chapter{Introduction}
label{chap:introduction}
section{Motivation}
%The motivation
In modern society where there are increasing number
of cars per day commuting
on roads,
traffic congestion has become more severe.
It is expected that traffic congestion will be further exacerbated
as population continues growing.
According to ``Global Status Report on Road Safety''
cite{WHO2015},
over one million people were killed
and over fifty million were injured
in road traffic crashes
in just one year (2013).
In addition,
over seventy-five percent
of all road traffic deaths occur
in low- or middle-income countries cite{WHO2015}.
Hence,
it has become imperative
to alleviate traffic congestion
and improve road safety.
A promising way
to address these issues
is using connected vehicles.
Connected vehicle technology
allows vehicles
to communicate with each other cite{NHTSA2015}
and thereby enables vehicles
to make decisions based on other vehicles' status.
Such inter-vehicle communication can reduce congestion by improving traffic flow,
and can also increase road safety by avoiding collisions.
% The current state-of-the-art
There are several state-of-the-art methods
for utilizing connected vehicle technology.
The Connected Vehicle Pilot Deployment Program cite{NHTSA2015}
implemented by U.S. Federal Highway Administration (FHWA)
is one example.
This program has been conducted in ten pilot sites across U.S. since November~2012.
It aims at demonstrating how connected vehicle technology can improve safety,
mobility,
and environmental impacts.
Another example is Cooperative Adaptive Cruise Control (CACC) cite{CACC2009}.
CACC aims at improving highway capacity by decreasing headways between vehicles.
As headways decrease,
more vehicles fit into a given length of highway,
which increases highway capacity.
% Our work
The main purpose of our work
is providing new knowledge about how connected vehicles affect highway capacity.
To this end,
we conduct simulation experiments using SUMO (Simulation Of Urban MObility) cite{SUMO2007},
a microscopic traffic simulation package.
We implement CACC in SUMO using its TraCI interface cite{TraCI2009},
which allows controlling simulated vehicles from outside SUMO.
Our simulation experiments show that CACC can indeed increase highway capacity;
however,
it also shows that there is an optimal headway,
whereby further decreasing headways beyond this optimal point does not lead to increasing capacity.
Our work differs from previous studies
in two ways:
First,
we investigate effects of CACC under various conditions;
specifically,
we consider various combinations
of percentages (%) of CACC-equipped vehicles,
percentage (%) of vehicles having limited sensing range,
and maximum acceleration/deceleration capabilities.
Secondly,
our work provides more quantitative results than previous studies;
for example,
previous studies have shown that CACC improves highway capacity by decreasing headways between vehicles cite{CACC2009},
but our work shows exactly how much improvement can be achieved.
% Organization
This chapter is organized as follows:
Section~ref{sec:background} gives background information about connected vehicle technology.
Section~ref{sec:related_work} describes related works about CACC.
Section~ref{sec:methodology} introduces our methodology.
Section~ref{sec:experiments} presents our experiments.
Section~ref{sec:results} describes our results.
Section~ref{sec:conclusion} concludes this chapter.
section{Background}
label{sec:background}
This section provides background information about connected vehicle technology.
subsection{Connected Vehicle Technology}
Connected vehicle technology allows vehicles
to communicate with each other via wireless communication networks.
By communicating with each other,
vehicles can share information about themselves (e.g., location),
the surrounding environment (e.g., road condition),
and events (e.g., accidents).
This shared information helps vehicles make better decisions cite{NHTSA2015}.
For example,
if one vehicle suddenly brakes hard due to an obstacle ahead,
other nearby vehicles will know about this situation beforehand thanks to connected vehicle technology.
Then these other vehicles will be able to avoid colliding with each other even before seeing this obstacle.
% Some examples
The following are some examples showing how connected vehicle technology can improve road safety:
begin{enumerate}
item Forward Collision Warning (FCW)
noindent - FCW warns drivers when they are driving too close to other vehicles ahead cite{FCW2010}.
Without FCW,
a driver might collide with another vehicle ahead due simply because he/she did not notice it was there;
however,
FCW notifies drivers when they are approaching another vehicle too closely so they will slow down before colliding.
