凱文•林奇(Kevin Lynch)在1960年發表的論文《城市形象》(Image of the City)中談到了城市的易讀性。他的意思是，城市的所有景觀、道路、森林區域、社區，以及隨着自然而來的發展的整體擴展，以及城市內部的發展，都描述了一種特定的模式，通過這種模式，城市的市民可以看到他們的城市(Lynch, 1960)。他進一步擴展了這一主題，強調了市民與他們居住的城市之間的情感聯繫，以及城市景觀和周圍環境如何產生社會影響。儘管在城市的某些部分的視覺形象中存在着迷失方向的現象，但是像太陽、沙子、空氣和開放空間這樣的自然資源對所有人來說都是平等的。
Kevin Lynch in his essay “Image of the City” published in 1960 talks about the legibility of the city. He means that all the city’s landscapes, roads, forest areas, communities, and the overall spread of development along with and inside nature describes a particular pattern through which the citizens of the city view their city (Lynch, 1960). He further expands the subject by emphasising on the emotional connection of the citizens with the city they live in, and how the city landscapes and surroundings have a social impact and influence. Even though there is disorientation in the visual image of some parts of a city, the natural resources like the sun, sand, air, and open spaces are available to all of them equally.
Legibility of a cityscape
By the legibility or clarity of a cityscape, Lynch means that the combined experience of all landscapes, pathways, developed structures, and open spaces in a city have a typical pattern with which the citizen negotiates and which also makes the city distinctive. He talks about the city as a whole with all its internally developed and undeveloped land and natural reserves, and considers it as having a specific design which makes the city identifiable. With the imageability of the cityscape, Lynch means that the visible physical environment has a quality which evokes a very strong visual and mental image in the minds of the observer, which he gets from the selection of different colour, size, design, etc.
Lynch thinks that citizens of a city are always a part of the city, and also experience it throughout. This experience makes them develop a specific image of the city, in the way it operates, it treats them, it develops, and fades in a way which is familiar and quite distinctive compared to other cities.
Brisbane Saturday fresh market
The city of Brisbane chosen is very much image-able and legible, because it is systemised and formulated to be operated in a specific way, to have in them the citizens, and to have those citizens propel its growth and discard unnecessary growth. The city pathways, the travel system, the movement of people around, the support of external infrastructure, etc. all makes Brisbane city recognisable with its unique and distinctive features. The city is legible in the way it stands and has gone through an unprecedented growth plan since it was first found.
