[0042] The invention works in following manner:

[0059]

[0043] Figure 2 illustrates a method of operation of the warning light system for enhancing road safety, in accordance with an embodiment of the present invention. This will be better understood by simultaneously referring to Figure 3A-3B that illustrate information flow diagram between the components of the system in an exemplary implementation, in accordance with an embodiment of the present invention.

[0060]

[0044] Figure 2 shows the method to obtain a warning light system 100, which detects and analyses the road conditions for safer driving. This phase initiates by receiving 202 real-time data related from the road using plurality of sensors and an infrared camera and process the same to determine road conditions. The real-time data may include a vast array of images and video feeds from the infrared (IR) camera 104 configured to receive sensory real-time data of the weather conditions and real-time images with high resolution of the road to determine the road conditions.

[0061]

[0045] According to an embodiment of the invention, the camera utilizes infrared rays and is of 5 megapixels thus forming high resolution images of the road conditions that help in accurate analysis and generation of alerts. These images provide the raw visual data necessary for the system 100 enabling the system to visually assess road conditions by detecting various weather conditions such as but not limited to fog, rain, snow, humid or high / low temperature conditions. In case of harsh weather or less or no visibility, the driver is alerted.

[0062]

[0046] Plurality of sensors are used to collect data of the road. The sensors include such as but not limited to, fog sensor, vibrational sensor, doppler sensor, limit switch sensor, ultrasonic sensor. The fog sensor collects data related to fog or other atmospheric conditions that affect visibility, while the vibration sensor provides data related to vibrations or shocks, providing additional information about the road environment. The speed of any vehicle or object is detected by the doppler sensor. This sensor helps the system 100 to detect moving objects like vehicles or pedestrians, and assess road conditions, especially in low-light or nighttime situations. The Doppler sensor is a crucial tool for detecting motion, including vehicles and pedestrians, enhancing traffic analysis and response systems' effectiveness. Its capability to discern movements aids in monitoring traffic flow dynamically, while also detecting reduced speeds on highways, crucial for identifying potential traffic jams or accidents. By leveraging Doppler sensors, these systems can promptly react to evolving situations, thereby improving overall traffic management and safety measures. Further, the limit switch sensor monitors the physical limits or positions of moving parts within the system, enhancing precision and safety in the system's mechanical components. It ensures that mechanical components operate within safe limits and provides feedback for system control and monitoring. Furthermore, the distance of objects around the warning light system 100 is detected by the ultrasonic sensors, aiding in assessing traffic situations and identifying potential obstacles or congestion. These sensors and IR camera collect the data of the above-mentioned various weather and road conditions and send it for processing to the processor 1024.

[0063]

[0047] Fig. 3A depicts the process flow of the real time environmental data collected by sensors 106, but not limited to, fog sensor, ultrasonic sensor, doppler sensor and transmitted to the processing module 102. The processor 1024 receives the data and processes it to determine various weather conditions such as level of fog to ensure safe visibility levels to the driver, temperature, humidity level, rain and snow. This information is crucial for issuing warnings specific to weather- related challenges.

[0064]

[0048] Next, in step 204, the GPS module determines the precise geographical location of the warning light system. This information is crucial for providing accurate and location-specific warnings to drivers, improving overall effectiveness. This data is used to detect the warning light position to track the machine and to use these coordinates on the map inside the platform. The GPS module 108 plays a crucial role in providing location-specific warnings and alerts to drivers. Further, the GPS data gathered by the GPS module 108 may be used to provide enhanced route guidance to the driver. For instance, the system can suggest alternative routes or provide real-time traffic updates to help drivers avoid congested areas or road closures. Furthermore, in the event of emergencies such as accidents or road closures, the GPS module 108 transmits location data to emergency response services or traffic management authorities nearby. This enables quick and targeted responses, such as dispatching emergency vehicles or redirecting traffic flow.

[0065]

[0049] The collected data undergoes a preprocessing step 206, where it is analysed to generate an appropriate warning signal or alert for the driver. Here, weather, vehicle proximity and road conditions are processed by appropriate wired communication or wireless communication through wireless antenna placed on the system 100. The processor 1024, on the receiving the input data from camera 104 and sensors 106, processes this visual input data along with sensor data to determine appropriate warning signals and alerts for drivers. In an embodiment of the present invention, the Zigbee antenna are powered by Zigbee technology. ZigBee antennas are antennas specifically designed to transmit and receive ZigBee wireless signals. They are connected to the ZigBee board 1026 and are responsible for establishing communication links between different units of the warning light system 100. ZigBee technology enables efficient and reliable data transmission between various components, enhancing the responsiveness of the warning light system. The ZigBee board 1026 coordinates the operation of the warning light system 100. It ensures that data from various sensors are received and processed efficiently, and that commands for activating LED warning lights 114 or displaying information are transmitted accurately.

[0066]

[0050] Then at step 210, the generated warning signal is now transmitted from central platform to the master unit then to the slaves unit to warning display for visual indication to the driver. The warning is transmitted to the warning information display by LED hazard lights. The LED hazard light includes a four-color warning light, utilizing LED flash technology. LEDs are semiconductor devices that emit light when an electric current passes through them. LED flash technology refers to the use of Light Emitting Diodes (LEDs) in a flash or strobe mode to produce intense bursts of light. LEDs can produce bright and intense light output, making them highly visible even in daylight or adverse weather conditions. This high intensity is used crucial in warning light system 100 to grab the attention of drivers and pedestrians effectively.

[0067]

[0051] Fig. 3B depicts the process flow of data captured via an infrared camera 104 or a videoimage camera that is capable of capturing high quality of fine images. This visual data of the road describes the road condition and is transmitted to the processor 1024 and processed, the processor 1024 sends an alert to the driver on detecting any unusual road conditions such as but not limited to, bump on the road, speedy vehicle approaching and proximity of the driver from the system 100. This alert is then transmitted by a wireless route through Zigbee board 1026 to the master unit, from the master unit to the platform, from the platform to the master by LTE, from master unit to the slave unit by ZigBee. The driver is alerted by a display of a suitable color of the warning LED light 114.

[0068]

[0052] This LED light features four colours: red, blue, yellow, and white, each serving distinct purposes.

[0069] 1) The red light blinks during emergencies, providing a clear alert signal.

[0070] 2) When the red and blue lights blink together, it signals an accident, congestion, or traffic jam ahead, alerting drivers to potential hazards and prompting caution. This combination provides a clear indication of road incidents, enhancing overall traffic safety and efficiency.

[0071] 3) The yellow light signifies weather conditions such as rain, dust, or fog, aiding in visibility during adverse weather. 4) Combining yellow and white lights indicates a detour, guiding drivers safely through alternate routes.
