| 摘要： | ADVANCE (Advanced Driver and Vehicle Advisory Navigation Concept) is an in-vehicle navigation and guidance system for enhancing localized travel. Its automated Mobile Navigation Assistant (MNA) interface, is one of several Intelligent Transportation System (ITS) prototypes of Advanced Traveler Information Systems (ATIS) for highway vehicles. The ADVANCE project Included an operational field test to evaluate various ADVANCE system components. The National Highway Traffic Safety Administration (NHTSA) has sponsored the safety evaluation of the ADVANCE MNA based on the operational field test. The main objectives of the evaluation were to (1) determine whether drivers drive more, or less, safely with the system than without it in ways related to the system. (2) extend the knowledge base of ATIS use for navigation, and (3) gain Insight into ATIS design improvements. The study examined the variable effects of using four navigation scenarios on driving and navigation performance by 60 test subjects, traversing a set of four common routes, using a highly instrumented test vehicle for gathering safety related data. The scenarios were (1) MNA with voice supplement. (2) MNA without voice supplement. (3) a paper map. and (4) a textual paper direction list. The preponderance of evidence suggests drivers drive equally as safe with the MNA as without it. when the MNA is used to navigate to unfamiliar destinations. ADVANCE users indicated that the voice supplement was easily understood, provided relief from distractions, and enhanced feeling of safety over the direction list or paper map. On the other hand, their eye glance and safety performance suggested that the voice did not appreciably change the visual demands or error rate of navigation. Considering the contrasting results of prior ATIS evaluations, the precision and Informational clarity of the MNA voice supplement was called into question. With design Improvements. MNA auditory guidance has the potential to further reduce driver workload, yield fewer driver errors, and enhance the safety preference of users. |
