Identification of driver car-following behaviour

A procedure is developed to identify the driver frequency response functions (FRF) of a serial multi-loop car-following model. It is shown that with a single forcing function both the inner-loop and outer-loop FRF's can be identified, although indirectly. Parameterisation of the driver FRF's is done using the concepts of the simplified precision model developed by McRuer and Krendel in the 1970's. The forcing function characteristics, data processing procedures, non-parametric and parametric identification are described. Experimental data are used to show the results of the identification procedure. In non-critical car-following situations (not requiring braking) the simplified precision model can be used as a linear description of driver car-following behaviours.
