Bike Roundabout Simulation: Right-of-Way and Lanes
A chalk roundabout with four entrances, crosswalks and yield signs is drawn on the blacktop, and students ride bikes and walk through it following right-of-way rules. It applies traffic safety to urban cycling and decision-making in traffic.
How to play
- Draw a chalk roundabout about 12 m (40 ft) across with a cone center island, four 15 m (50 ft) entry streets, crosswalks and cardstock yield signs.
- Take 4 minutes to cover the key rules: yield to traffic already in the circle, signal your exit, take the lane confidently and respect pedestrians.
- Split the class: 15 riders, 6 pedestrians using the crosswalks, and 4 observers, one per entrance, with an error checklist.
- Each rider gets a card showing their exit (first, second, third) and rides for 5 minutes entering from different streets.
- Rotate roles every 5 minutes so everyone is a rider, pedestrian and observer (15 minutes total).
- Close with 3 minutes where observers share the most common violations.
Rules
- Ride at walking pace; no passing inside the roundabout.
- Entering riders yield to those already in the circle.
- Pedestrians in the crosswalk always have the right-of-way.
- Helmets stay buckled for the whole activity.
Variations
Easier
Do the first round walking the bike to learn the layout.
Standard
A four-way roundabout with pedestrians and exit cards.
Harder
Add a student-controlled traffic light at one entrance and a protected bike lane.
Adaptations
- Limited mobility: take part in a wheelchair as a pedestrian or vehicle, or as an observer with the checklist.
- Visual impairment: ride with a partner on a tandem or walk as a guided pedestrian with verbal cues.
- Little bike experience: start as a pedestrian only, then ride when fewer bikes are in the circle.
Learning goals
- Apply right-of-way rules at a roundabout as a cyclist.
- Signal exit maneuvers early.
- Value safe sharing of city streets between cyclists and pedestrians.
Equipment for a class of 25
- bikes: 15
- helmets: 15
- cones: 16
- sidewalk chalk: 6
- cardstock sheets: 8
Teacher tip
The usual mistake is exiting without signaling or from the inside lane; stand at the busiest exit. Cap it at 8 bikes in the circle at once if space is tight.
