Abstract

In this study, an estimation model of the intrazonal work trips is developed on the premise that all employed persons decide their work places first and then they choose their residential locations. As a consequence, the model comes to be based on the density of employed persons at work zone. The estimation model is distinguished by the following properties; (A) the ratio of the intrazonal work trips and the number of employed persons at a work zone falls as the density of employed persons at the same zone, (B) the ratio rises as the zone area increases in size and it comes up to 1 when the zone area becomes infinite, (C) the ratio falls as the density of the transportation network in an urban area rises and the travel speed increases. The intrazonal work trips estimated by the model fairly fall in a line with the actual ones.
