I. Information
There are many dangerous roads in the world like
mountain roads, narrow curve roads, T roads. In these
some mountain roads will be very narrow and they contain
so many curves. For example Kinnaur road in Himachal
Pradesh, Zoji La Pass in the Himalayas, the Road of Death
Bolivia, Fairy Meadows Road (Pakistan) [1]. If the road is
in remote areas sometimes there will be the chances of
animals on the road and that is also dangerous if the driver
couldn’t see them. For example Pitt Enterprises Ltd. v.
Farkes, 2005 BCCA 511 the defendant collided with a
moose standing in his lane and that caused his vehicle to
move into the oncoming lane and strike the plaintiff’s
vehicle [2].
In some of the curve roads, the other end of the curve road
cannot be seen by the driver because of the obstacles like
trees or rocks etc present in the middle. In these type of
roads thousands of people die because careless or presence
of unexpected obstacles. According to Million Death
Study (MDS) about 2.3 million people die in India per
year. In that 137 thousand is because of road accidents.
That is about 377 people per day. In that 3.7% because of
failed to look the road [3]. The problem in these curve
roads is drivers can’t able to see the vehicle or obstacles
coming from other end of the curve. If the vehicle is in
very speed then it is difficult to control and there are
chances of falling to cliff. The solution for this problem is
alerting the driver about the obstacle or vehicle. Usually
horn is used for this purpose. But in the rainy seasons horn
will not be heard. Some people will not use horn itself. So
horn is not a good solution to solve this problem. These
are the major reasons for accidents [4]. To avoid these
problems in curve roads or T roads we are introducing
sensor based accident prevention system. That is we are
keeping ultrasonic sensor in one side of the road before the
curve and keeping a LED light after the curve [5].
Ultrasonic sensor which is also called as obstacle sensors
sends signal as pulse from trigger. If vehicle is present
signal will hit the vehicle and it is received by the sensor
II.ADVANTAGES
1. Avoid accidents in curve roads mountains roads and
hill roads.
2. Saves thousands of lives.
3. Easily implementable to the existing roads.
4 .Fully automated (No person is required to operate).
5. Installation cost is very less.
6. Vehicle monitoring systems can be implemented easily.
lll. FUTURE WORK
1. Arrangements to protect the sensor from being damaged
in critical places.
2. Decrease the size of unit so that it occupies small place
and easily kept in narrow roads.
3. Implementing the system to detect number of vehicles
and velocity of vehicle.
