The Autoridad Reguladora de los Servicios Públicos has approved an average of a 3.94 percent increase in the nation’s bus fares. Some fares did not change. The largest increase was a bit more than 7 percent.
The formula the agency used involves salaries, fuel costs, repairs, maintenance, administration and the amount of the last fixing of fares in February 2010. Operators of 187 routes received no increase because they did not submit all the needed documents, the agency said.
