... 56 A p p e n d i x B priority 1 Global Research Question 1: How Do Dynamic Driver Characteristics, as Observed Through Driver Performance Measures, Influence Crash Likelihood? These questions relate to how driver states (e.g., aggressiveness, drowsiness, willingness to engage in distracting activities)
From page 57...
... 57 and/or does a lane departure over a rumble strip improve subsequent lane keeping and decrease the frequency of lane departures? • How does the driver's positioning of the vehicle affect lane keeping, and how is this related to the efficacy of edge marking and rumble strips?
From page 58...
... 58 likelihood of crash surrogate events. This global research question represents 23 individual research questions: • Are drivers less likely to lose control with antilock braking systems?
From page 59...
... 59 Global Research Question 9a: What Variables or Pre-Event Factors Are the Most Effective Crash Surrogate Measures? These questions relate to different factors or events that can be used as crash surrogate measures most effectively.
From page 60...
... 60 • What key driver, roadway, and environmental factors affect lane keeping that may result in a road departure? • What is the influence of life events and factors on ROR events?
From page 61...
... 61 ability to see pedestrians, animals, or objects in the travel lane? • What are the benefits of reflectors and reflective clothing, and under what circumstances do these items improve drivers' ability to see pedestrians, animals, or objects in the travel lane?
From page 62...
... 62 • What are the intra- and interindividual differences in braking and crash-avoidance skill? • What are the intra- and interindividual differences in willingness to pass and skill in passing?
From page 63...
... 63 • What is the role of driver factors in the risk associated with inappropriate gap acceptance with opposing traffic on left turns? • What is the role of driver factors in the risk associated with inappropriate gap acceptance with opposing traffic on right turns?
From page 64...
... 64 Global Research Question 15: How Do Individual Differences (e.g., Age, Gender, or Speed Selection) Influence Lane-Keeping Performance?
From page 65...
... 65 related tasks (e.g., original equipment manufacturer [OEM] , technology, or nomadic devices)
From page 66...
... 66 • Where do drivers position their vehicles in the travel lane on two-lane and two-way roads (using a simply painted centerline and gravel shoulders as baseline) , and is this position influenced by factors such as opposing traffic volumes, centerline rumble strips, shoulder treatments, curbs, and weather?
From page 67...
... 67 Global Research Question 23: How Do Roadway Features Influence Driver Performance and Behavior? These questions relate to the effect that specific roadway features (e.g., rumble strips or glare from lighting)
From page 68...
... 68 • How does distraction influence speed behavior at intersections? • Does driver distraction influence compliance with traffic controls at intersections?
From page 69...
... 69 Global Research Question 27: What Nonsafety-Related but Useful Information Can Be Obtained from These Data? These questions relate to other useful information (e.g., how often alerts occur and how drivers respond to them)
