This study focuses on the cold chain distribution path by considering road traffic congestion with transportation, real-time vehicle delivery speeds, and multiple-vehicle conditions. Therefore, a vehicle routing optimization model has been established with the objectives of minimizing costs, reducing carbon emissions, and maintaining cargo freshness, and a multi-objective hybrid genetic algorithm has been developed in combination with large neighborhood search (LNSNSGA-III) for leveraging strong local search capabilities, optimizing delivery routes, and enhancing delivery efficiency. Moreover, by reasonably adjusting departure times, product freshness can be effectively enhanced. The vehicle combination strategy performs well across multiple indicators, particularly the three-type vehicle strategy. The results show that costs and carbon emissions are influenced by environmental and refrigeration temperature factors, providing a theoretical basis for cold chain management. This study highlights the harmonious optimization of cold chain coordination, balancing multiple constraints, ensuring efficient logistic system operation, and maintaining equilibrium across all dimensions, all of which reflect the concept of symmetry. In practice, these research findings can be applied to urban traffic management, delivery optimization, and cold chain logistics control to improve delivery efficiency, minimize operational costs, reduce carbon emissions, and enhance corporate competitiveness and customer satisfaction. Future research should focus on integrating complex traffic and real-time data to enhance algorithm adaptability and explore customized delivery strategies, thereby achieving more efficient and environmentally friendly logistics solutions.<\/jats:p>","DOI":"10.3390\/sym17010089","type":"journal-article","created":{"date-parts":[[2025,1,8]],"date-time":"2025-01-08T09:30:45Z","timestamp":1736328645000},"page":"89","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Optimization of Multi-Vehicle Cold Chain Logistics Distribution Paths Considering Traffic Congestion"],"prefix":"10.3390","volume":"17","author":[{"given":"Zhijiang","family":"Lu","sequence":"first","affiliation":[{"name":"School of Management, Harbin University of Commerce, Harbin 150006, China"}]},{"given":"Kai","family":"Wu","sequence":"additional","affiliation":[{"name":"School of Management, Harbin University of Commerce, Harbin 150006, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8303-4596","authenticated-orcid":false,"given":"E","family":"Bai","sequence":"additional","affiliation":[{"name":"School of Finance, Southwestern University of Finance and Economics, Chengdu 611130, China"}]},{"given":"Zhengning","family":"Li","sequence":"additional","affiliation":[{"name":"School of Management, Harbin University of Commerce, Harbin 150006, China"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,8]]},"reference":[{"key":"ref_1","first-page":"446","article-title":"The Economics of Traffic Congestion","volume":"82","author":"Arnott","year":"1994","journal-title":"Am.
