  8. Criteria to Close Crossing(one or more) • Nearby crossing is available w/ acceptable access • Cost to upgrade the crossing exceeds cost of an acceptable alternate access • Combination of low volume, close alternative access, and limited increase in trip length • Crossing blocked excessively by train but not feasible to grade separate Source: GUIDANCE ON TRAFFIC CONTROL DEVICES AT HIGHWAY-RAIL GRADE CROSSINGS – HIGHWAY/RAIL GRADE CROSSING TECHNICAL WORKING GROUP (TWG), November 2002

  9. Criteria for Grade Separation(one or more) • Part of Interstate Highway System • Limited access • High vehicle speed or volume • High train speed or volume • Combination of train and vehicle volume (exposure) • Expected accident frequency (EAF) • High vehicle delay / Poor LOS Source: ibid.

  10. At Grade Alternatives • Backup queue detectors • Advance arrival and delay information • In pavement flashing lights • Vehicle arrest barrier • Changeable message signs • Access and turn prohibitions • Customer education

  11. Grade Separated Alternatives • Full separation over • Partial separation over • Full separation under • Partial separation under

  12. Design Constraints Limited right of way Access to adjacent properties High water table Min. railroad clearance Utilities Wetlands Future roadway widening

  13. Three Alternatives Evaluated Full Grade Separated: Entire Athens Avenue / Industrial Avenue intersection elevated
