This paper investigates the application of advanced detection, traveler information, and advanced signal control systems to reduce congestion and incidents at railroad crossings. The study uses a traffic simulation model, TRAF-CORSIM, to evaluate the most effective scenario using ITS to alleviate railroad crossing problems; the Fargo-Moorhead metropolitan area was used as a case study. A typical system layout includes a train detection system that triggers a "train present signal phasing" and provides information to motorists, through Variable Message Signs (VMS), to take alternative routes. The results of the simulation indicate significant improvements in traffic conditions under the proposed ITS scenario.
