How AI in Traffic Management is Helping to Ease Traffic Congestion

July 7, 2022

AI Road Traffic

The rapid advancement of artificial intelligence (AI) has brought about a sea change in road traffic management. AI can now predict and control the flow of people, objects, vehicles and goods at different points on the transportation network with great accuracy. In addition to providing better service for citizens than ever before, AI is also making it possible to reduce accidents by optimizing flows across intersections as well as improving safety during periods when roads are shut down due to construction or other events. Furthermore, AI’s ability to process and analyze vast amounts of data has allowed for effective mass transit, such as ride-sharing services. So how is AI revolutionizing road traffic management?

How is AI used in traffic management?

AI is used in road traffic management to help analyze real-time data from various means of transportation, including cars, buses and trains. The AI analyzes this information for patterns that could indicate safety risks. This information is then used to suggest ways to mitigate these risks and reduce the number of accidents that occur. Phoenix is implementing a new traffic management system which uses AI in order to coordinate lights. Phoenix has seen a 40% decrease in vehicle delay time through this system.

Phoenix Street Transportation Director Kini Knudson thinks AI will make traffic management more efficient: “We’re using technology that wasn’t available five or 10 years ago.”

Phoenix is one of many cities that are currently testing the use of AI in traffic management as part of larger initiative by Maricopa Association of Governments, which tests new technologies for viability before large-scale investments are made. Safety and the real world are paramount to this rollout process.

Traffic Lights – Traffic signal control system

Traffic lights are an important part of the transportation infrastructure. They help to keep traffic flowing and organized.

In the past, traffic lights were run by humans. They used timers and other tools to keep things running smoothly. However, that is no longer the case. Today, traffic lights are run by computers. This change was made in order to make things more efficient. It allows for better control over the timing of traffic lights.

In recent years, there has been a push to make traffic lights smarter. This is done with the goal of increasing efficiency for drivers.

One company that is leading this effort is called NoTraffic. It’s behind the new effort to make traffic lights smart. This company is trying to use artificial intelligence to improve traffic management.

Automatic distance recognition

Automatic distance recognition (ADR) is a technology that uses sensors to detect the distance between a car and an object in front of it. These sensors include lasers, radar and cameras.

The purpose of ADR is to maintain a safe distance between the car and the object in front, thus reducing the risk of accidents.

ADR systems are becoming increasingly common in modern cars.

Many different companies offer ADR systems, including Tesla, Volvo and Mercedes-Benz.

Smart Parking

AI can help predict parking situations. For example, if there is a concert or other major event in town, AI can help identify the areas that are most likely to be congested and recommend parking spots ahead of time. This would help drivers avoid traffic jams and save time.

Law Enforcement in Traffic using AI

AI is used in traffic management to enforce the law. ITMS provides a tool to automatically challan offenders as per law of the land, with supporting evidence data in terms of snapshots & videos. AI is also used for speed violation detection which alerts the user when there are multiple people riding on a bicycle or motorcycle with no helmet, this helps prevent accidents involving those two modes of transportation and other motorized means of transport. The system can also be integrated with CCTV and Traffic Control systems, which results in a holistic solution towards preventing the current traffic menace.

What is ITS? – Intelligent Traffic Management System

ITS is a computer vision applied field, which is focused on vehicle classification, traffic violation detection, and traffic flow analysis. ITS often helps reduce the amount of congestion by paying attention to factors such as the distance between two moving vehicles and pedestrians at crossroads.

ITS uses AI to help traffic move more smoothly by incorporating IoT and AI in order to improve mobility, reduce pollution and lower death rates.

What are the Benefits of using AI in traffic management?

Many road traffic processes can be significantly improved. Every driver who has to wait at a traffic light for minutes on end – even though there is no apparent reason for doing so – except that the traffic light system works according to a fixed pattern that is completely independent of the current traffic situation can relate to this. The use of artificial intelligence to keep traffic moving in response to the current situation has many advantages:

Traffic flowing AI
Flowing traffic – With the power of AI
  • Flowing traffic, with no traffic jams, is good for the environment. And this calls not so much for the use of hardware as for the further development of software, making it another relevant environmental aspect.
  • It enables the optimization of many business processes, such as deliveries, which is of great benefit to the economy.
  • Human error, by far the most frequent cause of accidents, can be largely eliminated by comprehensively managing the flow of traffic. Eliminating the human factor could drastically reduce the number of accidents.
  • It also presents attractive opportunities in the transport sector: the term Truck Platooning describes the concept of electronically linking several trucks driving in a convoy on the highway. Here, a human driver only sits in the leading vehicle. AI takes over the control of all the following trucks.

All these factors contribute to the optimization of the overall traffic system. Every road user benefits from this – even those who were previously only able to participate in road traffic to a limited extent without the aid of digital tools.

By identifying upcoming events and displaying them on an easy-to-use visual map, Eventflow helps transportation managers plan their routes more effectively. This can lead to increased ridership and service levels, as well as reduced manual searches.