With connected vehicle technology,
vehicles do not need drivers' intervention;
instead,
they communicate with each other directly;
this enables them not only notifying drivers but also applying brakes automatically if necessary.
item Intersection Movement Assist (IMA)
noindent - IMA warns drivers if they drive through intersections unsafely cite{IMA2010}.
Similarly as FCW,
it notifies drivers when they should slow down before approaching intersections unsafely;
however,
it does so by considering both vehicles ahead emph{and} cross traffic simultaneously.
item Emergency Electronic Brake Light (EEBL)
noindent - EEBL alerts drivers behind when another vehicle applies brakes hard cite{EEBL2010}.
In general braking lights notify drivers behind when another vehicle applies brakes;
however,
braking lights turn off after some time even if another vehicle continues applying brakes hard;
this might confuse drivers behind because they might think another vehicle stops applying brakes even though it does not stop yet;
this confusion may lead them into collisions;
EEBL addresses this issue by blinking braking lights continuously when another vehicle applies brakes hard so that drivers behind will never be confused into thinking another vehicle stops applying brakes even though it does not stop yet.
Like FCW,
vehicles do not need drivers' intervention;
such communication between vehicles enables them applying brakes automatically if necessary.
item Electronic Lane Keeping System (eLKS)
noindent - eLKS warns drivers if they drive out-of-lane unintentionally cite{eLKS2010}.
It notifies drivers when they should steer back into their lanes before running out-of-lane unintentionally;
this reduces lane departure collisions significantly.
Similarly as FCW/IMA/EEBL,
eLKS does not need drivers' intervention;
it communicates directly between vehicles so that it notifies drivers emph{and} steers back into lanes automatically if necessary.
end{enumerate}
These examples show that connected vehicle technology can improve road safety by reducing collisions between vehicles;
it also improves road safety by reducing collisions between vehicles emph{and} pedestrians/cyclists by notifying drivers/pedestrians/cyclists if necessary;
it even improves road safety by notifying pedestrians/cyclists themselves if necessary.
% Other benefits
Other than improving road safety,
connected vehicle technology also improves mobility by reducing congestion cite{nhtsa-2014};
it also reduces environmental impacts by reducing fuel consumption/emissions cite{nhtsa-2014}.
This section has introduced background information about connected vehicle technology;
the next section describes related works about CACC.
subsection*{}
As mentioned earlier in Section~ref{sec:motivation},
one way utilizing connected vehicle technology is Cooperative Adaptive Cruise Control (CACC) cite{CACC2009}.
This section describes background information about CACC.
% What CACC is
CACC aims at improving highway capacity by decreasing headways between vehicles.
As headways decrease,
more vehicles fit into a given length of highway,
which increases highway capacity.
% How CACC works
CACC works as follows:
First,
a lead vehicle decides its acceleration/deceleration based on some criteria.
Then,
following vehicles decide their acceleration/deceleration based on their lead vehicles'
acceleration/deceleration,
their own status (e.g., speed),
and sometimes their following neighbors' status.
Figure~ref{fig:cacc_example} shows an example illustrating how CACC works.

An example illustrating how Cooperative Adaptive Cruise Control (CACC) works.
Here,
three leading cars control three following cars respectively.
Each leading car decides its acceleration/deceleration based on some criteria;
then,
each following car decides its acceleration/deceleration based on its lead car's acceleration/deceleration,
its own status (e.g., speed),
and sometimes its following neighbor's status.
Figure taken from ``Cooperative Adaptive Cruise Control'' cite[CACCTechReport2009][]{CACC2009}. }

label{fig:cacc_example}
end{figure}
% Some examples
The following are some examples showing how CACC improves highway capacity:
For example,
one study showed that increasing percentage (%) of CACC-equipped vehicles from zero (%) to twenty (%) increased highway capacity by twenty-five (%) under certain conditions; moreover,
it showed that increasing percentage (%) from twenty (%) to forty (%) increased it further by fifteen (%) under these conditions cite[Chapters~6--8][]{HagiwaraPhDThesis2015}.
These examples show that CACC improves highway capacity by decreasing headways between vehicles; however,
it remains unknown exactly how much improvement it achieves; furthermore,
there may exist an optimal headway whereby further decreasing headways beyond this optimal point does not lead to increasing capacity.
The next section describes related works about CACC; finally,
Section~ref{sec:conclusion} concludes this chapter.
