Abstract

This paper revealed effects of cognitive distraction on driver intent of changing lanes. We conducted an experiment to collect data of driver's eye-movement on checking traffic conditions and driving behavior in lane changes in two conditions: driving only and performing a secondary task during driving. The result indicated that there were two types of changes in terms of the intent: (1) driver intent emerges lately and (2) the intent emerges without enough checking on traffic conditions. The investigation also showed that a driver made a decision of changing lanes in a relatively short time period due to driver distraction, which might increase risk in driving. Those findings implied necessity for an intent detection method adaptive to driver psychological state.
