THE IMPACT OF EXOGENOUS VARIABLES ON PRECISION FOR TRANSPORTATION DEMAND FORECASTING

Abstract

It's important to predict future travel demand correctly in urban transportation planning.
The forecast of Exogenous Variables, e. g. population, economic activity, and land use, is the first step of future travel demand forecasting process. But, we have been not necessarily interested the reliability of the estimated exogenous variables and their impacts on travel demand in future.
In this paper, the after study on the above mentioned subjects. was carried out through SENDAI Area Transportation Study, 1972.
As a result, the importance of exogenous variables in urban transportation planning is made sure, and the improvement points of forecasting method of these variables are suggested.
