Sight distance at intersections
WebSight distance at the intersection of a minor road (controlled by a stop sign) and a major road is an important element of road safety. Several models have been recently developed … Web16 hours ago · Director of engineering Rob Dickinson explained that this will provide better sight lines and will reduce the crossing distance for pedestrians. The city also plans to add more lighting to the intersection. The project has already been tendered, said Dickinson, and the city has been coordinating with Cycle Alberni on the effort.
