data are for every half-hour, the time unit used in specifying the regression models for estimating the parameters. tolls currently in force were defined during the tender process for the highway construction and take into account the infrastructure capital cost. difference between the MIU optimum and the MR optimum, expressed as the percentage the former is of the latter.
