Abstract
This paper presents the results of a study for the Nanaimo Parkway, presently under construction west of the City of Nanaimo, B.C., where travel demand forecasts for a four-lane expressway was required. The paper begins with a description of the Nanaimo Parkway (located west of the City of Nanaimo, B.C.), a project requiring travel forecasts without the aid of a current transportation planning model. This paper discusses the application of traffic impact study methodology in assessing future local traffic; the major problems with the use of this method; and measures taken to resolve these problems. Also discussed are the other components of existing and future traffic volume identified, and the methods used to estimate them. (A)
