Description:FIELD OF THE INVENTION

[0001] The present invention relates to an adaptive road safety system designed to enhance road safety by actively responding to vehicle behavior and surrounding conditions to control vehicle speed, improve traffic flow, and reduce accident risks through real-time adjustments based on monitored parameters.

BACKGROUND OF THE INVENTION

[0002] With increasing urbanization and rising vehicular movement, road safety has become a significant concern. Fixed physical traffic control devices such as speed bumps and static signage are no longer sufficient to address dynamic traffic conditions, over-speeding risks, and real-time decision-making needs. Road safety faces multiple challenges including over-speeding, lack of real-time traffic control, and inadequate response to changing environmental conditions. Fixed speed breakers and signs fail to adapt to varying traffic situations, often causing discomfort or accidents, especially for emergency vehicles. Poor visibility, weather changes, and insufficient communication between road infrastructure and drivers further increase risks. Additionally, there is limited data collection on vehicle behavior, which hampers informed traffic management. Unauthorized speeding, sudden braking, and poor enforcement of rules also contribute to road hazards.

[0003] Traditionally, road safety has relied on static solutions such as permanent speed breakers, road signs, lane markings, and traffic signals. While effective in basic traffic management, these methods are limited in addressing real-time risks, fail to adapt to varying traffic or environmental conditions, and do not differentiate between compliant and non-compliant drivers. Additionally, they offer no mechanism for real-time data gathering or active surface control. These limitations make them unsuitable for today’s rapidly evolving traffic ecosystems where dynamic control and real-time feedback are essential.

[0004] US5509753A discloses a motorized retractable speed bump or warning device wherein the raising and lowering of the retractile is controlled by multiple remote means from signals generated by traffic conditions. The motorized retractable speed bump, wherein a retractile comprising of bi-folding hinged plates, which are elevated to present a visible obstruction to motor vehicles, and a position restraining device, operated by rotary and or linear motor drive means, by on/off manual push button switching, or through a series of Programmable Logic Controllers, by way of analogue or digital signals emanating from permanently mounted speed detecting devices.

[0005] US7967526B2 discloses a device reducing speed of vehicles travelling on a roadway, formed by at least one strip of flexible material, rubber or other similar material, made up of several hollow chambers which are interconnected by a calibrated conduit which enables the controlled passage of the fluid filling said chambers from that flattened by the wheel of the vehicle towards the adjacent chamber. The fluid contained therein is water, or a non-Newtonian fluid offering the higher viscosity, the higher the stress gradient applied thereto is, the fluid itself acting as means for controlling the resistance to deformation of the strip as the higher is the speed of impact of the vehicle in said strip.

[0006] Conventionally, many systems have been developed to manage road safety, however systems mentioned in prior art have limitations pertaining to selectively allow uninterrupted passage for authorized or compliant vehicles, and depend on external power sources and lack sustainable energy usage. Additionally, the existing systems fail to dynamically adjust the road surface to deter over-speeding, and do not offer real-time interaction with drivers or vehicles, making them less effective in high-risk or rapidly changing traffic environments.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a system that is capable of physically adapting to vehicle speed and type, selectively controlling passage, and visually communicating with drivers. Additionally, the system should capable of leveraging renewable energy from road activity and natural sources to ensure consistent and eco-friendly operation, enhancing both safety and sustainability.

[0009] An object of the present invention is to develop a system that is capable of automatically managing road safety by adjusting the surface level based on vehicle behavior and surrounding conditions.

[0010] Another object of the present invention is to develop a system that is capable of reducing the speed of over speeding vehicles by creating a physical response on the road surface.

[0023] 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.

[0024] The present invention relates to an adaptive road safety system developed for improving safety on roads by continuously analyzing vehicle activity and environmental factors, enabling timely adjustments that help control speed, streamline traffic movement, and reduce the likelihood of collisions.

[0025] Referring to Figure 1 and 2, an isometric view of an adaptive road safety system and a perspective view of a multi-lane roads associated with the system are illustrated, respectively, comprising a platform 101 installed with a curved plate 102, a pair of height-adjustable assembly 103 connected with the plate 102 and with the platform 101, a motorized drawer arrangement 104 coupled with the curved plate 102, an energy harvesting unit comprises of piezoelectric panels 105 and dual-axis adjustable vertical-axis wind turbines 106, a holographic projection unit 107 mounted on the plate 102, and a plurality of high-intensity LED (Light Emitting Diode) strip lights 201 are installed before, on, and after the plate 102 platform 101.

