Fu and Yang [5] propose a scheme which can minimize the variation of headways and provide better service for passengers.
This model has two major limitations: it generates unrealistic short headways and does not describe platoons; consequently, it only deals realistically with very low traffic flows (q < 100 vph (vehicles per hour) (Luttinen 1999).
The Table 1 also shows that high flow conditions, a high percent of drivers in the passing lane and more than half of drivers in the middle lane choose the headways less than safe headway.

There is, however, one other reason for the short headways, and it is that drivers are incapable of estimating headways correctly.
25, yet there was a statistical difference between pre exposure headways and the headways in the fourth trial (see above), showing a long-term learning effect of headway maintenance.
Ohta (1993) found that drivers' actual headways range between the minimal headways perceived as safe and the headways at which drivers feel that "they are not too close and not too far" from the vehicle ahead.
This effect of short PRTs for short headways was explained by increased attention drivers gave to the lead vehicle.
There were 120 combinations of vehicle speeds for the two types of roads (2) x headways between the two vehicles (5) x expectancy/alertness levels of the following driver (2) x coefficients of friction between the road and the tires (3) x the presence or absence of ABWS on the lead vehicle (2).
