(upbeat classical music)

- [Michelle] Hello, and
thank you for tuning in

to Connections & Directions.

Our University of Michigan's

Civil and Environmental
Engineering podcast.

My name is Michelle Santillan,

and I am the CEE Marketing
Communications Specialist

and host of this series.

During our podcast, we
are featuring members

of our CEE community and
how their work reflects

our mission of engineers
in service to society.

We will be highlighting
our strategic directions

and our commitment to diversity,
equity, and inclusion.

CEE's five strategic directions

are human habitat experience,
shaping resource flows,

adaptation, automation, and
smart infrastructure finance.

We're here with Zhichen Liu,

a third year PhD student
in transportation studies.

Welcome and thank you for joining us.

- [Zhichen] Yeah, thank
you for having me here.

- [Michelle] How do you
see yourself participating

in CEE's strategic
directions with your research

and how do you see it
fitting in to one of those

or multiple of those five areas?

- [Zhichen] I think in general,

our next generation
transportation programs

is related but not limited
to the automation adaptation

and smart infrastructures.

And we

and my peers,

we are investigating

how to use emerging technologies

such as vehicle automation
and connectivities

to transform traffic
controls, network modeling

and other innovative
shared mobility services.

So personally speaking,
my research is about

how to leverage emerging connected

autonomous vehicle trajectories

and trust to transform the current network

equilibrium analysis framework

and to support better
data informed decisions

for policy makers.

- [Michelle] And specifically, how are you

engaging in this research?
What does the testing

consist of, if you will?

- [Zhichen] When transportation
planning agencies

make decisions about they need to predict

what is the travel, travel demand

in five or 10 years, and
then make decision about

what is the best way to deploy
our roadway infrastructures

and what are the tooling
and pricing strategies

we need to do to reduce
the overall congestions.

When these framework was
initiated like 70 years ago

there was little data availables

about how people travel every days.

So what planners at
that time can do is they

will manually collect some survey datas.

But that is expensive to collect it

and only covers a very sub
samples of the total populations.

But now things becomes different.

We got trajectory datas,
mobile phone datas

and loop detector datas, and
all these datas have abundant

of informations about how
people travel every days.

So my research questions is,
can we somehow leverages this

this kind of new emerging and
multi-source data trust to

better inform the transportation
planning strategies?

So, uh,

more specifically

what I do is I try to
integrate the game theory

perspectives is try to
model the interactions

among all travelers

in this real network.

And I also integrated
some recent development

in machine learning technologies

and try to use the neural
networks to capture better

capture the complicated
behaviors of travelers.

And after I got these kind of

neural network based models

I could try to learn
people's behavior directly

from the empirical trajectory datas.

And after I learning
about people's behaviors

I can go on to do some
policy optimizations to

design the optimal improvement schemes

for the policy makers.

- [Michelle] That's an excellent response.

And how do you envision
everything that you've just

described? How do you see that tying

into CEE's mission of engineers
in service to society?

- [Zhichen] It's, for me,
civil engineering is a field

that directly impact
everyone's everyday lives

and directly changes the
infrastructures around us.

And for me, being a engineer

in service to society is being
a concerned problem solvers.

We need to be concerned with what is going

on on the societies, what
are the emerging technologies

and what are the real needs of people?

And then we being, we
can be a problem solvers

who can use our knowledges
to give better and more

equitable solutions to make
the transportation system

better. Yeah.

- [Michelle] And you
just said more equitable.

How do you see DEI diversity

equity and inclusion
incorporated in our department?

- [Zhichen] I think the DEI
really offers a very welcoming

and inclusive environment
for the communities.

It helps to connect

and support students from a
highly diversified background.

So personally speakings,

I start my first semesters
remotely in China.

I did struggled at the beginnings

because I got the 12 hour time differences

and I got no classmates

around me to have any kind of small talks.

So I remember

at that time our department
have peer mentor programs

which pairs with a remote students

with a more senior master
student or PhD student.

I really appreciate it

because it helps to connect
me with our communities

even though I was doing
everything physical remotely.

And I appreciated my, my peer
mentors who gives me a lot

of suggestions about how
to help me to finally

smoothly transferred
into my graduate life.

Yeah, I really appreciate it.

So, these years I go back
to our peer mentor programs

but this time as a mentor

not mentee. And hopefully what I learned

through my experiences
could be something helpful

for this new coming student.

- [Michelle] Thank you for
giving back in that way.

And do you belong

to the Michigan Student
Transportation Organization?

- [Zhichen] Yes.

- [Michelle] And can
you tell us a little bit

about the work you do in that?

- [Zhichen] So the Michigan Transportation

Student Organizations.

We are a student interest
group that are open

to anyone who have an
interest in transportation.

We aims to connect student
with academic research

and industry opportunities
both on and off campus.

So we have really

three types of event.

The first is Lunch and Learn,
which is a bi-weekly seminars

which offers free food and
features prominent speakers.

We have invited professors
in our own department

our alumnis, as well
as research scientists

from the industry such as general model.

The second line of main activities
we do is technical tours.

We have our regular field
trip towards AM cities

and this month will be
organizing a field trip

towards the Detroit airport.

And additionally we do
support graduate student

and undergraduate student to
attend academic conferences.

So this years we coordinated

with C-CAT a to facilitate
student to participate

the transportation research annual meeting

which is a top tier
conference in our own field.

And I think undergraduate
student will especially benefited

from mentorship match.

We paired every undergraduate student

with an industry representative
at the receptions to

help them better kickstart
their first T R B experience.

- [Michelle] It sounds like you have a lot

of activities planned as an organization.

That's great.

And why did you choose to come
to Michigan's CCE department?

What would you say to
prospective students who

are considering the University
of Michigan in this area?

- [Zhichen] We really
have a strong reputation

and strong faculties.

The our engineering programs
is a top tier programs

in the United States and around the world.

And we got excellent professors.

Professor Ing, Professor Lu,

Professor Masoud and Professor Zhao.

They are all leaders in their own field

and their studies covers a very range

of interesting topics in transportation.

And the second thing that I really enjoyed

at Michigan is we have
a broad curriculums.

We have our professors offering classes

at covering a wide range

of interesting topics in transportation.

And also we are able to take classes

from other department as well.

Personally, I benefited a lot

from the optimization class
from the IOE department

and the machine learning
class from the Ix department.

These kind of broad
curriculums really helps me

to explore my interests

and develop a well-rounded skill
set for my own career goal.

And I do enjoy the
physical life in Ann Arbor

and we had a very engaging community.

- [Michelle] And you were saying that

you're serving as a peer mentor.

If you had one piece of advice
that you could offer to a

an incoming student or
a prospective student

at University of Michigan
CEE, what would that words of

what would that word of
wisdom be or that advice be?

- [Zhichen] For me, it's
just find your passion

and work hard.

You, you may take some
time to find your interest

to find what really fascinates you.

And as long as you find it,
all it takes is just diligence

and persistence to take you
towards a successful careers.

And hopefully what you do can
be beneficial to the societies

and make the general society
better in the same time.

- [Michelle] Thank you
for joining us today.

- [Zhichen] Yeah, thank
you for having me here.

I appreciate it.
