This is a medium-sized block that can be used as a buffer material for road construction work zones, as well as for lane separation and lane narrowing at toll booths.
It is possible to restore the direction of travel during contact collisions. It has the effect of alleviating congestion and facilitating smooth vehicle flow at places like highway toll booths and road construction sites. When ETC lanes are parallel to existing lanes, they are installed as guiding lanes. Additionally, changes to the guiding lanes in response to fluctuations in the number of users can be made promptly. It also serves as a boundary for vehicle entry prohibition areas, acting as a divider for parks, walkways, and shopping districts.