[0026] The disclosed system herein comprises of a platform 101 affixed with a curved plate 102 onto the road surface to maintain mechanical stability and alignment under vehicular load. During operation, the platform 101 holds the curved plate 102 in a fixed lateral position, allowing vertical adjustments through a height-adjustable assembly 103 affixed with the plate 102 with the platform 101. The platform 101 ensures durable, uninterrupted interaction with passing vehicles, enabling continuous operation without dislodgement or structural failure under repeated traffic flow.

[0027] The curved plate 102 fixed over the platform 101 functions as the primary contact surface for passing vehicles. When vehicles traverse the plate 102, the microcontroller detects and responds to surface interactions such as impact, load, or movement patterns. The curved design enables even distribution of vehicle weight while allowing elevation adjustments by the height-adjustable assembly 103. The plate 102 maintains contact integrity under dynamic traffic and transfers real-time data captured from its surface to the microcontroller. Based on vehicle parameters, the microcontroller actuates the plate 102 to raised or lowered for creating a dynamic physical response aimed at influencing vehicle behavior, especially speed modulation.

[0028] The pair of height-adjustable assembly 103 dynamically adjusting the height of the plate 102. The height-adjustable assembly 103 comprises mechanical actuators and structural connectors integrated between the platform 101 and the curved plate 102. The assembly 103 receives input signals from an inbuilt microcontroller, including vehicle speed, type, or traffic density. Upon signal reception, the assembly 103 activates vertical movement to raise or lower the curved plate 102 accordingly. The adjustment modifies the road surface elevation in real-time to deliver physical feedback to vehicles, particularly over speeding ones.

[0029] A plurality of embedded sensors is configured on the plate 102 and function to continuously collect real-time operational and environmental data pertaining to vehicular movement and surrounding conditions. These sensors transmit signals to the microcontroller, which interprets the input for decision-making processes. The sensors operate in synchronization to detect vehicle parameters such as speed, type, and weight, as well as external parameters including surface water levels, traffic flow, and object proximity. The microcontroller uses the interpreted sensor data to dynamically adjust the positioning of the plate 102 via the height-adjustable assembly 103, enabling adaptive surface control based on detected environmental and vehicular conditions. The embedded sensors include not limited to weight sensors, proximity sensors, ultrasonic sensors, LiDAR (Light Detection and Ranging) sensors, and cameras.

[0030] The weight sensors are embedded within the structural surface of the plate 102 and are operative to measure the load exerted by a vehicle upon contact. Upon detection of vehicular presence, the sensors generate a corresponding electrical signal that varies proportionally with the weight of the vehicle. This signal is relayed to the microcontroller, which processes the data to determine whether the detected load exceeds a predefined threshold. The result is used to classify vehicle types and assess road surface stress, enabling the microcontroller to modulate the plate’s height or trigger safety responses in case of overweight or high-impact vehicular transit.

[0031] The proximity sensors are positioned along the plate 102 surface and surrounding regions to detect the presence and relative distance of nearby objects or approaching vehicles without physical contact. These sensors emit a continuous or pulsed signal, and any reflected wave from nearby objects is captured to determine distance and direction. The captured signal is converted into distance data, which is transmitted to the microcontroller. Upon processing, the microcontroller determines the spatial dynamics around the plate 102, assisting in identifying vehicle arrival, occupancy, and enabling appropriate actuation of the plate 102 for either elevation, retraction, or maintaining a neutral road surface profile.

[0032] Furthermore, the microcontroller processes input data from the proximity sensors to assess whether an approaching vehicle is operating within a predefined speed limit. Based on this assessment, the microcontroller controls the height-adjustable assembly 103 to perform one of the following actions:
a) If the vehicle is within the allowed speed range or is recognized as an emergency vehicle such as an ambulance, fire truck, or public transport bus the microcontroller maintains the plate 102 in a flat or low-profile position, allowing smooth and uninterrupted passage; and
b) If the vehicle is detected to be over speeding or identified as a heavy vehicle, such as a truck, the microcontroller activates the assembly 103 to raise the plate 102, compelling deceleration and enhancing road safety.

[0033] For multi-lane roads, separate platform 101 are installed on each lane, with each curved plate 102 independently controlled by the microcontroller. The microcontroller adjusts each plate’s height based on the vehicle behavior and traffic conditions detected specifically within the respective lane.

