現在是暑假
暑假的傍晚往台北方向
這個現像特別明顯
就是說出了隧道才變快。
為什麼呢?
因為進隧道時大家車距是近的,
然後隨著速度提高,車距也拉大
如果說都拉開剛好的車距就算了,是穩定提速
只要有ㄧ台拉得過長,後面就要等比較久才能提速度。
那麼為什麼出了隧道會突然緩解速度呢?
因為可以變換車道
也就是說板上最討厭的飆仔與鑽車仔
他們盡早脫離過慢或車距過長的車
消化了車流
所以他們才是抒解塞車的人
至於板上愛說的煞車連鎖反應
那是個瞎扯蛋
因為跟實際狀況不符
只有同時每台高速
又過於密集才有每台都非煞車不可的狀況
實際上幾乎觀察不到這現像
引述《august64 (august64)》之銘言:
: 長年以來雪隧走過上百次每次剛進去車速都會很龜
: 常常只有20左右
: 但走個三四公里後會突然變快車速提升到五六十
: 這現象實在很不解雪隧從剛進去到三四公里這段路
: 中間並沒有交流道讓車子出去啊
: 為何車流要過三四公里後才會變快呢?
: 同樣一群車子到底是基於什麼原因
: 要進雪隧走了三四公里後才願意開始踩油門?
