(名詞) 不完全苜蓿型交流道。這個字是 partial cloverleaf interchange 的簡寫。
The Ontario Ministry of Transportation designed a modification to the original cloverleaf to address its shortcomings for the 400-series highways. The redesign creates more room for acceleration and deceleration and avoids the notoriously dangerous weaving lane. The Parclo has been embraced throughout the world as one of the most popular freeway-to-arterial interchange designs.
