TOYOTA Sienna Incident

The May autonomous vehicle was travelling in an autonomous vehicle (AV) only lane, on [XXX], approaching the intersection at [XXX] A vehicle travelling to the left of the May shuttle in the non-AV lane attempted to perform a right hand turn across the May vehicles path and collided with the May AV. The primary factor that led to this collision was human error on the part of the other vehicle that was required to yield to through traffic in the AV lane but did not. Right turns across a straight lane are uncommon, and drivers are typically not used to them, however there is a metal street sign that instructs other traffic to yield to the vehicles in the AV lane. There were no autonomy faults or errors which led to this incident. Additionally, there is a second traffic light at this intersection that warns public drivers to yield to the AV shuttle. This light was not operating as it should during this incident. We are working with our partner to maintain the operation of this light and have implemented a mitigation policy of daily inspections of this light and implementing an AVO in service if this light is not functioning.
