Additionally, the system facilitates damage detection of road, adaptive material application, and sustainable water management to enhance pavement durability, traffic safety, and long-term infrastructure performance.

BACKGROUND OF THE INVENTION

[0002] Road surfaces are continuously exposed to traffic load, temperature changes, rainfall, and environmental pollutants, which gradually lead to cracks, potholes, surface deformation, and material degradation. Increasing vehicle density and extreme weather conditions further accelerate pavement wear and reduce road life. Damaged roads create safety risks for motorists, increase vehicle maintenance costs, and disrupt smooth transportation. Timely detection and repair of minor surface defects are essential to prevent further deterioration and costly large-scale rehabilitation. In addition, poor drainage and water accumulation on road surfaces weaken structural layers and contribute to faster breakdown.

[0003] The traditional methods of road surface maintenance involve manual inspection of pavements by workers and repair using basic tools and heavy machinery, which are labor-intensive, time-consuming, and dependent on scheduled surveys rather than real-time assessment. The existing methods, such as sensor-based monitoring vehicles and patching machines, have improved detection and repair efficiency by introducing mechanization and digital analysis, but they often involve high installation and operational costs and require trained personnel for operation and maintenance.

[0004] CN106709604A discloses a road surface maintenance early warning method and device; the method of one specific embodiment comprises the following steps: obtaining maintenance data of each sub road section of an object road, wherein the maintenance data comprises the start time of each maintenance work of said sub road sections; obtaining vehicle traffic data passing each sub road section from the start time of the previous maintenance work, wherein the vehicle traffic data comprises vehicle traffic flow, and load capacity and excess weight of each vehicle; determining the traffic flow integral amount of said sub road section according to the vehicle traffic flow of each sub road section and the load capacity and excess weight of each vehicle passing the sub road section; forming early warning information of the road surface maintenance work of each sub road section in the object road according to the traffic flow integral amount of each sub road section of the object road. The method and device can realize dynamic early warning of the road surface maintenance work.

[0005] CN2856127Y discloses a roadside rainwater-collecting system is a novel safe high-efficiency environment-friendly water drainage system used for urban water drainage, can solve hazard of accumulated water on urban roads due to rainstorm in recent years, and improve water drainage effect of road. The utility model combines 'roadside concrete rainwater-collecting stone' and 'high-permeability concrete rainwater-collecting brick' provided with water drainage holes into horizontal T-shaped full-enclosed high-permeability urban roadside rainwater-collecting system, and replaces conventional open-type road gutter with drainage system composed of water-permeable concrete having impurity-filtering function. The utility model can be widely used for water drainage systems of urban road, square, highway, airport, etc. The system has advantages of full enclosure, no blockage, maintenance free, high rainwater-collecting effect, and low water drainage failure rate. All pre-fabricated members can be industrially produced and conveniently constructed. Rainwater-collecting well is saved to avoid road danger and increase effective width of road. Series of products with different drainage powers are available to satisfy different rainfall intensities of different areas.

[0006] Conventionally, many systems are disclosed in the prior art that provide a way for monitoring and repairing road surfaces in urban and highway environments. However, these existing systems often lack coordinated monitoring, precise damage detection, and integrated repair and water management capabilities required for effective infrastructure maintenance, resulting in delayed intervention, uneven repair quality, increased operational costs, and reduced pavement lifespan.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a system that requires to be capable of accurately monitoring road surface conditions, identifying damaged or degraded portions, and performing precise maintenance in a coordinated manner. In addition, the developed system also needs to enable controlled material application, support effective surface water management, adapt to varying environmental and traffic conditions, and enhance overall pavement durability while reducing operational delays and maintenance costs.

[0020] As used herein, the singular forms “a,” “an,” and “the” designate both the singular and the plural, unless expressly stated to designate the singular only.

[0021] The present invention relates to an automated system for road restoration utilizing rainwater that is designed to observe, maintain, and restore road pavements on a continuous basis to ensure improved surface condition and operational safety. Additionally, the system also manages surface water and adapts to changing environmental and traffic conditions to support sustainable road maintenance and long-term infrastructure performance.

