Résumé / Abstract
This paper presents some empirical time headways observed on rural roads in France, and proposes a model relating the time gaps to the traffic flow, to the percentage of long vehicles, to the number of lanes; the influence of the period of the day is discussed. The parameters of the models characterise either the random arrivals, or the drivers behaviour. Their evolution in the future will show how the new French legislation on time gaps (to drive at a minimum threshold of two seconds) is respected.
