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.