Eventflow also has two APIs – one for developers, the other for non-developers who want data in an open format. This makes it easy for transportation managers to leverage existing systems to create new opportunities for ridership and service levels.

Quality Data – The Key to artificial intelligence in road traffic

Self-driving cars are going to rely on AI traffic management systems being implemented as part of the infrastructure. It’s important that these systems have access to high-quality data so they can function correctly and keep everyone safe on the roads. That’s why we’re committed to providing the best possible data for our customers.

The quality of the software designed for use in road traffic is influenced on the one hand by the programming of the algorithms, but also to a large extent by the quantity and quality of the training data. The more reliable and realistic datasets for machine learning are, the more potential there is for safe road traffic design.

It is obvious that AI in road traffic has to accept many setbacks, especially in the current stage of development. Accidents caused by faulty software have made the headlines again and again. However, from a realistic point of view, these individual incidents are only partially suitable for questioning autonomous driving in principle. A final statement on the contribution of autonomous driving to road safety and the reduction of accident figures calls for a reliable comparison that puts two figures in relation to each other:

  1. How many accidents are caused by faulty programming?
  2. How many accidents occur in the same situations due to human error?

Accidents that result from software errors are closely monitored by the public. In contrast, lack of human attention as a cause of accidents rarely makes it into the headlines. However, this does not necessarily reflect the everlasting superiority of human control.

AI in traffic management – A controversial support

The use of artificial intelligence (AI) in traffic management is a controversial topic. While some believe that it could help reduce congestion and improve fuel consumption, others are unsure of the benefits that AI can bring to this field.

Traffic congestion is often seen as a bane to city life. It can cause frustration for drivers, lead to increased emissions, and even increase the likelihood of road fatalities. However, it is not clear how much of an impact AI can have in reducing these factors.

There are many applications for which AI can be used in traffic management. For example, emergency vehicle preemption allows vehicles such as ambulances and fire trucks to bypass red lights or other obstacles when responding to an emergency. Transit signal priority gives buses priority at intersections so they do not get stuck in traffic, which improves overall travel times for passengers. And pedestrian safety systems use sensors embedded in the road surface to detect when someone is crossing the street so that the crossing signal will change more quickly.

While there are many potential benefits to using AI in traffic management, it remains a controversial topic due to concerns about its reliability and efficacy.

Challenges of using AI in traffic management

There are several challenges when it comes to using AI in traffic management.

  • Data acquisition and understanding the underlying challenge.
  • Data processing and feature extraction for predictive modeling.
  • Model deployment, monitoring, and updating.
  • Feedback analysis and learning from mistakes.
  • Dealing with uncertainty and noise in the data.
  • Integrating different types of data (e.g., video, image, GPS)
  • Scalability – can the system handle increased load as cities get larger?
  • Privacy concerns – how will personal information be used or shared?
  • Cost-effectiveness – can AI be used without making significant investments in new infrastructure?
  • Standardization – will there be a single platform that all municipalities use to manage traffic?

Cyber security issues


IT Security for AI Traffic
IT Security is of most importance for AI Traffic Systems

Cyber security is a very important issue that affects the data and operations of modern day technology. The reason why cyber security is so important for systems such as these, which are directly focused on managing road traffic, is that they are subject to potential attacks from hackers who may cause serious damage. These systems cannot function correctly if they’re not secure and there’s a chance that the data could be manipulated.

Cyber security issues for road traffic management systems are the potential vulnerability of computer-based components including GPS, mobile apps and websites to cyber attacks. This can lead to a loss in traffic flow and operational disruption.

Economic questions

Advantages of AI in traffic will save time and money for a city’s transportation department, as well as have less of an impact on the environment. Improving an individual’s ability to maximize their time can also improve efficiency. If individuals are able to efficiently manage their time, then they will be able to make more money.

An economic question is whether the system of autonomous cars will actually be cost-effective in the long term. There are some major concerns over how to deal with the cost of replacing human-driven cars with self-driving ones, as well as an issue that needs to be resolved before autonomous vehicles are permitted on public roads.

Ethical considerations – Will AI replace us in traffic management?

New technology has caused some social questions to be raised about employment, though. For instance, will people who have traditionally held jobs in the transportation industry now be out of work? Or will this just create new opportunities for those who are looking for work? For example, if a job can be done faster and more accurately by a machine, what happens to the people who used to do that job?

In some cases, machines may be able to do things better than humans can. For example, Nvidia has developed a machine learning algorithm which is able to read traffic signs faster and more accurately than humans. This could lead to jobs such as traffic signal maintenance workers being replaced by machines.

Is it fair for someone who has been working in a job for years to lose their livelihood because a machine can do it better?

Fair or not, artificial intelligence is not likely to replace humans in the near future due to its current limitations, but it could still increase efficiency of human labor by speeding up and automating tasks. For example, AI can help us process large amounts of data more quickly and efficiently than humans can. It can also help us make better decisions based on complex data sets. As such, it is likely to play an important role in many fields, including healthcare, finance, and manufacturing.

