Yellow minibuses, known as danfos, are by far the most popular mode of transport into and around the city of Lagos. Danfos and their drivers have been found to be the main reasons for congestion in the cities, because they are absolutely everywhere. Over 75,000 of these yellow striped Volkswagen buses were on the roads in 2008 (Otunola 4). Because they are small, they cannot carry as many passengers (only 12-14 sitting down) as some of the bigger modes of transport. As such, they make up most of the traffic (69% of all motorized trips) on Lagos roads (Otunola 4).

Danfos are notorious for their lack of safety standards and poor service. In 2008, there were around 2-3 accidents per week involving danfos (Otunola 4). This can be attributed to the frequent traffic violations by drivers in Lagos. These traffic violations and subsequent accidents are the reasons for a lot of the back up and congestion on the roads of Lagos.

For these reasons, there are plans to phase out danfos and replace them with government run buses, though these plans have been met with some mixed responses. At this point, danfos seem no closer to being scrapped than ever, and they are still a part of daily life for most Lagosians. 

This image clearly represents the severity of the traffic situation in Lagos. This photo of the Idumota Market on Lagos Island was taken by Robin Hammond and published in the January 2015 issue of National Geographic magazine. Congestion like the above is a matter of daily life for commuters in Lagos, and the danfo buses shown above are the primary mode of transport for those without private vehicles. The lack or organization is really apparent; there is seemingly no system for how these buses move around this market, and this lack of organization directly contributes to the congestion.
