It is desirable that the intersection of highway and railroad be as level as possible from the standpoint of sight distance, rideability, and braking and acceleration distances. If a railroad crossing is located at the peak of a vertical curve on the highway, the curve should be adequately flat to avoid hanging-up of vehicles and of sufficient length to ensure an adequate view of the crossing consistent with the highway design or operating speed. Refer to TxDOT’s (Chapter 7, Section 1) and for additional information.
