Download the whitepaper Governments worldwide are increasingly adopting AI to enhance public safety. From predictive policing in the U.S. to real-time traffic risk detection in the UK, these AI in the public sector examples showcase the transformative power of emerging technology.
Today, AI models can harness an immense variety of data for public safety interventions, from CCTV cameras and social media activity to sensory data from connected vehicles and smart devices.
A McKinsey report found that smart technologies such as AI could help cities reduce crime by 30 to 40% and emergency service response times by 20 to 35%. In 2019, according to the AI Global Surveillance Index, 56 out of 176 countries were already using AI for surveillance.
However, effectively utilising this data requires a strategic (and ethical) approach. The combination of AI technologies, such as computer vision and machine learning (ML), with behavior design principles is essential to unlocking the full potential of these solutions.
We have 4 public safety use cases to demonstrate how AI technology in the public sector can bring long-lasting results when implemented in the above way.
The UK has one of the highest concentrations of CCTV cameras worldwide. While these publicly managed systems primarily aim to deter crime, the extensive data they gather can also be used to enhance public safety in other ways, such as managing and optimising crowd movements in busy areas.
Singapore’s Smart Nation initiative leverages data from CCTV networks to identify how people use its services from bike paths to outdoor exercise equipment and to deliver real-time, context-sensitive nudges to residents commuting through the city. Digital displays in public spaces provide live crowd-density information, subtly guiding people away from overcrowded areas.
Unlike CCTV-based solutions that track individual behaviors, which raise significant privacy concerns, this approach focuses solely on crowd behavior and flow, similar to systems used in airports. The initiative has also helped emergency services respond more quickly by using data to find the best routes through the city. The displays inform large crowds when emergency vehicles are approaching and request specific routes to clear a path.
With the rise of connected vehicles and smart mobility, modern transportation has become a vast network of real-time, geo-localised data. Vehicles, from passenger cars to e-scooters, act as "sensors on wheels," constantly generating valuable information on road conditions, traffic, and driving behavior.
Coupled with the enormous amount of historical data on accidents, weather, and lighting conditions, this presents a goldmine for machine learning algorithms to identify risky hotspots and dangerous traffic zones.
This enables authorities, municipalities, and urban mobility professionals to take proactive measures by changing the hazardous road conditions that contribute to accidents or by providing preventative warnings to drivers and pedestrians about potential dangers to help them take actions to avoid them.
Zurich and other cities use Vianova’s machine learning solution to improve road safety by identifying high-risk zones.
Their "Multimodal Road Safety" system—multimodal meaning the integration of vision, hearing, and speech— collects real-time data from connected vehicles, such as speed, location, and braking, to analyse traffic flow and road conditions. By combining this with historical crash data, Vianova’s algorithms detect hazardous areas and assign risk scores to roads and intersections based on factors like over-speeding and sudden braking.
This allows authorities to implement targeted safety measures, such as redesigning intersections, installing speed cameras, or adjusting infrastructure to reduce accident risks.
Predictive policing was a feature of the 2002 movie Minority Report, where a police division arrests criminals prior to them committing the crime. Today, many cities are experimenting with AI-driven crime prevention solutions that aim to proactively guide people away from potential misconduct.
It’s well documented that police, or even police-like presence (fake CCTV cameras or cardboard cutouts of police officers) can reduce criminal activity.
Predictive policing AI systems have also attracted attention for their potential to forecast and help prevent crimes. Such tools employ data analytics, machine learning, and pattern recognition to analyse historical crime data and other relevant factors, identifying crime hotspots and forecasting when and where crimes are most likely to occur. This proactive approach aims to enhance public safety by enabling law enforcement agencies to allocate resources more effectively and intervene before incidents happen.
A common criticism of predictive policing is its susceptibility to data bias. Relying on historical crime data risks reinforcing existing biases, as areas with a history of high policing are more likely to be flagged, potentially leading to cycles of over-policing. This, combined with a low level of transparency in how the algorithms work, has sparked debates about their fairness and ethics. To address these concerns, regular audits of the data and algorithms are essential to spot and reduce any biases.
In the UK, five people die every day on the road and 58% of deaths had speed as a road safety factor. Alongside major campaigns to try to intervene, how can AI help provide some introspection into drivers’ habits?
Cambridge Mobile Telematics’s DriveWell Fusion platform tracks driver behavior by collecting data from phone sensors, including GPS, accelerometers, and gyroscopes, and uses machine learning algorithms to analyse driving patterns like harsh acceleration, sudden braking, sharp turns, and speeding.
The AI platform also looks at the phone's movement patterns to determine whether the phone holder is the driver or a passenger in the car, helping to prevent phone usage while driving. Drivers receive real-time feedback in the form of push notifications and weekly reports, coaching them to improve their habits.
Another promising area for improving road safety is AI DashCam systems, which can monitor potential risks on the road, providing real-time alerts for hazardous conditions such as distracted driving or fatigue, and track drivers with inward-facing cameras, helping drivers remain focused and attentive.
Going beyond reactive alerts, this AI technology could identify recurring issues like speeding or tailgating and offer personalised coaching. Facial or voice analysis would detect emotional states like stress or anger, allowing the system to intervene before risky behavior escalates and provide calming prompts or advise rest breaks.
