FOREWORD

This report is one of a series of nine reports produced as part of a contract designed to develop precise, detailed human factors design guidelines for Advanced Traveler Information Systems (ATIS) and Commercial Vehicle Operations (CVO). Among the other topics discussed in the series are functional description of ATIS/CVO, comparable systems analysis, task analysis of ATIS/CVO functions, alternate systems analysis, identification and exploration of driver acceptance, and definition and prioritization of research studies.

This report documents ATIS and CVO system objectives and performance requirements. It provides basic information regarding the range of ATIS and CVO operational capabilities, a survey of ATIS and CVO systems, a preliminary set of ATIS and CVO scenarios, and a summary of system performance requirements.

16. Abstract

This working paper documents Task E of the present project, Task Analyses for Advanced Traveler Information Systems (ATIS) and Commercial Vehicle Operations (CVO) systems. The goal of Task E is to conduct detailed analyses of the influence of using ATIS on driving tasks for both private and commercial vehicle operators. The task analyses specifying the tasks to be performed by the users as well as the information displayed in the ATIS (including IRANS, IMSIS, ISIS, and IVSAWS) are based on scenarios developed from previous project tasks. Information for the task analysis was obtained from a review of the literature, observations, and interviews of drivers and dispatchers using prototype and first-generation operational systems. The report organizes the tasks people and systems do while driving into three usable formats: (1) a graphical representation of the interactions that take place between driving and ATIS/CVO functions; (2) a diagram (i.e., an Operational Sequence Diagram [OSD]) of the sequence of task actions, the types of tasks involved, and the relationship between various human and non-human parts of the system; and (3) a description of each task in terms of its purpose, initiating conditions, task type, and performance considerations. General characteristics and performance considerations are examined for four types of tasks: setup, bridging, decision-making, and integrated. A summary of research issues and additional research needs are identified.
