good afternoon today I will speak to you about
about
about doing in mobility and particularly in
doing in mobility and particularly in
doing in mobility and particularly in developing cities so let me give a brief
developing cities so let me give a brief
developing cities so let me give a brief background about how our came to be when
background about how our came to be when
background about how our came to be when you look at traffic in developing cities
you look at traffic in developing cities
you look at traffic in developing cities we see a lot of interesting phenomena
we see a lot of interesting phenomena
we see a lot of interesting phenomena the first the first of all being
the first the first of all being
the first the first of all being governments are are faced with
governments are are faced with
governments are are faced with challenges in terms of understanding
challenges in terms of understanding
challenges in terms of understanding their road infrastructure what this
their road infrastructure what this
their road infrastructure what this means is if a government for example
means is if a government for example
means is if a government for example once you know how their roads are it’s
once you know how their roads are it’s
once you know how their roads are it’s very difficult because most of the
very difficult because most of the
very difficult because most of the solutions you will find out there to
solutions you will find out there to
solutions you will find out there to help you understand about your roads are
help you understand about your roads are
help you understand about your roads are very costly and therefore prohibitive
very costly and therefore prohibitive
very costly and therefore prohibitive for developing cities such as Nairobi to
for developing cities such as Nairobi to
for developing cities such as Nairobi to acquire now at the same time this
acquire now at the same time this
acquire now at the same time this governments have responsibility to
governments have responsibility to
governments have responsibility to deliver service to their citizens so
deliver service to their citizens so
deliver service to their citizens so some interesting facts about nairobi for
some interesting facts about nairobi for
some interesting facts about nairobi for instance which is a developing city up
instance which is a developing city up
instance which is a developing city up to 1 million u.s. dollars is lost every
to 1 million u.s. dollars is lost every
to 1 million u.s. dollars is lost every day due to traffic congestion we also
day due to traffic congestion we also
day due to traffic congestion we also see a lot of interesting phenomena such
see a lot of interesting phenomena such
see a lot of interesting phenomena such as traffic becoming unbearable whenever
as traffic becoming unbearable whenever
as traffic becoming unbearable whenever trains and also in a in a in a survey
trains and also in a in a in a survey
trains and also in a in a in a survey done by IBM in 2010 IBM was ranked the
done by IBM in 2010 IBM was ranked the
done by IBM in 2010 IBM was ranked the 4th most painful commute city in the
4th most painful commute city in the
4th most painful commute city in the world why do we even care about traffic
world why do we even care about traffic
world why do we even care about traffic in developing cities for example I will
in developing cities for example I will
in developing cities for example I will have you know that Africa accounts for
have you know that Africa accounts for
have you know that Africa accounts for over 90% of the world’s traffic
over 90% of the world’s traffic
over 90% of the world’s traffic accidents yet Africa has under five
accidents yet Africa has under five
accidents yet Africa has under five percent of these vehicles why is that so
percent of these vehicles why is that so
percent of these vehicles why is that so for us as researchers we tend to answer
for us as researchers we tend to answer
for us as researchers we tend to answer these difficult questions and the
these difficult questions and the
these difficult questions and the question for us is how or what are the
question for us is how or what are the
question for us is how or what are the infrastructural and behavioral factors
infrastructural and behavioral factors
infrastructural and behavioral factors that affect how traffic culminates in a
that affect how traffic culminates in a
that affect how traffic culminates in a developing city and we do this using a
developing city and we do this using a
developing city and we do this using a smart phone and this was an obvious
smart phone and this was an obvious
smart phone and this was an obvious choice for us because luckily for us we
choice for us because luckily for us we
choice for us because luckily for us we work in an environment where there are
work in an environment where there are
work in an environment where there are more phones than there are people
so we have an adapted smartphone mounted
so we have an adapted smartphone mounted onto a vehicle and as the vehicle moves
onto a vehicle and as the vehicle moves
onto a vehicle and as the vehicle moves on the roads of Nairobi we’re able to
on the roads of Nairobi we’re able to
on the roads of Nairobi we’re able to use the accelerometer to pick up the
use the accelerometer to pick up the
use the accelerometer to pick up the top-down vibrations and this tells us
top-down vibrations and this tells us
top-down vibrations and this tells us how the vehicle is interacting in the
how the vehicle is interacting in the
how the vehicle is interacting in the road surface we also use the gyroscope
road surface we also use the gyroscope
