I would suggest you also visit the house at night, before you buy and see what the noise is like. Park in the road and listen. Will you be able to stand the noise when you have the windows open in the summer? When you want to be in the garden?
Hedges (much better at filtering noise than walls) are a possibility, but they do take time to grow and thicken up.
