The crash safety of vehicle has been investigated for about 6 decades. The passive safety for the driver has been improved extremely. However, the safety consideration for the walker is not enough yet. Near the pedestrian crossing at the crossroads, there may be the concrete block, which is on the side of the intersection point of roads, on the center lane. This block protects the walker against the vehicle crash and is very strong. On the other hand, its heavy weight causes the high costs for the transport and setup, and its brittleness causes the anxiety about the secondary accident due to the broken pieces. Therefore, the new structure that consists of the urethane resin and the steel parts was newly proposed. In this study, the crash analysis of vehicle against the urethane barrier model was conducted with the experimentally obtained dynamic material properties for the urethane resin. The improvement of performance was evaluated by comparing with the result of the crash analysis against the corresponding concrete block model.
