Design Vehicle is a critical concept in parking facility design. When designing a parking facility, parking designers initiate the process by selecting a theoretical “design vehicle.“ The dimensions of this vehicle then guide the determination of suitable parking space and aisle sizes, forming the basis of the overall facility layout.
Key Considerations
- Selection of Design Vehicle: Rather than relying on the dimensions of an average-sized vehicle or the largest one available, the recommended approach by the Parking Consultants Council (PCC) is to consider the vehicle size that represents the 85th percentile of cars on the road today. This means the design vehicle’s dimensions are assumed to be standard for all vehicles in the parking design.
- Dimension Standards: By using the 85th percentile vehicle, designers ensure that 84% of the cars using the facility will be smaller than the design vehicle, offering most drivers an easier and more comfortable maneuvering experience. However, it also implies that about 14% of drivers, with vehicles larger than the design vehicle, will encounter more challenging navigation within the space.
Application in Parking Facility Design
- Parking Space and Aisle Sizes: The dimensions of the design vehicle directly influence the size of parking spaces and the width of aisles. This ensures that the majority of vehicles can park and maneuver comfortably within the facility.
- Layout Optimization: Using a standardized design vehicle helps in optimizing the overall layout of the parking facility. It allows for efficient use of space while maintaining ease of access and maneuverability for most users.
- Future-Proofing: Considering trends in vehicle sizes, including the increasing popularity of larger vehicles like SUVs and CUVs, helps in future-proofing the design. This ensures that the facility remains functional and user-friendly as vehicle preferences evolve. Additional
Considerations
- Safety and Accessibility: The design vehicle concept also plays a crucial role in ensuring safety and accessibility within the parking facility. By standardizing dimensions, designers can create clear and navigable pathways, reducing the risk of accidents and ensuring that emergency vehicles can access the facility if needed.
- Environmental Impact: Efficiently designed parking spaces that accommodate the majority of vehicles can also contribute to reducing the environmental impact. Properly sized spaces can minimize the amount of land used for parking, allowing for more green spaces or other sustainable features within the development.
- Economic Efficiency: By optimizing the layout based on the design vehicle, parking facilities can achieve economic efficiency. This includes reducing construction costs by avoiding overbuilding and ensuring that the facility can accommodate a high volume of vehicles without requiring excessive space.
- User Experience: A well-designed parking facility that considers the design vehicle can significantly enhance the user experience. Drivers will find it easier to park and navigate the facility, leading to higher satisfaction and potentially increased usage of the parking facility.
Conclusion
. The concept of a Design Vehicle is fundamental in parking facility design. By selecting a vehicle that represents the 85th percentile of cars on the road, designers can create parking spaces and aisles that accommodate the majority of vehicles, ensuring ease of use and efficient space utilization. This approach balances the needs of most drivers while acknowledging that a small percentage of larger vehicles may face more challenging navigation within the facility. Additionally, considering safety, accessibility, environmental impact, economic efficiency, and user experience further enhances the overall effectiveness and appeal of the parking facility.
