Parking has become one of the biggest problems in modern cities. When the vehicle growth rate is faster than street development rate, there will be issues with how these vehicles will be parked. A smart parking system becomes an alternative solution to addressing parking problems.

In general, a smart parking system will address problems shown in the following figure:

• Vehicle In/Out stands for detecting when a vehicle comes in and goes out. It will affect the number of vacant parking spaces and parking duration.
• Vehicle plate number detection aims at minimizing human errors in entering vehicle plate numbers into a system.
• Vacant parking space aims at optimizing parking space by knowing the number of vacant parking spaces.
• Parking management system is the main system to manage all activities in a parking system. It also provides information about vacant parking spaces to users through a website and mobile application.

In this chapter, we will explore several problems in parking systems and address them using automation.
