Atlanta on Sept. 14 became the latest city to put sensors needed for autonomous driving to the test. The trial, part of the city’s SmartCity initiative, tested more than 100 sensors installed along the city’s North Ave. The corridor has a higher-than-average crash rate compared to similar roads in the state, making safety improvement one of the primary long-term objectives.

Designing roads and other infrastructure with autonomous vehicles in mind–by including sensors, for instance–will be a key step in advancing the technology and maximizing its benefits, says ATI21’s Paul Brubaker. Read AP’s summary of the Atlanta trials for more.