[0034] The ultrasonic sensors mounted on or near the plate 102 emit high-frequency sound waves toward the road surface and surrounding environment. When these waves encounter an object or liquid surface such as accumulated water, they reflect back to the sensor. The time interval between transmission and echo reception is used to calculate distance. The sensor continuously monitors the elevation of water above the plate 102, and when this level exceeds a predefined safety threshold, it transmits a signal to the microcontroller. The microcontroller then actuates the height-adjustable assemblies to lower or retract the plate 102, facilitating unhindered vehicular movement and effective surface water drainage.

[0035] The LiDAR sensors are configured to emit rapid pulses of laser light and measure the time taken for each pulse to reflect from a surface or object. This data is processed to construct a precise three-dimensional spatial map of the area surrounding the plate 102. The sensors enable the detection of vehicular contours, positioning, and speed based on reflective patterns. The real-time LiDAR data is transmitted to the microcontroller for analysis, allowing for identification of specific vehicle types and surrounding obstacles. Based on this data, the microcontroller actuates the plate’s height or form, optimizing road safety and vehicle compatibility under dynamic traffic scenarios.

[0036] The cameras integrated onto or near the plate 102 operate to capture real-time visual data of the vehicular and environmental conditions. The captured footage supports identification of vehicle type, license recognition, traffic density, and other behavioral parameters. The visual input can also be cross-referenced with sensor data to validate accuracy and ensure redundancy. In case of anomalies or predefined safety triggers, the microcontroller utilizes the visual information to determine suitable surface adjustments or to initiate alert protocols for traffic regulation or incident logging.

[0037] The cameras comprise of an image capturing arrangement including a set of lenses that captures multiple images of the vehicular and environmental conditions, and the captured images are stored within memory of the cameras in form of an optical data. The cameras also comprise of a processor that is fed with artificial intelligence protocols, such that the processor processes the optical data and extracts the required data from the captured images. The extracted data is further converted into digital pulses and bits and are further transmitted to the microcontroller.

[0038] The microcontroller processes the received data from the camera and determine vehicle type, license recognition, traffic density, and other behavioral parameters. The microcontroller operatively connected to the embedded sensors and the height-adjustable assembly 103, and configured to receive, analyze, and process real-time data obtained from the sensors, including but not limited to vehicle speed, weight, and surrounding environmental parameters. Based on the processed data, the microcontroller generates appropriate control signals to the height-adjustable assembly 103 for dynamically regulating the elevation or depression of the curved plate 102. This ensures adaptive surface modulation to optimize road safety and vehicular control in accordance with detected conditions.

[0039] The microcontroller functions by continuously receiving input data from multiple embedded sensors that measure vehicle speed, weight, and environmental conditions such as temperature or surface moisture. The microcontroller processes this data to evaluate the necessary response for the road surface. Upon determining that a height adjustment is required, the microcontroller sends corresponding control signals to the height-adjustable assembly 103. These signals initiate the actuation of the curved plate 102 to the calculated position. The microcontroller simultaneously monitors feedback from position sensors to ensure accurate alignment and modifies signals accordingly to maintain smooth and real-time plate 102 adjustment.

[0040] Upon receiving sensor data detecting vehicle speed, type, or road conditions, the microcontroller actuates a motorized drawer arrangement 104 coupled with the curved plate 102 to facilitate precise vertical displacement of the curved plate 102 with respect to the road surface. The motorized drawer arrangement 104 is integrated within the platform 101 structure and engages with the height-adjustable assembly 103 to maintain the defined arc curvature of the plate 102 during elevation or depression. The arrangement 104 ensures synchronized motion through electromechanical actuation, allowing responsive adjustment to vehicular input or environmental changes.

[0041] The structure enables accurate translation of control signals into linear motion, providing reliable positional stability during operation under varying load conditions. The drawer arrangement 104 consists of multiple plates that are overlapped to each other with a sliding unit, wherein upon actuation of the drawer arrangement 104 by the microcontroller, the motor in the sliding unit starts rotating a wheel coupled via a shaft in clockwise/anticlockwise direction providing a vertical movement to the plate 102 in the drawer arrangement 104 to extend and maintain consistent curvature of the plate 102 during the adjustment.

[0042] Based on the vehicle speed detected by the embedded sensors, the microcontroller activates a plurality of high-intensity LED (Light Emitting Diode) strip lights 201 configured before, on, and after the plate 102. The LED strip lights 201 provide dynamic visual communication to approaching drivers by displaying color-coded signals in real-time. The microcontroller governs the color change of the LED lights 201, wherein green color indicates compliance with the speed limit, yellow color warns of nearing the upper threshold, and red color flashing signifies over-speeding, which further triggers activation of the height-adjustable curved plate 102 for vehicular control and road safety enforcement.

