3. Introductory Problem Statement
SmartDriver is a mobile application which has been designed to keep track of the
driver's driving habits and to generate a real time report using the driver's driving
statistics and locations. This report can then be submitted to the registered users (parents
or managers of the transportation companies renting their vehicles) who want to analyze
the statistics of the driving behavior. This software basically helps in generating a
detailed tracking report of the user and also allows for online tracking of the user's
location. The detailed report can then be sent to the registered users as and when
scheduled.
Features of the application:
➢ It calculates rapid acceleration and hard breaking from the GPS data from the
smart phones.
➢ It reports the GPS locations of the person driving to the parent, whenever rapid
acceleration and hard breaks occurs.
➢ It provides the feedback to the driver periodically on the top speed reached,
number of rapid accelerations and hard breaks.

4. History and Research
SmartDriver is a mobile application which helps in keeping track of car speed
when teenagers are driving by using vehicle tracking devices.
Several types of vehicle tracking devices exist. Typically they are classified as
passive and active. Passive devices store GPS location, speed, heading and
sometimes a trigger event such as key on/off, door open/closed. Once the vehicle returns
to a predetermined point, the device is removed and the data downloaded to a computer
for evaluation. Passive systems include auto download type that transfer data via wireless
download. Active devices also collect the same information but usually transmit the
data in near-real-time via cellular or satellite networks to a computer or data center for
evaluation.
Actually, there are many car speed detectors to detect the speed of car. Such as
The Radar Detector, Laser detector, GPS speed tracker and so on.
Radar detector and laser detector are using the same principle. They use Doppler
radar to beam a radio wave at the vehicle, and then infer the vehicle's speed by measuring
the Doppler effect-moderated change in the reflected wave's frequency. These are most
common device to detect a car speed. But they are most used by police or law
enforcement. Most radar detectors are used so the driver can reduce the car's speed before
being ticketed for speeding. This is one way to find people if drives safely in some cases.
But there is a real limit for Radar detectors if we want to insure driver are driving safely
in the whole trip. Firstly, it’s really not efficient to set up Radar detectors in every mile
beside the road, it would cost a lot of budget to do that. Secondly, it is not a real-time
system. It can’t enforce driver reduce their dangerous driving behaviors immediately.
The Global Positioning System (GPS) is a space-based satellite navigation system
that provides location and time information in all weather conditions, anywhere on or
near the Earth where there is an unobstructed line of sight to four or more GPS satellites.
Nowadays, hundreds of the GPS devices are used in cars. They are very functional. Most
of GPS devices can notify locations, speed of car, speed limits of the road, and the
predicting arrival time of destinations and so on. Basic GPS measurements yield only a
position, and neither speed nor direction. However, most GPS units can automatically
derive velocity and direction of movement from two or more position measurements. The
disadvantage of this principle is that changes in speed or direction can only be computed
with a delay, and that derived direction becomes inaccurate when the distance travelled
between two position measurements drops below or near the random error of position
measurement. GPS units can use measurements of the Doppler shift of the signals
received to compute velocity accurately.
GPS is widely used in cars, but there’s rarely to see people use GPS to monitor a
teenager’s driving behaviors. SmartDriver has more advantage for parents to keep
tracking their children’s driving behaviors by smartphones than just a GPS device.

5. Objectives and Goals
Objectives:
The main objective of SmartDriver is to prevent accidents and improve the driving habits
of people by providing feedback about their drives and generating a report on their drive.
With this application being used by law enforcement we hope to see a rapid decline in
crimes such as hit and runs, drive by shootings and robberies. We are very optimistic that
SmartDriver will make the roads much safer for people to drive on.
Goals:
Reduce the amount of accidents
Reduce amount of traffic jams caused due to accidents
Give parents a peace of mind about the safety of their child driving
Quality of life:
Everyday in the USA (even worldwide) people are losing their lives as a result of
careless driving. It’s so unfortunate to see a person lose his or her life over something that
can easily be prevented. Imagine a world where accidents are a rare occurrence. We have
high hope that SmartDriver will be able to make this a reality in the near future.

notifications to users registered as parents for that user.
Driver Score calculations
Following are the rules to consider for calculating the score.
a. Driving alerts score is all penalty points collected prior week.
b. Rapid Acceleration: (Delta distance/Delta time measured in meter/sec).
Calculate speed over 10 sec period’s vs. prior 10 sec period or collect
estimated speed info from GPS. Rule: If acceleration is +1m/sec sq2, then
it’s one penalty point.
c. Hard braking: Measure distance over 5 sec period’s vs. prior 5 sec period
measured in meter/sec. If delta is -1.5m/sec sq2, then it’s one penalty.
6

8. d. Speeding: If driving speed is default +70 mph (adjustable in account
setup) for more than 20 sec. one penalty point.
e. Define start of trip. Perhaps refine home start location based on location
most frequently used.
f. Define end of trip.
g. Calculate exit direction: After car speed goes to zero for 5 sec, measure
motion (right/left) based on data from gyroscope 6 axis motion. If motion
more than 1 meter sideway then define status as exit left (status a - driver)
or right (status b - passenger) based on geo location of app.

9. User Profile
The SmartDriver app is built with a focus on safe driving, importantly minimization of
road accidents by delivering constant feedback on driving exercises. While the auxiliary
benefits can include review of fuel consumption, professional driving evaluations and on
road assistance with generic car problems. The app can prove to come in handy in
establishing safe driving skills.
The commonplace use of SmartDriver would thus be catering the novice drivers
with useful statistics to work on in order to develop a sense of driving maturity. Young
inexperienced drivers are likely to benefit from SmartDriver with someone monitoring
their driving habits and providing exclusive assessment. In effect, the app can help
anyone who needs to find out how their driving pattern is different and areas in which
they can improve.
As talked of earlier, transport companies can utilize SmartDriver to evaluate
driving performances of their employees and direct them with specific instructions. Also,
anybody who is driving a car can make the use of this app from trip ratings, knowing cost
efficiency of their driving and how their casual motoring is affecting their vehicle.
Further assistance can be provided in finding the gas stations, nearby repair shops and
traffic updates.
