MINIMUM ACCEPTABLE GAPS AND CONFLICT INVOLVEMENT IN A SIMPLE CROSSING MANOEUVRE

The authors analyse experimental data on minimum acceptable gaps and crossing times of subjects for a single-lane crossing manoeuvre. Data for four groups of subjects were used: young males, old males, young females and old females. A regression analysis was used to assess how judgments of minimum acceptable gap vary with speed of approaching vehicles. The results were used in a simulation model to estimate conflict involvement for each class of subject as a function of main-road flow and speed. Older drivers are more likely to cause conflicts in this manoeuvre than younger drivers and males are more likely to cause conflicts than females. (a) (TRRL)
