Transmodel has been extended to take into account the alternative modes, in particular vehicle sharing, vehicle rental, vehicle pooling. This extension has been published as CEN TS 17413:2019. This part is currently being implemented as NeTEx-Part 5 (Alternative Modes API).
The conversion of CEN TS 17413:2019 into an EN is being planned (Transmodel -Part 10).
