An encrypted traffic signal device controller (TSDC) and an Electronic Variable Message Sign (EVMS) at intersection roadways and related traffic intersections where the invention system is installed at traffic light intersections which will be triggered at the red light sequence where vehicles/pedestrian/cyclists are stopped. After the traffic light turns red, the time delay of the red light will trigger an audio and visual public announcement which will be of assistance to the driver and enable the driver to pay attention to the announcement without being concerned about diverting the driver's attention from driving the vehicle since the vehicle is stopped at a red light and the driver can devote his attention to reading the information provided.
