Explanation:
Three types of traffic control devices are b) Traffic lights, road signs, highway markers. These devices are designed to manage vehicle and pedestrian traffic safely and efficiently. For example, traffic lights control the flow of traffic through intersections, ensuring that vehicles take turns to move and reducing the chances of accidents. In addition, road signs provide important information and instructions to drivers, such as speed limits, directions, and warnings about hazards. Highway markers indicate lanes, routes, distances, and other guidance to facilitate safe and informed driving.
Installing traffic signals at problematic intersections can significantly reduce the incidence of vehicles speeding and improve pedestrian safety by regulating the flow of traffic and allowing people to cross at appropriate times. In situations where there are frequent accidents, the addition of a traffic signal can be a measure to prevent further incidents and losses of life.