The Smart City – AI Traffic Systems in cities

Traffic Management in a Smart City

The term “smart city” has been around for a few years now, but what does it actually mean?

A Smart City is a city that makes efficient use of technology to provide services and benefits for the citizens. The most famous example would be Dubai, which has been built on cutting-edge technology that is able to provide the government and citizens with services such as public transport, traffic monitoring and waste management. Let’s take a look at a few characteristics and features of a smart city.

Adaptive traffic control system (ATCS)

An adaptive road traffic control system, or ATCS, is a type of traffic management system that uses artificial intelligence (AI) to optimize the flow of vehicles through an urban area. It can reduce waiting time at traffic lights by up to half and help city authorities better understand ground conditions and traffic trends.

ATCS is a key component of the growing smart traffic or intelligent traffic systems (ITS) market. According to MarketsandMarkets, The global ITS market is to reach USD 68.0 billion by 2026

Automated vehicles

Automated vehicles are becoming increasingly common on our roads. While many people think of self-driving cars when they hear the term ‘automated vehicle’, this is only one type of automated vehicle.

Delivery Drone
Automated delivery using a drone.

Other types of automated vehicles include:

  • Taxis
  • Buses
  • Delivery vans or drones
  • Trains
  • Commercial aircraft

Automated vehicles can offer a number of advantages over traditional, manned vehicles. For example:

  • They can help to reduce energy consumption caused by idling vehicles and help to reduce engine emissions.
  • They can automate parking processes, freeing up time for drivers to be more productive.
  • Automated systems are improving at differentiating between road users, which can improve safety.

However, there are also some disadvantages to using automated vehicles:

Humans are still required to make decisions that require long-term planning, though many tasks can be automated for immediate issues like accidents and traffic rerouting. For example, the Vivacity Smart City relies on humans and machines working together to alleviate the burden of heavy traffic in the city centre. Another disadvantage is that automated systems can be expensive to implement and maintain.

Intelligent parking planning

Imagine you are driving in to the city for a meeting. You know there is a lot of construction going on, so you leave extra time to find parking. As you get closer to your destination, you realize that finding parking is going to be even more challenging than you thought!

But what if there was an app that could predict parking situations up to 5 hours in advance? That’s where Eventflow comes in. They are a company that specializes in predictive analytics and event forecasting. Their application predicts everything from traffic congestion and blocked roads, to parking availability and rest periods for truck drivers. This information is then made available through an easy-to-use HTML5 visualization tool, which is available through an open API.

Reducing Traffic Congestions – Improving Road Traffic Flow

Artificial intelligence can reduce traffic congestion by routing cars around clogged areas, optimizing delivery routes and reducing the need for construction. Smart cameras at junctions can automatically identify different road users, such as pedestrians, cyclists, and cars. Traffic management systems should be adjusted according to the needs of road users, such as air quality or school traffic. For example, if there is an accident on a certain road, the system would need to reroute traffic accordingly.

However, humans are still required to make decisions that require long-term planning, like where new roads should be built. Although many tasks can be automated for immediate issues like accidents and traffic rerouting, humans are still necessary for the overall management of the city’s traffic flow.

Safety and Emergency Situations

Emergency situations are a cause of great concern for everyone. In such times, it is vital that the authorities are able to act quickly and efficiently to ensure the safety of all citizens. To this end, agencies are going to implement an Integrated Traffic Management System (ITMS). The ITMS will automatically regulate the signal light and caution motorists on diversions. The new system will play a vital role in facilitating a quick passage to emergency vehicles such as ambulances and fire tenders. The ITMS will also caution motorists on diversions to be taken in case of any congestion ahead.

AI and Public Transportation
AI has its uses for Public Transportation

Transit Planning – Intelligent Transportation Systems

Using AI to plan transit can reduce travel times and traffic congestion while increasing the effectiveness of buses, trains and ferries. AI helps planners decide which type of transportation is best for a certain area and what the most efficient route would be. In order to improve public transportation, artificial intelligence can be used to optimize the routing of buses and trains so that they are more efficient. AI also helps create better schedules for transit authority employees who are managing the routes.

Urban Planning

Urban planning is the process of designing and managing the growth of urban areas. It involves the creation of plans for the development and use of land, transportation systems, public facilities, and services such as water supply, waste management, and energy distribution.

Urban Traffic
Finding the right balance in city planning is important.

The main objective of urban planning is to create a livable environment in which people can work and live. This requires balancing the needs of different groups such as residents, businesses, commuters, and tourists.

In order to plan effectively, cities need accurate data on population size, demographics, employment trends, economic conditions etc. Cities also need to understand how people move around within them.

This is where technologies like AI and machine learning come in. They can help cities collect data more efficiently and analyze it faster. This helps planners make better decisions about how to allocate resources.
