Methodology to calculate sight distance available to drivers at skewed intersections
TLDR
In this paper, a methodology was developed to calculate sight distance available to drivers at skewed intersections of minor roads that are controlled by stop signs, considering the fact that the sight distance may vary depending on the position of the driver and the different lines of sight given to the driver by different types of vehicles.Abstract:
A methodology was developed to calculate sight distance available to drivers at skewed intersections of minor roads that are controlled by stop signs. The methodology considers the fact that the sight distance may vary depending on the position of the driver and the different lines of sight given to the driver by different types of vehicles. Through field observations, factors are found that affect the sight distance available to drivers. The factors include intersection geometry, the vehicle's dimension, and the driver's field of view. With the sight triangle properly drawn, equations were developed for calculating the available sight distance considering these factors. Values of sight distance were compared with stopping-sight distance of vehicles on the crossroads by varying design speeds and intersection angles. Nomographs were developed that can be used by road designers or operators to check if a skewed intersection satisfies the sight-distance requirement.read more

Operational design domain of autonomous vehicles at skewed intersection
TL;DR: In this article, the authors investigated and quantified the relationship between intersection angle on skewed intersections, and found that the current intersection design criteria cannot provide sufficient sight distance for the AV if the approach speed is not controlled.

Lateral Vision Angles in Roadway Geometric Design
TL;DR: Taking into account the experimental lateral visibility design angles and the dimensions of the design vehicle, a new design has been proposed for merges during which no vehicle can be found in the driver's blind spot.
