A reference book of driving cycles for use in the measurement of road vehicle emissions

TRL Limited was commissioned by the Department for Transport to review the approach used in the National Atmospheric Emissions Inventory (NAEI) forestimating emissions from road vehicles, and to propose new methodologies. This necessarily requires that some consideration be given to the emission measurement process, an important aspect of which is the definition andapplication of driving cycles to represent different types of vehicle operation.uThis Reference Book represents an attempt to compile a unique document which contains detailed descriptions of more than 200 driving cycles in a standardised format. Emphasis has been given to those driving cycles and vehicle operations that are relevant to the UK. The Reference Book wasdesigned for use primarily within the DfT project. However, it is also hoped that it will be a useful source of information for other researchers and practitioners in the fields of vehicle emissions and air pollution. (A)
