This model is a representation of a pair of bowling lanes. Since bowling lanes are long and are not usually able to be walked on, this model provides access to understand the relative dimensions and object locations on a bowling lane. There is usually a ball return stand located between a pair of lanes and this model show two lanes, the ball location, the foul line mark, the gutters, and the pins. Floor markings are included for partially sighted who may be able to see them on the lane.
This model shows the full length of the lane and ball and pin locations to scale. To the right of the lanes, are braille labels for the balls, approach, foul line and pins. There is a small cube in the upper right of the models to help with orientation for reading the model.
