Mobile Urinal On The Streets

Originally the word "street" simply meant a paved road (Latin: "via strata"). The word "street" is still sometimes used colloquially as a synonym for "road", for example in connection with the ancient Watling Street, but city residents and urban planners draw a crucial modern distinction: a road's main function is transportation, while streets facilitate public interaction. Examples of streets include pedestrian streets, alleys, and city-centre streets too crowded for road vehicles to pass. Conversely, highways and motorways are types of roads, but few would refer to them as streets.
Etymology
The word street has its origins in the Latin strata (meaning "paved road"); it is thus related to stratum and stratification. Old English applied the word to Roman roads in Britain such as Ermin Street, Watling Street, etc. Later it acquired a dialectical meaning of "straggling village", which were often laid out on the verges of Roman roads. In the Middle Ages, a road was a way people travelled, with street applied specifically to paved ways.