road surface we also use the gyroscope to pick up the circular motion and this
to pick up the circular motion and this
to pick up the circular motion and this tells us how drivers are maneuvering
tells us how drivers are maneuvering
tells us how drivers are maneuvering around these traffic obstacles such as
around these traffic obstacles such as
around these traffic obstacles such as potholes and speed mom’s now I brought
potholes and speed mom’s now I brought
potholes and speed mom’s now I brought that a small demo for you today and in
that a small demo for you today and in
that a small demo for you today and in this demo we show demos don’t walk when
this demo we show demos don’t walk when
this demo we show demos don’t walk when you want them to walk but on the Left I
you want them to walk but on the Left I
you want them to walk but on the Left I show you the data that’s coming from the
show you the data that’s coming from the
show you the data that’s coming from the accelerometer and the gyroscope and on
accelerometer and the gyroscope and on
accelerometer and the gyroscope and on the Left I show you real-time detection
the Left I show you real-time detection
the Left I show you real-time detection of the potholes and speed bumps that are
of the potholes and speed bumps that are
of the potholes and speed bumps that are on this truck so sometime last year we
on this truck so sometime last year we
on this truck so sometime last year we walked with Nairobi City County an
walked with Nairobi City County an
walked with Nairobi City County an install 10 of these devices into their

garbage collection trucks so garbage
garbage collection trucks so garbage collection being because they will go to
collection being because they will go to
collection being because they will go to every part of the city and for the
every part of the city and for the
every part of the city and for the period between for the period between
period between for the period between
period between for the period between April and August of last year we’ve been
April and August of last year we’ve been
April and August of last year we’ve been collecting this data about the roads in
collecting this data about the roads in
collecting this data about the roads in Nairobi and we built a digital map of
Nairobi and we built a digital map of
Nairobi and we built a digital map of where all the potholes are and where all
where all the potholes are and where all
where all the potholes are and where all the speed bumps are and from this map
the speed bumps are and from this map
the speed bumps are and from this map we’ve gone ahead to build applications
we’ve gone ahead to build applications
we’ve gone ahead to build applications that help drivers who are driving in
that help drivers who are driving in
that help drivers who are driving in roads such as this one and what I’m
roads such as this one and what I’m
roads such as this one and what I’m showing you right now is a sample of
showing you right now is a sample of
showing you right now is a sample of that application as you are driving in a
that application as you are driving in a
that application as you are driving in a Robbie

Robbie repair is a seed but ahead please slow
repair is a seed but ahead please slow
repair is a seed but ahead please slow down
down
down we warned you about oncoming traffic
we warned you about oncoming traffic
we warned you about oncoming traffic obstacles and at the same time we show
obstacles and at the same time we show
obstacles and at the same time we show you a score that tells you how well
you a score that tells you how well
you a score that tells you how well you’re driving or how you’re maneuvering
you’re driving or how you’re maneuvering
you’re driving or how you’re maneuvering these modules and speed bumps there is a
these modules and speed bumps there is a
these modules and speed bumps there is a module
can it can come in very handy at night
can it can come in very handy at night there is a speed bump ahead please so
there is a speed bump ahead please so
there is a speed bump ahead please so down there is a porthole ahead please
down there is a porthole ahead please
down there is a porthole ahead please swerve right so with such data collected
swerve right so with such data collected
swerve right so with such data collected from mere mobile phones been able to
from mere mobile phones been able to
from mere mobile phones been able to build a digital map of Nairobi and
build a digital map of Nairobi and
build a digital map of Nairobi and showed how we can use technology that we
showed how we can use technology that we
showed how we can use technology that we use every day and many of you may not
use every day and many of you may not
use every day and many of you may not know this but your smartphone contains a
know this but your smartphone contains a
know this but your smartphone contains a large sensor suite of up to 14 different
large sensor suite of up to 14 different
large sensor suite of up to 14 different sensors which you can use to tell you a
sensors which you can use to tell you a
sensors which you can use to tell you a lot about for example the roads and the
lot about for example the roads and the
lot about for example the roads and the rooms you’re in we see this as a great
rooms you’re in we see this as a great
rooms you’re in we see this as a great example of how Africa can use prevalent
example of how Africa can use prevalent
example of how Africa can use prevalent technologies such as mobile phones to
technologies such as mobile phones to
technologies such as mobile phones to help to help alleviate the problems that
help to help alleviate the problems that
