Crossing Inventory Data Integrity

Integrity of inventory data in TRIMS is extremely important. Some of the uses of the crossing data include:
  • Prioritization of at-grade crossings for safety upgrades under the
    Section 130 program
    .
  • Prioritization of at-grade crossings for grade separation under the RGS Program.
  • Various reports needed for state and federal government.
Some critical data at each at-grade crossing requiring regular updating includes:
  • Train counts (through and switching).
  • Minimum and maximum train speeds.
  • AADT.
  • Special vehicle movements.
  • Percent trucks.
  • Roadway speed limit.
  • FRA reported crash history.
Other data requiring updates after a project impacting the crossing is completed includes:
  • Crossing status (open, closed, abandoned, out of service or under construction).
  • Crossing type (public, private or pedestrian).
  • Crossing position (at-grade, railroad over
    or
     railroad under).
  • Roadway type (one-way or two-way).
  • Types and quantities of warning devices.
  • Presence of medians or channelizing devices.
  • Presence of
     adjacent intersections or traffic signals.
  • Number of tracks at crossing.
  • Crossing surface type.
  • Crossing length.
  • Quiet Zone
    presence
    .
  • Number of lanes at crossing.
  • Truck lane
    (if applicable)
    .
  • Number of sidewalks at crossing.
  • Roadway surface.
  • Roadway width.
  • Shoulder type and width.
  • Signs at crossing and on approaches.
  • Pavement marking and illumination information.
  • ENS information.
  • Clearance restriction (if applicable).
  • Highway functional class.
  • Area land use and development type.
  • Stopping sight distance and related information for passive crossings.
  • Changes to rail lines (removals, additions and relocations).
  • Photos of crossing.
Any changes to rail line data are coordinated through TPP for updates to the statewide rail map and server that links to TRIMS to reveal this information.
Crossing data found in TRIMS that does not typically require updating includes:
  • DOT Number.
  • Roadway approach directions.
  • Railroad company, division, subdivision, and milepost.
  • Highway and street name.
  • City, county and TxDOT district.
  • NBI bridge number.
  • Latitude, longitude, and elevation.
  • Crossing angle.
  • Track orientation direction.
  • Adjacent crossing information.
