Trends in Security Information
The HSD Trendmonitor is designed to provide access to relevant content on various subjects in the safety and security domain, to identify relevant developments and to connect knowledge and organisations. The safety and security domain encompasses a vast number of subjects. Four relevant taxonomies (type of threat or opportunity, victim, source of threat and domain of application) have been constructed in order to visualize all of these subjects. The taxonomies and related category descriptions have been carefully composed according to other taxonomies, European and international standards and our own expertise.
In order to identify safety and security related trends, relevant reports and HSD news articles are continuously scanned, analysed and classified by hand according to the four taxonomies. This results in a wide array of observations, which we call ‘Trend Snippets’. Multiple Trend Snippets combined can provide insights into safety and security trends. The size of the circles shows the relative weight of the topic, the filters can be used to further select the most relevant content for you.

Three reasons to monitor social media for traffic management
much information as possible.
There are many challenges in managing mobility and traffic. Incidents, roadblocks, planned events (e.g. concerts) and busy days are only examples of what can affect the traffic flow in a large city. To increase road safety, it is important to know what is happening, how an incident develops and how road users experience the situation. In short, you need as much information as possible.
The municipality of The Hague decided to take action and look for ways to best assist their traffic controllers. Despite their technology and intelligence tools (such as CCTV and sensors), they were still missing one source of information -
social media data. Now, for more than six years, the municipality is actively using PublicSonar's social media monitoring solution for their traffic management.
1. Early detection
When there is an incident, road traffic controllers are not always immediately informed by the road authority or the police.
Social media can therefore be a great first source of information. Helping you to respond quickly.
2. Situational picture
Messages and images on social media serve as background information and can provide additional insights. “It is particularly useful at times when we don't have camera footage. It gives us a better situational picture, ” says a traffic controller.
3. Additional information
Sometimes it is not always clear what has happened at certain places in the city or why a certain road section has been closed off. For instance, a traffic controller says that it is useful to consult PublicSonar to collect additional information afterwards.
