How to Optimize Your Parking Lot Design for Maximum Efficiency 

parking lot design

“I hate this parking lot!” I say it audibly every time we drive into the parking lot of the grocery store that’s nearest our home. It’s always hectic and comes with confusing interactions with other drivers. It’s not because drivers are trying to avoid potholes. Rather, it’s the poor parking lot design that makes drivers act weird: people unfamiliar with the parking lot are very hesitant and confused.

That’s one thing, but because this is a well-trafficked lot with EV chargers, lots of businesses (including a pharmacy and a UPS store), and a gas station, there are regulars. They have driven the meandering designated route through the parking lot a hundred times to go get gas on the way to work or drop off a package at UPS. They are overly familiar with the up/down aisles, random speed bumps, and many intersections. Not to mention they are also annoyed by the hesitant newcomers. You can’t drive across the parking lot to the gas station without honks, anxiety, and misplaced aggression.  

Not only does the design of your parking lot create a first and lasting impression for customers, but it also affects the efficiency of movement throughout the space. In this article, we will discuss some critical aspects of parking lot design and how to maintain your asphalt surface to ensure optimal performance. 

Evaluate Your Parking Lot Layout 

For business owners or property managers that oversee asphalt parking lots, it’s important to clearly understand your parking lot’s purpose, its capacity, and how it currently handles the parking demand. Then, depending on the parking lot’s primary purpose, you will want to optimize your parking lot design to ensure that it can accommodate the needs of those who frequently use it. 

Many parking lots are not designed to accommodate the number of vehicles that use the space on a daily basis, which can lead to congestion and other problems. If you find that your parking lot is constantly full or congested, it may be time to re-evaluate the parking lot design and layout. 

To help determine what improvements need to be made, be on the lookout for: 

  • Areas where vehicles are constantly driving or parking in the wrong direction  
  • Parking spots that are too small or too close together 
  • Lack of accessible parking or other designated parking spots 
  • One-way entrances/exits that are not clearly marked 

These are just a few things you should look for when evaluating your parking lot design. Once you have identified areas that need improvement, you can begin to map out your parking lot design. 

Big Picture Parking Lot Design Factors 

As you begin to map out your parking lot, there are a few key questions and considerations you will want to keep in mind for your parking facility. 

Questions to consider: 

  • What type of parking lot design will best accommodate the needs of your customers or employees? 
  • Are there any specific regulations or code requirements that need to be met? 
  • How can you ensure your parking lot is accessible for all users? 
  • What type of parking lot surface will best meet the needs of your parking lot? 
  • How does the setting constrain your layout decisions? 

Some of the considerations you will want to keep in mind include: 

  • The location of the parking lot in relation to your business or home. 
  • The type of vehicles that will be using the parking lot regularly. 
  • How many parking spaces you will need to accommodate all vehicles. 
  • The size and shape of your parking lot. 
  • Topography (hills, slopes, etc.) 
  • Vegetation (trees, bushes, etc.) 
  • Drainage 
  • Lighting 
  • Signage 

Once you have considered all the questions and factors above, you can begin designing your parking lot layout. There are a few parking lot layout options to choose from, which we will discuss in more detail below. 

Traffic Flow 

One of the most essential aspects of parking lot design is assessing traffic flow and how people currently park. If you find that people are parking in a way that blocks the flow of traffic, this can create a safety hazard and lead to congestion. 

To assess traffic flow, you will want to: 

  • Observe how people are currently parking 
  • Determine where the main traffic areas are 
  • Identify any areas that are being blocked by parked cars 

By understanding how people are parking and where the main traffic areas are, you can begin to make changes to the parking lot design that will improve traffic flow and reduce congestion. 

Improving Traffic Flow 

Once you have assessed traffic flow, you can begin creating a plan for it. Some of the changes you may want to make include: 

  • Changing the size or shape of parking spaces 
  • Making entrances and exits more visible 
  • Adding or removing parking rows 
  • Changing the parking lot layout 
  • Adding more parking spaces 
  • Creating one-way aisles 
  • Adding signage 

In addition, you will want to ensure that your parking lot design allows for easy pedestrian access to all businesses or buildings on the property. If people walk a long distance to get to their destination, this can cause frustration and lead to parking problems. 

By making changes to the parking lot design, you can improve traffic flow, reduce congestion, and ensure your parking lot is accessible for all. 

Parking Space Configuration 

One of the most critical aspects of parking lot design is the configuration of parking spaces. The parking space configuration will be determined by the size and shape of your parking lot and the type of vehicles that will be using the parking lot regularly.

The three most common parking space configurations are perpendicular, angle, and parallel. 

  • Perpendicular parking spaces are the most common type of parking space configuration and are typically found in parking garages and lots with multiple rows of parking. 
  • Angle parking spaces are typically found in parking lots with fewer than 30 parking spaces. 
  • Parallel parking spaces are typically found in residential areas and streets with two-way traffic. 

Deciding which parking space configuration is right for your parking lot will depend on several factors, including the size and shape of your parking lot, the type of vehicles that will be using the parking lot, and the amount of traffic in the area.  

Parking Space Dimensions 

The dimensions of parking spaces will be determined by the type of vehicles using the parking lot. The three most common types of parking spaces are standard, compact, and accessible. 

