A New Stopping Sight Distance Model and Fuzzy Reliability Analysis Comparison
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

Empirical modeling of the relationship between decision sight distance and stopping sight distance based on AASHTO [PDF]
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
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.

A New Model of Stopping Sight Distance of Curve Braking Based on Vehicle Dynamics
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.
