The midpoint method calculates the average of the initial and final values. In this case, the initial value is 1 lane and the final value is 2 lanes. The average of 1 and 2 is 1.5 lanes. The percent change is calculated as (final value - initial value) / (initial value) * 100%. In this case, the percent change is (2 - 1) / 1 * 100% = 100%.
