Applications
Intelligent Car Parking System
• Problem - finding a vacant car parking space in a big parking area.
Wastage of time Wastage of fuel Air pollution Driver frustration
14
Intelligent Car Parking SystemMotivation• Provide customers within a
parking lot the ability to quickly and easily find an available parking space.
• Provide a proper indication if there were no remaining parking spaces.
• Customers - save time and fuel.• Owner -maximize the number of people
able to park in a given area.15
