Parking guidance systems recommend drivers with convenient command over parking system with fabulous characteristics and attributes. Modern parking utilizes different advance technologies to assist motorists find available and unoccupied spaces. It helps drivers diminish traffic jam linked to parking and amplify the infrastructure efficiency.

The modern day parking system gives a unique method of vehicle detection using an ultrasonic sensor. The ability to reliably detect vehicles offers certain advantages for asset management, resource allocation, site safety and traffic control.
