TEAM LEADER: In a timed
scheduled of
“green”, “yellow”, and “red” lights
control the flow of traffic and
interaction between motorists
and pedestrians.
Members of team that make
up predominance. Motorists
utilize signals as direction; sign
of whether it is safe to
continue or contrastingly stop.
Pedestrians are newer, yet
essential team members. In
respect to crosswalks, pedestrians
also follow light signals in order to
know when to cross, when not to
cross, and how much time they
have to do so.
The controller was more
predominant in the early stages of
the team in that now most are
mechanically controlled and on a
set time schedule. Few still exist.
THE TEAM MODELThe traffic system although hierarchical in
physical structure, functions cyclically.

WHY IT’S EFFICIENT
• Although there are team “leaders” v. “members”, the group
utilizes an open communication that allows any member to
step in when problems arise. This leads to a more rapid
problem solving process and moreover, better functioning
team.
SUPPORT
• From interviews conducted with the human components of the
system (i.e. pedestrians and motorists), most people believe
that the traffic lights system works adequately. The traffic
system team has created a sense of trust within its members
as well as other independent users.
PROBLEMS
• Most pedestrians disobey traffic light indications
• Members take cues from traffic and cross when they
think it’s safe
• Lights can signal green to an empty street causing
delays for other system participants
• Some motorists do not respect the yellow signal
• Motorist attempt to find loop holes in system thus
benefiting their traffic experience
• A lack of feedback triggers more problems
• System malfunctions can be quite timely to solve thus
creating opportunities for possible accidents and
congestion
• A presented difficulty in problem solving in result of
many, various constituencies; all of who want their
needs prioritized
conclusion
CURRENT MODELThis team model is very efficient despite its complexity. It
achieves effectiveness through collaboration, willingness to adapt, and open communication.
effectively coordinates traffic
adapts to users and working environments; builds trust
solves problems in timely manner
SUGGESTIONSDespite a proven difficulty in attending to all suggestions, the
team is in need of additional fluidity in communication. The further acknowledgement of all external suggestions for improvement would be highly beneficial.

OUR TEAM DYNAMIC
• Assessment: We first made sure to understand the
assignment and then come up with an idea we were both
interested in and agreed upon.
• Communication: Just like the team we observed, we were
very efficient in that we made sure to communicate with each
other constantly. We set goals, planned ahead, and most
importantly scheduled our allotted time given.
• Execution: In executing our project, we were successful in
splitting up work equally through playing upon each of our
individual strengths. A cohesive execution was also possible in
that we observed, discussed, and analyzed together and in
person.