[0043] The high-intensity LED strip lights 201 are activated through signals received from the microcontroller based on vehicle speed data collected by the sensors. As a vehicle approaches, the microcontroller scrutinizes an integrated database to compare the detected speed with a pre-determined threshold value stored in the database. The corresponding LED strips before, on, and after the plate 102 light up in a specific color to provide a visual cue to the driver. The LED strips are powered by a connected energy source and driven by a circuit that enables synchronized illumination in designated patterns. The lights 201 remain continuously active and responsive, ensuring real-time display changes according to variations in each vehicle’s detected behavior.

[0044] Upon detection by the microcontroller that an approaching vehicle is moving within the permissible speed limit, the microcontroller sends a signal to the LED control circuit to activate the green color mode across the plurality of LED strips. The green LEDs illuminate in a steady and visible pattern to assure the driver that no intervention or speed adjustment is necessary. This feedback enhances driver confidence and ensures uninterrupted passage over the platform 101. The LED controller maintains this green light until a change in speed is detected that exceeds the lower threshold, at which point it transitions to the yellow or red signal.

[0045] Upon exceeding the speed of the vehicle from pre-set upper speed threshold recorded by the sensors, the microcontroller processes this data and commands the LED controller to switch the LED strip lights 201 to yellow color. The yellow light serves as a cautionary visual alert, prompting the driver to reduce speed immediately. The transition to yellow color is managed by pulse-width modulation within the LED circuit, ensuring brightness remains consistent and the change is noticeable. This state is temporary and dynamically updated; if the vehicle slows down, the light reverts to green color, while further increase in speed causes the microcontroller to activate the red flashing alert.

[0046] When the detected vehicle speed exceeds the maximum permissible limit, the microcontroller activates the red flashing LED mode. It sends a pulse signal to the LED controller to flash the red LEDs in high-intensity bursts, providing a strong visual warning to the driver. The flashing sequence is executed at a frequency configured to attract immediate attention and indicate violation. Simultaneously, this over speed detection triggers activation of the curved plate 102 adjustment mechanism to initiate a physical response. The red flashing LEDs remain active until the microcontroller detects a reduction in speed below the threshold or the vehicle fully passes the platform 101 area. An energy harvesting unit operatively associated with the curved plate 102 and platform 101 structure, configured to generate and store renewable energy for autonomous powering of the system components.

[0047] The energy harvesting unit comprises piezoelectric panels 105 embedded within or adjacent to the plate 102 for converting mechanical pressure into electrical energy and a plurality of vertical-axis wind turbines 106 mounted near the platform 101. The turbines 106 are equipped with dual-axis actuators to adjust yaw and pitch angles in response to real-time wind data detected by integrated wind sensors and anemometers. The harvested energy is routed to power illumination modules, sensors, control systems, and other electronic assemblies of the platform 101.

[0048] The energy harvesting unit operates by collecting mechanical and wind energy from vehicular and environmental activity. When a vehicle passes over the platform 101, pressure applied to the embedded piezoelectric panels 105 generates voltage that is captured and stored in connected batteries. Simultaneously, wind created by vehicle movement or ambient flow activates the vertical-axis wind turbines 106. The real-time wind data is processed to adjust turbine orientation and blade pitch for maximum efficiency. The combined electrical output from both sources is directed to a central energy storage unit, which subsequently powers the sensors, control electronics, lighting elements integrated into the road safety platform.

[0049] The piezoelectric panels 105 embedded within or around the speed breaker surface generate electricity by converting the mechanical strain exerted by passing vehicles into electrical charge. Each time a vehicle applies pressure on the plate 102, the deformation in the piezoelectric material generates a voltage, which is collected through a circuit and regulated for charging a connected battery or capacitor. The microcontroller captures successive mechanical impulses with minimal delay, enabling continuous energy harvesting from traffic flow.

[0050] The vertical-axis wind turbines 106 activate upon detecting wind flow caused by passing vehicles or natural conditions. Each turbine includes dual-axis actuators allowing dynamic adjustment of yaw (horizontal alignment) and pitch (blade angle) based on wind direction and velocity data received from integrated anemometers and weather sensors. The microcontroller uses this data to continuously optimize turbine positioning for maximum energy output. When wind speeds exceed safe operational thresholds, the microcontroller automatically initiates shutdown procedures or adjusts blade angles to prevent structural damage.

