AC21 - New Technologies for Sustainable Transport
Business level (Australian Logistics Council 2002) Interoperability: The ability for partners to coordinate information and processes, especially across an electronic network Technical level (IS0 TC204 document N271 1999) Interoperability: The ability of systems to provide services to and accept services from other systems and to use the services so exchanged to enable them to operate effectively together Software level (Greenfield Software Factories 2004) Interoperability is a measure of how easy it is to compose the software of other systems. This is determined by how well the software exposes its functionality through programmatic interfaces and how much context must be maintained by the other systems to use those interfaces Interoperability defined Chris Skinner – Seminar, Institute of Transport & Logistics Studies

ISSUES FOR TRANSPORT - EFFICIENCY • Efficiency: • benefits / costs / risks; • costs per unit (km, pax, tonne); • costs per operating hour; other variable costs eg crew; • indirect costs (externalities); • ROI for fixed costs (cost/year) • Benefit ~ cost / hr; benefit (unit * km = UKT) Chris Skinner – Seminar, Institute of Transport & Logistics Studies
Freight transportation is really (product inventory | WIP | materials)while it is in transit AC21 - New Technologies for Sustainable Transport
Energy Consumption • Energy usage is increasing • Non-renewable energy resources are declining • Increasing emissions from energy consumption, including • Noxious emissions [Nox] • Greenhouse gases [GHG] • Transport share of energy consumption, which is f(increasing demand) Chris Skinner – Seminar, Institute of Transport & Logistics Studies
Emissions are a function of… • Emissions = function of • ( VKT, payload weight/volume, engine efficiency, fuel type, other factors…) • where • VKT = vehicle-kilometres travelled • Payload is either • Number of passengers; and/or • Tonnes of goods carried • Volume is either • f(weight, density); or • f(space per passenger, space for baggage, crew, access and egress etc) Chris Skinner – Seminar, Institute of Transport & Logistics Studies
Energy usage for transport – metrics • Measure – joules per transport unit: VKT, pax-km; tonne-km (UKT) • Efficiency – direct transport consumption, unproductive consumption • Additional concept of time taken for travel • Value of time saved/consumed for journey • Other key performance indicators [KPI] are needed Chris Skinner – Seminar, Institute of Transport & Logistics Studies
Economic Sustainability = f(… • Demand for transport = function of • (land use, • demographics, • pricing, • alternatives modes) • Levels of service to be provided, load factors, route diversity • Magnitude of transport task • Energy consumption (joules/transport unit * Kilometres travelled) • Propulsion efficiency, unused capacity, • Other variable costs = f(journey time, number of vehicles) • Return on investment in fixed assets Chris Skinner – Seminar, Institute of Transport & Logistics Studies

INFORMATION AND COMMUNICATIONS TECHNOLOGY [ICT]FOR TRANSPORT & LOGISTICS AC21 - New Technologies for Sustainable Transport
Aftercasting – Telecommuting • An Aftercast compares earlier projection to the present actual outcomes • ‘Telematics is a relatively new area which develops new information technologies. It is anticipated to affect travel patterns and mobility partly through substitution of telecommunications for travel. Travel is expected to be replaced, or drastically reduced, mainly by telecommuting’ (Bovy 1990) p267 • Bovy reported on predictions that corporate regional centres would be set up to reduce the need for travel • Bovy also reports a Swiss study which projected reductions in commuter traffic due to teleworking of 8 to 15 percent over the period to 2025 • (Route Choice: Wayfinding in Transport NetworksP.H.L Bovy and E. Stern. Kluwer Academic Publishers. 1990 Section 7.2.2 Telematics) Chris Skinner – Seminar, Institute of Transport & Logistics Studies
Qualifications on the forecast • Telecommuting – assumed fixed places of work; fixed comms network • did NOT foresee mobility, wireless connectivity or ubiquitous networks including wireless and mobility, and • did NOT comprehend the motivational aspects of work location and accessibility • Telematics – was not originally associated exclusively with vehicle-based systems Chris Skinner – Seminar, Institute of Transport & Logistics Studies
Issues for Wireless ICT • 4C’s for wireless ICT • capacity, • coverage, • compatibility, • convenience => pervasive communications • Location-based services • Services-oriented architecture based on Web Services technology and standards • Security & privacy • Number of mobile phones > number of road vehicles Chris Skinner – Seminar, Institute of Transport & Logistics Studies
Implications for Transport & Logistics • The impact of time use and energy use for transport and communications will have an increasing impact on land use • Predictions should allow for disruptive changes in technologies plus the resulting innovation that flows from these break-throughs • Mobility will be part of everything we do • Workplace will not be defined by static physical domains • Energy economy costs of energy plus externalities will be part of pricing Chris Skinner – Seminar, Institute of Transport & Logistics Studies
