Txdot sight distance at intersection
Webintersection. The radius will need to be determined from field measurements. Once is known, Δ is determined as: Δ = 180 - 2. Once the radius of the curve has been determined, choose a slightly smaller radius (3 to 5 feet smaller than the radius of the intersection curve, but between 8.5 feet and 35 feet), R g, for the curved guardrail. WebWhere used, the barrier should be a minimum of 1.1 m (42 inches) high, to prevent bicyclists from toppling over it. A barrier between a shared use path and adjacent highway should not impair sight distance at intersections, and should be designed to not be a hazard to errant motorists. Width and Clearance
