An Investigation into the Traffic Flow Problems on Jogoo Road, Nairobi

ABSTRACT

Efficient mobility is a pre-requisite to effective socio-economic performance of a nation. Given that cities are increasingly seen as the engines of economic growth, and that this can only be realized with a well-performing urban transport system, any drawback to this must be adequately dealt with. Good transport plays an important role in confronting the multiple urban development challenges of poverty reduction, productivity enhancement, employment provision, infrastructure provision and protection of the environment  Jogoo road is one of the major corridors in Nairobi that experiences serious traffic congestions daily. In an attempt to effectively respond to this drawback, very many initiatives have been

sought over the years along this road but much has not been achieved. First the road, being a once one carriage-way corridor was first expanded in 1963 and even later dualled to accommodate more vehicles. Secondly, foot bridges were built to help the crossing pedestrians who initially were an impediment to the free flow of vehicles along the road. Thirdly, there has been the introduction of 25-60 seater public vehicles in an attempt to phase out the matatus, which are conceived to be a major contributor to the traffic flow problems (G.o.K, 2009). Fourth, vehicles along it have also been restricted to interchange at Muthurwa. However, none of these has offered a lasting solution.

This study was therefore set to investigate and analyze the factors that contribute to traffic  congestion on this road and their consequences, with the view to propose appropriate intervention measures to this problem. The objectives of this study were to establish the traffic flow conditions that occur on Jogoo road; to examine the factors which contribute to traffic congestion on Jogoo road; to examine the effects of traffic congestion along Jogoo road; and to propose general and land use planning oriented solutions to the traffic flow problems on Jogoo road.

The major findings of the study were that the causes of traffic congestion on Jogoo road included too many low capacity vehicles, poor management by traffic police, roundabouts, indisciplined drivers, inadequate road space among others. The effects of the congestion comprised of time  wastage/lateness, usage of too much fuel, air and noise pollution, discomfort while inside the vehicle, risk of accidents, reduced financial returns for businesses and vehicle operators and nuisance in estates and business areas where motorists traversed as they escaped jam on the main roads.

Some of the recommendations in response to these issues included carrying out frequent studies to assess the changing demand for transport facilities due to the pertinent urbanization trends, integrating of land use and transportation planning; efficiently designing road networks, with adequate provision of NMT facilities; efficiently instituting traffic management authorities and tools; and promoting the state of public transportation among others.
