Statistics Portugal releases the main statistical results on business in the transport and communications sectors in 1999. There were some changes from the previous years, namely: Transport by road - the results from two surveys that were previously separately published are now released simultaneously: Survey to Passenger Transport by Road in Heavy Vehicles (Portuguese acronym: ITRP) - 1999: similarly to previous years, the ITRP only focused on transport on own account, given that the file regarding transport for hire or reward was not made available by the competent authorities. Survey to Freight Transport by Road (Portuguese acronym: ITRM) - 1999: ITRM results comprise statistical returns in respect of the carriage of goods by road, by means of vehicles registered in Portugal, in compliance with the provisions of Council Regulation (EC) No 1172/98 of 25 May. Sea and coastal water transport - Information made available on the Autonomous Regions of Azores and Madeira was significantly reduced, either because it had not been made available in a timely manner, or because it showed some gaps when it was made available, which were not clarified in due time.
