To be honest, alternatives to cars is the solution to most issues that have to do with roads in cities. Public transit handles thousands of times the capacity possible via cars. A single bus when things are slow still is more than a dozen times more effecient at using road space, not to mention all the costs involved, including gas, insurance, road maintenance, etc. During rush hour, a single bus can do the same work a hundred cars easy.

Not to mention trains and street cars, as well as bikes and just plain being able to walk around by just having functional side walks that don't get blocked off at the smallest little thing.
