Transit Utilization and Traffic Congestion: Is There a Connection?

Research finds no statistically significant evidence linking increases in transit utilization to reductions in congestion

Statistical analysis of the 74 largest urbanized areas in the U.S. over a 26-year period suggests that increasing transit utilization does not lead to a reduction in traffic congestion; nor does decreasing transit utilization lead to an increase in traffic congestion.
Policies designed to promote transit utilization can in certain instances increase traffic congestion—as appears to have been the case in Portland, Oregon.
Vehicle-miles traveled per freeway lane-mile is strongly correlated with traffic congestion: the more people drive relative to available freeway capacity, the worse congestion gets.
Data from New York and Los Angeles indicate that the most effective way to increase transit utilization is by reducing fares, as well as by improving basic, pre-existing service.
