In a simulated driving scenario, we investigated the production of vehicle velocity at 30 and 60 mph while varying the amount of optical flow (roadside trees versus no trees) and the geometric field of view (25, 55, and 85 horizontal degrees). Participant drivers were significantly less accurate in producing vehicle velocities of 30 mph as contrasted with those of the 60 mph target set. On average, the produced velocities were overestimated by 20 mph for the 30 mph target set. This may be due to an inability of driving simulators to produce authentic optical flows when traversing at 30 mph or lower velocities.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
