Human Factors Requirements for Real-Time Motorist Information Displays. Volume 6. Questionnaire Survey of Motorist Route Selection Criteria

摘要

Two questionnaire surveys were conducted to determine the criteria used by motorists in selecting among alternative routes in typical and route diversion situations. One survey was administered to 215 motorists at rest stops on an interstate leading into a large metropolitan area. The other survey was administered to 202 motorists working in seven CBD firms in another large city. These motorists were commuters and highly familiar with the area. The samples of drivers were asked a series of questions regarding their typical driving habits and their expected or recalled driving behavior in incident-type situations. After each statement of driving behavior, probing questions sought to determine the reasons for such actions in terms of characteristics of the primary or alternate routes. The focus of both questionnaires was to determine the types of information which would be critical to making a route-choice or route-diversion decision.
