An important issue in the design of in-car navigation systems is what information to present to the driver. In this study, guidelines for information presentation were developed based on a brief review of the literature. Three different types of navigation information were subsequently compared in a field experiment. The different navigation instructions were: (1) arrows, (2) instructions using road signs (e.g., Follow Utrecht ), (3) multiple instructions presented simultaneously (e.g., Follow Utrecht , Follow Hoogland , Follow Leusden ). The instructions were presented on cards. Forty-two drivers, twenty-one male and twenty-one female, took part in the field study. Subjects followed navigation instructions on three different types of roads: highways, main roads within a city, and secondary roads in a residential area. Subjects were unfamiliar with the roads they drove on. Navigation errors, subjective workload estimates, and answers to questionnaires were recorded. The results showed that subjects performed worse on all measures when following multiple instructions as compared to single instructions (arrows or road signs). Multiple instructions were found particularly unclear and unreliable on the busy main roads within cities rather than on highways. No difference was found between arrows and single instructions using road signs.
