Cognitive/Decisionmaking Aspects of Decisions to Go or Stop on Late Yellow/Early Red Lightġ. Graphic 2 used to describe scenario 1: Red-light running. Stop if he/she brakes hard, but is likely to enter the intersection on an early red if he/sheįigure 3. The driver is far enough away from the intersection that he/she can Scenario 1 was described to the focus group participants using the graphics shown below inįigures 2 and 3 with the following verbal description: “Approaching a signalized intersection at PARTICIPANT RESPONSES TO THE FOUR DRIVING SCENARIOS Scenario 1: Red-Light Running For example, “1.1” refers to the first countermeasureĭiscussed within Scenario 1, and “1.2” refers to the second countermeasure discussed within Scenario 1.īelow both the discussion of scenarios and countermeasures include anecdotal quotes from the To the relevant countermeasure associated with that scenario. In general, the discussion focused on describing each countermeasure,ĭetermining if drivers believed that the countermeasure would improve safety, and then gaining an understanding of the perceived implementation issues, advantages, and disadvantagesģ All of the countermeasures are labeled using an “X.Y” designation, where ”X“ refers to the scenario and “Y” refers The Moderator Guide in appendix B provides a step-by-step overview of the discussion flow for 3.2: Synchronized adjacent traffic signals.

1.4: Intersection collision warning systems.1.3: Advance traffic light warning signs.Next, we addressed the participants’ opinions of and responses to the nine countermeasures Understanding of driver behavior in the scenarios (i.e., How do drivers behave in this situation?),Īnd understanding the many primary and secondary factors (e.g., situations, attitudes, habits,īeliefs, consequences, etc.) that influence their decisions and behaviors (i.e., Why do drivers In general, the discussion focused on describing each scenario, gaining an The Moderator Guide in appendix B gives a step-by-step overview of the discussion flow for the Scenario 3: Turning Left on Major Roads with Moderate Traffic.Scenario 2: Left Turns at Busy Intersections.The four scenarios addressed in the focus groups and discussed below are: Specifically, the discussionįlow for each scenario presented below first addresses behaviors, then the decisionmakingįactors that more or less directly influence these behaviors, and then complicating factorsĮncountered in the four intersection scenarios presented to the respondents.
