A: Longer Heavier Vehicles

Explore methods to minimize environmental costs, emissions, and waste while maximizing efficiency and reliability in transportation systems. Analyze the impact of longer, heavier vehicles on infrastructure and pavement design. Investigate the adoption of Performance Based Standards for longer semi-trailers and more efficient combinations. Stay updated on regulatory changes and institutional dynamics influencing transport logistics.

Presentation Transcript

  1. A: Longer Heavier Vehicles Q: Environmental costs (minimise) Emissions, Pollution, Waste ... Q: Track costs (balance) Pavement design / axle loads, tyre scrub ... Infrastructure: Bridge design / imposed load, Curves / turning circle ... Q: Economics (maximise) Efficiency; Reliability; ... Solution - Performance Based Standards (optimise) Longer semi-trailers More efficient combinations

  2. 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
