The State of Road Safety in 2026

According to research on intelligent transportation systems, the integration of IoT-enabled sensors and AI-driven models has significantly improved traffic flow prediction accuracy. However, critical challenges remain, including data integration, security, and scalability.

Urban bus rapid transit systems often face significant pedestrian safety challenges due to high passenger volumes and complex infrastructure layouts. These issues are compounded in rural areas like the A170, where lighting, signage, and road conditions may differ from urban environments.

What Smart Mobility Can Offer

Smart mobility solutions are transforming how cities approach transportation safety. From AI-powered traffic management to connected vehicle technology, the tools exist to make our roads safer—but implementation varies widely.

Key Technological Pillars of Smart Mobility Systems

1. IoT and Real-Time Data Collection

The Internet of Things (IoT) forms the backbone of modern smart mobility systems. IoT-enabled sensors collect real-time data on traffic flow, road conditions, and vehicle movements. This data feeds into intelligent transportation systems that can predict congestion, identify high-risk areas, and alert drivers to potential hazards.

For example, studies have shown that IoT-enabled sensors and AI-driven models significantly improve traffic flow prediction accuracy. Cities implementing these systems have reported measurable improvements in safety and efficiency.

2. GPS and Vehicle Tracking

GPS technology has revolutionised how we navigate and manage transportation networks. Real-time vehicle tracking allows traffic management centres to monitor traffic patterns, reroute vehicles during emergencies, and provide accurate arrival times to passengers.

In the context of the Ava Gillies car accident, GPS data could potentially help investigators reconstruct the sequence of events leading up to the collision. Dashcam footage, another form of vehicle-based data collection, has already been highlighted by police as a valuable tool for their investigation.

3. Smart Locks and Access Management

While primarily associated with building security, smart lock technology has applications in urban mobility as well. IoT-enabled smart locks can be used to manage parking spaces, prevent unauthorised parking, and reduce traffic congestion caused by illegally parked vehicles.

Some cities have deployed NB-IoT powered smart locks that can be raised or lowered remotely to control access to parking spaces. This technology helps reduce the time drivers spend searching for parking—a major contributor to urban congestion.

4. Vehicle-to-Everything (V2X) Communication

V2X technology enables vehicles to communicate with each other and with infrastructure. This includes vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication.

Researchers have proposed traffic accident prediction schemes based on V2X, which predict upcoming collisions and issue timely warnings by sharing data from surrounding vehicles and Road Side Units. In theory, such systems could prevent accidents like the one that claimed Ava Gillies’ life by alerting drivers to potential collisions before they occur.

5. AI-Powered Traffic Management

Artificial intelligence is increasingly being deployed to manage urban traffic. Cities like Lahore have deployed AI-powered drones to monitor traffic congestion in real time. Predictive algorithms analyse traffic disruptions, identify bottlenecks, and suggest data-driven solutions.

These systems can also be used to identify high-risk accident locations and implement targeted safety measures.

Smart Mobility in Action: Case Studies from Around the World
