The solution is to block the street off from cars. I don't get why every street need to have two-way car traffic. It can even lead to more congestion when there's more roads and intersections. Here someone will always cry "it will kill the businesses on that street", but then the opposite happens. It's a more quiet street, it's walkable, can sit outside and drink a coffee etc.
