hello Armand,
our transportation is good,the network is developed since it gets you anywhere you may want to go to but i cant exactly say its very developed since its limited to road transport.
we have buses, taxis'(mini-buses) boda bodas'(motor-cycles) as you will get to know and the special hire care,(that you call taxis in your country). these you can find anywhere and are quite safe as long as get them from well known places and take some precaution like making sure you get into a taxi or bus with lots of people so as not to be mugged, taking boda bodas from there stages as they are registered,same as special hires. but i can guarantee comfort.
