Note: All variables are defined in first differences (D) of the
logarithm (L). GDP = gross domestic product; PGAS = gasoline price; TRAFFIC =
average daily traffic volume; TOLL1 = low toll elasticity group; TOLL2 =
low-medium toll elasticity group, TOLL3 = medium-high toll elasticity group;
TOLL4 = high toll elasticity group; D(Z1) to D(Z28) = first differences of
the dummy variables to account for changes in the road network.
