Hugh Woo Department of Transportation Technology Management National Chiao Tung University ABSTRACT This study proposes a procedure to quantitatively estimate cognitive distraction that are not accompanied by any visual diversions to clarify the influence of non-visual distractions to driving. In a laboratory experiment, mental capacities (measured in bits/sec) for three arithmetic tasks were estimated for each subject driver, using the functional relation between the reaction time and the number of alternatives in choice reaction tasks using a subsidiary task method through a mobile phone. The spare capacities obtained correlated significantlyly with the measures of speed control and physiological load during a lane change course negotiation on a test field. There are 18 subject drivers participate the two-part experiments. In the laboratory experiment, it was observed that a direct ratio between the reaction time and the amount of information exists as 5.2 bits/sec in non-arithmetic task4.92 bits/sec in easy-arithmetic task 4.87 bits/sec in moderate-arithmetic task, and 3.98 bits/sec in difficult-arithmetic task.
