Fieldwork Question: Which are more effective in promoting vehicular traffic flow in Nairobi: roundabouts or unregulated intersections?

A person who works in the city centre coming from outside of Nairobi, therefore, has a very long trip to work, which is mostly spent sitting in their car, wishing they had woken up a little earlier to escape the mess. Nairobi?s poorly designed infrastructure and lack of cooperation between politicians, largely because of corruption, only adds to the chaos. Drawn from the syllabus section: Urban Environments, the field study compares various measures of congestion at two types of intersections, which are common in Nairobi, roundabouts and unregulated intersections, in order to establish their effectiveness.
