Round and round the spike speed humps to come together with the top of the left circle deceleration spike size of the slot, the spike fixed in a circular deceleration zone at the top of the slot. Increase their nighttime reflective brightness. Disk-like design can be an effective force decomposition deceleration zone, increasing its compression capabilities. Installed separately, had plenty of space in the middle to facilitate cyclists, reduce vehicle bumpy feeling.
