Abstract — In today’s world, there are lots of people
commuting from place to place. Example: employees going back
home. Students going home from university etc. And lot of times,
people will be commuting via car or bike and there is place to
take a fellow employee along with him to give a ride. But the
problem is there is no easy way to know how many people a
person can take and co-ordination is a huge issue that there is no
effort by people to help each other by giving a lift and more over
this saves the environment in reducing fuel usage, reduces traffic
with fewer vehicles etc. The Carpool is an android application
which will provide the advanced searching techniques and
provide most relevant results for the carpooling in the city. This
will be help full in easy way Carpooling reduces the costs
involved in repetitive or long distance driving by sharing cars,
sharing rental charges, or paying the main car owner. Some
countries have introduced high-occupancy vehicle (HOV) lanes
to encourage carpooling and use of public transport, to combat
rising traffic congestion [1].

INTRODUCTION
In recent years, the problems of global warming and the
energy crisis have aroused widespread public concern. One
recommended solution for reducing the harmful factors
leading to such problems is carpooling. This type of
transportation service could make a big difference if
organized on a large scale by government or big companies,
particularly large corporations with many branches or subcompanies.
Carpooling schemes are designed to encourage
commuters to share travel expenses and resources with
colleagues. Carpooling (also known as car-sharing, ridesharing,
lift-sharing), is the shared use of a car by the driver
and one or more passengers, usually for commuting.
Carpooling arrangements and schemes involve varying
degrees of formality and regularity.

Formal carpool projects have been around in a structured
form since the mid-1970s [1]. Long-term carpooling is
defined as the sharing of a private vehicle by several
individuals who follow a semi-common route between
different points of origin and destination (OD) during a
specific period. In practice, a participant can request to share
the same trip with his/her friends, in which case they are
treated as a participant group with the same OD and travel
route/schedule. The results of such an action are the
following:
1) Reduction in the number of vehicles on the route;
2) Reduction in expenses for gas;
3) Reduction in energy consumption (CO2 emissions)
and Pollution;
4) Provision of social connections in an increasingly
Disconnected society [2].

The Dynamic Carpooling is more complicated than longterm/
daily many-to-one or one-to-many car pooling
problems. An efficient plan for the Dynamic Carpooling
may require matching participant groups to a car on a semi
common route or assigning a participant group to different
cars on different days. It is very difficult to simultaneously
and optimally determine every participant group’s role
(driver group or passenger group), driver group schedules,
and passenger group deliveries, as well as to suitably match
several participant groups in a car while still keeping in
mind fairness considerations. This process involves
complicated movements of driver groups (or vehicles) and
passenger groups in both time and space,