[0022] Referring to Figure 1, an isometric view of an automated system for road restoration utilizing rainwater is illustrated, comprising a vertical hollow column 101, a sensor array comprising a thermal camera 102 is arranged with the column 101, a mobile body 103 housed within a lower compartment 104 defined within the hollow column 101 having a curved sliding gate 118 , the mobile body 103 is equipped with a LiDAR (Light Detection and Ranging) module 106 and a hyperspectral scanner 107, the mobile body 103 comprises multiple omnidirectional wheels 108, a storage chamber 109 comprising an integrated heating element 110 installed in the mobile body 103, a sprayer array 111 positioned on the lower section of the mobile body 103, a rainwater management assembly arranged adjacent to the vertical column 101 comprising a cascading plate 105 equipped with a chute 112, a container 113 associated with the system, the cascading plate 105 comprises one or more micro piezoelectric actuators , a plurality of sprinklers 114 arranged on lateral sides of the road surface, the sprinklers 114 are directionally adjustable via an integrated swivel joint 115, an LED (Light Emitting Diode) array 116 integrated around the mobile body 103, and a holographic projection unit 117 mounted on the column 101.

[0023] The system disclosed herein comprises a vertical hollow column 101 which serves as a primary structural support. The vertical hollow column 101 is preferably constructed from durable materials including but not limited to steel, reinforced concrete, or composite materials, providing stability to the system and withstanding environmental exposure, traffic-related vibrations, and external mechanical stresses encountered in road environments.

[0024] A sensor array is arranged with the column 101 to monitor environmental conditions, traffic density and scan a road surface to enable a linked control unit to detect heated, damaged or degraded portions requiring maintenance. The sensor array comprises an IoT (Internet-Of-things) module, a radar module, and a thermal camera 102. The IoT module is configured to continuously fetch real-time environmental data including temperature, humidity and rainfall intensity. The IoT module comprises a temperature sensing module, a humidity sensor and a rainfall sensor. The temperature sensing module is configured to monitor the ambient temperature of the road surface and surrounding environment. The temperature sensing module continuously measures the thermal conditions of both the road surface and the surrounding air to support preventive maintenance decisions. The temperature sensing module utilizes a thermocouple that detects temperature variations. The thermocouple operates based on the Seebeck effect, where two dissimilar metal wires joined at a measuring junction generate a small voltage proportional to temperature differences.

[0025] The sensing junction is embedded near or within the road surface to accurately monitor ambient and surface temperature, while the reference junction is maintained at a known temperature inside the sensor module. When temperature changes occur, a millivolt signal is produced and transmitted to a signal conditioning circuit. The signal conditioning circuit amplifies the low-level voltage, performs cold-junction compensation, filters noise, and converts the analog signal into digital data through an analog-to-digital converter. The processed temperature data is then sent to the control unit for analysis, enabling timely detection of freezing conditions and preventive maintenance actions.

[0026] The humidity sensor is configured to monitor the moisture levels in the environment and on the road surface. The humidity sensor measures moisture levels in the surrounding air and near the road surface to assess wetness and potential icing conditions. The humidity sensor uses a capacitive sensing element consisting of two conductive electrodes separated by a hygroscopic dielectric material. When environmental humidity changes, the dielectric material absorbs or releases water vapor, altering its dielectric constant and causing a measurable change in capacitance.

[0027] The capacitance variation is converted into a corresponding electrical signal through an integrated signal conditioning circuit. The signal is amplified, filtered to remove environmental noise, and converted into digital data using an analog-to-digital converter. The control unit then calibrates and processes the humidity readings alongside temperature data to evaluate moisture trends.

[0028] The rainfall sensor is configured to monitor the intensity and occurrence of rainfall. The rainfall sensor detects the occurrence and intensity of precipitation to support real-time maintenance decisions. The rainfall sensor operates using a tipping-bucket arrangement to measure precipitation intensity and occurrence. Rainwater is collected through a calibrated funnel and directed into one of two small buckets mounted on a pivot. Each bucket is designed to tip when the bucket accumulates a specific volume of water, corresponding to a fixed rainfall amount. When tipping occurs, a magnetic reed switch generates an electrical pulse.

[0029] The control unit counts these pulses over time to calculate rainfall intensity and total precipitation. The signal is filtered to remove false triggers caused by vibration or debris. The processed rainfall data enables the control unit to activate drainage arrangement, adjust road surface treatments, or initiate safety alerts during heavy rainfall conditions.

