Uber and competitor Lyft had promised for years to relieve the world of traffic jams. A study has just been released that suggests that might actually be possible.

Carpool services like Lyft Line and UberPool could lower the total number of vehicles using the road by as much as 75% indicates findings released this week by the Computer Science and Artificial Intelligence Laboratory at MIT.

That means as carpool options that are app based become more popular, they will help make the clogged roadways around the country easier to drive. However, that means more commuter sharing rides with strangers and that could be problematic at times.

By transporting two, three or more people at one time instead of one person, fewer trips are needed over a lesser time frame with the ability to make the same money, said Daniela Rus a professor at MIT who led this study.

The findings of the study are based upon a algorithm developed by Rus’ group of students at MIT that found over 3,000 cars with a passenger load of 4 people could replace the close to 14,000 New York City taxis.

In addition, travelers could make this change with little inconvenience, as the average wait time would be 2.7 minutes.

This new study could help to legitimize the push by Uber and Lyft toward their shared rides where more than one passenger that is traveling in the same direction is matched into the same vehicle.

Both of the companies have been encouraging riders to use their carpooling services, which are quite new. The carpooling rides are less than those that are individual.

For example, Uber expanded its UberPool in March in a number of different cities around the country.

In cities where UberPool is now available, customers of the company choose the option for carpooling for 20% of their trips, shows data released by the company.

During the first seven months of this year, Uber said that if its riders had driven by themselves rather than sharing rides, they would travel 312 million additional miles and use over 6 million more gallons of gas, while emitting carbon dioxide levels exceeding 55 metric tons.

Lyft said its Lyft Line service was becoming increasingly more popular for its clients and would play a big part in helping the company build a world with less traffic and more importantly less pollution.
