Speed Estimation from a Moving Automobile
TLDR
In this paper, the role played by the senses of sight and hearing in the estimation of speed from a moving automobile was investigated, where subjects were driven in the front seat of a car whose speedometer was hidden from their view.Abstract:
An experiment is described in which the role played by the senses of sight and hearing in the estimation of speed from a moving automobile was investigated. Subjects were driven in the front seat of a car whose speedometer was hidden from their view. The subjects' task was to estimate the speed of the car under the following four conditions of sensory awareness: (A) normal passenger; (B) unable to see— the subject wore a blindfold; (C) diminished hearing— the subject wore a sound excluder; (D) the subject wore both a blindfold and a sound excluder. Under all four conditions slow speeds (25 mph or less) were, on average, underestimated. For the two conditions which permitted hearing the mean estimates of normal driving speeds were without systematic error. However, for the two conditions involving diminished hearing the mean estimates were always lower than the set speeds, indicating that the sense of hearing is of great importance in the task of speed estimation. A subjective speed scale, which is not of ...read more

TL;DR: It is hypothesize that lamellar flow is necessary for accurate speed perception, and that a limited field of view eliminates this cue during straight-ahead gaze.

TL;DR: Age was significantly and positively correlated with intercepts, but negatively correlated with exponents; that is, older observers showed less sensitivity to changes in actual velocity.

Navigating through a virtual city: Using virtual reality technology to study human action and perception
TL;DR: The paper outlines the motivations of researchers in this field to start using virtual environments for their studies by presenting two such studies conducted in the laboratory and data on the phenomenon that observers tend to underestimate the perceived speed of their movement through a virtual environment.

Perception of speed in an automobile: Estimation and production.
Miguel A. Recarte,Luís Nunes +1 more
TL;DR: In this article, the authors studied the perception of speed in an automobile as a function of speed, previous acceleration, trajectory, driving experience, and sex of the participants, and found that participants tend to underestimate speed, and this effect was more pronounced at lower speeds.

The development, validation, and application of a video-based technique for measuring an everyday risk-taking behavior: drivers' speed choice.
TL;DR: In this paper, the authors developed, validated, and applied a measure of drivers' speed choice that combined a high degree of experimental control with external and ecological validity, and found that increasing the level of internal car noise decreased drivers' preferred speeds.

A Subjective Scale of Speed when Driving a Motor Vehicle
TL;DR: An experiment is described which attempts to establish a subjective scale of speed, or more precisely of passive locomotion, such as that experienced by the driver of a motor vehicle, and it is found that n is not a constant, but has a definite correlation with speed.
