David Sachs the reports on a new study by a Alejandro Henao, a PhD candidate at the University of Colorado that will be of interest to anyone tracking the impact of transportation network companies (TNCs) like Uber and Lyft on mode choice and congestion.

"Ride-sourcing companies like Uber and Lyft add tons of traffic to Denver and Boulder streets, and make the transportation system less efficient by cannibalizing transit, biking, and walking trips," according to Sachs's summary of the study.

The findings of Henao's study offer resistance to the predictions offered by a study by MIT's Computer Science and Artificial Intelligence Laboratory in January, which found carpool services operated by TNCs could reduce the number of vehicles on the road by 75 percent.

The debate will likely continue.
