Parking lot layout requires adherence to precise standards that ensure smooth traffic flow and optimal space utilization. Here are the most important standards and basic dimensions used in layout: 1. Standard Parking Dimensions Perpendicular Parking (90 degrees): The standard size is usually 5 meters long × 2.5 meters wide. Parallel Parking (along the curb): The parking space should be at least 6.5 meters long and 2.5 meters wide for easy maneuvering. Variable Width: A width of 2.3 meters may suffice if the parking space is open on both sides, while it increases to 2.5 meters if it is next to a wall to ensure doors can be opened. +2 2. Layout of Aisles and Entrances Aisle Width: It is preferable that the width of a one-way traffic lane is not less than 6 meters to allow for safe maneuvering. Parking Angles: 90-degree angle: Provides the largest number of parking spaces in a rectangular area and is suitable for two-way aisles. Angled (45 or 60 degree) angles: Facilitate the entry and exit process and are suitable for one-way aisles.
