Incident process steps 4–6: Route navigation from closest responder to incident site using real-time traffic and weather data (own figure). The web application shows the indicators: Location of incident (longitude, latitude); buffer in metres; the number of available responders; and the location of the closest responder (responder longitude and latitude, responder ID, responder name and distance to the incident site). The map output visualises the location of the incident on the Tyne Bridge with a red marker and a red circular buffer area around the incident location. The black marker with the white letter "R" near the river indicates the closest responder to the incident site. The blue-marked road indicates the route in the network leading from the location of the responder to the incident site. The road network shows the traffic flow using the color ramp from green (fast) to red (slow). The pop-up windows show the current weather and road network conditions. KW created the map output using the Microsoft Azure Maps Web Software Development Kit and TomTom ( ^© 2022) base map data (a subscription key to use the data can be obtained after registering on the Azure Maps platform for Geospatial Mapping APIs under https://azure.microsoft.com/en-us/services/azure-maps/#azuremaps-overview). The code for the web application was developed in JavaScript, CSS and HTML in the Microsoft Visual Studio Code integrated development environment (version 1.70.2) and Node.js (version 16.13.2) on a Windows NT 64-bit operating system (×64-based processor)^40.
