Supermarkets
A plan with a purpose
A modern supermarket can be divided into three main areas: the entrance-exit area, the space along the four walls, and a large central area. The central area consists of long rows of two-sided shelves with aisles between them. The supermarket is designed so that customers can see and choose items easily, and walk easily and quickly around the entire supermarket.
Entrance
A market has one or two entrances. The entrances guide customers directly to the shopping carts and shopping baskets. In some supermarkets it is not possible to leave through the entrance because the automatic doors open only one way, or there is a turnstile inside the market that moves in one direction only. Customers are "trapped" inside the market.
