K-value K-value is the constant ratio between two orders of central place in an urban hierarchy According to Christaller, there are three kinds of hierarchy in different k-value Marketing principle : k-value = 3 Transport principle : k-value = 4 Administration principle : k-value = 7

Transport principle : k-value = 4

Administration principle : k-value = 7
