EVALUATION OF DELAY MODELS FOR MOTOR VEHICLES AT LIGHT RAIL CROSSINGS

The application of theoretically and empirically based delay equations, developed for isolated traffic signal operation, to the problem of isolated at-grade light rail crossings was evaluated. Data were collected at 24 crossings of five transit authorities to validate a model for average stopped delay from among 21 candidates. The successively validated model was the pretimed delay equation from the 1985 Highway Capacity Manual. When a background cycle is imposed by traffic signals controlling the crossing, the delay model developed by Allsop was found to be suitable when applied with its lower limit parameters.
