At interconnected grade crossings, approaching motorists need to perceive and react to a multitude of messages and indications including the railroad warning devices, signing, striping, and the traffic signal, which are all within relatively close proximity. The design of interconnected crossings can be complex. Designers must respond to physical constraints on both the railroad and highway right-of-way that require various clearances while also ensuring that all traffic controls operate properly together. This chapter explores the various design elements that can be implemented to guide motorists through the grade crossing and the adjacent signalized intersection in a safe and efficient manner. The most appropriate design elements shall be determined by the Diagnostic Team as discussed in Chapter 2.
