I have often wondered the exact same thing myself. The odd thing is no one seems to know the answer.
Types of roads
Many types of road exist around the world, all of which are thoroughfares which can be used by motorized traffic. Roads are not necessarily available for use by the general public without permission, highways are available for by the public, although a toll may be charged. In places the term 'highway' is reserved for high capacity roads, in older English there was a distinction between 'highways and Byways'.
Different terms are used in different countries for broadly the same design, although there are differences. For example Freeway USA, Motorway UK and Autobahn DE all of which are broadly similar.
Environmental design is the process of addressing surrounding environmental parameters when devising plans, programs, policies, buildings, or products. Classical prudent design may have always considered environmental factors; however, the environmental movement beginning in the 1940s has made the concept more explicit.
Environmental design can also refer to the applied arts and sciences dealing with creating the human-designed environment. These fields include architecture, geography, urban planning, landscape architecture, and interior design. Environmental design can also encompass interdisciplinary areas such as historical preservation and lighting design. In terms of a larger scope, environmental design has implications for the industrial design of products: innovative automobiles, wind-electricity generators, solar-electric equipment, and other kinds of equipment could serve as examples. Currently, the term has expanded to apply to ecological and sustainability issues.
In journalism, a human interest story is a feature story that discusses a person or people in an emotional way. It presents people and their problems, concerns, or achievements in a way that brings about interest, sympathy or motivation in the reader or viewer.
Human interest stories may be "the story behind the story" about an event, organization, or otherwise faceless historical happening, such as about the life of an individual soldier during wartime, an interview with a survivor of a natural disaster, a random act of kindness or profile of someone known for a career achievement.
