As someone living in an African country I find this headline beyond ridiculous. If this was in Lebanon would we be reading "Asian Bus Routes Redrawn using Cell-Phone Data"?
Interesting as long as you don't ignore a whole demographic (e.g. very poor people without phones).
Cote d'Ivoire is a comparatively prosperous country in West Africa.
Is anyone else slightly annoyed that there is no imagery to show this data on a map? That's all I was actually looking for when I clicked the link. Had a quick look for it and can't see anything. Can anyone else help with a link for the lazy?
Why not "Ivory Coast Bus Routes Redrawn using Cell-Phone Data" ? As someone living in an African country I find this headline beyond ridiculous. If this was in Lebanon would we be reading "Asian Bus Routes Redrawn using Cell-Phone Data"?
Or Vilnius is Europe, yet St. Petersburg isn't.

If you can't afford a second-hand feature phone, you likely can't afford to ride the bus.

"Ivory Coast" is about as descriptive to an American audience as "Africa". I would be shocked if more than a tiny minority of Americans could tell you where the Ivory Coast was outside of "Africa", and I bet many wouldn't even know to place it in Africa, thinking maybe it's in India or SE Asia or something.
It's written like that because Americans don't know and don't really care about African geography.

We'd probably see "Middle-East", the understood name for that region. We might even see "Lebanon" since its close to Israel and Americans like to feel involved in that scene.

Not exactly a high bar it seems...
They talk about 10% time reduction(probably average). Does anybody know more fine grained statistics ?
Hi, I'm from the IBM Research team who worked on this. The reduction is in total system-wide journey times in passenger-minutes (travel time + expected waiting time). The model makes underlying assumptions on how people arrive at stops to do their trips, and how they choose paths through the network. The wait times are therefore related to frequency of services. The statistic is also broken down by each route what ha…
Or more to the point, how correct (or incorrect) were the urban planners in their choice of bus routes?
More information like how large the bus route system had grown since its inception -- for example did it grow organically over time in small growth spurts or was it in larger controlled route expansions/reductions -- would be useful as well.

Are you allowed to share some of the data ? If so:
Does the time includes time to walk to bus station or an estimate?
Is there some histogram of time saved per passenger ? or even something like X% of passengers save a big amount of time ?
Do you have a way to estimate time save by adding routes or alternative transport(like jitneys) before making the change?
Those are interesting, but i also think if some of this data was available(like for example big time saving for some part of the population), this would have better media coverage.
