DEVELOPMENT OF ROAD ACCIDENT ALERT AND POST-ACCIDENT ANALYSIS
SYSTEM
COMPLETE SPECIFICATION
DESCRIPTION
In order to improve rider safety by timely accident detection and thorough post-event
assessment, this project proposes a comprehensive road accident alarm system made especially for
motorcycles. A GSM module and a variety of sensors are combined in the system to provide a
strong, non-loT-based solution that guarantees dependable operation even in places with spotty
internet access. A tilt sensor for stab~ity detection, a temperature sensor to keep an eye out for any
post-accident overheating hazards, a\gyroscope and accelerometer to gauge the orientation and
intensity of impacts, and a vibration sensor to identify possible impact events are the main parts of
this system. When used in tandem, these sensors record and evaluate vital information both during
and after an accident, enabling a precise evaluation of the event and the stale of the bike. When an
accident is detected, the GPS module locates the scene, and a GSM module sends an SMS alert to
pre-configured emergency contacts with the coordinates and accident information. Since the GSM
module uses cellular networks to function, this method guarantees quick emergency response
without the need for an internet connection. The system evaluates the bike's condition and notifies
emergency contacts of possible dangers to provide an additional layer of post-accident usefulness.
For instance, the temperature sensor detects overheating that may pose a fire hazard, and the
banery health monitor assesses the power system's condition after an impact. These evaluations
offer vital infonnation on the bike's condition, enabling riders or first responders to handle or
transport the vehicle safely. This system, which is firmly mounted beneath the bike seat, is made
to resist collisions and stay shielded from direct impact, maintaining sensor operation. With no
external cloud or Internet of Things dependencies, the entire system is self-contained and relics on
onboard data collecting and processing. Logging incidents is made possible by optional data
storage and might be a useful record for insurance or repair evaluations.
FIELD OF INVENTION
This invention pertains to vehicle safety systems, more especially to a motorcycle accident
detection and alert system that integrates post-event analysis with real-time accident alarms. The
system uses a variety of sensors, including as accelerometers, gyroscopes, vibration, tilt, and
temperature sensors, to identify and evaluate traffic accidents involving two-wheeled vehicles. Its
purpose is to improve rider safety and reaction efficiency. This invention is a non-loT, standalone
gadget that functions without internet access, depending instead on a GSM module for emergency
communication, in contrast to conventional loT-based warning systems.
The assessment of vehicle conditions after an accident, including orientation, battery health, and
possible overheating hazards, is another area in which the innovation is applicable. In addition to
supplying useful insights into the accident severity and bike state, the idea aims to improve reaction
time and safety measures in the wake of a motorcycle accident by giving emergency contacts instantaneous and actionable data. Thus, improvements in safety alert systems, onboard postaccident
diagnostics, and vehicle accident detection that arc especially suited to two-wheeled
vehicles fall under the purview of this innovation.
BACKGROUND OF INVENTION
Due to riders' fragility and the fact that two-wheeled vehicles have fewer safety features than fourwheeled
vehicles, motorcycle accidents are a serious global safety concern. Getting help quickly
after an accident is essential for improving survival rates and lessening the severity of injuries.
Conventional accident alarm systems frequently depend on internet-based and loT technology,
which could not perform well in isolated locations with poor network connectivity. Moreover, a
lot of current systems don't tell rescuers about the state of the car after an accident, so they aren't
aware of any risks like overheating or battery damage.
By providing a dependable, non-loT-based accident alert system made especially for.
motorcyclists, this technology fills these gaps. It uses a variety of sensors that don't require an
internet connection to combine accident detection and post-accident analysis. The system uses a
GSM module, which works on cellular networks and guarantees that the warning can be issued
even in distant areas, to instantly notify pre-designated emergency contacts in the event of an
accident.
The innovation evaluates the motorcycle's condition following the collision, including tilt,
temperature, and battery health, in addition to location and impact data. By identifying possible
hazards, this post-accident study provides an additional degree of safety and enables responders or
riders to manage the situation more skillfully. This invention greatly improves motorcycle accident
response and rider safety by combining alerting and diagnostic capabilities into a single system,
offering a workable solution for both urban and rural locations without depending on loT
infrastructure.
