Car drivers spend a significant amount of time looking for parking spaces in cities. The waiting time can be longer in cities with a high population and shorter in areas with a low population. However, it's not only the time that is wasted while looking for parking spaces, but also the greenhouse gas emissions that come from vehicles and the wastage of fuel. 

Cities worldwide are implementing smart parking systems to minimize traffic congestion, pollution, and parking issues. The autonomous parking market is set to grow to $12.9 billion by 2030 at a CAGR of 25.2%, which shows the impact smart parking systems will have in the next few years. 

What is a Smart Parking System?

A smart parking solution or connected parking system is a centralized management system that allows drivers to search for and reserve parking spaces using the software application on their smartphone(s). 

The purpose of smart parking solutions is to increase parking's effectiveness and convenience for both city management and users. These features include dynamic pricing, automatic payment systems, and reservation capabilities. Smart parking uses data and technology to make urban environments more sustainable, efficient, and user-friendly.

The hardware consists of sensors that detect available parking spaces and send that information to drivers. The sensors communicate with a system so that all information about availability is updated in real time, so drivers never have to question availability. 

Multiple sensors installed in parking spaces collect data, which needs to be managed by robust software. A parking system can only function accurately if the IoT devices send precise, uninterrupted data.

How Does Smart Parking System Work

Smart parking systems are installed in various locations, inside buildings like offices and malls, as well as outdoor public spaces. Each sensor detects a vehicle’s entry, identifies available parking spots, and transmits this data to a mobile app or cloud-based software. The system provides real-time updates on parking availability, showing open spots for each structure. It collects data from every sensor across the facility and typically refreshes the information every five minutes.

1. Role of Sensors in Parking Systems

Sensors are installed in parking lots to detect the occupancy or vacancy of a space. They send this information to cloud-based software, which further processes the information and offers parking operators information on users' usage patterns. The software also allows drivers to locate available spots via mobile apps or digital signage installed within the parking lots.
 
IoT plays a crucial role in linking devices and technologies to provide smooth communication between sensors, software, and end-user applications. 

Types of Sensors used in Parking Systems

Ground Sensors: These are typical embedded devices installed in each parking space. Electromagnetic or infrared technology is used in these sensors, but their purpose is to detect the presence of a car on the spot. The moment a car enters, it is sensed and reported to the central system as an "occupied" status, while the vehicle's exit is reported as a "vacant" status.

Overhead Cameras: These cameras are used in ceiling or on-light-pole installations for bigger facilities. They are equipped with image recognition technology to track the status of parking spaces in real-time, analyzing video streams to discriminate between empty and occupied spaces.

Other Sensors: This third group comprises ultrasonic sensors, which detect vehicles using sound waves, and radar sensors, which cover much larger areas and help monitor traffic flow into and out of parking lots.

2. How Data Moves Through the System

In a smart parking system, real-time data movement is at the heart of seamless functionality. The process starts with sensors installed in each parking space. These sensors detect the presence or absence of vehicles and send the data to an intermediary gateway device via a secure wireless connection.

The gateway then transmits this raw data to a central management system either a local server or a cloud-based platform that acts as the system’s brain. This platform processes, stores, and distributes the information instantly.

As vehicles move in and out, the system continuously ingests and updates data, allowing parking operators to monitor space occupancy in real time. Simultaneously, this information is shared with drivers through mobile apps or digital signage, helping them quickly locate available spots.

This real-time data transmission and processing ensures fast, responsive parking operations. It reduces congestion, improves space utilization, and enhances the user experience. The entire ecosystem relies on smart parking management software, often custom-built by expert development teams like Ditstek Innovations (DITS) to ensure smooth integration between sensors, software, and user-facing applications.

3. Cloud Storage of Data

Cloud storage offers scalable storage solutions and remote access to data derived from sensors and a central parking management system. It helps parking operators access real-time information for monitoring operations. The cloud also allows integration of third-party services such as smartphone applications and payment gateways, which can be integrated only by an expert software development team. 

At DITS, in addition to software development, we also offer software integration with mobile apps and other applications for businesses that prefer managing everything from a single platform. Integration enables businesses offering parking services to check real-time information, make informed decisions, and offer better customer service. 

4. Data Analytics

Parking operators use advanced analytics to extract value from the vast amounts of raw data derived from sensors and other technology. With the right tools, we can see data-transformed patterns and trends that lead to insights to improve parking management. 

Data analytics tools will analyze and process the collected data in real-time and identify patterns for all the above metrics. The resulting data provides operators with an accurate picture of parking demand, allowing adjustments in spatial effectiveness. For example, if the analytics show that certain parts of a facility are being underused, they can redirect them to be utilized with digital signage or apps.

5. Data Security

With a large amount of data transfer from sensors and devices to the central parking management system and cloud, data encryption and protection become essential. Smart parking systems use encryption to protect this data when it is received and transmitted from sensors to the gateway to the cloud. 

This means that sensitive information like a payment or vehicle identification, does not remain exposed to a potential cyber compromise during the transmission. The security protocol could also provide a form of protection against hack attempts and ransomware threats to maintain a safe and trustworthy parking experience for users and operators. 

At DITS, we consider data security a priority while working on any software development project. From the first communication with a business to development of software, to final deployment and ongoing maintenance, we use security measures that offer high-end data protection and adhere to compliance and industry standards.

6. Predictive Analytics

Predictive analytics is the next step, which uses historical data to forecast future parking trends. Using previous historical data on parking activity and predictive models, we are able to forecast future activity by identifying times that indicate a prevailing trend based on its frequency and starting point. This can help adjust staffing needs, determine whether to open additional lots, or employ dynamic pricing. 

Dynamic pricing can assist in maximizing revenue and can drive down pricing when there is low demand. During peak time, prices are higher, allowing the use of space to peak grid capacity to smooth out vehicle usage by collecting revenue or redistributing demand with lower pricing.

7. Mobile App Integration

A critical part of any smart parking system is the mobile app interface. These apps allow drivers to check real-time availability, reserve spots in advance, make digital payments, and even navigate directly to vacant spaces. The app connects to the central parking management system, ensuring users get accurate, up-to-date information wherever they are.

Mobile app integration also benefits operators by providing data on user behavior, peak hours, and payment trends. With seamless communication between backend systems and the front-end app, the parking experience becomes faster, easier, and more user-friendly.

8. The Role of Expert Software Developers

While sensors and hardware form the physical infrastructure, it’s the software that brings the entire smart parking system to life. From real-time data processing and secure cloud integration to mobile app functionality and predictive analytics, every element relies on well-architected software to run smoothly.

That’s why businesses turn to experienced development partners like Ditstek Innovations (DITS).
