Abstract - Taxi-sharing system is developed using mobile
cloud architecture. This project usetemporalindexing method
to locate the active user position and searching algorithm to
track the driver and user positions and scheduling algorithm
to schedule the user requests. Proposed taxi riders and drivers
can access same mobile app. Passengers submit real time ride
request using the same app. On receiving a new request, the
server will first search for the taxi with minimal the travel
distance and check with existing booked details .if any match
found based on the user request then the list of available taxis
will show to users .user can select any taxi by touching thetaxi
details .once, user touch the driverdetails, theuserrequest will
send to driver. If drivers select agree to pick up a new
passenger, then the total amount will get divided and refund
among them. There is no direct cost for public agencies, since
the systems arrange ridesharing payments between drivers
and riders.

1. INTRODUCTION
Taxi is an important transportation mode between public
And private transportations, delivering millions of
passengers to different locations in urban areas. However,
taxi demands are usually much higher than the number of
taxis in peak hours of major cities, resulting in that many
people spend a long time on roadsides before getting a taxi.
Increasing the number of taxis seems an obvious solution.
But it brings some negative effects, e.g., causing additional
traffic on the road surface and more energy consumption,
and decreasing taxi driver’s income .
To address this issue, Real-time ridesharing (also called
dynamic, or instant ridesharing)isanautomatedsystemthat
matches drivers and riders on very short notice or even en-
route,differing fromformal ridesharingbynotrequiringpre-
planning or recurrence. Though most commuters prefer to
pre-arrange commutes at least the night before, real-time
ridesharing promotes taxis regardless of the time available
for planning.
Formerly, people used hand signals for getting taxi
Ride’s by the side of roads. In peak times, they had to wait
for long hours to get a free taxi. But after the Introduction of
mobile applications rider use one of many private services
through an application on their smartphone that
automatically pairs them with a driver, this problem was
addressed to some extent. It not only helped the road side
passengers but also arrangedhomepickups. Whether itmay
be an instant ride requestor a preplannedrequest,obviously
the mobile applications made a huge impact on the taxi
passengers. But the service providers still faced some
difficulties in searching nearby taxi'sasthelocationofa taxis
available was highly volatile and it is was not determined by
according to the passenger’s request instantly. Taxi sharing
is a technique in which many people share one vehicle
during real time rides. It is highly encouraged because it is
said to a renewable andaneco-friendlyway,becausesharing
ones ride with others can reduce carbon emissions, road
traffic congest ions, fuel intake and the need for parking
spaces. Ride sharing is an economical way in which both the
passengers and the drivers gets mutually benefited. The
major technologies which are Commonly used in real time
ride sharing are GPS(Global Positioning System) navigation
devices and smart phones that acceptstaxipassengers’real-
time ride requests sent from smart phones and schedules
proper taxis to pick up them via taxi-sharing with time,
capacity, and monetary constraints (the monetary
constraints guarantee that passengers pay less and drivers
earn more compared with no taxi-sharing is used).
2. PROBLEM STATEMENT
Taxi is an important transportation mode between
commercial and private transportation, delivering millions
of passengers to different locationsinurbanareas.However,
the number of taxi is much less than its demand in peak
hours of major cities, due to this many people stand at
roadside waiting for the taxis. To overcome the problemone
optimal solution is to increase the taxis. But it brings some
negative effects, e.g., causing additional traffic on the road
surface and more energy consumption, and decreasing taxi
driver’s income. To address this issue, we introduce a Taxi
sharing system that accepts passengers’ real-time ride
requests sent from smartphones and schedules proper taxis
to pick up them via taxi sharing with time, capacity, and
monetary constraints.

3. System Architecture
Fig. 1 shows the architecture diagram of Taxi-
ridesharing system.TheSystemconsistsoftwoparticipants-
Driver and Rider. Both of them access the ride sharing
system through the ride sharingapplicationinstalledintheir
mobile device. To participate in the ride sharing, both of
them have to register for the first time using their mobile
application. This registration and loginprocessisaffectedby
the registration service and theuseraccountdata isstoredin
the Accounts profile database. Apart from the login data, the
accounts profile database also comprises of other details
such as the user address, Phone no, number of seats and the
car type in case of a driver. The process begins withthe rider
registering his ride through the mobile application. The ride
registration data comprising of source, destination address
and start time of the ride is then passed on to the Google geo
coding service through the ride sharing servicemodule.This
module converts the physical address into Geo location
coordinates and stores them in the Google fusion tables.The
rider after login searches for the ride through his mobile
application. The ride request isprocessedbytheridesharing
service. The filtered search result is presented to the rider
along with the driver details and cost. After the rider selects
a driver, rider request is passed on to the driver’s mobile
application by the ride sharing service. After the driver’s
approval, driver send confirmation message on rider’s
mobile phone and riderareenabledtocommunicatethrough
the ride sharing application. Once the ride starts, ride
tracking service starts tracking the ride using the GPS data
from the user’s mobile device. This data is temporarily
stored in the accounts profile database to provideassistance
in case of an emergency. After the completion of the travel,
rider provides the rating and comment for the driverwhich
is processed by the riding service and stored along with
driver’s profile data in the accounts profile database. The
cost of the of rider is calculated based on the distance and
cost propose by driver.

