Following a review of the existing methods of obtaining repeated observations on drivers, simulated experiments on Sheffield park way are described together with those carried out in a car park and on broad lane. Data are also given on a round-the-block experiment. The factors investigated were gaps and lags, waiting times, vehicle speed and distance, vehicle type, length and height, direction of travel of vehicle closing gap, residual absolute gaps, previous critical gaps, colour of approaching vehicle, make and model, compensation for inconsistent behaviour, age, cubic capacity of the subject's vehicle engine, mileage in previous twelve months, seat belts, extroversion. The means and variances of critical gaps were shown to be highly correlated in all three experimental situations. /TRRL/
