摘　　要：随着交通量的持续增长,许多道路,特别是城市与区域间的主要交通干道,正面临严重的拥堵与交通安全隐患。许多旧有道路的设计标准与承载能力已无法满足现代交通的需求,导致频繁发生交通事故,且设施老化问题愈加严重,严重影响了出行的安全性与效率。因此,道路改扩建已成为解决交通问题、提升城市功能及促进经济发展的关键措施。合理的改扩建设计不仅能有效缓解当前的交通压力,还能够为未来交通需求的增长提供保障,从而推动社会的可持续发展。With the continuous growth of traffic volume,many roads,especially the main traffic arteries between cities and regions,are facing serious congestion and traffic safety hazards.The design standards and carrying capacity of many old roads can no longer meet the needs of modern transportation,resulting in frequent traffic accidents and increasingly serious problems of aging facilities,seriously affecting the safety and efficiency of travel.Therefore,road reconstruction and expansion have become key measures to solve traffic problems,enhance urban functions,and promote economic development.Reasonable renovation and expansion design can not only effectively alleviate current traffic pressure,but also provide guarantees for the growth of future transportation demand,thereby promoting sustainable development of society.
