Improvement of maintenance visibility analysis method based on human visual field cone
Zhongguo Jianchuan Yanjiu, 2020 Objectives Since the visual cone maintenance visibility analysis method based on the visual field of the human eye cannot quantitatively evaluate visibility and visual field occlusion, an improved visibility evaluation model is proposed.Methods First ...

Interchange Sight Distance and Design: Aspects and Implementation
Open Journal of Civil Engineering, 2021 The primary purpose of an interchange is to enable an appropriate level of access to the freeway in a safe and beneficial way to the driver. It improves road safety and traffic operation by reducing or eliminating traffic conflicts that would occur if

What affects pedestrian crossing difficulty at urban intersections in a developing country?
IATSS Research, 2022 In developing countries, road traffic crashes involving pedestrians have become a foremost concern. At present, road safety assessment plans and selection of interventions are primarily restricted to traditional approaches that depend on the ...

The Effects of Restricted Sight Distances on Drivers at Simulated Rural Intersections [PDF]
Proceedings 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
Journal 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
Remote 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 ...

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

Impact of visibility on traffic Incidents at signalized intersections –a case study in Polish cities
Archives of TransportIn urban agglomerations, signalized intersections are common. However, in traffic management, safety-focused strategies are often sacrificed for traffic efficiency by allowing simultaneous multiple conflicting movements.
