BACKGROUND OF THE INVENTION
The following description of related art is intended to provide background information pertaining to the field of the disclosure. This section may include certain aspects of the art that may be related to various features of the present disclosure. However, it should be appreciated that this section be used only to enhance the understanding of the reader with respect to the present disclosure, and not as admissions of prior art.

Urban traffic congestion is a growing problem worldwide, exacerbated by increasing vehicle numbers, limited road infrastructure, and inefficient traffic management practices. Traditional traffic management systems often rely on fixed timing of traffic signals and manual interventions, which are insufficient to adapt to real-time variations in traffic patterns. As a result, road networks experience frequent bottlenecks, leading to longer travel times, increased fuel consumption, and higher levels of air pollution.

The advent of new technologies, including sensor networks, the Internet of Things (IoT), and data analytics, has introduced the possibility of more dynamic and intelligent traffic management systems. These technologies enable the collection of real-time data from various sources such as traffic cameras, loop detectors, GPS devices, and even mobile phones. However, the challenge lies in processing and analyzing this vast amount of data effectively to make timely and accurate decisions for traffic control.

Existing traffic management solutions that incorporate data analytics often face limitations in scalability, accuracy, and responsiveness. Many systems rely on historical data for decision-making, which may not reflect current traffic conditions accurately. Additionally, these solutions may not be equipped to handle unexpected traffic incidents, such as accidents or sudden changes in weather, which can drastically affect traffic flow.

To address these issues, there is a need for a comprehensive traffic management system that not only collects real-time data but also analyzes it using advanced machine learning techniques. Such a system can predict traffic congestion, optimize traffic signals dynamically, and provide timely updates to drivers, thereby significantly enhancing the efficiency of urban road networks.

The present invention provides a comprehensive smart traffic management system designed to enhance the efficiency of urban road networks by utilizing real-time data analytics and advanced machine learning techniques. The system is built on a robust architecture that integrates various data sources, such as traffic sensors, cameras, GPS devices, and vehicle-to-infrastructure (V2I) communication interfaces. These components work together to collect and analyze traffic data, allowing for dynamic adjustments in traffic control strategies.

The system comprises several key modules, starting with the Data Collection Module, which is responsible for gathering real-time information from a diverse set of sensors deployed across the urban road network. These sensors include inductive loop detectors for vehicle count, CCTV cameras for visual monitoring, radar sensors for speed measurement, and GPS data from vehicles. Additionally, the system can incorporate external data inputs, such as weather conditions, roadworks schedules, and public event timings, to provide a comprehensive view of factors affecting traffic flow.

Next, the Data Analytics Engine processes the collected data using machine learning algorithms. This engine employs techniques like deep learning, neural networks, and predictive analytics to identify traffic patterns, detect anomalies, and predict congestion. By continuously analyzing real-time data alongside historical traffic data, the system can forecast traffic conditions and potential bottlenecks with high accuracy. This predictive capability enables proactive traffic management, where adjustments can be made before congestion escalates.

The Dynamic Traffic Control Module is a crucial part of the invention, allowing for real-time adjustments in traffic signal timings, lane directions, and speed limits based on the insights provided by the analytics engine. The module uses optimization algorithms, such as reinforcement learning, to determine the most efficient configuration of traffic signals and lane allocations. For instance, during peak hours or special events, the system can implement adaptive signal control, extending green light durations for high-traffic routes while minimizing delays on less congested roads.

An integral feature of the system is its V2I Communication Interface, which facilitates real-time information exchange between the traffic management system and connected vehicles. This interface allows the system to send live updates, congestion alerts, and rerouting instructions to drivers through mobile apps, navigation systems, or in-car displays. By providing this information directly to road users, the system helps reduce traffic congestion, as drivers can make informed decisions about alternative routes and avoid congested areas.

The invention also incorporates a Cloud and Edge Computing Architecture to enhance its scalability and responsiveness. Edge computing nodes are deployed at key locations in the road network to handle real-time data processing, minimizing latency and enabling quick responses to sudden changes in traffic conditions. Meanwhile, cloud servers are used for data storage, model training, and long-term analytics, allowing for continuous improvement of the machine learning models based on new data.

In the first embodiment, the invention is implemented as an Adaptive Traffic Signal Control System for a busy urban intersection. The system utilizes a combination of CCTV cameras and inductive loop sensors installed at the intersection to collect real-time data on vehicle count, speed, and traffic density. This data is fed into the analytics engine, which uses a reinforcement learning algorithm to predict traffic congestion and adjust signal timings dynamically.

For instance, if the system detects a high volume of vehicles approaching from one direction, it can extend the green light duration for that lane while shortening the red light duration for the opposing lanes. This adaptive control helps to minimize stop-and-go traffic, reduce vehicle idling times, and improve the overall flow through the intersection. Additionally, the system can prioritize certain vehicles, such as emergency services or public transport, by adjusting the traffic signals to provide a faster route through congested areas.

The second embodiment focuses on a Real-Time Traffic Rerouting System integrated across a city's main road network. This embodiment leverages GPS data from connected vehicles and mobile navigation apps to monitor traffic conditions across various routes in real time. The system analyzes the data to identify congested areas and potential traffic jams.

Upon detecting congestion, the system uses machine learning models to predict the duration and impact of the traffic jam. It then calculates alternative routes for affected vehicles, considering factors such as road capacity, travel time, and current traffic conditions. Through the V2I communication interface, the system sends rerouting suggestions directly to drivers via their navigation apps. For instance, if a major accident occurs on a highway, the system can quickly redirect vehicles to secondary roads or less congested routes, minimizing delays and preventing further congestion buildup.

In both embodiments, the use of real-time data analytics and machine learning allows the system to respond proactively to traffic conditions, improving overall traffic flow, reducing travel times, and enhancing the safety and efficiency of urban road networks. These embodiments showcase the versatility of the invention, demonstrating its applicability to various urban traffic scenarios and its potential for widespread implementation in smart city infrastructures.

While considerable emphasis has been placed herein on the preferred embodiments, it will be appreciated that many embodiments can be made and that many changes can be made in the preferred embodiments without departing from the principles of the invention. These and other changes in the preferred embodiments of the invention will be apparent to those skilled in the art from the disclosure herein, whereby it is to be distinctly understood that the foregoing descriptive matter to be implemented merely as illustrative of the invention and not as limitation.
