Customized and personalized indoor guidance and localization of crowds or individuals, inside a building, for either evacuation or sheltering (during emergency situation) or the best routes to reach spots of interest (Indoor locationbased services, for example, shop with special offers in commercial malls) is of utmost importance for safety issues or customer satisfaction. Most of the existing evacuation systems are mainly based on warning mechanisms (sound, visual, ...), and pre-established routes which do not consider the presence of obstacles or spots of interest popping out, dynamically, in real-time. The existing solutions are not always able to provide simple and effective evacuation/guidance instructions. Thanks to progress in telecommunication technologies, connected things and BIM (Building
Information Model), the GuidEvac solutions provide people or evacuation agents, in indoor context inside buildings, with the best evacuation/guidance instructions in real time.
