During the Industrial revolution different types of transportation developed and a traditional streetscape formed. It was chaotic because there was no rules of where which type of transport should go etc.
In the 20th Century urbanism traffic was organized in to some sort of layers but soon enough a more structured manner was needed.
The public was separated into dedicated zones for different modes of transport and that type of zones are still used in our contemporary world and it works effectively and makes everything faster.
Transport started developing in the 18th century. The middle of the 18th century the first horse-drive railways were build. In 1803 the first locomotive was up and running. Steamships and steam locomotives gave a boost to industrialization. The first railway line was built in 1825. Never was it enough and the search to a faster and greater way of transportation went on. In 1859 the first gas engine was built and not long after that in 1885 the four stroke motor was put into motion. From there on it evolved into bigger and better cars. Cars with features that makes life extremely easy but more so made communication easier because it was faster and more reliable.
Earlier communication depended on transportation. It started with letter that were hand written and travelled to the receiver, this took more than weeks and then the receiver still had to reply by letter and so it went on. By the development of transportation the postal system became more effective and expanded rapidly.
Developments did not end there; this is just a broad overview on how communication is reliable of transportation. Every day somebody is experimenting with something faster something more reliable and something to make life easier for all of us.
