Improvement of the Tongxiao-Dajia Interchange of Provincial Expressway No.61

省道快速公路提供快速交通服務，並於相關地點設置交流道提供進出服務，而台61線西濱快速公路之交流道配置並非均為全套交流道，常以單側匝道進行配置，進而衍生相關問題，本研究以台61線通霄-大甲區段為例，進行相關問題探討，並就提出改善方式進行預期改善效益分析，以路網交通、交通安全以及事故救護派遣等面向進行探討，以瞭解交流道配置形式之影響及其改善成效。

Expressways provide a path for fast-moving traffic, and interchanges are set up at relevant locations to provide access and exit. However, not all interchanges on Provincial Expressway No.61(West Coast Expressway) are directional, often designed as partial interchanges, which leads to some traffic issues. This research took Provincial Expressway No.61 Tongxiao–Dajia section as an example to discuss related traffic issues, analyze the expected benefits of the improvement proposal, and discuss the aspects of traffic network, traffic safety, and accident rescue. To understand the impact of interchange configuration and its improvement effect.
