The influence of in-vehicle speech warning timing on drivers collision avoidance performance at signalized intersections
In-vehicle RLR collision warning timing was tested in a driving simulator. The range of warning lead time is from 2.5s to 5.5s with 0.5s increment. Collision avoidance performances are highly affected by warning timings. Earlier warning leads to shorter reaction time and lower deceleration rate.
