Description: NJDOT has adopted a new data model for their transportation network. This data model was designed using portions of the ESRI UNETRANS data model, and incorporates existing data with more recent spatial and roadway inventory data. These data will encompass the NJDOT statewide road network, as well as public roads that fall outside of the NJDOT's jurisdiction. Roads were digitized using 2002 New Jersey statewide orthophotos, which were produced at a scale of 1:2400 (1"=200') with a 1 foot pixel resolution. The orthophotos were captured during February-April 2002, and were ortho-rectified to a +/- 4.0 foot horizontal accuracy at a 95% confidence level. Roads were digitized to the visible center of a street, within a tolerance of +/- 3 feet and then attributed using data collected for the Maintenance Management Systems and Local Road Inventory projects (2002-2005), which are both NJDOT BTDD data collection projects. Only public roads were digitized and attributed. Roads were digitized as divided where there was a visible, physical median separating carriageways for a length of greater than 600 feet. In the secondary direction, along median separated segments of roadway in the south and westbound directions, the milepost values are opposite to those in the primary direction. Ramps were digitized when the gore-to-gore distance was greater than 25 feet. This dataset does not include address range attributes. The project began in November 2003, and was completed by May 31, 2005.
