Transportation experts say it could take several weeks or even months to learn the true impact of congestion pricing.

But commuters throughout the state say they're already seeing the difference.

Many told us trains are packed and the seats are filled.

The frigid start to the week isn't helping.

There have been plenty of service disruptions to frustrate even the most seasoned mass transit rider.

Begging the question as to whether New Jersey's public transportation system is going to be able to keep up.

Senior correspondent Brenda Flanagan reports.

Much more crowded trains and busses.

The trains are packed.

There's no seating really, at all.

Frank Barker catches an NJ transit train in Ridgewood and thinks congestion pricing is definitely had an impact on his commute through Hoboken into downtown New York City.

He's not the only one traveling back home during rush hour is crowded.

Stand up loud.

Crowded like a Kansas City on social media.

Riders have posted photos showing crammed cars.

Never seen so many people on the train, one commented everyone looks pissed.

First Monday in the congestion pricing era in NYC.

Not good.

From Steve and Roselle Park, standing room only and packed in tightly.

Thumbs up NJ Transit.

Way to go!

Extreme cold and some snow did impact mass transit, and four days of data don't make a trend, but advocates say something's happening.

At least anecdotally.

It does appear that more people are taking New Jersey Transit, and they are right to be concerned about new Jersey transit service.

But New Jersey Transit's problems existed before congestion pricing.

People are actually ditching their cars, their personal vehicles and getting on the trains.

And people are noticing the trains are a bit more crowded.

Which is the point of congestion pricing.

The MTA cited a spike in subway ridership.

It rose almost 13% in the city on Tuesday, compared to a year ago, but ridership rose, too.

As for street traffic, it's not moving appreciably faster.

But I've noticed in the streets I'm seeing less cars.

I did see that over this last week in the city does seem a little quieter, a little less traffic, and it's only a few days, and I don't want to draw conclusions yet, but I've not gotten reports that NJ transit trains, busses, Path trains are overflowing.

Governor Murphy said yesterday New Jersey is still reviewing all legal options in its ongoing court battle against congestion pricing.

And we're reasonable people.

What's a reasonable number north of what I'm already paying?

If we get mitigation back, if indeed we get actual real dollars into projects that matter for Jersey commuters, his take on the significant drop in traffic at Hudson River crossings this week.

People are working from home.

We're not sure, because we need the data, but I think if I'm New York, it's a be careful what you wish for reality.

And that is people are saying, you know what?

We're going to work from New Jersey.

Governor Murphy, spent all of last year suing New York, and he could have been using that time to beef up new Jersey transit and prioritize helping expand service.

For New Jersey riders, it's hard to tell whether or not new Jersey transit is ready for this influx in commuters.

And that's part of the problem is that New Jersey transit tends to be unreliable.

So how will NJ Transit handle a shift in commuters to its trains and busses?

The agency says it hasn't seen a notable increase in riders this week, but added we will continue to monitor for any changes in commuting patterns.

It's also important to note that prior to congestion pricing, many NJ Transit trains and busses during peak periods were already at or above pre-pandemic levels.

Conductor Chris Marano agrees.

Our trains already have been like, really, really, packed like we've had ridership has gone up, definitely, especially on the evening rush hour trains going out west.

I would love to hear from New Jersey leaders on how they're thinking about making sure the transit system stays reliable and trustworthy for the citizens, for the riders in New Jersey, advocates say adding more trains and more service takes more money.

While a new corporate tax did save NJ Transit from $1 billion fiscal cliff, and the agency significantly raised fares, it's still struggling.

After enduring two so-called summers of hell, riders are hoping NJ transit will adapt to congestion pricing.
