# Blue Light Maps > Operational mapping for emergency services. Blue-light routing, real-time overlays, and trusted data layers built for police, fire, and ambulance crews — on the devices they already carry. Blue Light Maps Limited is a UK company building emergency-vehicle mapping and navigation. The product is used by police, fire & rescue, and ambulance services, plus individual blue-light responders. It runs on iOS and Android, integrates with CarPlay and Android Auto, and supports MDM deployment for fleets via Intune and equivalent. The core differentiator is that the routing engine accounts for emergency-vehicle exemptions (bus lanes, contraflow, restricted turns, pedestrianised zones) and vehicle-specific constraints (appliance dimensions, weight, speed humps) — finding faster routes to scene that consumer navigation can't surface. Operational overlays (hydrants, RVPs, cordons, MISPER locations, ANPR, custom force/service data) sync to every device in real time. ## Capabilities - [Blue Light Routing](https://bluelightmaps.com/responder-app/blue-light-routing): Routing engine that respects emergency-vehicle exemptions and vehicle dimensions. - [Blue Light Alert](https://bluelightmaps.com/responder-app/blue-light-alert): Broadcasts an approaching-emergency-vehicle warning into Waze along the active route, giving drivers ahead 4× more reaction time than lights and sirens alone. - [Custom data layers](https://bluelightmaps.com/responder-app/custom-layers): Service-specific overlays — hydrants, hazmat, vulnerable persons, intelligence pins — drawn from the service's own records. - [Shared overlays](https://bluelightmaps.com/responder-app/shared-overlays): Real-time sync of cordons, RVPs, sector boundaries, and unit positions across every device on an incident. Includes live location sharing (callsigned unit positions, shared to invite-only groups) and shared ETAs — crews responding to the same incident see each other's status and live arrival times, organisation-wide or per sharing group. - [Multi-platform](https://bluelightmaps.com/responder-app/multi-platform): iOS, Android, CarPlay, Android Auto, web. - [Trusted data](https://bluelightmaps.com/responder-app/trusted-data): Built on Ordnance Survey addressing, what3words, OpenStreetMap, Street View, Waze, CAD-system integrations. ## Use cases - [Fire & Rescue](https://bluelightmaps.com/use-cases/fire): Hydrant overlays, RVPs, weight/dimension-aware routing for appliances. - [Police](https://bluelightmaps.com/use-cases/police): Pursuit-aware shared overlays, Ordnance Survey addressing on complex estates, priority-area layers. - [Ambulance](https://bluelightmaps.com/use-cases/ambulance): Smooth-route preferences (avoiding speed humps), accurate A&E ETAs. ## Evidence - [Case study: Dorset & Wiltshire Fire and Rescue Service](https://bluelightmaps.com/case-studies/dorset-wiltshire): "It has made a positive difference in reaching incidents more quickly and effectively." — Daniel Grew. - [Blog](https://bluelightmaps.com/blog): Field-tested write-ups on routing, response-time data, integrations. ## For IT and developers - [Documentation](https://docs.bluelightmaps.com): Responder-facing guides (including [location sharing](https://docs.bluelightmaps.com/responders/location-sharing) and [shared ETAs](https://docs.bluelightmaps.com/responders/shared-etas)), IT/MDM deployment, deep-link API. - [Enterprise deployment (Intune)](https://docs.bluelightmaps.com/it-teams/enterprise-deployment-intune): Managed-device rollout. - [MDM vehicle profiles](https://docs.bluelightmaps.com/it-teams/mdm-vehicle-profiles): Pre-configured vehicle profiles for fleet deployment. ## About - [About Blue Light Maps](https://bluelightmaps.com/about): Company background. - [Contact](https://bluelightmaps.com/contact): Demo requests, trial enquiries, support. - [Privacy](https://bluelightmaps.com/privacy) - [Terms](https://bluelightmaps.com/terms)
