You would probably do better with a hand-held microphone with a cardioid pickup pattern. This focuses the mic’s ability to pick up sound directly in front and pretty much eliminates sound from the sides and rear of the mic.
A lavaliere mic will tend to pick up ambient sound from 360 degrees and while it might be o.k. for you when you’re talking it won’t do much for someone you are interviewing.
The trick will be to keep the mic as close to your mouth as possible to reduce the street sounds and the music background.
