The Impact Analysis of Intersection Sight Distance on Vehicle Speed
Traffic and Transportation Studies 2010, 2010Sight distance and vehicle speed are closely related to traffic safety, and good sight distance not only enable driver to judge the road traffic environment correctly, determine the correct driving behavior, but also determines effective operating time of the driving behavior.

Lidar Data-Based Method to Measure Sight Distance at Unsignalized Intersection
Transportation Research Record: Journal of the Transportation Research BoardAccurate assessment of intersection sight distance (ISD) is crucial for ensuring safety at unsignalized intersections. Traditional field measurement methods are labor-intensive, time-consuming, and susceptible to human error, while previous lidar-based approaches often rely on mobile lidar scanning systems, which have limited data coverage.

Three-Dimensional Model for Stop-Control Intersection Sight Distance
Journal of Transportation Engineering, 2004Intersection sight distance (ISD) is the distance to be provided at intersections between minor and major roads. Current AASHTO policy provides an equation and charts for the required at-grade ISD so that a driver on the minor road can depart (crossing, turning left or right) safely, even though an approaching vehicle on the major road comes into view ...

Estimating the Safety Effects of Intersection Sight Distance at Unsignalized Intersections
Transportation Research Record: Journal of the Transportation Research Board, 2016A gap acceptance crash is one of the most common types of multivehicle crashes at unsignalized intersections. Drivers’ gap acceptance is influenced by the intersection sight distance (ISD). Before this research, the relationship between ISD and safety (measured by crash frequency) at unsignalized intersections was not quantified.

Recent road accident statistics indicate that more than 30% of accidents occur at intersections. Whereas, total percentage of intersections present in the entire road network is less than 2%. From design point of view, one way to ensure reduction of accidents at intersections is to provide sufficient sight distance and clear sight triangles.

Three-Dimensional Stop-Control Intersection Sight Distance
Transportation Research Record: Journal of the Transportation Research Board, 2006Intersection sight distance is an important design element. A stopped vehicle on the minor road needs sufficient sight distance to depart (cross, turn left, or turn right) safely, even though an approaching vehicle on the major road comes into view. Current AASHTO policy assumes that both minor and major roads are straight and intersect at right angles.
