A pedestrian access terminal is disclosed having a pair of spaced apart terminal blocks that allow pedestrian passage along a roadway. The bottom portions of the terminal blocks are set beneath the surface. A portal extends vertically through each terminal block. Foundation posts are vertically positioned below the surface and extend upward into each portal. Fasteners secure a traffic barrier to each terminal block and foundation post. A tensioning member extends between the foundation posts to increase resistance to lateral movement. Soil plates may be attached to the foundation posts to further resist lateral movement.

A central road safety barrier includes modules mutually couplable by means of a bolt which engages holes made in protrusions extending in a longitudinal direction at the ends of the modules. Walls adjacent to the protrusions improve the transfer between the modules of an impact of an errant vehicle on the barrier and improve response to an impact. The safety barrier provides an emergency openable passage. A module may include a wall solidly constrained to an upright and adjacent to the protrusions of the module on a first side of the barrier. An openable passage module has a further wall solidly constrained to a further upright and adjacent to the protrusions of the openable passage module on a second side of the barrier.

A terminal element (100) of a traffic barrier device (1), having a longitudinal axis, comprising a guide element (10) and an impact element (20). The impact element (20) is pivotally mounted on the guide element (10) about a vertical axis (A) so as to be rotatable or pivotable about a vertical axis. The impact element has a connecting side, for connection to an adjacent traffic barrier device, and an impact side, for damping or repelling an impact. The vertical axis is arranged between the connecting side and the impact side.

A rotational deck which is used for an emergency vehicle return apparatus in a section of a median strip of a road, includes a pair of angle decks configured to be folded up to serve as the median strip in a normal state, and be unfolded down by hydraulic cylinders toward a surface of the road to serve as a vehicle pass in an event of emergency, and a front block part coupled, by a link unit, to a lower portion of each angle deck. The front block part includes a front block having a shape to reduce a shock from a collision, one or more front block frames configured to provide rigidity by supporting a rear surface of the front block, and a bottom frame configured to support the front block and a lower portion of the front block frame.
