What is the grid-like figure next to the parking space drawing?

Parking spaces marked with yellow grid lines are barrier-free parking spaces, which are special parking spaces for motor vehicles driven or taken by physically disabled people, and the yellow lines play a role in prompting.

There is a parking space with a yellow grid line. On the parking space, there is a design of wheelchair for the disabled. According to the Code for Barrier-free Design, there is a "wheelchair for the disabled" pattern in the barrier-free parking space.

Barrier-free parking spaces, with clear and eye-catching white "barrier-free parking spaces" signs, have played a good role in indicating and guiding, and wheelchair access has been specially reserved for the convenience of disabled people.

Setting requirements:

1. No matter whether it is located on the ground or underground, the parking space with convenient access and the nearest route to the entrance and exit should be arranged as barrier-free motor vehicle parking spaces, and barrier-free motor vehicle parking spaces should be set next to the entrance and exit if possible.

2. The ground of barrier-free motor vehicle parking spaces should be smooth, non-slip and free of stagnant water, and the ground slope should not be greater than 1:50.

3. Wheelchair access with a width exceeding 1. 20m should be reserved at one side of the parking space or between the parking space and the adjacent parking space.

4. Parking lines, wheelchair access lines and barrier-free signs should be painted on the ground of barrier-free motor vehicle parking spaces.
