A New Stopping Sight Distance Model and Fuzzy Reliability Analysis Comparison
IEEE Access, 2022 Aiming at the problem that the existing stopping sight distance model is out of sync with the development of the times, this paper puts forward a new stopping sight distance model considering the fuzziness and randomness of design parameters, and deduces

Revision of Calculation of Stopping Sight Distance
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.

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.

A New Model of Stopping Sight Distance of Curve Braking Based on Vehicle Dynamics
Discrete Dynamics in Nature and Society, 2016 Compared with straight-line braking, cornering brake has longer braking distance and poorer stability. Therefore, drivers are more prone to making mistakes. The braking process and the dynamics of vehicles in emergency situations on curves were analyzed.

Modeling of Unsymmetrical Single-Lane Roundabouts Based on Stopping Sight Distance
KSCE Journal of Civil Engineering, 2019 Evaluation of the adequacy of sight distance at roundabout is usually performed graphically as no quantitative guidelines are available for the lateral clearance needs. This paper presents analytical lateral clearance models to satisfy Stopping Sight Distance (SSD) at unsymmetrical single-lane roundabouts (with different entry and exit radii).
