DePaul University professor and transportation expert Joe Schwieterman said Chicago needs to take a look at what New York is doing with congestion pricing.

New York became the first place in the US to implement the surcharge on driving, following the example of a few international metro areas.

Preliminary traffic data is giving promising if occasionally mixed signals for the early days of congestion pricing’s impact on Manhattan’s busiest streets, with travel times down at Hudson River crossings but speeds within the zone slightly slower at key times of day year over year.
