Empirical modeling of the relationship between decision sight distance and stopping sight distance based on AASHTO [PDF]
Archives of Transport, 2018 The paper introduces implementation of highways' stopping sight distance (SSD) and decision sight distance (DSD) based on AASHTO modeling assumptions. SSD characterizes the necessary distance for highway vehicles to stop safely in front from an obstacle.

Revision of Calculation of Stopping Sight Distance
The Baltic Journal of Road and Bridge Engineering, 2011 Stopping Sight Distance (SSD) is a critical parameter for roadway geometric design and safety evaluation. It experienced several revisions in AASHTO Green Books (A Policy on Geometric Design of Highways and Streets) since 1940.

Sight distances at unsignalized intersections: a comparison of guidelines and requirements for human drivers and autonomous vehicles [PDF]
Archives of Transport, 2021 Many traffic accidents are caused by unforeseen and unexpected events in a site that was hidden from the driver's eyes. Road design parameters determining required visibility are based on relationships formulated decades ago.
