  4. PROJECT BACKGROUND • The human population in Nairobi county is increasing at a very fast pace. • This is leading to a strain of the available infrastructure e.g. water and transport • The traffic congestion on many roads within the county is a clear indication of lack of an efficient transport system. • The government needs to put measures in place to reduce the traffic jams. • Use of Geospatial technology will provide a solution for this. 3 joewachiye@gmail.com

  5. PROBLEM STATEMENT • The current commuter train operates on a rail line that was set up mainly for ferrying cargo. • This implies that the commuter train services are not effectively and efficiently delivered to the Nairobi County dwellers. • The need to assess the suitability of the current commuter railway network is the basis of this project. 4 joewachiye@gmail.com

  6. OBJECTIVES General Objective To design a Geodatabase of the current commuter railway line and railway stations, that will assist in the storage and maintenance of data and information 5 joewachiye@gmail.com

  7. Specific Objectives To map all the existing railway stations within the area of study To map the existing commuter railway line within the study area To propose railway lines to suitable locations 6

  8. METHODOLOGY 7

  9. ANALYSIS • The railway stations were buffered with a 5km buffer distance, their Euclidean distance calculated, then reclassified. • The railway line was also buffered with a 5km buffer distance, its Euclidean distance calculated and then reclassified. • DTM was used to generate the slope map for the study area. The slope map was then reclassified. • Land use data set was converted to raster format then reclassified. • Population was also converted to raster then reclassified 8 joewachiye@gmail.com

  10. ANALYSIS Contd’ • All the reclassified data sets had 6 uniform classes and were weighted. The result was a suitability map 9 joewachiye@gmail.com

  11. RESULTS Reclassified slope 10 joewachiye@gmail.com

  21. New railway line • A new railway line could not be set up since the ground is already covered with buildings. • It is un economical to the government and the republic in general to demolish the buildings in order to set up a new railway line • MRTs running on the road reserves is the solution. 20 joewachiye@gmail.com

  22. PROPOSED MRTs CORRIDORS 21 joewachiye@gmail.com

  23. CONCLUSION • A suitable railway line could not be set up due to human developments in the region. • The study area is small, which implies that it can only support a radial pattern of a new commuter railway. Feeder roads to stations then need to be improved. • The MRTs proposal was in line with the Nairobi Urban Master plan 2013, as prepared by JICA. 22 joewachiye@gmail.com

  24. RECOMMENDATIONS • The government needs to improve the current commuter train, in terms of speed and capacity. • A new standard gauge railway t be set up besides the current one. • Set up the proposed MRTs corridors. • Extend the current commuter services to satellite counties e.g Thika, Kiambu, Machakos and Kajiado, since they will attract more people in an effort to decongest the county. • Further research. 23 joewachiye@gmail.com
