The focus of this research project was to analyze and collect travel trajectories to
different travel modes and identify ways to reduce it. We collected trajectory data
and translated it into energy consumption to determine if shared ride modes were
amount of reduced carbon footprints. We also researched issues associated with r
routes, safety concerns, time costs, and social discomfort. Ridesharing is a possibl
amount of carbon emissions in our growing communities.
While our society struggles with congestion, pollution, energy
efficiencies and intensive economies, many private and public vehicles
are still barely occupied. Several factors are thought to impede the use
of ridesharing, including lack of trust amongst co-passengers, loss of
flexibility, safety risks, and the availability of dynamic route matching
algorithms to minimize queues and total travel time. Lessons
concerning our environment and awareness of our carbon footprint
are designed to engage students to calculate their own emissions and
develop possible transportation solutions, creating awareness of the
need for emission reduction through ridesharing modes.

Everyday people travel extra miles in our vehicles running errands,
going to and from work and school, or vacations. Nearly 51% of our
yearly CO, emissions comes from transportation modes. The
average vehicle in the US contains i.6 persons per vehicle mile and
travels almost 35 miles per day. Every mile you travel can be
converted into energy consumption which alters the carbon
footprint of individuals, our country, and our planet. Our vehicles
emit 19 pounds of CO, for each gallon of gas consumed. Below is a
table provided by the US Department of Energy showing how fuel

Figure i depicts a rideshare opportunity on a RET fieldtrip to the
Water Research Station near Denton, Texas. The purple color
shows the route taken to the station. Fourteen people were
transported to the research station in 4 different vehicles.
We emitted only about 4o pounds of CO, instead of the 140
pounds of CO, that could have been expended had everyone
taken individual vehicles.
