Management of traffic circulation in Nairobi City, a case study of upper hill area
Traffic circulation in Upper Hill area of Nairobi City has been an issue of major concern to road users, planners, policy makers, employers, investors, the police department and many other stakeholders for a long time. The spillover of development and functionality of the CBD to the Hill Area in the last few years has seen densification of development of high rise buildings accommodating mainly office and commercial space as well as residential units. The population of both human and vehicular traffic in Upper Hill has increased tremendously and yet the infrastructure including the road network has remained almost the same. The study examined the traffic circulation characteristics in the area, the existing policy, regulatory and institutional mechanisms for the management of traffic circulation and evaluated the effectiveness of the existing policies regulatory and institutional mechanisms in the management of traffic circulation. The study found that inadequate road capacity, careless driving accidents, ineffective public transport and its poor network integration, lack of parking facilities and poor planning rules in the area as some of the factors contributing to the poor traffic circulation in the area. It has also been established from the study that existing mechanisms and policies on traffic circulation are not effective in the area. The study therefore recommends that in order to alleviate the deteriorating traffic circulation in the study area, measures such as strict enforcement of traffic rules by the police and City authorities should be given priority. The procedures for reporting accidents and non-conformities should be streamlined. The roads within the study area should be redesigned in such a way as to convert some roads such as Ragati, Upper Hill and Lower Hill to one way. Parking on, and /or a long, narrow roads without adequate road reserves should be restricted. The roads should be widened as per the proposals that have already been put in place by the planning authorities to offer off-street parking and improve road capacity. The land use zoning plan for the area which is already approved should be implemented and those occupying part of the land earmarked for road widening asked to surrender them.
