由於內文提到的高雄點蠻多的
所以轉來高雄板讓大家討論

標題: [問題] 快/慢車分隔島是否成為交通毒瘤?

台灣很多地方設分隔島來區分汽機車
就這個問題我列出幾個會產生的問題
以高雄民族路及博愛路為例
1.快車道禁止右轉,要右轉的汽車要提前駛入右側慢車道
又因駛入後汽車車速降低
==>汽車後的機車產生回堵狀況,如果越多汽車駛入慢車道則越嚴重
==>汽車要切入慢車道要完全停車等到才可以駛入(需等候多時)
2.有些路口會設多時向號誌(即允許外側快車道右轉)
請參考:https://youtu.be/sRJhZ66704c
==>整個路口紅燈秒數總和大幅提高,降低車輛吞吐量
==>一個車道必定要等候多時
==>若紅綠燈沒規劃好,有很大的機會產生死亡交叉
(快車道右轉、慢車道直行)
3.有時候沒分隔島,有時候又有分隔島
甚至車道往前對就是分隔島
請參考街景圖:https://goo.gl/maps/mNRspqDvSe82
==>機車到底要騎上哪一條?左/右車道?還是騎上分隔島?
4.慢車道許多停車格、或是違停車輛
==>車道過於狹窄,行車危險
5.民族陸橋跨越建國路只限汽車行駛
而機車只能行駛機車道
然而這個機車道跨越鐵路後還要下橋在建國路等紅綠燈
==>不符合交通效益
如果機車不在建國路左右轉
照理來說機車應該要上跨建國路的車道才對
但目前礙於該車道禁行機車,只能靠交通局的作為
6.慢車道=機車+腳踏車+電動車一起騎上去
==>車速不一,而機車車速快很容易和真的慢車產生車禍

若還有更多會產生的問題,歡迎補充
本人樂意補充到本文裡面!
綜觀以上問題,個人的結論是:
快慢車道的分隔島的設計,完全是交通的混亂的主因
--
上述問題整理可得到明確的缺點所在
可以想像沒有分隔島可以減少不必要的交織
也能讓交通順暢許多
最近發生那麼多與汽機車分流的問題,新聞報導也報很多次
那為什麼政府都不願意積極處理呢?
我也想問各位鄉民們
你們對於快慢車分隔島要維持不變?還是全面拆除呢?
