Who invented the traffic light drivers#

Although it was said to be successful at controlling traffic, its operational life was brief. At night a red light would command 'Stop' and a green light would mean use 'Caution'.

Who invented the traffic light drivers#

The light was called the semaphore and had arms that would extend horizontally that commanded drivers to 'Stop' and then the arms would lower to a 45 degrees angle to tell drivers to proceed with 'Caution'. The gas lantern was manually turned by a traffic police officer with a lever at its base so that the appropriate light faced traffic. The design combined three semaphore arms with red and green gas lamps for night-time use, on a pillar, operated by a police constable.

The main reason for the traffic light was that there was an overflow of horse-drawn traffic over Westminster Bridge which forced thousands of pedestrians to walk next to the Houses of Parliament. Knight of Nottingham who had adapted this idea from his design of railway signalling systems and constructed by the railway signal engineers of Saxby & Farmer. They were proposed by the railway engineer J. On 9 December 1868, the first non-electric gas-lit traffic lights were installed outside the Houses of Parliament in London to control the traffic in Bridge Street, Great George Street, and Parliament Street.

A second officer would direct traffic on the east side of the bridge to control the flow of people leaving London and going into Southwark. Each officer would help direct traffic coming out of Southwark into London and he made sure all traffic stayed on the west side of the bridge. Three men were given the task of directing traffic coming in and out of either London or Southwark. A well-documented example is that on London Bridge in 1722. Before traffic lights, traffic police controlled the flow of traffic.
