A transport vehicle ( 1 ) comprising: —a heat engine ( 8 ) operable at a number of revolutions varying between a minimum number and a maximum number; —an adjusting device ( 52 ) configured to adjust an infeed flow of air-fuel mixture to the heat engine ( 8 ); —at least one on-board memory unit ( 61 ) in which an acoustic emission map ( 70 ) of the transport vehicle ( 1 ) is stored, wherein for each data pair comprising a first data item correlated to an operating condition of the adjusting device ( 52 ) and a second data item correlated to the number of engine revolutions, the acoustic emission map ( 70 ) associates, as a function of the first data item and as a function of the second data item, a third data item correlated to an acoustic emission measurement by at least one acoustic sensor (S 1 ) external to the transport vehicle ( 1 ) and arranged at a separation distance from the transport vehicle ( 1 ).

A rideable saddle vehicle including: a taillight arranged on a rear-carriage of the vehicle, the taillight being adapted to emit a light beam; a rear fender of a rear wheel connected to an unsprung mass portion of the rear-carriage, the rear fender having a front edge and a rear edge; a detection unit arranged on the rear-carriage and configured to detect the presence of other vehicles in a zone behind the vehicle, where the detection unit, in a side view of the rideable saddle vehicle, is arranged below the taillight, above the rear edge of the rear fender, behind the front edge of the rear fender and in front of the rear edge of the rear fender.
