Jamani haya matuta au speed humps haziondoi ajali bali zinazidisha ajali. Pia ni matumizi mabaya ya fedha za umma.Yesuuuuu...Hivi suca si kuna matuta pale? Kuna nini kimara??????
Think this way, you put more humps and bumps on the highway, you reduce speed during crossing those humps/bumps but someone has to drive faster just after crossing the humps/bumps to catch up with time, then what happens? an accident. Again you spot where the accident happened and you put another bump, etc,etc, how many bumps are you going to put on the road? Some bumps/humps has no warning signs and hence for a new driver to that route can actually lead to another accident if crossed unexptedly at high speed.
If the roads are made with clear signs at correct locations enough to warn, and people (drivers, pedestrians, cyclists,etc) who do not respect signs are fined accordingly, it may reduce the number of accidents on the road but more importantly the education of both drivers and other road users is very important in addressing road accidents.
