Question

how would the self driving cars (smart cars) react to a temporary signage (construction) traffic cops,or ambulance with sirens trying to pass them, by it self without human helps, and do you think we would see this in the future?

Answer 1

its radar, liDAR, and camera sensors are always scanning 360 degrees around the vehicle, and also There are weather proof microphones available, and the processing requirements for siren recognition is a well bounded problem. For now, we will need to rely on the driver being able to respond and take over control of the vehicle.

The long term solution to this problem will be vehicle-to-vehicle (V2V) and vehicle-to-everything (V2X) radio connections. These radio links provide a valuable adjunct to the other sensors. With V2X, the autonomous vehicles communicate to each other providing live information that can range beyond the range of the other sensors. With V2X, other vehicles with a better view could warn all cars that an emergency vehicle was coming. It would be best if the emergency vehicles could transmit information to all cars in the local area signally them to hold position. A V2X system might also work in a similar way with sensors on local structures, like light poles, even pedestrians, that could transmit the emergency warnings.
