Teams model how guests flow through a theme-park queue, calculating wait times and testing a redesign that keeps lines moving without cutting ride capacity.

Quick Start

Digital downloads only.

$0 to buy. Printing noted separately.

Student time: one class period, one day.

Teacher prep / build-ahead: separate from student time.

Scale it

The default plan is one class period on a single day.

Scale back: Fit it into a shorter period, use fewer effects, or run a demo instead of a build.

Scale up: Add one extra effect, or spread the share-out across another day.

Setup

Print or hand-copy the essential prompt for Roller-Coaster Queue Laboratory, then set out only paper, pencils, and the common or recycled items needed for one test. Use a tabletop representation whenever the original version mentions a room, specialized device, or digital tool; the learning comes from the decisions and evidence, not elaborate scenery.

Activity

  1. Review the ride's capacity per cycle and predict the average wait time for a given guest arrival rate.
  2. Lay out a queue path on poster board and move token guests through it to model the wait.
  3. Time the simulated wait, find it's longer than predicted once arrivals spike, and redesign the queue path or add a switchback to fix it.
  4. Present the improved wait-time data to a park-operations audience, explaining the redesign.

Done when: The group has completed Roller-Coaster Queue Laboratory when it can present the improved wait-time data to a park-operations audience, explaining the redesign and point to the observation, measurement, comparison, or trial that supports its conclusion.

Materials

poster board, small figures or tokens as guests, stopwatch, string for queue paths, markers; Decision matrix template; extra poster boards

Steps

  1. Review the ride's capacity per cycle and predict the average wait time for a given guest arrival rate.
  2. Write criteria (average wait under 15 simulated minutes, ride never runs empty) and constraints (fits on one poster board, wheelchair-accessible path width, same ride capacity, must have shade spots).
  3. Design at least three competing queue layouts, such as a single line, a switchback, and a split fast lane, on separate poster boards.
  4. Run each layout with the same arrival schedule card, including a spike, moving token guests and timing each guest's wait. Record data in a table.
  5. Calculate average and longest wait for each layout and graph the results.
  6. Score each layout in a decision matrix against the criteria and constraints, using the data, and choose the best one.
  7. Present the winning layout and its wait-time data to a park-operations audience, explaining the matrix scores.
