SMART SECURE AND WARNING SYSTEM IN HAIR PIN BENDS AT HILL
STATIONS
 ABSTRACT
 India has the world's highest rate of traffic accidents. The majority of road accidents occur when
drivers are traveling at high speeds or when they are unaware of other vehicles approaching from
the opposite direction, particularly in deep curves (hairpin curves). Vehicles traveling around
hairpin bends are extremely susceptible to accidents due to a lack of communication and
visibility over the curves. Consequently, vehicles must drive with extreme caution when
traversing hairpin curves. The type of vehicle is not detected by the current systems, which only
detect incoming vehicles. Consequently, there is traffic congestion and travel delays. The
proposed system is used to assist the vehicle coming from the opposite side of the hairpin after it
has detected vehicles on one side of the curve. The proposed system aims to classify various
vehicles traveling in one direction of the hairpin road and notify vehicles traveling in the
opposite direction via a display board. The information regarding the vehicle category, the
amount of time required to pass the vehicle at the curve, and the number of vehicles in the curve
are displayed on this LED display board. In any circumstance, we can reduce accidents on deep
curve roads in this manner.
EXISTING SYSTEM
       India’s automobile fleets grow at an annual rate of around 7 to 8%. Road accidents
contribute for over 1.2 Million mortalities worldwide demand for the safe vehicular country is
very high.
         The privation of medical facilities during emergency and the increased number of
accidents is a major concern to consider in the modern day world.
       The accident in the hilly region occurs mainly due to the design of curved roads and
hairpin bends, the lack of tracking or monitoring facility makes the accident situation worse in
terrain regions.

Disadvantages
              High accidents occur in Hills Region
              lack of advanced infrastructure in hills regions
Proposed System:
       An ultrasonic sensor is used in an accidentprevention system. Ultrasonic sensors, an I2C,
and an Arduino were all used to avoid the accident. Along with ultrasonic sensors, buzzers,
LEDs, and LCD displays are installed on both sides of the road.
       Ultrasonic sensors identify the direction from which the cars are approaching to warn
drivers and prevent crashes. The controller then sends signals to buzzers, LEDs, and LCD
screens, which display "car is Ahead."
       In this system, a distance of the vehicle is sensed and give three stages of alerts to the
opposite side driver, these alerts are based on the distance from the vehicle to the sensor position.
Using this system, the drivers can easily judge the arrival of vehicles from the other side more
confidently
Advantages:
              High vehicle prediction accuracy to avoid accidents
              The drivers can easily judge the arrival of vehicles
