Good traffic without an offer is an indication of a price that is slightly high, but not over the top. When a property is very high, the market ignores it and you get no showings.
When buyers come to visit it and tell you that they are concerned about the corner, what they are saying is for this amount of $$, I don't want to be on a busy street. They believe they can spend the same, or near the same amount of money, and do better. The only way to compensate for a busy corner is price.
You must balance price and exposure. You are getting showings, so there doesn't seem to be much question about exposure. On the pricing side of the balance scale, you either add value to bring the proeprty up or decrease the price. In your case, you can't change the fact that you are on a busy corner, so you can only address it in the price. An example of where a homeowner could add value instead of lowering the price might be in staging, de-cluttering, repairs.
You need to price with the corner in mind. This way the buyer will say, "It's on a busy street, but it has so much more than x property down the street. I'll live with the busy street." It was to be worth it to the buyer to accept the drawback of the corner.
