The exponential growth in the number of vehicles on the road has outpaced the development of road infrastructure. As a result, people are spending more time traveling between the same destinations every year. Many cities continue to rely on traditional traffic signal systems that are either manually controlled or operate on fixed time schedules. Unfortunately, these conventional methods lack efficiency as they do not utilize real-time data to optimize traffic flow. One critical problem with these outdated systems is the inability to clear the path for emergency vehicles, such as ambulances, fire trucks, and police vehicles, especially during peak traffic hours. The manual operation of traffic signals is prone to errors, leading to increased fuel consumption and even health-related issues due to prolonged exposure to traffic. Additionally, these conventional systems often result in unequal traffic flow from different directions at a given time. It\'s evident that the existing traffic management methods are insufficient and outdated, and there\'s a pressing need to implement smarter and more efficient traffic control systems to address these issues

Introduction

I. INTRODUCTION

A smart traffic management system is in development, utilizing sensor data, communication, and automated algorithms to improve the flow of traffic. The objective is to optimally control the duration of green or red lights at specific intersections. Rather than having fixed green or red-light durations, the system will adapt based on the number of vehicles present. In heavy traffic, green lights will stay on longer, while in lighter traffic, red lights will have longer intervals. This solution aims to eliminate inefficiencies at intersections, reduce commuting costs, and minimize pollution.

Often, traffic flowing into an intersection from various directions is uneven, a factor ignored by conventional traffic management systems. This imbalance leads to air pollution and severe health issues, particularly in metropolitan cities like Bangalore, where the number of vehicles is substantial. A smart traffic management system addresses this by continuously assessing traffic from all directions at an intersection using sensors placed at regular intervals. The data is collected and processed by a control system, which calculates the optimal timing for green lights in each direction to prevent traffic congestion.

Another significant issue addressed in this project is the movement of emergency vehicles (fire engines, ambulances, and police vehicles) through congested intersections. Due to the lack of infrastructure to support the swift movement of emergency vehicles in cities, an autonomous system is proposed to aid their transit. This system identifies emergency vehicles using radio wave signalling. When an emergency vehicle is detected, an SOS signal is transmitted and detected by a signal detection unit, which triggers the traffic management system. The system identifies emergency vehicles about 1 kilometre from the signal, and when they are within 500 meters, the control unit activates a green signal in the approaching direction, ensuring a clear path and preventing vehicle congestion.

A priority order is established for different types of emergency vehicles: Ambulance, Fire truck, and Police vehicles. In the event of multiple emergency vehicles approaching from various directions, the system determines the order of precedence, ensuring priority for the direction with multiple emergency vehicles. This provides an autonomous and efficient way to clear a signal-free path for emergency vehicles, addressing the lack of infrastructure for their unobstructed movement.

In 2014, 54% of the global population resided in urban areas, with a projected annual growth of nearly 2% until 2020. This population density places significant pressure on transportation systems. The high cost of living in urban areas often leads to long commutes, further straining transportation networks.

III. LITERATURE SURVEY

The Internet of Things (IoT), sometimes referred to as the Internet of Everything (IoE), encompasses all web-enabled devices that gather, transmit, and act upon data acquired from their surroundings using embedded sensors, processors, and communication hardware. These devices, often denoted as "connected" or "smart" devices, can occasionally communicate with other related devices through a process known as machine-to-machine (M2M) communication and execute actions based on the information they exchange. While humans can interact with these gadgets to configure them, provide instructions, or access data, the devices operate autonomously with minimal human intervention. The development of IoT has been facilitated by the availability of compact mobile components and the constant connectivity provided by home and business networks. These connected devices generate substantial amounts of internet traffic, comprising extensive data that can be utilized to enhance device functionality and, at the same time, raises concern about privacy and security. The abundance of new data and the internet-accessible nature of these devices give rise to legitimate concerns regarding both privacy and security. Nevertheless, this technology offers real-time information to an unprecedented degree, enabling remote monitoring of homes and families for safety, process optimization in businesses for increased productivity, waste reduction, and the prevention of unforeseen downtime. Additionally, sensors integrated into city infrastructure contribute to the reduction of road congestion and early warnings about infrastructure deterioration. Furthermore, open-area gadgets can monitor shifting environmental conditions and provide timely alerts regarding potential disasters.
