Translation of Straßenverkehr

There is a small misunderstanding about the homework. I can do them, but they will be too confusing? I am trying to find the article from where I took the sentences in order to ease the task for all students.
I had never heard the phrase before. In America, there are also different idioms than here in England. It seems that the Americans say it differently than we do here in the United Kingdom.
I would also like to thank you for your interesting phone call on Friday 4 weeks ago. As you have proposed at that time, I will bring up a few ideas for possible cooperation in the future.