[0030] In a tipping-bucket design, rainwater is collected through a funnel into a small dual-chamber bucket. When a predefined volume of water fills one chamber, the water tips, generating an electrical pulse counted by the control unit. The frequency of the pulses corresponds to rainfall intensity. In optical sensors, infrared light is transmitted across a sensing surface, and raindrops disrupt the light path, altering the received signal. The generated signals are conditioned, filtered, and converted into digital data. The control unit processes rainfall intensity readings to trigger drainage systems, adjust surface treatments, or issue alerts during heavy precipitation events.

[0031] The IoT module functions as a data acquisition and communication unit. The IoT module integrates environmental sensors such as temperature sensor, humidity sensors, and rainfall sensor that continuously collect real-time atmospheric data. The control unit processes the raw sensor signals, performs calibration, filtering, and noise reduction, and converts them into usable digital values. The processed data is analyzed locally using embedded protocol to detect adverse conditions like icing risk, surface wetness, or heavy precipitation. The protocol used here is a Random Forest classifier. The IoT module then transmits the information via wireless communication protocols to the control unit. Based on predefined thresholds and predictive models, maintenance actions such as de-icing, drainage activation, or surface treatment are triggered efficiently and proactively.

[0032] The radar module is configured to monitor traffic density, vehicle speed, and movement patterns. The radar module operates using microwave-wave signals to monitor traffic density, vehicle speed, and movement patterns. The radar module transmits high-frequency electromagnetic waves toward the roadway through a transmitting antenna. When the waves strike moving vehicles, they are reflected back to the receiving antenna. Using the Doppler effect, the radar module measures frequency shifts between transmitted and received signals to calculate vehicle speed. The time delay and signal strength help determine distance and vehicle presence. The received signals are processed through mixers, amplifiers, and analog-to-digital converters before being analyzed by the control unit. The processed traffic data is used to assess congestion levels and adjust maintenance operations safely without disrupting vehicle flow.

[0033] The thermal camera 102 is configured for flexible directional scanning. The thermal camera 102 operates by detecting infrared radiation naturally emitted from the road surface and surrounding objects. The thermal camera 102 uses an uncooled microbolometer sensor array that absorbs infrared energy and converts temperature variations into electrical resistance changes. The variations are processed into digital thermal images representing surface temperature distribution. The thermal camera 102 is mounted on a motorized pan-tilt arrangement, enabling flexible directional scanning across different road sections.

[0034] The motorized pan-tilt arrangement is a mounting arrangement that allows the thermal camera 102 to rotate horizontally (pan) and vertically (tilt) using electric motors. The motorized pan-tilt arrangement enables controlled directional movement so the camera can scan different areas without being physically repositioned. Internal signal processing circuits perform noise reduction, temperature calibration, and image enhancement to ensure accurate thermal mapping. The processed thermal data is analyzed by the control unit to detect cold spots, heat loss areas, or early ice formation.

[0035] A mobile body 103 is housed within a lower compartment 104 defined within the hollow column 101. The mobile body 103 is having a curved sliding gate 118 on an outer periphery of the street light pole to be selectively deployed to open and enable the mobile body 103 to precisely navigate, monitor material composition and surface integrity of the road surface. The curved sliding gate 118 operates through a motorized slider assembly to enable controlled deployment of the mobile body 103. The curved sliding gate 118 is shaped to conform to the curvature of the hollow column 101 and is mounted on precision-engineered curved guide rails. A stepper motor drives a lead screw connected to the panel of the gate. When activated by the control unit, rotational motion from the motor is converted into linear motion, smoothly sliding the gate along the curved track. The control unit provides real-time feedback to ensure accurate opening and closing.

[0036] The mobile body 103 is equipped with a LiDAR (Light Detection and Ranging) module 106 and a hyperspectral scanner 107. The LiDAR module 106 is configured to map damaged or degraded portions. The LiDAR module 106 operates by emitting rapid pulses of laser light toward the road surface to generate high-resolution 3D maps. A laser diode transmits short-duration pulses, which reflect off the roadway and return to a photodetector. The LiDAR module 106 measures the time-of-flight between transmission and reception to calculate precise distances. By scanning across the surface using a solid-state beam steering arrangement, the LiDAR module 106 creates a dense point cloud representing road geometry. Internal signal processing filters noise, compensates for ambient light interference, and converts analog return signals into digital spatial data. The control unit analyzes elevation variations, cracks, potholes, and surface deformations. The mapped data enables accurate identification of damaged or degraded areas, allowing targeted and efficient maintenance operations.

