DESIGN OF GATE DELAY AND GATE INTERVAL TIME FOR FOUR-QUADRANT GATE SYSTEM AT RAILROAD-HIGHWAY GRADE CROSSINGS

A design methodology for gate delay and gate interval time for at-grade crossings utilizing four-quadrant gates is developed. The design approach is based on the concept of dilemma zones related to signal change intervals at signalized intersections. The design approach is validated based on data from six sites in Illinois on a proposed High Speed Rail corridor. Gate delay and gate interval times are determined which provide an optimal safe decision point to allow a driver to stop before the crossing or proceed through the crossing without becoming trapped by the exit gates.
