Fewer.
Traffic control devices commonly found at intersections include traffic lights, stop signs, yield signs, and crosswalks. These devices help regulate the flow of traffic and determine the right-of-way for vehicles and pedestrians.
uncontrolled traffic intersections
The Magic Roundabout is listed as one of the 10 busiest intersections in the world and is simply a circle of traffic with no traffic control devices with which five different roads intersect it. Traffic flows counter-clockwise around the roundabout which is located in Swindon, England.
Traffic Control Devices
Flashing traffic lights are used when the control system is not functioning properly, or when there is very low level traffic (to the point that lights become unnecessary).
Low
Roundabouts are circular intersections designed to improve traffic flow and safety, allowing vehicles to navigate by yielding to traffic already in the circle. They typically do not require traffic officers for control, as their design promotes continuous movement and reduces the likelihood of collisions. Instead, drivers must follow signage and yield to vehicles in the roundabout. This contrasts with traditional intersections, which may require traffic signals or officers for regulation.

Without stoplights, traffic flow and safety at intersections would be chaotic. Intersections would become a free-for-all as there would be no regulated way to control the flow of vehicles. This could lead to an increase in accidents and congestion on the roads.
Some intersections have traffic lights instead of round abouts because there is too much traffic on some intersections for a roundabout to be safe. Roundabouts have to have a certain amount of traffic to be safe enough for no traffic light.
