More space for bikers and pedestrians walking
Saying this as someone who goes to Pittsburgh alot for business and doesn't live here, but one thing I've noticed is that there isn't enough room for cars, people on bikes and then also pedestrians. This creates a lot of congestion, at least from my experience. Now, I know this is an issue in all major cities, but just something I have noticed and can possibly be improved upon. I imagine this would create a lot less hassle for both residents and visitors.
