Abstract-In India, there is a road accident
happening in every 2 seconds and a person
is dying in a minute because of road
accidents. Out of all such accidents, 95% Of
it is out of driver’s carelessness Good
driving is all about Maintaining a speed
limit of 50kmph in cities, Applying breaks
without jerks, avoiding sharp turnings,
positioning of the vehicle on the road when
cornering as well as being in the correct gear
and at the right speed.Dear app is an offline
app that keeps a track of all these factors of
a driver and records a driver’s efficiency. It
then sends an impulse signal to the main
server where the database of each driver will
be recorded. It then marks the driver’s
efficiency. All you need is just a smart
phone and a dear app.
1. INTRODUCTION
Conventional speed governors are designed
only to limit the maximum speed attainable
by a vehicle. We are trying to implement
Preventive Safety Systems using advanced
Mechatronics and Active Safety Methods.
This system can provide necessary warning
and aid to the driver when required.
Nowadays speed governor is a common
term of which almost everyone is familiar
with. Speed governor is just a device that
alerts the driver and decrease the speed of
the vehicle when the vehicle speed exceeds
the reference value entered in the speed
governor. This thought i.e. whether this
speed governor which merely controls the
speed of a vehicle is worth in a fast moving
society of ours ended up in an alternative for
speed governor that can take decisions
according to varying environmental and
driver behavior.
Over view
Active safety systems are gradually
becoming practical with advance in
environment sensing and vehicle control
technologies. On the other hand analyses of
driver mistakes retrieved to as human errors,
in road accidents has shown that driver
continues to make mistakes in the cognition
of their external world and judging the safe
or not safe. A total 60% of all rear and
almost 30% of head-on collision could have
been avoided if the driver reacted mere a
half a second early. So in this paper we are
focusing on driver aids which combines both
environment senses and driver monitoring
system.
decisions according to varying
environmental and driver behavior. We are
sure that the dear app that we have proposed
would bring in dramatic changes in the field
of driving as well as in the current Indian
traffic system if implemented
2. TRACKING SYSTEM:
Object Tracking and Classification
Using the data from environmental sensing
systems, the drivers are classified according
to their skills. The main classifications of
vehicles can be like cars, trucks/buses,
motorcycles//bicycles and pedestrians.
Additional data like reflexivity can be used
to detect signal posts and such objects. The
pedestrians are identified by comparing the
acquired data with some out lines stored in
the history. It is almost like video image
processing. If the obstacle is identified as a
pedestrian some complicated algorithms are
used to track the movements of the
pedestrian. The development of driver
supporting system that address the mistakes
made by drivers requires Environmental
sensors, driver monitoring system and a
brake assist system to ordinate vehicle
control.
Environmental Sensors
The environmental sensor system consists of
equipments that make the vehicle aware of
its surroundings. In general it consists of
radars, infrared night vision systems, high
resolution digital video for medium distance
observation, and ultra sonic systems for ultra
short monitoring. In our system we are u
