Signage Strategies

Books on signage strategies for events and locations, as well as official guidance from various Departments of Transportation. I wanted to know what kinds of signs are helpful, unhelpful, and what the appropriate amount of signage is.

The recurring rule for “how much signage?”

There really isn't a good formula such as “one sign per 500 feet” or “20 signs per 1,000 attendees.” The better unit of measurement is the decision point.

A solid event/location system usually looks like:

arrival → orientation → advance direction → decision-point direction → reassurance → destination identification

So, for example:

Parking → Event Entrance → Registration → Hall A/B choice → “Hall A →” → “Hall A”

Helpful signs are those that answer a question exactly when the visitor needs the answer: Am I in the right place? Which direction now? Am I still going the right way? Have I arrived?

Unhelpful signage is typically duplicated information with no navigational purpose, giant directories presented at every intersection, long sentences, inconsistent destination names, signs placed after the turn, signs obscured by crowds, and decorative/sponsor signage that visually competes with operational guidance. FHWA's terminology is useful here: you want enough repeated directional guidance to maintain confidence, while avoiding sign clutter. MUTCD

For a temporary event, I would generally inventory six classes separately: arrival/identity, orientation/maps, directional, reassurance/confirmation, destination identification, and regulatory/safety/accessibility. Doing that tends to reveal both missing signs and unnecessary duplicates much more clearly than simply counting the total number of signs.
