A case study on the effects of visibility and other environmental factors on driver speed was conducted as part of an intelligent transportation systems field operational test to reduce accidents caused by sudden changes in visibility levels. Baseline conditions established normal vehicle speeds for passenger cars and trucks. Reduced visibility and winds exceeding 40 km/h were found to be the primary factors affecting driver speed.

Important institutional lessons learned in the course of the San Diego smart call box field operational test are presented. These lessons relate both to the conduct of the field test itself and to requirements for deployment of intelligent transportation systems similar to smart call boxes. The institutional issues were identified through review of project documents, interviews with participants, and the experience of the evaluator as a participant in the project. Issues were analyzed by preparing summaries that included a description and discussion of each issue, an assessment of its seriousness, identification of the organizational participants who raised it, a discussion of ways to avoid or mitigate any problems identified, and a list of actions to resolve the issue in the event of system deployment. Major institutional lessons include the potential impact of institutional arrangements on basic system concepts, the importance of involving potential users in the definition of system concepts and detailed design specifications, the need for quantitative market research to establish the potential profitability of intelligent transportation systems, the need for an adequate institutional infrastructure for deployment, and the importance of project organization schemes that minimize the number and complexity of formal agreements among participants.

The nation's motoring public is increasingly burdened by recalcitrant transportation problems, many of them directly attributable to increasing traffic congestion. In response to this, the US. Department of transportation is actively moving on several fronts to address this problem. One of the more promising approaches to relieving congestion is through the design and implementation of new technology in the Intelligent Vehicle/Highway System (IVHS). IVHS is composed of five elements: Advanced Traffic Management Systems (ATMS), Advanced Traveler Information Systems (ATIS), Commercial Vehicle Operations (CVO), Advanced Vehicle Control Systems (AVCS), and Advanced Public Transportation Systems (APTS). This paper will discuss human factors issues associated with ATIS.
