Final answer:
Country roads have fewer traffic lights than city streets because they have less traffic and pedestrian density, thus less need for traffic control measures.
Step-by-step explanation:
Country roads generally have fewer traffic lights than city streets. In urban areas, the density of traffic and pedestrians is much higher, requiring more traffic control measures such as traffic lights to maintain safety and manage the flow of vehicles and pedestrians.
Traffic signals are often installed at intersections where there's a history of accidents or where there's a need to manage high volumes of traffic. In less populated rural areas, intersections are less busy, and there is less need for traffic lights. Instead, other forms of traffic control, such as stop signs or yield signs, may be used.
