Driver Behaviour
Cellphones and mental workload
2001 Masters' Thesis by R Mathews |
Cell phones do not produce reliable changes in drivers’ speeds or lane position because these components of driving are proceduralised
(i.e., do not require conscious attention).
Cell phones do produce significant increases in drivers’ cognitive workload and brake-perception reaction times (BRTs).
Hands-free cell phones are not significantly different than hand-held models in terms of their effects on driver workload and driver performance.
Speech intelligibility does make a significant difference in drivers’ cognitive workload.
