The future Westerschelde tunnel will consist of two separate tubes of 6.6 km in length, with each two different traffic lanes. Due to financial constraints a separate evacuation tube for pedestrians will not be built. In order to allow evacuation of road users to the other tunnel tube, transverse connections will be built between the two tubes. Since the cross-section of a tube does not allow any room for an emergency lane or a pedestrian lane along the side of the road, car drivers escaping on foot from the unsafe tube, will enter the road in the safe tunnel tube. Conflicts between moving traffic and escaping car drivers can result in other unsafe situation. It is important to minimise this unsafety. This report discusses recommendations for this problem. (A)
