SPR-4640: Geometric Constraints and Visual Field Related to Speed Management

The project deliverables will provide insights of how visual fields and optical cues affect perceived risks, speed perceptions, and driving speed, in different road locations. Based on the research outputs, cost-efficient road scene augmentation means that plants/shrubs, dividers, markings, overhead frames, or others will be designed. The strategy to implement certain levels of visual field restriction and types of optical cues at different locations will be discussed between the TASI research team and Indiana Department of Transportation (INDOT).
