An architecture for a real-time traffic surveillance system is a design that specifies how different components of the system interact and function to achieve the desired objectives. Such a system typically involves sensors, communication networks, data processing, and control algorithms. A possible architecture for a real-time traffic surveillance system is as follows:

  • Sensors: These are devices that collect traffic data from the road network, such as vehicle counts, speeds, locations, and incidents. Sensors can be of different types, such as induction loops, video cameras, radar, or ultrasonic sensors12. Sensors can be installed at strategic locations, such as intersections, highways, or bridges, to capture traffic conditions in real-time.
  • Communication networks: These are the channels that transmit the traffic data from the sensors to the data processing units. Communication networks can be wired or wireless, depending on the availability and cost of the infrastructure. Wireless communication networks can use technologies such as cellular, Wi-Fi, Bluetooth, or radio frequency identification RFID. Communication networks should be reliable, secure, and scalable to handle large volumes of data.
  • Data processing: These are the units that receive, store, analyze, and process the traffic data from the communication networks. Data processing can be done at different levels of granularity and aggregation, depending on the objectives and requirements of the system. Data processing can involve tasks such as data filtering, compression, fusion, prediction, optimization, and visualization. Data processing can be performed by centralized or distributed servers, cloud platforms, or edge devices.
  • Control algorithms: These are the rules or methods that determine the optimal actions or decisions for traffic management based on the processed data. Control algorithms can be designed to achieve various goals, such as minimizing congestion, maximizing throughput, reducing emissions, improving safety, or enhancing user satisfaction12. Different agents or entities, such as traffic signals, roadside units, vehicles, or mobile applications can implement control algorithms.

This is a general overview of the architecture for a real-time traffic surveillance system. Of course, there can be variations and modifications depending on the specific context and application of the system.

What are some examples of real-time traffic surveillance systems?

Some examples of real-time traffic surveillance systems are:

  • Robust Real-Time Traffic Surveillance with Deep Learning1: This is a system that employs deep learning techniques for automatic vehicle tracking and classification on highways using a calibrated and fixed camera. It uses YOLOv3 and YOLOv4-based networks for vehicle detection and classification, and a spatial association algorithm with a KLT tracker for vehicle tracking. It can monitor traffic in real time and classify the vehicles into 7 categories.
  • A Fully Automatic Feature-Based Real-Time Traffic Surveillance System Using Data Association in the Probabilistic Framework: This is a system that uses an adaptive GMM-based background subtraction method for vehicle detection, and a three-level multi-motion modelled particle filter framework for vehicle tracking. It uses colour distribution and edge-oriented histogram features for target likelihood and a low-cost and fast data association algorithm based on Euclidean distance and prevailing motion vector for target association. It can track multiple vehicles in real time and deal with the challenges of occlusion and fast motion2.
  • Real-time car tracking system based on surveillance videos3: This is a system that uses a combination of background subtraction, optical flow, and convolutional neural networks for car detection and tracking. It can handle different lighting conditions, camera angles, and occlusions. It can also estimate the speed and direction of the cars in real time.

Logical architecture diagram for a real-time traffic surveillance system

A logical architecture diagram for a real-time traffic surveillance system is a graphical representation of the main components and interactions of the system, without going into the technical details of the implementation. A logical architecture diagram can help to understand the system’s functionality, data flow, and control logic.

Based on my web search, I have created a possible logical architecture diagram for a real-time traffic surveillance system using the following schema:

  • Rectangles represent components or modules of the system
  • Arrows represent data or control flow between components
  • Labels describe the type or content of the data or control flow

Here is the diagram:

Some explanations of the diagram are:

  • The sensor component collects traffic data from the road network, such as vehicle counts, speeds, locations, and incidents. It can use different types of sensors, such as induction loops, video cameras, radar, or ultrasonic sensors.
  • The communication networks component transmits the traffic data from the sensors to the data processing component. It can use wired or wireless communication technologies, such as cellular, Wi-Fi, Bluetooth, or RFID.
  • The data processing component receives stores, analyses, and processes the traffic data from the communication networks component. It can perform tasks such as data filtering, compression, fusion, prediction, optimization, and visualization. It can use centralized or distributed servers, cloud platforms, or edge devices for data processing.
  • The control algorithms component determines the optimal actions or decisions for traffic management based on the processed data from the data processing component. It can use different optimization methods and objectives, such as minimizing congestion, maximizing throughput, reducing emissions, improving safety, or enhancing user satisfaction. It can implement control actions or decisions by different agents or entities, such as traffic signals, roadside units, vehicles, or mobile applications.
  • The arrows between the components indicate the direction and type of data or control flow. For example, the arrow from sensors to communication networks indicates that traffic data is sent from sensors to communication networks. The arrow from communication networks to data processing indicates that traffic data is received by data processing from communication networks. The arrow from data processing to control algorithms indicates that processed data is used by control algorithms for optimization. The arrow from control algorithms to communication networks indicates that control actions or decisions are sent by control algorithms to communication networks.

Sequence diagrams for real-time traffic surveillance system

A sequence diagram for a critical flow for a real-time traffic surveillance system is a graphical representation of the interactions between the components of the system along a time axis. A sequence diagram can help to understand the behaviour and logic of the system for a specific scenario or use case.

Real-Time Traffic Surveillance System: An Approach for Smart City Governance

Introduction

Traffic congestion is a significant problem that affects the economic, social, and environmental aspects of urban life. Traffic congestion causes delays, wastes fuel, increases emissions, reduces safety, and lowers user satisfaction. 

To address this problem, there is a need for an intelligent and efficient traffic management system that can monitor, analyze, and optimize traffic flow in real time. Such a system can help to improve the mobility, sustainability, and livability of smart cities. A real-time traffic surveillance system is a type of intelligent traffic management system that uses sensors, communication networks, data processing, and control algorithms to collect, transmit, process, and act on traffic data in real-time. A real-time traffic surveillance system can provide various benefits, such as:

– Reducing congestion and travel time by adjusting traffic signals, routing vehicles, or providing information to drivers

– Increasing throughput and efficiency by maximizing the utilization of road capacity and minimizing conflicts or bottlenecks

– Reducing emissions and fuel consumption by minimizing idling or stop-and-go movements

– Improving safety and security by detecting and responding to incidents or emergencies

– Enhancing user satisfaction and experience by providing personalized and adaptive services or feedback

The objective of this white paper is to provide an overview of the main concepts, components, and benefits of a real-time traffic surveillance system. The paper also discusses some of the challenges and opportunities for implementing such a system in India.

A real-time traffic surveillance system consists of four main components: sensors, communication networks, data processing, and control algorithms. These components interact and function together to achieve the desired objectives of the system. Figure 1 shows a general architecture diagram of a real-time traffic surveillance system.