[0051] For detecting the precise geographic coordinates of the platform 101, a GPS (Global Positioning System) module integrated with the microcontroller. The microcontroller utilizes this positional data to reference stored zone-specific criteria, including speed regulations and traffic norms, and adjusts the height of the curved plate 102 accordingly to comply with the defined standards of the identified location. The GPS module continuously retrieves satellite-based positional data and transmits the coordinates to the microcontroller.

[0052] Upon receiving the current geographic location, the microcontroller cross-references it with an onboard database containing predefined zone-specific criteria such as school zones, accident-prone areas, or speed-regulated zones. Based on the matched criteria, the microcontroller generates adjustment commands to the height-adjustable assembly 103 to raise or lower the curved plate 102 as per localized safety requirements. The GPS module operates in real time, ensuring constant positional awareness and allowing the microcontroller to proactively enforce appropriate surface-level responses tailored to specific geographic contexts.

[0053] Based on sensor data and vehicle behavior, the microcontroller activates a holographic projection unit 107 installed on the curved plate 102 to project real-time visual messages and warnings directly onto the road surface or within the driver’s line of sight. The messages are determined based on live sensor inputs and vehicle behavior, dynamically updated to reflect real-time changes in speed, traffic density, or environmental conditions, thereby promoting proactive driver engagement and compliance.

[0054] The holographic projection unit 107 operates by receiving control commands from the microcontroller, which processes sensor data including vehicle speed, traffic density, and environmental conditions. Based on this data, the microcontroller determines the appropriate message and transmits the content to the projection unit 107. The projection unit 107 uses laser or light-based projection technology to display clear, visible messages on or above the road surface. These messages are dynamically modified in real time, adapting instantly to changing vehicular or environmental conditions. The projection unit 107 ensures that drivers receive timely and context-relevant warnings or acknowledgments to promote compliant and safe driving behavior. the messages include, but are not limited to:
a) “Slow Down – Speed Breaker Ahead”;
b) “You Are Over Speed – Risk of Fine”;
c) “Safe Speed – Thank You!”;

[0055] Moreover, the microcontroller is equipped with an integrated communication module configured to establish secure, real-time data exchange with external traffic management centers. This communication facilitates continuous remote monitoring of road and traffic conditions, transmission of system status updates, and immediate relay of emergency notifications. The module supports bidirectional communication protocols to enable both reception of external directives and transmission of internal sensor data.

[0056] This integration allows centralized control and timely intervention by relevant authorities, enhancing overall traffic management efficiency and responsiveness to dynamic roadway situations. The communication module operates by establishing a wireless connection, includes but is not limited to a GSM (Global System for Mobile Communication) module, a Wi-Fi (Wireless Fidelity) module, or a Bluetooth module which is capable of establishing a wireless network between the microcontroller and external traffic management centers.

[0057] The module continuously transmits sensor data, system status, and environmental conditions to the control centers. The module also receives remote commands and configuration updates, which the microcontroller processes to adjust system parameters. In the event of an emergency, the module instantly sends alert notifications to authorized personnel. The communication module manages data encryption and error checking to maintain secure and reliable data transfer, ensuring consistent real-time coordination between the road safety system and external monitoring authorities.

[0058] Lastly, a battery is associated with the system to supply power to electrically powered components which are employed herein. The battery is comprised of a pair of electrodes known as a cathode and an anode. A voltage is generated between the anode and cathode via oxidation/reduction and thus produces the electrical energy to provide to the system.

[0059] The present invention works best in the following manner, where the system comprises the curved plate 102, the height-adjustable assembly 103, and the embedded sensors. The microcontroller receives continuous real-time input from the embedded sensors including the weight sensor, the proximity sensor, the ultrasonic sensor, the LiDAR sensor, and the camera. Based on the collected data from the sensors and the cameras, the microcontroller identifies vehicle speed, type, weight, and prevailing environmental and traffic conditions. When a vehicle is detected to be within the prescribed speed limit or identified as an emergency vehicle, the microcontroller maintains the curved plate 102 in a flat or low-profile position. In contrast, when the vehicle is detected to be over-speeding or categorized as a heavy vehicle, the microcontroller directs the height-adjustable assembly 103 and the motorized drawer arrangement 104 to raise the curved plate 102, thereby prompting deceleration. If the ultrasonic sensor detects water levels exceeding a safety threshold, the microcontroller retracts the plate 102 into the platform 101 to facilitate drainage and avoid obstruction. Additionally, the microcontroller manages visual signaling through the high-intensity LED strip lights 201 and controls the holographic projection unit 107 to display warnings. The energy harvesting unit powers the system, while the communication module enables integration with traffic management centers.
