two <strong>of</strong> the six test scenarios and only when the simulator had a wide field <strong>of</strong><br />

view. There was not one significant effect when the training simulator had a<br />

narrow field <strong>of</strong> view. In the two test scenarios some effect was found were<br />

near transfer scenarios. A possible explanation for the rather poor results is<br />

the fact that the didactical opportunities that simulators <strong>of</strong>fer were not fully<br />

utilized in this training program. In case <strong>of</strong> a crash participants only had to<br />

drive through the same scenario again.<br />

A fourth simulator-based training program that among others was aimed to<br />

enhance the higher order skills <strong>of</strong> <strong>novice</strong> <strong>drivers</strong> such as hazard perception,<br />

situation awareness and decision making under time pressure, is the Driver<br />

Assessment and Training System (DATS) (Allen et al., 2003; Allen, Park, &<br />

Cook, 2008; Allen et al., 2007; Allen et al., 2002). In the part <strong>of</strong> this training<br />

program that addresses the mentioned higher order skills, students drive in<br />

scenarios that contain critical events. These events are situations in which<br />

various types <strong>of</strong> collisions are elicited, such as pedestrians that walked out or<br />

cars on a collision course at intersections. All hazards are imminent hazards.<br />

The other road users that create the critical situations are automatically<br />

triggered by the driving behaviour <strong>of</strong> the student. If for instance a student<br />

drives fast, the pedestrian that start to cross the road also walks fast. During<br />

each drive, performance indicators such as speed, time to collision, and<br />

traffic signal violations are automatically recorded. Only when the scoring<br />

meets a certain criterion the students can graduate to the next training<br />

scenario. If the criterion is not met, students have to drive through additional<br />

scenarios. The crash data (recorded by the police) <strong>of</strong> three large groups <strong>of</strong><br />

students that did DATS during their initial driver training were compared<br />

over a two year period after licensing. The first group did DATS on a<br />

desktop simulator with one monitor (narrow field <strong>of</strong> view), the second group<br />

did DATS on a desktop simulator with three monitors (wide field <strong>of</strong> view)<br />

and the third group did DATS in a vehicle cab simulator with a wide field <strong>of</strong><br />

view. The development over time <strong>of</strong> the cumulative crash rate <strong>of</strong> the single<br />

monitor group was about the same as that <strong>of</strong> a control group that did not do<br />

DATS. The cumulative crash rate <strong>of</strong> the group that did DATS on the 3<br />

monitor desktop configuration was at all times somewhat lower than the<br />

cumulative crash rate <strong>of</strong> the single monitor group and the cumulative crash<br />

rate <strong>of</strong> the group that did DATS in the wide screen vehicle cab configuration<br />

was considerably lower at all times than that <strong>of</strong> the single monitor group.<br />

However, these results have to be interpreted with caution. There was no<br />

random assignment <strong>of</strong> the participants to the various groups. The<br />

participants in the one and three monitor desktop groups were high school<br />
