Models of Driving: Simulator Assessment of Adaptive Cruise Control Conceptual Understanding

Drivers have poor conceptual understanding of new adaptive driver safety systems (ADAS) such as adaptive cruise control (ACC). When using advanced safety systems, older drivers tend to be more open to learning through reading manuals, but also tend to struggle with learning the uses and limitations of a safety system. Different instructional formats can have different training effects for older learners. These can run counter to intuitive expectation that older drivers will be more comfortable with, and therefore learn more from, traditional instructional formats such as books or manuals. This study compared the efficacy of different forms of instruction (informational text, problem-based scenarios, interactive game scenarios) for older and younger drivers learning about ACC systems. The study used a repeated measures design to look at drivers’ conceptual understanding of ACC before and after instruction and after simulator driving experience. The authors found that the participants performed the same on the test of conceptual understanding of ACC before they received any instruction; however, after receiving instruction and after using the driving simulator participants in the Text condition performed significantly better than those in the Interactive condition. The authors also saw differences in performance on one of the events in the driving simulator. In this event, drivers approach a truck pulling a low trailer and must brake (disengaging ACC) in order to avoid a collision. Younger drivers seem to show a greater benefit from the scenario-based instruction (braking earlier), while older drivers did not. Overall, drivers in the Text condition performed better than the other two instructional formats on this event.
