About Base Demand Forecast Index

The Base Forecast Index is mandatory for any field targeted for use in demand forecasting. This value, a floating point number between 1 and 10, is a measure of how the total and density for that field affects demand for transit.

An example is vehicle ownership. For example, if there were more vehicles per household, there will be less demand for public transit. Households without a vehicle would have a base index of 10, that is, the residents would be more likely to use transit. Conversely, households with two vehicles would have a low base index (for example, 1 or 0), that is, the residents would be unlikely to use transit.
