Keeping information organized is neccessary for learnability and efficiency. It is especially important when the information is related to schedules or rules. The examples at the left both tried to represent parking schedule. The first schedule sign is terribly designed because it only use text to represent its information. Users have to consider multiple conditions simultaneouly, and most importantly it distracts user's attention.

On the other hand, the second schedule sign reorganized the text infromation and represented it as a graph. With graphical representation, you can get benefits from color, alignment, visual contrasts, etc. These helps to improve your learnability and efficiency because users can understand the overall picture more clearly and they do not require to process the imformation in their brain; users do not have to remember each details to organize. So, whenever possible, try to represent information with visual cues rather than text.
