As they expected, the researchers determined that the $9 charge has sped up vehicle journeys into Manhattan, nudging some people who would otherwise drive at peak times to instead ride transit, drive earlier or later, or forgo the trip entirely. Because traffic thinned, those still opting to enter Manhattan by car saved roughly 83,000 hours per week, averaging around three minutes per journey, according to the NBER paper.
But drivers who never ventured into the toll zone also saved time: As a group, this cohort, including those traveling within Bergen County or from the Bronx to Brooklyn, racked up savings exceeding 461,000 hours per week. An average journey became just eight seconds faster, but because there were over 100 times more of them than Manhattan-bound trips, their aggregated savings were more than five times greater.
