Three-Dimensional Stop-Control Intersection Sight Distance [PDF]
Transportation Research Record, 2006 Intersection 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.

Intersection sight distance analysis and guidelines
Transport Policy, 2009Guidelines for intersection sight distance are mostly outlined in general terms without showing effects of all the variables and assumptions involved. This paper provides theoretical analysis and sets guidelines based on the laws of motion for three types for intersection sight distances, namely (a) approach sight distance, (b) sign visibility sight ...

Reliability Approach to Intersection Sight Distance Design
Transportation Research Record, 2000The intersection sight distance (ISD) design presented by AASHTO is based on extreme values of the component design variables such as design speed, perception–reaction time (a high percentile), and friction coefficient (a low percentile). A reliability method is presented, based on AASHTO, that does not rely on extreme values but instead considers the ...

Geometric Models to Calculate Intersection Sight Distance for Unprotected Left-Turn Traffic [PDF]
Transportation Research Record: Journal of the Transportation Research Board, 2004 At signalized intersections with opposing left-turn lanes, inadequate sight distance of left-turn drivers caused by obstructions from opposing left-turn vehicles can not only contribute to a serious safety problem due to drivers misjudging the gaps in the opposing through traffic but also cause increased intersection delay.

Geometric Models to Calculate Left-Turn Sight Distance for Signalized Intersections on Horizontal Curves [PDF]
Journal of Transportation Engineering, 2006 At signalized intersections where protected left turn signals are not provided, simultaneous opposing left-turn vehicles may cause insufficient sight distance for each other. There is a lack of literature presenting left-turn sight distance analysis at intersections located on curved highways.

3D virtual intersection sight distance analysis using lidar data
Transportation Research Part C: Emerging Technologies, 2018Abstract Sight distance analyses require careful and detailed field measurements to facilitate proper engineering decision making regarding the removal of obstructions, establishment of regulatory and advisory speed limits, and the location of new access points, among numerous other purposes.

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 ...
