{"title":"A Multi-Target Urban Transportation Structure Model under the Optimal\u0000 Capacity Limitation of Road Networks","authors":"Jinwei Zhang, Jianping Gao","doi":"10.4271/13-06-01-0003","DOIUrl":"https://doi.org/10.4271/13-06-01-0003","url":null,"abstract":"The construction of urban transportation infrastructures on the supply side is\u0000 severely limited due to the extensive development of central urban land.\u0000 Therefore, optimizing the traffic structure with limited resources is\u0000 particularly important. The work used the optimum capacity of the road network\u0000 as one of the constraints. Multi-objective linear programming was used to\u0000 establish the traffic structure model. The total travel volume, energy\u0000 consumption, travel quality, and social cost were selected as the optimization\u0000 objectives of the urban transportation structure. The influencing factors of\u0000 infrastructure capacity (e.g., total travel demand, optimal capacity of road\u0000 network, slow traffic capacity, and parking lot capacity) were selected as the\u0000 constraint conditions in optimizing urban transportation structure. The\u0000 objective was to develop an optimization model considering the constraints of\u0000 urban infrastructure. Finally, the optimal traffic structure was compared with\u0000 the actual travel structure using the actual case of Yuexiu District, Guangzhou,\u0000 China. Suggestions were provided for optimization.","PeriodicalId":181105,"journal":{"name":"SAE International Journal of Sustainable Transportation, Energy, Environment, & Policy","volume":"4 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141919968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
