Fundamentals of Transportation/Analogs

Transportation networks have analogs with network processes in other systems, such as water networks, structures, and electrical networks. Some of the relationships are outlined below.

Structures

 * F= force
 * m = Mass
 * a = acceleration
 * T = Time

Transportation

 * q = flow
 * k = density
 * v = velocity

Electricity

 * V= Voltage
 * I = Current
 * R = Resistance
 * G = Conductance = 1 / Resistance

Water

 * P = hydrostatic pressure
 * ρ = fluid density =mV = mass *volume
 * g = acceleration due to gravity
 * h = height
 * c= constant
 * A = area
