guiding cyclists through the dark dutmala tunnel in eindhoven, the netherlands, ‘transit mantra’ is an interactive sound and light sculpture designed by amsterdam-based designers knol ontwerp. opened in august 2013, the symbiotic piece provides an improved sense of safety for people crossing through the tunnel. influenced by the history of eindhoven, a city fused by a cluster of former villages – its decentralized character is still apparent today when one passes through. based on the notion of ‘being in transit’, the swarm-like installation seeks to enhance this experience, offering a pleasant moment of reflection. when people move through the tunnel, the overhead sculpture reacts to the human movement. cleverly, it responds differently to an individual walking through versus a group of people on a bike – the velocity and number of passengers influences the behavior of the installation, leading to an ever-changing pattern of light and sound.

informed by the energy of the passengers, the tunnel is turned into a collective instrument. ‘transit media’ is a successful example of functional, innovative technology but with a strong aesthetic component. the installation reassures passengers entering the tunnel, as the light trail of the last person remains visible, glowing for a while afterwards.


‘in bicycle tunnels people always experience a certain unsafe feeling. if they see that others were just before them, this feeling decreases.’ says mary-ann schreurs the alderman of innovation, design, culture and public space.
