4D Drive-Through Visualization of I-280 for Review of Proposed Signing

摘要

The primary objective of this work was to produce a simulated 4D Drive-through of211u001ea portion of highway (I-280 through Newark, NJ) for which proposed signing for 211u001ethe Performing Arts Center, Penn Station and other traffic generators in the City 211u001eof Newark had to be reviewed. In addition to reproducing the existing road in a 211u001e3D model, a plant for an exit ramp connecting I-280 to Route 21 in Newark, NJ was 211u001ealso constructed in the 3D model. Using a simulated 4D drive-through, reviewers 211u001efrom NJDOT Traffic Engineering and a public task force were able to see the 211u001esigning from the point of view from a driver traveling along the roadway at 211u001enormal traffic speeds. The drive-through visualization was used to help identify 211u001epotential problems regarding excessive density of signing and inadequate sight 211u001edistances for signing prior to physical installation of the signs. The 3D 211u001egeometrical model of the roadway, shoulders, signs, intersecting bridge 211u001estructures, and other objects of significance were constructed based on available 211u001edata such as GPS and video log information.
