How do autonomous vehicles contribute to reducing traffic congestion?

Instruction: Discuss the mechanisms through which autonomous vehicles can alleviate traffic congestion.

Context: This question evaluates the candidate's insight into the potential of autonomous vehicles to improve traffic flow and reduce congestion through coordinated driving patterns.

Updated

Example Answer

Autonomous vehicles could improve some traffic behaviors, but congestion reduction is not guaranteed. Coordinated speed control or routing may help under suitable conditions, while mixed traffic, extra demand and empty repositioning trips can offset gains. I would compare service designs using total vehicle miles, occupancy, travel time and effects on other road users. Tighter spacing is not a free capacity gain: it still needs justified safety margins and a validated operating domain.

Make it your own

Illustrative comparison: private vehicle trips versus a shared service, including passenger trips, pickup journeys and empty repositioning. Evaluate the complete network, not only occupied-trip time.

Why this works

Efficiency per vehicle differs from efficiency for the transport network. Follow-up: how could a faster trip encourage enough additional travel to increase congestion?
