EZY-CRD-GO is an interdisciplinary and international project lead by Technische Universität Berlin, Chair id Sustainable Urban Planning and Design, CyPhyLab – laboratory for cyber-physivcal systems in architecture and urban design. It is an EIT Digital Innovation Activity is the  focus area Digital Cities. The Innovation Activity is funded by EIT Digital (European Institute of Innovation and Technology) as part of Horizon 2020, the largest EU Research and Innovation programm.

Innovation Activity​


EZY-CRD-GO is an EIT Digital Innovation Activity in the Focus Area Digital Cities. Based on a consortial organisational structure the following partners are pooling their respective academic, research and industrial expertise: Technical University of Berlin (TUB), Telecom Italia S.p.A. (TIM), Experientia Srl (EXP),  Fraunhofer Heinrich-Hertz Institute (HHI) and the Polytechnic University of Milan (Polimi). 


The EZY-CRD-GO solution offers crowd guidance (i.e., per light-as-a-service) and exit strategies for stakeholders (e.g., security guards) from event management and facility operations. An IoT based exit and way-finding platform guides large crowds safely out of mass events (e.g., football, festivals). Intelligent lights are used for dynamic real-time feedback of the crowd’s behaviour. 


We work on the success of EZY-CRD-GO for event managers, planners and operators to increase their visitors’ satisfaction, orientation, and comfort during an event. For visitors, EZY-CRD-GO supports venue navigation. For event operators, it supports an understanding of crowd movement behavior. The data analysis platform enhances planning for safety in venues. The dashboard helps to manage event entry and exit gates with relevant real-time information. The goal is to create a safer environment for visitors.

Method & Technology

IoT Devices
A sensing component enables crowd analysis. It includes GPS, a RaspberryPi4 to control cameras for crowd density analysis, and a WiFi Module to streams anonymized data to our cloud platform.

A lighting component delivers information transmitted by the sensor stack and cloud. The lights inform the event visitors about gate status, whether occupied or accessible.

A graphic user interface component visualizes the venue situation in real-time in a dashboard for event operators. It shows metrics on crowd density and recommends safe choices.
