Growth Factor Solution

STEP 0: Pre-Calculation Summary

Formula Used

Growth Factor = Number of Future Trips in the Zone/Number of Current Trips in that Zone
f_i = T_i/t_i
This formula uses 3 Variables

Variables Used

Growth Factor - Growth factor depends on the explanatory variable such as population of the zone , average house hold income , average vehicle ownership.
Number of Future Trips in the Zone - Number of future trips in the zone is the product of number of current trips in that zone and the growth factor.
Number of Current Trips in that Zone - Number of Current Trips in that Zone is the present number of trips in the particular zone.

STEP 1: Convert Input(s) to Base Unit

Number of Future Trips in the Zone: 6 --> No Conversion Required
Number of Current Trips in that Zone: 18 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

f_i = T_i/t_i --> 6/18

Evaluating ... ...

f_i = 0.333333333333333

STEP 3: Convert Result to Output's Unit

0.333333333333333 --> No Conversion Required

FINAL ANSWER

0.333333333333333 ≈ 0.333333 <-- Growth Factor

Average Vehicle Ownership for Current Year

Go Average Vehicle Ownership for Current Year = (Population of Zone for Design Year*Average House-Hold Income for Design Year*Average Vehicle Ownership for Design Year)/(Growth Factor*Average House-Hold Income for Current Year*Population of Zone for Current Year)

Average House Hold Income for Current Year

Go Average House-Hold Income for Current Year = (Population of Zone for Design Year*Average House-Hold Income for Design Year*Average Vehicle Ownership for Design Year)/(Growth Factor*Population of Zone for Current Year*Average Vehicle Ownership for Current Year)

Average House Hold Income for Design Year

Go Average House-Hold Income for Design Year = (Growth Factor*Population of Zone for Current Year*Average House-Hold Income for Current Year*Average Vehicle Ownership for Current Year)/(Population of Zone for Design Year*Average Vehicle Ownership for Design Year)

Average Vehicle Ownership for Design Year

Go Average Vehicle Ownership for Design Year = (Growth Factor*Population of Zone for Current Year*Average House-Hold Income for Current Year*Average Vehicle Ownership for Current Year)/(Population of Zone for Design Year*Average House-Hold Income for Design Year)

Population of Zone for Current Year

Go Population of Zone for Current Year = (Population of Zone for Design Year*Average House-Hold Income for Design Year*Average Vehicle Ownership for Design Year)/(Growth Factor*Average House-Hold Income for Current Year*Average Vehicle Ownership for Current Year)

Population of Zone for Design Year

Go Population of Zone for Design Year = (Growth Factor*Population of Zone for Current Year*Average House-Hold Income for Current Year*Average Vehicle Ownership for Current Year)/(Average House-Hold Income for Design Year*Average Vehicle Ownership for Design Year)

Simple Expansion Factor

Go Simple Expansion Factor = Total Number of Household/(Total Number of Addresses-Number of Samples)

Previous Total Number of Trips using Doubly Constrained growth Factor Model

Go Previous Total Number of Trips = Total Number of Trips/(Growth Factor A*Growth Factor B)

Doubly Constrained Growth Factor Model

Go Total Number of Trips = Previous Total Number of Trips*Growth Factor A*Growth Factor B

Number of Future Trips in Zone

Go Number of Future Trips in the Zone = Number of Current Trips in that Zone*Growth Factor

Number of Current Trips

Go Number of Current Trips in that Zone = Number of Future Trips in the Zone/Growth Factor

Growth Factor

Go Growth Factor = Number of Future Trips in the Zone/Number of Current Trips in that Zone

Uniform Growth Factor

Go Uniform Growth Factor = Expanded Total Number of Trips/Previous Total Number of Trips

Previous Total Number of Trips

Go Previous Total Number of Trips = Total Number of Trips/Uniform Growth Factor

Expanded Total Number of Trip

Go Total Number of Trips = Previous Total Number of Trips*Uniform Growth Factor

Growth Factor Formula

Growth Factor = Number of Future Trips in the Zone/Number of Current Trips in that Zone
f_i = T_i/t_i

Are Growth Factor suitable for Long Term?

Growth factor model is a method which respond only to relative growth rates at origins and destinations and this is suitable for short-term

How to Calculate Growth Factor?

Growth Factor calculator uses Growth Factor = Number of Future Trips in the Zone/Number of Current Trips in that Zone to calculate the Growth Factor, Growth factor depends on the explanatory variable such as population (P) of the zone ,average house hold income (I) , average vehicle ownership (V). Growth Factor is denoted by f_i symbol.

How to calculate Growth Factor using this online calculator? To use this online calculator for Growth Factor, enter Number of Future Trips in the Zone (T_i) & Number of Current Trips in that Zone (t_i) and hit the calculate button. Here is how the Growth Factor calculation can be explained with given input values -> 0.333333 = 6/18.

FAQ

What is Growth Factor?

Growth factor depends on the explanatory variable such as population (P) of the zone ,average house hold income (I) , average vehicle ownership (V) and is represented as f_i = T_i/t_i or Growth Factor = Number of Future Trips in the Zone/Number of Current Trips in that Zone. Number of future trips in the zone is the product of number of current trips in that zone and the growth factor & Number of Current Trips in that Zone is the present number of trips in the particular zone.

How to calculate Growth Factor?

Growth factor depends on the explanatory variable such as population (P) of the zone ,average house hold income (I) , average vehicle ownership (V) is calculated using Growth Factor = Number of Future Trips in the Zone/Number of Current Trips in that Zone. To calculate Growth Factor, you need Number of Future Trips in the Zone (T_i) & Number of Current Trips in that Zone (t_i). With our tool, you need to enter the respective value for Number of Future Trips in the Zone & Number of Current Trips in that Zone and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
