<s>[INST] The next text is a question of a member of the European parliament:"The statistics annexed to the Commission's communication on the future development of the common transport policy show that, in 1990, the transport of goods within the Community could be broken down as follows:      -  rail: 15.4%;      -  road: 69.9%;      -  waterways: 9.2%,    and that the proportion of goods transported by road increased steadily from 50.6% in 1970 to 69.9% in 1990, while the proportion carried by rail declined from 27.8% to 15.4% over the same period.  This trend is probably due to the railways' slow and bureaucratic administrative procedures, which mean that goods take longer to arrive by rail than by road. The result is increased environmental pollution from toxic exhaust gases and, on certain days of the week, heavily congested motorways, with the ever-increasing number of heavy goods vehicles causing hold-ups and delays for other road-users.    Does the Commission:      1.  consider that it would be advisable to proceed as soon as possible with the harmonization of technical characteristics of road vehicles, particularly with regard to combined transport?      2.  intend to propose interoperability for high-speed trains with a view to modernizing and speeding up the transport of goods?      3.  consider that reducing the proportion of goods transported by road and promoting rail transport is a priority for the development of the common transport policy to ensure a sustainable transport system?"