[0037] The hyperspectral scanner 107 is configured analyze road material composition during movement and dispensing operations. The hyperspectral scanner 107 operates by capturing reflected light from the road surface across hundreds of narrow, contiguous spectral bands. The hyperspectral scanner 107 uses a broadband illumination source, and reflected light is directed through an optical lens into a diffraction grating, thereby separating the light into distinct wavelengths, which are detected by a 2D sensor array. Each pixel records a full spectral signature, forming a hyperspectral data cube containing both spatial and spectral information. The control unit performs radiometric calibration, noise reduction, and spectral normalization to ensure accurate material identification. Embedded protocols compare spectral signatures with a reference library to determine road material composition, contamination levels, or degradation. The protocol used is a Support Vector Machine.

[0038] The mobile body 103 comprises multiple omnidirectional wheels 108 for precise motion and navigates to identified target regions using positional mapping via the LiDAR module 106. The omnidirectional wheels 108 enable precise and flexible movement of the mobile body 103 across the road surface. Each omnidirectional wheel 108 consists of a central hub fitted with multiple passive rollers mounted around its circumference at specific angles, 45 or 90 degrees. The rollers allow the omnidirectional wheel 108 to move not only forward and backward but also laterally and diagonally without changing orientation. Each omnidirectional wheel 108 is independently driven by a dedicated motor, often coupled with an encoder to provide real-time rotational feedback. The control unit processes positional data from the LiDAR module 106 and computes individual wheel 108 velocities. By coordinating wheel 108 speeds and directions, the control unit achieves smooth, accurate navigation to identified target regions, ensuring stable positioning during monitoring and maintenance operations.

[0039] A storage chamber 109 is installed in the mobile body 103 for storing a mixture that is thermally maintained at a pre-defined temperature via an integrated heating element 110 linked with a temperature sensor. The temperature sensor works in the same manner as the temperature sensing module works as mentioned above to monitor that the mixture is thermally maintained at a pre-defined temperature.

[0040] The integrated heating element 110 comprises an electrically resistive heating coil uniformly embedded along the chamber 109 walls to ensure even heat distribution throughout the stored mixture. When electrical power is supplied, the resistive element converts electrical energy into thermal energy through Joule heating. The heating element 110 is electrically connected to a power control module, which regulates current flow based on control signals received from the onboard control unit. The control unit processes temperature data from the linked temperature sensor and modulates the heating output in a closed-loop feedback arrangement to maintain the predefined temperature setpoint. Thermal insulation surrounding the storage chamber 109 minimizes heat loss, improves energy efficiency, and ensures stable, consistent heating.

[0041] A sprayer array 111 is positioned on the lower section of the mobile body 103 to apply a uniform layer of mixture over damaged portions. The sprayer array 111 is also configured to dynamically adjust thickness and gradient of the dispensed mixture to form channel gaps for surface water drainage. The sprayer array 111 consists of a pressurized mixing chamber, precision pump assembly, flow control manifold, and multiple electronically actuated spray nozzles arranged in a linear grid beneath the mobile chassis. The mixture comprising binder, aggregate slurry, or polymer-modified compound is continuously agitated inside the chamber to prevent settling. Variable-speed pumps regulate material flow based on real-time input from hyperspectral scanner 107 and thermal camera 102. Each nozzle is independently controlled through the control unit driven valve assembly, enabling differential flow rates to adjust thickness and create programmed gradients for water drainage channels.

[0042] A rainwater management assembly is arranged adjacent to the vertical column 101. The rainwater management assembly includes a cascading plate 105 equipped with a chute 112. The cascading plate 105 is being adapted to extend outward upon rainfall detection via the sensor array to align with the channel gaps. Further, the cascading plate 105 direct rainwater toward a container 113 associated with the system through a filtration unit. The cascading plate 105 functions as an active rainwater diversion arrangement. Upon rainfall detection by the sensor array, the control unit triggers the cascading plate 105 to extend outward.

[0043] The movement aligns the cascading plate 105 precisely with the channel gaps in the road surface. When the cascading plate 105 extends to align with the channel gaps, the chute 112 directs the water flow efficiently from the surface into the container 113. Made of durable, water-resistant material, the chute 112 ensures minimal water loss and prevents debris from entering the collection pathway The water passes through the filtration unit before reaching the container 113, ensuring debris removal and water quality management. The filtration unit functions to purify rainwater collected from the surface before storage or reuse. The filtration unit contains multiple filtering layers such as coarse mesh screens, sediment filters, and activated carbon filters. The layers work sequentially to remove large debris, dirt, leaves, and suspended particles, ensuring only clean water passes through. The cascading plate 105 efficiently channels rainwater away from the road surface, preventing accumulation and potential damage, while also enabling water collection for reuse, thereby enhancing road maintenance and durability.

