Dear Huston,
Many of us have
always known black spots to be very dangerous spots on our roads. Technically, I've
always doubted the methodology used to declare these spots "black". I think the causes of accidents should be more weighty than just the frequency of accidents in declaring black spots. In fact, the frequency of accidents should be tied to the causes related to the uniqueness of the spot like having blind corners, fog, etc. Look at it this way, if point 'A' has 7 accidents in a week due to drunken driving near a market at a junction and point 'B' has 3 accidents in a period of 3 months due to hardly noticeable poor engineering of the road by contractors hired by the government, which area do you think will be declared a black spot? I have a feeling some spots are largely declared black just to manage emotions of the local community after a fatal accident has happened and a community demonstration is held, and the police together with local administration erect mountainous bumps and declare the spot as black, then it goes down to records as black. Sometimes, a place on the road can be too scary I agree, because of the blurred vision due to fog or meanders of the road. All these has nothing to do with frequency of accidents. My point is, if the methodology that was used to declare these black spots had something to do with frequency of accidents tied to the uniqueness of the area then "whoever" came up with this list should provide you with data and also find out the causes of the accident. If not, you'd rather just find data on frequency of road accidents on Kenyan roads and do your own assessment of black spots.
Alternatively,
it's highly-likely that road accidents that happened near these so called "black
spots" were reported to the nearby police stations as required by
law. However, since you have the list, call, walk into traffic departments, use your contacts, hack
into systems :) visit ministries and government agencies if you really need these
data. Seems nobody in our circle has organized this data into spreadsheet.
Lastly, I wish you good luck!
