Specification

Description:FIELD OF DISCLOSURE
The present disclosure relates to the field of blockchain technology and traffic management, more particularly to blockchain-based intelligent traffic management.
DEFINITIONS
As used in the present disclosure, the following terms are generally intended to have the meaning as set forth below, except to the extent that the context in which they are used indicates otherwise.
Emergency Vehicle: The term 'Emergency Vehicle' mentioned in the present disclosure refers to any specialized vehicle, such as an ambulance, a fire truck, and police vehicles, or any other vehicle requiring prioritized passage on the road designed for urgent response to emergencies or critical situations. These vehicles often require prioritized passage in traffic due to time-sensitive and potentially life-saving reasons, such as transporting patients, extinguishing fires, or addressing public safety threats.
Regular Vehicle: The term 'Regular Vehicle' mentioned in the present disclosure refers to standard, non-emergency vehicles used for everyday transportation by individuals, businesses, and organizations.
Roadside Units: The term 'Roadside Units mentioned in the present disclosure refers to stationary infrastructure components within the Internet of Vehicles (IoV) ecosystem that facilitate communication between emergency vehicles (EVs), regular vehicles, and traffic management systems. They act as intermediaries, enabling vehicle-to-infrastructure (V2I) communication to ensure secure and efficient data exchange. RSUs play a critical role in verifying vehicle identities, relaying real-time traffic updates, and coordinating traffic signal adjustments to prioritize the passage of emergency vehicles, while maintaining overall traffic flow and safety.

BACKGROUND
The background information herein below relates to the present disclosure but is not necessarily prior art.
Emergency vehicles (EVs) play a vital role in ensuring public safety, yet their ability to navigate urban traffic efficiently remains a persistent challenge. Congested roads, uncoordinated traffic signals, and the lack of real-time communication between vehicles and traffic management systems lead to significant delays, jeopardizing timely responses during emergencies. The absence of a streamlined mechanism to grant priority passage for EVs often results in disruptions not only to emergency responses but also to regular traffic, creating chaotic and unsafe conditions. As urban areas continue to expand and traffic density increases, the need for a robust system to address these challenges has become more critical than ever.
While several existing systems attempt to improve EV passage, they are inherently limited by the lack of integrated security, vehicle authentication, and real-time communication protocols. For instance, solutions like neural network-based siren detection or real-time traffic signal adjustments focus on optimizing traffic flows but do not address the authentication of EVs to prevent unauthorized access to priority features. Moreover, systems reliant on IoT or GPS tracking often lack secure data exchange mechanisms, leaving them vulnerable to cyber threats and potential misuse. Additionally, most existing models fail to account for varying traffic conditions or prioritize EVs based on urgency, leading to inefficiencies in complex urban environments.
Therefore, there is a need for a system for prioritizing and routing emergency vehicles in an Internet of Vehicles (IoV) environment.