[0044] The cascading plate 105 comprises one or more micro piezoelectric actuators for generating controlled vibrational patterns to maintain continuous water flow. The machine learning protocol dynamically adjusts vibration frequency and intensity based on real-time flow conditions. The micro piezoelectric actuators operate by converting electrical energy into precise mechanical vibrations through the inverse piezoelectric effect. Each micro piezoelectric actuator contains a piezoelectric ceramic layer i.e. lead zirconate titanate (PZT), sandwiched between conductive electrodes. When the control unit supplies a regulated voltage, the ceramic layer undergoes rapid dimensional changes expanding and contracting at controlled frequencies. The micro-deformations generate localized vibrational waves across the cascading plate 105 surface. By modulating voltage amplitude and frequency, the micro piezoelectric actuators produces adapted vibrational patterns that prevent water stagnation, reduce debris adhesion, and sustain uniform water flow.

[0045] The machine learning protocol employs real-time data analysis to optimize vibration parameters. The machine learning protocol continuously monitors flow conditions such as traffic density, surface texture, and environmental factors through sensor inputs. Using the data, the machine learning protocol leverages predictive models trained on historical and live data to determine the optimal vibration frequency and intensity needed for effective maintenance. The machine learning protocol adapts dynamically, adjusting vibration settings to match changing conditions, ensuring efficient surface repair while minimizing energy consumption and wear. Advanced protocols refine their parameters over time, improving accuracy and responsiveness. The protocol used is a reinforcement learning.

[0046] The reinforcement learning protocol continuously adjusts vibration frequency and intensity based on real-time sensor feedback and observed maintenance outcomes. The reinforcement learning protocol learns optimal control strategies by receiving performance-based rewards (e.g., repair effectiveness, energy efficiency, reduced wear) and refining its actions over time. Through ongoing interaction with changing environmental and traffic conditions, the reinforcement learning protocol improves its decision-making to maximize long-term operational efficiency.

[0047] A plurality of sprinklers 114 is arranged on lateral sides of the road surface and is fluidly coupled with the container 113. The plurality of sprinklers 114 is adapted for targeted distribution of filtered water towards road surfaces or roadside vegetation. The control unit coordinates rainwater collection, filtration, and redistribution in a closed-loop adaptive manner to maintain pavement integrity and sustainability. The plurality of sprinklers 114 operates as a controlled water redistribution network. Each sprinkler 114 is fluidly connected to the container 113 through pressure-regulated pipelines and electronically actuated solenoid valves.

[0048] When activated by the control unit, filtered water is directed through the pressure-regulated pipelines to individual heads of the sprinkler 114 designed with adjustable nozzles for precise spray patterns. The nozzles regulate droplet size, spray angle, and discharge rate to ensure uniform surface wetting or targeted irrigation of roadside vegetation. The control unit adjusts the sprinkler 114 activation based on real-time data such as moisture levels, weather conditions, and vegetation needs. The coordinated activation sequence enables zonal distribution, optimizing water usage while preserving pavement integrity, supporting vegetation health, and maintaining overall environmental sustainability.

[0049] The sprinklers 114 are directionally adjustable via an integrated swivel joint 115, activated at predefined intervals to spray filtered water toward roadside vegetation to support ecological sustainability, and spray the road surface to reduce temperature and minimize heat-induced deformation. The integrated swivel joint 115 functions as a precision rotational interface between each heads of the sprinkler 114 and its supply conduit, enabling controlled directional adjustment. The swivel joint 115 comprises a sealed rotary coupling with corrosion-resistant bearings and elastomeric O-rings to prevent leakage while allowing smooth angular movement. A compact electric micro-motor drives the rotational shaft based on predefined control signals from the central unit. The swivel joint 115 permits calibrated horizontal and vertical angular displacement, ensuring accurate targeting of either roadside vegetation or the pavement surface. Internal locking arrangement maintain the selected orientation during water discharge to preserve spray accuracy. By executing pre-defined rotation intervals, the swivel joint 115 enables systematic coverage, facilitating thermal regulation of the road surface and sustainable irrigation of adjacent vegetation.

