The Effects of Restricted Sight Distances on Drivers at Simulated Rural Intersections [PDF]

open access: yesProceedings of the Human Factors and Ergonomics Society Annual Meeting, 2019
Short sight distances at rural intersections can result in reduced safety including drivers choosing smaller gaps between oncoming vehicles (Yan & Richards, 2010). Conversely, increased sight distances may result in improved driver confidence, but not safety as seen at rail crossings (Ward & Wilde, 1996). Thus, simply increasing sight distances

The mean point of vergence is biased under projection

open access: yesJournal of Eye Movement Research, 2019
The point of interest in three-dimensional space in eye tracking is often computed based on intersecting the lines of sight with geometry, or finding the point closest to the two lines of sight.

Integrated Multi-Sensor Real Time Pile Positioning Model and Its Application for Sea Piling

open access: yesRemote Sensing, 2020
The traditional pile positioning method for offshore piling uses the intersection of lines of sight with two or three theodolites. This method has certain limits, including using post-mission pile positioning, being time-consuming and lacking position ...

Examining the Effects of Sight Distance, Road Conditions, and Weather on Intersection Crash Severity: A Random Parameters Logit Approach with Heterogeneity in Means and Variances

open access: yesSafety
Intersections represent critical crash locations on road networks necessitating targeted safety interventions. This study employs a random parameters ordered logit (RPOL) model with heterogeneity in means to analyze injury severity contributing factors ...

An Eye-Tracker-Based 3D Point-of-Gaze Estimation Method Using Head Movement

open access: yesIEEE Access, 2019
Eye trackers are currently used to sense the positions of both the centers of the pupils and the point-of-gaze (POG) position on a screen, in keeping with the original objective for which they were designed; however, it remains difficult to measure the ...
