Travel demand forecasting
- Travel Demand Forecasting is the process used to predict travel behavior and resulting demand for a specific future time frame, based on assumptions dealing with landuse, the number and character of tripmakers, and the nature of the transportation system.
- It is basically a computer dependent mathematical process founded on the present day observations whereby future travel patterns can be predicted.
- It involves developing mathematical formulae which given the details of household structure, income, car ownership, etc. in the study area can produce present day travel patterns as surveyed.
Use of a tool such as the travel forecasting model can help the policy-maker make an informed decision. The travel forecasting model consists of four basic steps:
- Trip generation
- Trip distribution
- Modal split
- Route assignment
Trip generation Determining how many trips will the population, employment, etc. of study area generate ? |
⇓
Trip distribution Determining origin and destination of the trips |
⇓
Modal split Determining mode of travel like car, bus, autorickshaw, etc. |
⇓
Route assignment Determining actual routes used for trips |