4.Module
There are three main module in the paper and they are as
follows
Module1 (Mobile Client Module)
Smart Phone (android)which is interface to the user
(driver/rider).After completing user registration they mark
their source and destination in real time period. Using this
information client display his ridesharing option. Using this
information they can communicate with each other.
Module2(Web service)
Mobile client will transmit user data to web service. Web
service transmits data to store in database. When user
request
Ridesharing option web service queries data from the
database, filter the data who do not fit and send only
appropriate user to mobile client.
Purpose flie
Only riders are considering for rider and driver are
consider for driver.
Timing constraint
Only the user who have upload the data before one hour.
Route Filtering
The route of te user are compares and if there are
sufficient matching points on the route they are
considered.The above filter give the number of users who
can be pooled with the requesting user in the path he/she
has chosen

Fare Calculation
The fare calculation function F=Pd where D is the traveled
distance and p is some constant price for unittravel distance
Module3
Google table serves as database to our project.This is free
service which is provided by google to efficiently store
geopoints online.Rider provide rate and comment fordriver
which is also store in database.

5. Taxi Searching Algorithm
The taxi searching module quickly selects a small set of
candidate taxis with the help of the spatio-temporal index.
Single-Side Taxi Searching
Suppose there is a query Q and the current time is tcur : g7is
the grid cell in which Q:o is located. g7‘s temporally-ordered
grid cell list g7 Fig. 2. g7 is the first grid cell selected by the
algorithm. Any other arbitrary grid cell gi is selected by the
searching algorithm if and only if Eq. (1 holds, where ti7
represents the travel time from grid cell gi to grid cell g7. Eq.
(1) indicates that any taxi currently within grid cell gi can
enter g7 before the late bound of the pickup window using
the travel time between the two grid cells
ti7 þ tcur _ Q.pw. l (1)
find all grid cells that hold Eq. (1), the single-side searching
algorithm simply tests all grid cells in the order preserved
list g7 finds the first grid cell gf which fails to hold Eq. (1). In
Fig. 2, grid cell g3, g5 and g9 are selected by the searching
algorithm.
Fig3 Single side taxi searching algorithm
Dual Side Taxi searching Algorithm
The dual-side searching is a bi-directional searchingprocess
which selects grid cells and taxis from the originsideand the
destination side of a query simultaneously
Fig 4 Dual side searching algorithm
Consider the ride request illustrated in Fig. 3 where g7
and g2 are the grid cells in which Q:o and Q:d are located
respectively. Squares filled with stripes standforall possible
cells searched by the algorithm at Q:o side. These cells are
determined by scanning the temporally-ordergridcell listof
g7 which holds Eq. (2) is a candidate cell to be searched at
the origin side. Eq. (2) indicates that any taxi currently
within grid cell gi can enter g7 before the late bound of the
pickup window using the latest travel time between the two
grid cells.
tcur + ti7 <= Q.dw . l (2)
Squares filled with dots indicate the candidate grid cells
to be accessed by the searching algorithm at Q:d side select
all grid cells which holds Eq. (3), which indicates that any
taxi currently in gj can enter the g2 before the late bound of
the delivery window In this example, g6istheonlysatisfying
grid cell as shown by Fig. 3
tcur + tj2 <=Q. dw . l (3)

6. Conclusion
Real time taxi sharing system is very effectivemeansto
reduce pollution and the congestion of vehicles in cities. It
also provides an eco-friendly way to travel. It also provides
an opportunity to meet new people. System saves the total
travel distance of taxis when delivering passengers. Our
system can enhance the delivery capability of taxis in a city
so as to satisfy the commute of more people. The system can
also save the taxi fare for each individual rider while the
profit of taxi drivers does not decrease compared with the
case where no taxi sharing is conducted.
7. Future Work
In this proposed system the basic conceptof taxiridesharing
through real-time request generation and its acceptance In
future work may use social networking sites for real time
request.
