Relieving Parkway Congestion

Dr. Lazar Spasovic, executive director of NJIT's International Intermodal Transportation Center, led a study of congestion on the Garden State Parkway.

NJIT's International Intermodal Transportation Center (IITC) assisted the New Jersey Department of Transportation in developing the "Congestion Relief Plan for the Garden State Parkway."  The study, led by Lazar Spasovic, professor of management and transportation and executive director of IITC, highlights traffic congestion impacts as part of the development of the ten-year plan to remove toll barriers on the Garden State Parkway.

Findings included:

  • Eliminating the Raritan Toll Plaza in the southbound direction would reduce peak evening by two minutes or more per vehicle. 
  • Widening of the Driscoll Bridge would aid in the significant reduction.
  • Eliminating the Union southbound and Essex northbound toll plazas would offer minimal impacts.
  • Eliminating the Bergen Southbound and Hillsdale Northbound toll plazas would offer a reduction of one minute per vehicle.
  • A "one-way" toll system would provide significant travel time reductions.
  • Traffic operations between high speed E-ZPass and complete elimination of the toll plaza would reflect very little difference.
