UN-Habitat welcomes the conference on “Driving towards Sustainable Urban Transport Systems in Africa” to be held in Nairobi from April 24-25. Given the increasing traffic congestion in cities, this is indeed a very timely topic that affects citizens and businesses and raises many relevant issues some of which are not self-evident.
A study conducted by UN-Habitat, an analysis of the road pattern in Nairobi based on satellite images, shows first that Nairobi has currently 23 different street patterns in its urbanised areas. One reason for traffic-congestion is that streets are not fully connected to their vicinities.
