  • Publication number: 20210373575
    Abstract: A vehicle control system and method forecast an upcoming intersection area of projected paths of a first vehicle system and a second vehicle system based on current movements of the first vehicle system and the second vehicle system. A reach distance of the first vehicle system is calculated as a distance from a leading edge of the first vehicle system to the intersection area. A difference between the reach distance of the first vehicle system and a designated gap distance with the designated gap distance are compared. The speed of the first vehicle system is automatically reduced responsive to the difference being no smaller than the designated gap distance and/or the first vehicle system is stopped responsive to the difference being smaller than the designated gap distance.
