“This paper describes the driver performance and behavioral interaction results of a comparison between visitors to a major city (Orlando) and local drivers while using differing navigation configurations of an Advanced Traveler Information System (ATIS). The system utilized for the study was TravTek, a device which provided in-vehicle information via color touch screen CRT, steering wheel buttons, and synthesized voice. The TravTek driver interface was developed with the intent of providing navigation, service and attractions, and roadway incident and traffic information to the driver. Both visitors and local users tested six different navigation-aid configurations. The six navigation-aids included: static turn-by-turn graphics and a moving map both with and without voice, a paper map and a textual direction list. The research showed that visitors drove more cautiously, but they made more glances to the navigation-aids when compared to local users. In addition, visitors went off-route and got lost less frequently than local users. Visitors apparently were more careful in driving and navigating to their destinations.”

McGehee, Daniel V., Dingus, Thomas A. and Horowitz, Avraham D. (1994): An Experimental Field Test of Automotive Headway Maintenance/Collision Warning Visual Displays. In: Proceedings of the Human Factors and Ergonomics Society 38th Annual Meeting 1994. pp. 1099-1103.
“Motor vehicle crashes resulting from one vehicle striking the rear-end of another are one of the most common types of crashes involving two or more vehicles. The National Safety Council reported (Accident Facts, 1992) that there were approximately 11.3 million motor vehicle crashes in 1991 of which 2.7 million were rear-end crashes (about 23.8% of the total). These crashes accounted for 33% of all collisions involving two or more vehicles. To address the rear-end crash problem, a color LCD display designed to indicate safe following distances was mounted in the instrument panel of an 1990 Olds Toronado Trofeo. The vehicle was also equipped with a laser range finder, forward view video camera, eye view camera, video multiplexer, and computer-controlled video cassette recorder. One hundred and eight drivers from three age groups participated in this field experiment in one of three display symbology conditions. Drivers were not explicitly instructed on how to use the headway displays. Data analyses indicated that (1) the drivers easily understood the displays, (2) those drivers who initially maintained unsafe headways increased their following distance when one of the display symbologies was used, (3) during events where changes in relative velocity (braking) took place, all three symbologies increased the overall headways, and (4) drivers preferred and understood, even better, displays that included graded headway/warning information.”

“The TravTek system constitutes a major Intelligent Vehicle-Highway System (IVHS) Advanced Traveler Information System (ATIS) demonstration project. The system provided in-vehicle information via color touchscreen CRT, steering wheel buttons, and synthesized voice. The TravTek driver interface was developed with the intent of providing navigation, service and attractions, and roadway incident and traffic information to the driver. The design of the TravTek interface had as its primary objectives: (1) more effective driver navigation providing the benefit of saving time, (2) easy access to valuable and convenient location information to alleviate stress and increase driving enjoyment, (3) maintenance of safe driving performance during system use and safety improvement facilitated by information for avoiding hazards and for emergency response, and (4) improvement of roadway efficiency to alleviate congestion. This paper provides detailed data regarding driver performance and behavioral interactions with four TravTek navigation configurations and two conventional methods of navigation: a paper map and a textual direction list. The results indicate that turn-by-turn information, regardless of its method of presentation, results in effective driving and navigation performance. A moving map display with no supplemental information required high visual attention relative to the other conditions. The other TravTek conditions resulted in lower workload superior navigation performance than the paper map control condition.”

McGehee, Daniel V., Dingus, Thomas A. and Horowitz, Avraham D. (1992): The Potential Value of a Front-to-Rear-End Collision Warning System Based on Factors of Driver Behavior, Visual Perception and Brake Reaction Time. In: Proceedings of the Human Factors Society 36th Annual Meeting 1992. pp. 1003-1005.
“The potential value of a front-to-rear-end collision warning system based on factors of driver behavior, visual perception and brake reaction time is examined in this paper. Twenty-four percent of all motor vehicle crashes involving two or more vehicles are front-to-rear-end collisions. These collisions demonstrate that several driver performance factors are common. The literature indicates that drivers use the relative size and the visual angle of the vehicle ahead when making judgments regarding depth. In addition, drivers often have difficulty gauging velocity differences and depth cues between themselves and the vehicle they are following. Finally, drivers often follow at distances that are closer than brake-reaction time permits for accident avoidance. It is apparent that the comfort level of close following behavior increases over time due to the rarity of consequences. Experience also teaches drivers that the vehicle in front does not suddenly slow down very often. On the basis of these driver behavior and human performance issues, a front-to-rear-end collision warning system that provides headway/following distance and velocity change information is considered. Based on the driver performance issues, display design recommendations are outlined. The value of such a device may be demonstrated by the added driver safety and situation awareness provided. The long-term goal would ultimately be the reduction of one of the most frequent type of automobile crashes.”
