineering, Zhengzhou University, Zhengzhou 450001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenhao","family":"Men","sequence":"additional","affiliation":[{"name":"School of Water Conservancy and Transportation, Zhengzhou University, Zhengzhou 450001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yefei","family":"Shi","sequence":"additional","affiliation":[{"name":"School of Geo-Science and Technology, Zhengzhou University, Zhengzhou 450001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8684-7015","authenticated-orcid":false,"given":"Guoqing","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Computer Science and Artificial Intelligence, Zhengzhou University, Zhengzhou 450001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,3,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"14","DOI":"10.1016\/j.jtrangeo.2024.103943","article-title":"Routes with roots: Pedestrian route choices and sense of place of an urban university community","volume":"118","author":"Chan","year":"2024","journal-title":"J.
