Most people choose to use swinging doors over revolving doors when given the option.
My first sign was crude, but prompted 58% of people to use revolving doors.
My second sign was directional but small, and prompted 53% of people to use revolving doors.
My third and last sign was two feet wide and a food tall, and prompted 71% of people to use revolving doors.
I created a Revolving Door Toolkit that was purposely simple so that others could quickly modify and install them outside their revolving doors. Nearly 1,100 people have downloaded the toolkit.
