哪位大神帮我看看这英语句子对不对

Question

The traffic in London is convenient，as which Beijing's is the same.

Answer 1

不好。建议改为：
Driving is easy in London, just like that in Beijing.
或: The traffic in London is as light as that in Beijing.
traffic 和 convenient 语义似乎逻辑不协调。句子也有语法问题：as which Beijing's is the same 语法上说不通。

或者：
It's convenient to drive around London. The same is said about Beijing.

供参考。(不过我很怀疑这句话的真实性。）

Answer 2

The transportation in London is as convenient as in Beijing.

Answer 3

the traffic in london is the same as which in beijing.追问

那么我这句不行咯？

追答

我觉得也行，不过感觉有点儿别扭……
我认为the traffic in london is the same convenient as which in beijing .更顺
你说是吧!

Answer 4

伦敦的交通便利，和北京的是一样的。追问

嗯，我这句语法有没有什么错误

追答

我只能给你这样翻译，如果你问我语法错误的话。我真忘了。 你想表达什么意思？
