Traffic Light Mapping, Localization, and State Detection for Autonomous Vehicles

December 2020

tl;dr: Mapping and online detection of TFL.

Overall impression

Traffic light state perception is the key.

Even in non-autonomous vehicles, traffic light state detection would be beneficial alerting inattentive drivers to changing light status and making intersections safer. –> TLA

The key to safe operation is the ability to handle common failure cases, such as FP or transient occlusion for camera based TFL perception.
