In 1868, the first traffic light was built in front of the British House of Parliament.
Even though there were not yet cars on the road, the horses and pedestrians caused chaos on the streets of London. The light was proposed by John Peake Knight, a railroad engineer.
Traffic lights were used in London from the 20th century. The first traffic lights in London were installed in Piccadilly Circus (1926), Ludgate Circus (1930-1932), and even on the corner of Cornhill and Bishopsgate.

Stop lights, also known as traffic lights or traffic signals, were first installed in London, England. The first traffic signal was installed in 1868 to to help control traffic.
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).

Logically, unless there were reasons to control traffic, there would have been no reason to create or install traffic lights. Because "traffic" generally comprises vehicles (motorized or otherwise), the traffic was probably there prior to the lights. Certainly, there were mechanical traffic signals that preceded traffic lights, not to mention traffic officers who once stood at busy intersections to direct traffic on a regular basis.
