No, I go for walks alone in my street all the time. As several people mentioned at night, I don't really like doing that. It doesn't scare me, but I worry about seeming creepy to the cars that pass by, or if anyone happened to see me. So I try to avoid it, but in the winter when it gets dark early it happens sometimes.
I rarely see anyone out walking at night here, but a few times I've seen a guy walking his dog at night.