  • Standard parking spaces are typically 9 feet wide and 18 feet long and can accommodate most sedans, SUVs, and trucks. 
  • Compact parking spaces are typically smaller than standard parking spaces and are usually used for smaller vehicles, such as motorcycles, scooters, and bicycles. The dimensions of compact parking spaces are typically 16 feet long and 8 feet wide. 
  • Accessible parking spaces are designated for people with disabilities and are typically wider than standard parking spaces. Accessible parking spaces are at a minimum of 8 feet wide, van accessible spaces are eleven 11 wide, and access aisles for either type of space are five 5 feet wide.  

While compact spaces aren’t necessary, accessible parking spaces are required by law in most states. Therefore, it’s important to consider the needs of all drivers when designing your parking lot.

Parking Space Angles 

In addition to the dimensions of parking spaces, you will also want to consider the angles of parking spaces. The angled parking spaces will be determined by the type of parking space configuration you choose. 

There are four basic parking angles used for the rows of parking area stalls: 

The angle of parking spaces can have a significant impact on the efficiency of your parking lot. For example, parking spaces closer together (e.g., 30° parking angles) will result in more parking spaces in a given area but may be more challenging to maneuver for some drivers. On the other hand, parking spaces farther apart (e.g., 90° parking angles) will result in fewer parking spaces in a given area but may be easier to maneuver for some drivers. 

It’s important to strike a balance between the number of parking spaces and the ease of maneuverability when designing your parking lot. You will also want to consider the type of vehicles that will be using the parking lot when determining the angle of parking spaces. For example, if you are expecting a lot of large trucks or buses, you will want to ensure that the parking spaces are wide enough and the aisleways are clear. 

Parking Lot Signage

One of the most critical aspects of parking lot design is implementing new signage and markings to help guide drivers. If your parking lot is not clearly marked, this can lead to confusion and parking problems. 

To help guide drivers, you will want to: 

  • Add signage to indicate the entrance and exit of the parking lot 
  • Add signage to indicate the direction of traffic flow 
  • Add signage to indicate handicap parking spots 
  • Add markings on the pavement to indicate parking spots 
  • Add markings on the pavement to indicate fire lanes 

Adding signage and markings can help drivers navigate the parking lot easily and avoid unnecessary collisions or accidents.  

Loading Zones 

Another vital aspect of parking lot design and overall traffic flow is creating designated spots for loading and unloading. For example, if you have a business that relies on deliveries, it is important to have designated parking spots for delivery trucks. This will ensure that deliveries can be made promptly and that parking spaces are not blocked for other customers. 

In addition, you will want to create designated parking spots for people picking up or dropping off passengers. This can help reduce congestion and make it easier for people to find parking. 

To do this, you will want to: 

Identify areas where people are picking up and dropping off passengers 

  • Determine how many parking spots are needed 
  • Designate parking spots for loading and unloading only 
  • Add signage to indicate the designated parking spots 

Having a safe space for people to load and unload can help to reduce congestion, create safe traffic flow, and make it easier for people to find parking spots.  

Pedestrian Safety and Convenience 

Another key aspect of parking lot design is pedestrian safety and convenience. If your parking lot is not designed with pedestrians in mind, this can lead to accidents and injuries. 

To help create a safe environment for pedestrians, you will want to: 

  • Create designated walkways 
  • Add signage to indicate the designated walkways 
  • Install crosswalks or pedestrian crossing signs 
  • Add lighting to the parking lot 
  • Install speed bumps 

Taking these steps can help create a safe environment for pedestrians and reduce the risk of accidents.  

Visual Parking Lot Barriers 

If you have a parking lot adjacent to a busy street, you may want to consider adding landscaping or fencing around the parking lot’s perimeter. This can help create a visual barrier between the parking lot and the street, which can help to reduce noise and traffic. 

Consider adding the following: 

  • Trees 
  • Shrubs 
  • Flowers 
  • Fencing 

Landscaping can help to create a more inviting parking lot and reduce the amount of noise and traffic.  

Parking Lot Security 

Another critical aspect of parking lot design is security. If your parking lot is not well-lit or does not have security cameras, this can lead to crime. 

To help deter crime, you will want to: 

  • Install lighting in the parking lot 
  • Install security cameras in the parking lot 
  • Add signage that indicates the presence of a security camera 
  • If you have a large commercial parking lot, hiring a security guard can help to deter crime.  

These steps create a safe and secure parking lot for your customers and employees. 

Prepare a Preliminary Parking Layout 

Once you have considered all the above factors, you will want to prepare a preliminary parking layout. To do this: 

  • Identify the location of the parking lot 
  • Measure the size of your property (every available  
  • Determine the number of parking spots needed 
  • Plan for accessible parking spots 
  • Outline where your entrance and exits will be 
  • Follow the above outline for the rest of your parking lot layout design. 

Once you have a preliminary parking layout, you can begin to design your final parking lot layout. 

Regularly Reassess Your Parking Lot 

Once you have implemented the above parking lot design tips, you will want to regularly evaluate the parking lot to ensure it is still functioning efficiently. This can help to identify any problems or areas that need improvement. 

To do this, you will want to: 

  • Observe the parking lot during different times of day 
  • Talk to customers and employees about their experience 
  • Review parking lot security footage 

Regularly evaluating the parking lot ensures it’s functioning efficiently and effectively. 

Ultimately, there are a few key things to remember when designing a parking lot for maximum efficiency. With these parking lot design tips, you can create a parking lot that is safe, secure, and convenient for both pedestrians and drivers.
