The width of an ordinary driving ramp should be smaller than the width of the connected doorway

The width of an ordinary driving ramp should be greater than the width of the connected door opening, generally at least ≥500mm on each side.

: According to their different uses, ramps can be divided into two categories: driving ramps and wheelchair ramps. Driving ramps can be divided into two types: ordinary driving ramps and return ramps. Ordinary driving ramps are arranged at hotel entrances where vehicles enter and exit, such as garages, warehouses, etc. The return ramp and steps are combined and arranged at the entrance of some large hotel designs, such as hotels, hotels, etc.

When steps cannot be constructed due to use or other reasons, ramps can be used to accommodate changes in height. Public green spaces and public buildings usually require barrier-free access, and ramps are an essential factor. Ramps are an important method of converting pedestrians into heights at ground level.

Ramps are an important method for pedestrians to achieve height conversion on the ground. Compared with steps, ramps have an important advantage, that is, the ramp surface allows almost all kinds of pedestrians to freely walk through the landscape. Ramps are an essential factor in the design of "barrier-free" areas. On the slope of the ramp, the ground can connect a series of spaces into a whole without any trace of interruption. It should be noted, however, that some people find walking on inclines more difficult than walking on stairs.

They prefer stairs. An obvious shortcoming of the slope is that in order to obtain a stable and suitable slope, a relatively long horizontal distance is needed to maintain the slope height change. In areas where space is limited, the slopes have to be designed in a sinuous shape in order to achieve the required distance and slope. Another shortcoming of the slope is that when the ground is wet and the slope is not textured or paved with non-slip materials, pedestrians walking on it will be in danger of slipping and falling at any time.

From a visual point of view, because the slope is relatively long, it always gives people an unpleasant and uncoordinated feeling. If the ramp surface is not consciously and rationally designed, it will always look like it was added after the fact, which is extremely inconsistent.
