Free public transportation may not be the best solution to the traffic congestion since it can have huge financial implications on the city budget. If public transportation runs free, it could potentially cause a significant monetary problem. In the meanwhile, other solutions can be considered by governments; for instance, they can promote bicycle lanes and walking paths. In addition, local authorities can introduce congestion charges, which can reduce traffic jams. As a result, these measures can encourage people to use buses, trains, and trams more. Consequently, free public transportation may not a viable solution.
