Land use, consisting of demographic and economic data, is directly related to the transportation network. More housing and commercial development often creates congestion on local roadways. Likewise, the decrease of population and business activity in an area can create problems on the existing transportation system. Therefore, Eastgate maintains and monitors the land use throughout Mahoning and Trumbull Counties. The data itself is collected by traffic analysis zones and used in Eastgate’s transportation modeling process. Existing and projected land use data are used by Eastgate to view current and future travel patterns. Data collected includes population, housing units, school enrollment, labor force, vehicles and employment by sector.
