INCORPORATING FUEL CONSUMPTION MODELS INTO URBAN TRAFFIC ANALYSIS TECHNIQUES. NATIONAL ENERGY RESEARCH, DEVELOPMENT AND DEMONSTRATION PROGRAM; END OF GRANT REPORT

The NERDDP Project 1036, 'Incorporating Fuel Consumption Models Into Urban Traffic Analysis Techniques', has been conducted at ARRB over the period July, 1987 to November, 1988. The primary objectives of the project were to: (a) advance the knowledge of driver vehicle acceleration behaviour; (b) incorporate truck fuel consumption models into several existing traffic analysis techniques; and (c) improve the fuel estimation procedures in the SATURN traffic analysis package. The major technical tasks and the associated findings are detailed in previous reports and in forthcoming documentation updates of the SATURN system. This is the final report to the NERDD Committee. It summarises the primary findings from the technical tasks and demonstrates the value of the enhanced fuel consumption models. A more flexible acceleration time model has been developed, which should find use in micro simulation, traffic models. The previous hierarchy of car fuel consumption models has been generalised and now provides reliable estimates for a wide range of vehicle types. These models can be incorporated into a number of existing traffic models, and have been for the INSECT and SATURN models. A particularly important use of the new fuel consumption models is in estimating the effect of traffic control changes when there are heavy vehicles in the traffic stream. Stops are seen to have much more significant impacts on fuel consumption than was indicated by the previous car based fuel consumption models. The practical implication is that careful consideration should be given to all traffic performance variables (fuel consumption, safety, delay), when traffic system changes are being investigated.
