Thermal imaging & vision systems
Locating and reacting to incidents in reaL-time
We rely on the speed and assurance of essential services to assist us when road accidents occur. To react in real-time, they need smarter tools to minimise any disruption which adds time to their journey and inhibits them from reaching people in need. Typically, it is traditional video surveillance operations which are used in this instance and are useful for investigations, yet these lack the tools and coverage that could change the outcome of an occurring event in real-time. An example of authorities utilising this
Detection of a pedestrian (thermal camera) in Brynglas tunnels in South Wales
sensors for detection is that no extensive civil engineering is required. City technicians can install smart sensors and set it up without the cost of commissioning outside companies. The city of Darmstadt is using various types
of video sensors for vehicle, pedestrian and bike detection, all of which are used to control traffic flows in a more intelligent way.
a connected future for cities
Cloud technology can be utilised to ensure high-level communication between entities, and ensure the smooth running of a cities.
This enables a cohesive data collection for AI analysis, ensuring inter-device connectivity across different intersections in a city. The scalability and dynamic offering of cloud platforms allow for tailored solutions to seamlessly address specific problems across city-level operations, management platforms and associated interfaces. By combining this with smart thermal, cities have the tools in place to monitor and identify traffic flow, detect incidents in real-time and inform travelers of potential disruption. Through synchronising to a central node of
communication, the control centre allows for the retrieval of information from a unified access point. By using global displays and AI driven-data processing faster and more cohesive responses are enabled to reach service points across the city within a short period of time. As well as increasing first responder’s ability to react, the technology eases the flow and safety of traffic for the everyday traveller.
technology can be seen in Wales where authorities have utilised FLIR thermal imaging sensors on a notoriously dangerous tunnel. With 80,000 vehicles passing through on peak days, incident detection technology is important for the safety of the tunnel/road users. By combining smart visual and thermal cameras, officials are notified of potential hazards or incidents occurring within the tunnel, helping decrease the number of incidents. Plus, it is not only the immediate benefits we
can see from safety features. The vast amount of data collected from daily monitoring can then be analysed and used by city authorities to make these roads safer. This use of variable speed limits has also enabled urban planners to make smarter, safer transport decisions, slowing traffic down when an accident has occurred and minimising stand-still traffic. Initiatives such as these empower authorities
to adapt safety measures to meet their own city’s needs. From targeting slow commutes and dangerous crossings in Darmstadt to reducing collisions in a busy tunnel in Wales - recognising and building intelligent solutions to unique issues has never been more of a reality. Technology is enabling cities and its citizens to keep moving while allowing authorities are able to prioritise the safety of communities in their vision of a future smart city.
