At locations where the crossing has multiple signalized intersections near a crossing or is located between two signalized intersections as illustrated in Figure 3-4, the traffic signals should be interconnected and coordinated to reduce the potential for traffic to queue across the tracks. If geometrics and equipment constraints allow, both intersections should operate off the same traffic signal controller to ensure seamless coordination. During a preemption event, both signalized intersections shall allow track clearance green to allow vehicles to clear both the tracks and their respective downstream intersections. If the distance between the intersections is short, the traffic signals should operate to keep the roadway between the intersections clear during normal operations.

When filling out TxDOT Form 2304, TXDOT recommends to perform preemption calculations for each signalized intersection that will be interconnected to the crossing. The preemption request shall be for the highest calculated advance preemption time. Since both intersections will be interconnected to the crossing, the MTCD should be the same for each form as the railroad will base the clearance time on the largest MTCD.
