Abstract

The driver intercept method is commonly used to conduct origin-destination studies. In this method, vehicles passing a location are intercepted and a questionnaire is administered to drivers. Although effective control of driver behavior is essential to avoid injury or death to travelers and field interviewers, typical flaggers lack a conceptual model of the factors that control human behavior. This article describes how a flagger in a driver intercept study can control driver behavior using signals based on factors identified in a behavior engineering model developed in the 1970s. These factors are information, resources and incentives. A four-step process to control driver behavior based on these factors has been shown to be effective: get the attention of the driver, communicate expectations; give feedback; and reward compliance. Using the signals outlined in this article can reduce injury risk to both interviewers and travelers.