[0050] An LED (Light Emitting Diode) array 116 is integrated around the mobile body 103 to provide illumination during repair operations to alert approaching vehicles. The LED array 116 operates as an active visual warning and operational status indicator during repair activities. The LED array 116 consists of high-intensity, weather-resistant LEDs mounted on a durable printed circuit board and enclosed within an impact-resistant transparent housing. Each LED is electrically connected to the control unit and controlled through a programmable driver circuit that regulates current, brightness, and flashing patterns. During maintenance operations, the control unit activates predefined illumination sequences, such as flashing or pulsating modes, to enhance visibility for approaching vehicles under varying light and weather conditions. Thermal management components, including heat sinks and conductive substrates, dissipate excess heat, ensuring reliable performance, energy efficiency, and extended operational lifespan.

[0051] A communication module integrated with the column 101, the module comprising Bluetooth Low Energy (BLE) beacon modules that establish a decentralized mesh network between adjacent street light poles for real-time sharing of road condition, repair activity, and environmental alert data. The Bluetooth Low Energy beacon module operates as a low-power, continuously active communication node that forms part of a decentralized mesh network supporting the autonomous road surface maintenance system. Internally, the Bluetooth Low Energy beacon module comprises a BLE SoC (System-on-Chip) with the control unit, RF transceiver, antenna, power management circuitry, and secure memory for firmware and data buffering.

[0052] The control unit interfaces with the sensors that are embedded in or near the roadway. Collected data is locally processed using embedded protocols to classify road anomalies, maintenance activity status, and hazard levels. The protocol used is a Kalman Filters. The Bluetooth Low Energy transceiver periodically broadcasts encrypted advertisement packets containing summarized status data and listens for incoming packets from neighboring poles. Using managed flooding or relay-based mesh protocols, each Bluetooth Low Energy (BLE) beacon module validates, timestamps, and forwards relevant packets, ensuring redundancy and low-latency communication across the network. The mesh network enables predictive alert propagation, with upstream poles receiving data from downstream repair zones and sequentially transmitting alerts to inform approaching vehicles in advance of affected sections.

[0053] A holographic projection unit 117 is mounted on the column 101 to display spatial virtual warning indicators ahead of active repair or hazardous zones. The holographic projection unit 117 operates by generating three-dimensional virtual warning indicators in the air ahead of active repair zones. The holographic projection unit 117 comprises a laser-based light source, beam shaping optics, spatial light modulators, and a projection control processor. The laser beams are modulated and diffracted through optical elements to create interference patterns that form visible holographic images at predetermined distances. The control unit synchronizes projection intensity, image geometry, and positioning based on programmed safety parameters. The holographic projection unit 117 display dynamic symbols such as warning signs, directional arrows, or hazard boundaries.

[0054] A Vehicle-to-Infrastructure (V2I) communication module is integrated with the column 101 to transmit real-time alerts to nearby connected vehicles. The Vehicle-to-Infrastructure communication module continuously gathers processed inputs from onboard sensors such as LiDAR module 106, thermal camera 102, radar module, and the hyperspectral scanner 107 that detect potholes, cracks, debris, surface wear, temperature, and moisture levels. The control unit analyzes the data in real time and formats the data into standardized Vehicle-to-Infrastructure messages using protocols such as Dedicated Short-Range Communications (DSRC) for transmission to nearby connected vehicles and traffic management systems.

[0055] The Vehicle-to-Infrastructure alerts include road condition warnings, lane closure notifications, diversion guidance, and recommended speed limits based on real-time road and traffic conditions, and the control unit dynamically adjusts alert intensity and range based on traffic density and vehicle speed. The Vehicle-to-Infrastructure communication module includes a transceiver, signal encoder, secure encryption layer, and antenna array to ensure low-latency, reliable communication within a defined radius. Additionally, the Vehicle-to-Infrastructure communication module continuously monitors network strength and system health to maintain uninterrupted safety communication during maintenance operations.

[0056] A battery (not shown in figure) is associated with the system to supply power to electrically powered components which are employed herein. The battery is comprised of a pair of electrode named as a cathode and an anode. The battery uses a chemical reaction of oxidation/reduction to do work on charge and produce a voltage between their anode and cathode and thus produces electrical energy.
