Solution - Performance Based Standards (optimise) Longer semi-trailers More efficient combinations
Longer semi-trailers - background 1960 - Competitive systems: ISO Series 1 vs. palletised cargo Political:Operational:Technical bias (geographical/modal/economic) 1970 - Paradigm shift from ‘space’ to handling considerations Converging gateways : outer (handling/transport), inner (pallets) 1980 - ISO regulatory change - pallet compatible containers 2000 - EU new generation of ‘swap bodies’ Institutional asymmetries & UNCTAD/ISO rivalry? 2010/15 - Next Generation (EU or Worldwide?) EU road dominant : Import/Export ISO x2 x3 : Combined Transport? OSS - Open Source Software
