Greater adoption of CAV may result in long-term benefits but mid-term fluctuations for costs and congestion, according to predictive model.

A simulation model evaluated the potential impacts of increasing connected and automated vehicle (CAV) market penetration.


Background (Show)

Lesson Learned

Agencies seeking to promote CAV adoption should anticipate that negative results could arise during the process of transitioning from manual to automatic vehicles. The increase in congestion is expected to be completely outweighed by the point of 70-80 percent CAV adoption, for a significant overall increase in efficiency.

On the whole, the mixed results from the analysis indicate that CAV adoption--which is likely to take a significant amount of time--will not be a unilateral benefit to cities, and in fact many of the positive changes will be mostly or completely offset by changes in traveler behavior.
