| Abstract | Based on the ability of a human eye to detect changes in the mode of operation of a moving object, two car-following models have been proposed. One uses the time-rate of change of visual angle as the stimulus; the other uses the second derivative of the visual angle as the stimulus. In both cases, the response was taken solely as the acceleration of the following vehicle. Provision for a time lag was incorporated into the analysis. From data which have been collected for queue-forming and queue-releasing conditions, the relationship between the stimulus and response was tested by fitting a least-squares regression line to each run. The coefficients of correlation obtained were quite high. Statistical comparisons between the correlation coefficients obtained from different models were made. Comparisons were made between the proposed models and the General Motors' model: a_ = f[(V. - V )/C]. The results of the analysis show that the d0/dt/ model provides an acceptable relationship between stimulus and response for an unsteady-state condition of traffic. the triangle d0/dt/triangle t model is statistically weaker than the other two models. However, the secondderivative model has served to introduce another idea into car-following theory; further studies may bring some light onto the value of such a model. Comparison of the time-lag values for different traffic conditions was made. The results show that the time-lag values for a given traffic condition and a particular model fall into a narrow range.
