Queue Management Selection
ITE provides guidance on the applicability of the aforementioned queue management strategies depending upon the clear storage distance measurement, as shown in the table below. Generally speaking, the closer a crossing is to a signalized intersection, the more likely that a pre-signal installation will be the most appropriate design choice. When the grade crossing is located further away from the intersection, a queue cutter may be deemed more fitting. However, for CSD measurements between 200’ and 400’, designers should rely on engineering judgment, the Diagnostic Team and analyze the local traffic conditions and roadway features to determine which strategy would be more effective.
CSD | Queue Management |
|---|---|
≤ Design Vehicle Length to 200 feet | Pre-Signal |
200 feet to 400 feet |
|
> 400 feet | Actuated Queue Cutter |