Emergency vehicles (EVs) are essential for public safety, yet their ability to navigate urban traffic is hindered by congestion, uncoordinated signals, and insufficient real-time communication with traffic systems, causing critical delays during emergencies. Existing solutions, such as siren-based detection and traffic signal adjustments, partially address these issues but lack comprehensive integration, secure communication protocols, and reliable vehicle authentication, leaving them vulnerable to misuse and cyber threats. As urban traffic density grows, the urgency for a robust, secure, and adaptable system that prioritizes EVs based on urgency and efficiently mitigates traffic challenges has become paramount.
To address the issues of the existing systems and methods, the present disclosure envisages a system for prioritizing and routing emergency vehicles in an IoV environment (hereinafter referred to as "system 100") and a method for prioritizing and routing emergency vehicles in an IoV environment (hereinafter referred to as "method 200"). The system (100) will now be described with reference to Figure 1, and Figure 2, and the method (200) will be described with reference to Figures 3A, and 3B.
Figure 1 illustrates a block diagram representing a system for prioritizing and routing emergency vehicles in an IoV environment in accordance with one embodiment of the present disclosure. Referring to Figure 1 the system (100) comprises emergency vehicles (102) equipped with a unique digital identifier stored on a secure decentralized ledger of a blockchain network (104), IoV communication module (101), roadside unit (105), traffic management unit (106), verification module (106a), analysis module (106b), intelligent routing module (106c), and signal management module (106d).
The system (100) employs blockchain technology and real-time communication to enhance the efficiency of emergency vehicle routing while minimizing disruptions to general traffic flow.
The system (100) includes a plurality of emergency vehicles (102), each uniquely identified by a digital identifier stored on a secure decentralized ledger within a blockchain network (104). These emergency vehicles are equipped with Internet of Vehicles (IoV) communication modules (101), which are configured to transmit real-time data, such as the vehicle's location and priority status, and to initiate priority routing requests when required.
In addition, the system incorporates at least one roadside unit (105) to facilitate real-time communication between emergency vehicles (102), regular vehicles (103), and the traffic management unit (106). This roadside unit ensures seamless data exchange and coordination across the IoV network, enabling responsive traffic management decisions.
The traffic management unit (106) is a critical component of the system, encompassing multiple modules that work collaboratively to manage traffic and prioritize emergency vehicles. It includes an analysis module (106b) within the traffic management unit (106) processes real-time data to evaluate various parameters, such as current traffic conditions, the proximity of emergency vehicles to intersections, and their relative priorities. Based on this analysis, the system determines the optimal route for the verified emergency vehicles, ensuring that the most critical vehicles receive appropriate prioritization. It includes a verification module (106a) that utilizes smart contracts embedded in the blockchain network (104) to authenticate emergency vehicles. This verification involves validating the vehicle's identity against pre-authorized digital certificates stored on the blockchain, ensuring secure and tamper-proof identification of emergency vehicles before granting them priority.
Once the optimal route is identified, the intelligent routing module (106c) automates traffic control actions by executing smart contracts embedded in the blockchain network (104). The smart contract execution is conducted only for verified EVs. This module ensures that routing decisions are implemented across the IoV environment in real-time, enabling efficient navigation for emergency vehicles.
To further facilitate uninterrupted passage, the system includes a signal management module (106d) that dynamically adjusts traffic signals based on the routing decisions made by the intelligent routing module (106c). By synchronizing traffic signals with the determined optimal routes, this module reduces delays and ensures a clear path for emergency vehicles.
In an embodiment, the emergency vehicle data includes vehicle location, vehicle speed, vehicle direction, vehicle type, license plate number, and unique vehicle identification number.
In an embodiment, the priority routing request is configured to be initiated by the emergency vehicle (102) to the traffic management unit (106) in order to request an unimpeded passage on a route. The route is the path taken by a vehicle along its journey from origin to destination.
In an embodiment, the blockchain network (104) is configured to facilitate communication between the emergency vehicles (102), at least one roadside unit (105), and the traffic management unit (106).
In an embodiment, the pre-authorized digital certificates are issued by an authorized entity and are configured to verify the status of a vehicle as an emergency vehicle (102) by referencing a unique vehicle identification number stored on the blockchain network (104).
In an embodiment, the signal management module (106d) further comprises a real-time monitoring module (106e) integrated into the traffic control system to continuously update traffic signal configurations based on emergency vehicle movement.
In an embodiment, the smart contract is a self-executing code on the blockchain network (104) configured to prioritize the passage of the emergency vehicles (102) and to optimally route the traffic.
In another embodiment, the smart contract is configured to route the traffic based on real-time factors including proximity among the emergency vehicles (102), the arrival time of the emergency vehicles (102) at a predetermined location, distance to be travelled by each emergency vehicle (102), and priority of the routing request initiated by each emergency vehicle (102).
In an embodiment, the signal management module (106d) is configured to notify vehicles (102,104) in the vicinity of an emergency vehicle (102) to facilitate prioritized passage for the emergency vehicle along the route while approaching or passing through a predetermined location. The predetermined location is a location along the route of the emergency vehicle from its origin to its destination.
In an embodiment, the system (100) is configured to comprise a repository (b) configured to securely store and manage the digital identities of the emergency vehicles (102), priority routing requests from the emergency vehicles (102), and transaction records of the emergency vehicles (102) on the blockchain network (104).
In another embodiment, the roadside unit (105) is further configured to relay emergency vehicle data to the traffic management unit (106) and also to communicate with vehicles (102,103) in the vicinity of said emergency vehicle to enable dynamic traffic adjustments and ensure uninterrupted passage for emergency vehicles (102).
Figure 2 depicts a flowchart elucidating the working of the system for prioritizing and routing emergency vehicles in an IoV environment in accordance with one embodiment of the present disclosure. Initially, the EVs (102), each equipped with an IoV communication module (101), send a priority routing request to the Traffic Management Unit (106). The request is accompanied by real-time data such as vehicle location, speed, and priority status, which are transmitted securely via the blockchain network (104). The Traffic Management Unit (106) receives and processes these requests using its analysis module (106b), which evaluates the proximity of each EV to traffic junctions and other critical factors, such as current traffic conditions.
Next, the system determines whether more than one EV has requested priority. If only one EV is requesting priority, it is immediately granted clearance to pass through the junction without further analysis. However, if multiple EVs (102) are detected, the system calculates their estimated arrival times at the junction based on real-time data, such as speed and location. If multiple EVs are predicted to arrive at the same time, the system proceeds to evaluate the priority of each vehicle. If the priorities are identical, the EV with its destination farthest from the junction is prioritized to pass first, ensuring the most efficient passage of vehicles. If the priorities differ, the system allows the EVs to pass in descending order of priority and distance, thus optimizing the traffic flow and reducing delays.
Upon determining the appropriate routing, the system sends a verification request to the verification module (106a), which authenticates the EV's identity using pre-authorized digital certificates stored on the blockchain (104). If the request is verified as valid, the system triggers smart contracts executed by the intelligent routing module (106c), which automatically adjusts traffic signals via the signal management module (106d) to facilitate the unimpeded passage of prioritized EVs. This dynamic adjustment ensures that traffic signals are synchronized with the routing decisions in real time, clearing the path for the EVs and preventing delays.
Finally, once all prioritized EVs have passed, the system resumes normal traffic operations. Throughout the entire process, blockchain technology (104) ensures secure communication and transaction recording, providing a tamper-proof, decentralized ledger to track the identity and routing of emergency vehicles, thus guaranteeing the integrity of the traffic management system.

The order in which method 200 is described is not intended to be construed as a limitation, and any number of the described method steps may be combined in any order to implement method 200, or an alternative method. Furthermore, method 200 may be implemented by processing resource or computing device(s) through any suitable hardware, non-transitory machine-readable medium/instructions, or a combination thereof. The method 200 comprises the following steps:
At step 202, the method (200) includes transmitting, by an Internet of Vehicles (IoV) communication module (101) real-time emergency vehicle data, and initiating priority routing requests.
At step 204, the method (200) includes facilitating, by at least one roadside unit (105), real-time communication between emergency vehicles (102), regular vehicles (103), and the traffic management unit (106).

At step 208, the method (200) includes receiving, by a verification module (106a), the emergency vehicle data and verifying vehicle identity by pre-authorized digital certificates stored in the blockchain network (104).
At step 210, the method (200) includes automating, by an intelligent routing module (106c), traffic control actions based on the optimal route.
