In-vehicle information presentation to drivers can influence driving behavior. This study clarifies the impact on driving behavior of the processing demand caused by information presentation in specific traffic situations. Applying a subsidiary task procedure devised in the authors' previous study, processing demand in traffic situations and information presentatiom tasks were estimated as decrements in the remaining capacity of drivers. For the presentation tasks used in this study, the processing demand per unit time was estimated to range from 2.7 to 4.5 bits/s. Driving behavior became worse when both the traffic situation and the information presentation task imposed large demands, but did not become worse when one or both of the sources imposed only a few demands. Based on the obtained results, a possible approach to information presentation corresponding to the processing demand of traffic situations is discussed.
