Hotel ramp reconstruction standard

It's that simple. Just put the access card at the lower end of the ramp.

Before the vehicle leaves the library, swipe the card first, and then climb the hill to leave the library.

If there is a problem moving to the bottom, you can only move it out at the exit of the ramp and let the vehicle swipe the card after climbing. Generally speaking, the card swiper should be about 5 meters away from the upper level of the ramp. For safety reasons, it is better to be outside 10 meter.
