The formula that establishes how to increase the price of tolls in each year is provided for in Decree-Law no. 294/97 and establishes that the variation to be practiced in each year is based on the annual rate of inflation without housing in the Continent known until November 15, when the dealers must inform the Government of their price proposals.
In a quick estimate of the Consumer Price Index (CPI) published today, INE forecasts that the annual rate of inflation, excluding housing, in the Mainland will have been 0.98% in October, which should have a percentage of toll prices next year.
In 2018 motorway tolls increased 1.42%, after a rise of 0.84% in 2017 and 0.62% in 2016.
The legislation currently in force also defines that the toll rates should be updated in multiples of five cents, which implies rounding toll rates to the nearest five cents.
The final CPI data for the month of October will be published on November 13.
