Progress in fuel consumption modelling for urban traffic management: R. Akeelik (ed.), ARR Research Report 124, Australian Road Research Board, 500 Burwood highway, Vermont South Victoria 3133, Australia

Abstract

The report collects together edited versions of four papers presented at an ARRB seminar on fuel consumption modelling on 9 October 1981, as well as two subsequent papers. The objective of the seminar was to focus on the issue of fuel consumption modelling and data needs for urban traffic management purposes. Part 1--Fuel Consumption Models and Data Needs for the Design and Evaluation of Urban Traffic Systems (Richardson, AJ and Akcelik, R), specifies the general requirements of a fuel consumption which is compatible with other elements of the traffic system analysis process. It then discusses an elemental of fuel consumption as the most appropriate model for traffic design and evaluation purposes. Parts 2 and 3--Prediction of Changes in Fuel Consumption: Two Examples (Akcelik, R) and On the Elemental Model of Fuel Consumption (Akcelik, R) discuss the elemental in more detail and explore its relation to the positive kinetic energy (pke) model. Part 4--Calibration and Application of two Fuel Consumption Models (Watson, HC) describes problems associated with fuel consumption measurement. The elemental and the PKE models are then discussed in detail and criticism of the elemental is provided. Part 5--Relation Between Two Fuel Consumption Models (Akcelik, R and Richardson, AJ and Watson, HC) presents a joint statement of the resolution of differences in the approaches adopted for developing simple fuel consumption models. It is shown that, subject to various simplifications and an unexplained term, the elemental and PKE models are very similar. Part 6--Some Results on Fuel Consumption Models (Akcelik, R and Bayley, C) reports on further studies which answer some of the questions raised in previous parts of the report. (TRRL)
