The photograph attached is of one of the busy streets in the city of Nairobi. VISIBLE INFORMATION The information that is visible in the attached picture is: • Traffic – “matatus” which are known as the main public transport system in the city. These consist of minivans and buses. The road in the photography is a two-way traffic road, however, the indiscipline of the matatu drivers is clearly exhibited. The photograph depicts chaos. • Architecture – the buildings exhibit the type of architecture found in the city. Mixed-use buildings, with offices on the top stories and shops in the ground stories. Most of the buildings are geometrical in nature, concrete framed structures with stone in-fill. There is use of colour. • People – the number of people appear many, some using public transport, others are pedestrian. The sidewalks are buzzing with people and there is no presence of pedestrian crossings. There is a man standing in between buses, in attempt to cross the road. This could be dangerous and could lead to accidents as well. • Advertising – the presence of billboards shows that advertising is done via this means in the city, among many others. Advertising is a mode of communicating a type of information e.g. brand advertising, institutional advertising, political advertising etc. • Over-head cables – these show that the country is still among one of the developing countries. Most developed countries have electricity cables running underground, while here they are running about 10m above ground level. Nb: the country is a developing country therefore advanced technology like sensors are not found here. INVISIBLE INFORMATION 1. TRAVEL BEHAVIOUR We can determine the modes used for travel, the different times people travel hence determine the peak and off peak times, the different age groups that travel along this road and this information can be used to improve the transportation service and the traffic levels can be managed. 2. URBAN FUNCTIONS This is associated with the purpose of travel and how people travel. This can help us determine the urban dynamics and also detect urban functionality. By doing so, different urban zones can be classified accordingly e.g work place and shopping place, or both in one area as seen in the attached photograph.
