Section 2: Texas Railroad Information Management System (TRIMS)

Anchor: #i999730

Overview

TxDOT has adopted TRIMS as a statewide database for tracking various data related to rail-highway applications. TRIMS is a geospatial database which employs roadway maps and satellite images from Microsoft Bing and Google, as well as rail line data from TPP.

Some of the features of TRIMS include:

    Anchor: #WGBDOKOB
  • A crossing inventory module including photographs of each crossing.
  • Anchor: #HKJBKCNO
  • A project management module for tracking rail-highway projects and tying these to the crossing inventory via DOT numbers.
  • Anchor: #MPLMDGJB
  • Ability for TxDOT users to edit inventory and project data.
  • Anchor: #PKNHYBAG
  • Ability to view which data has been edited over time.

TRIMS Versions

There are two versions of TRIMS with various capabilities:

CoreTRIMS

The most advanced version of TRIMS, CoreTRIMS, allows users to view and edit data in both the crossing inventory and project management modules, depending on user access. CoreTRIMS is accessed on TxDOT workstations only.

FieldTRIMS

FieldTRIMS is a mobile data collection tool that does not need connection with the central TRIMS database. Users can update crossing inventory and take photos of crossings in the field. Later this data is synced with the central TRIMS database when internet service is available.

NOTE: The WebTRIMS module was retired.

Crossing Inventory Data Integrity

Integrity of inventory data in TRIMS is extremely important. Some of the uses of the crossing data include:

    Anchor: #TGQQBMRH
  • Prioritization of at-grade crossings for safety upgrades under the Section 130 program.
  • Anchor: #VCUVBMCA
  • Prioritization of at-grade crossings for grade separation under the RGS Program.
  • Anchor: #PQFHBEWV
  • Various reports needed for state and federal government.

Some critical data at each at-grade crossing requiring regular updating includes:

Other data requiring updates after a project impacting the crossing is completed includes:

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:

Crossing Data Responsibilities

On an annual basis or as railroad capital improvement projects are completed, railroad companies should submit to RRD accurate:

RRD receives annual updates from Transportation Programming and Planning (TPP) to:

This information may be found on the Statewide Planning Map maintained by TPP.

RRD typically receives updates from districts on:

Average daily traffic in TRIMS is calculated using either the AADT estimation provided by TPP or by a Programmed Annual Average Daily Traffic (PAADT) if available. A PAADT is an actual count performed in the field by either TxDOT or local government. Since a PAADT represents actual counts taken, the PAADT is used in lieu of the AADT for the purposes of performing FSP or RGS program rankings.

RRD updates crash data monthly in TRIMS based on data found within:

Crash Records Information System (CRIS)

CRIS is a statewide database used for filing police reports for crashes on any public roadway in Texas. CRIS can serve as a separate source of data for verifying crash data provided in the FRA database. CRIS data is not currently incorporated into TRIMS.

Crash reports may be obtained online.

TRIMS Project Management Module

The project management module in TRIMS includes information for all types of rail-highway projects. Some data in the project module includes:

RRD and district railroad coordinators share responsibility for project updates in TRIMS. RRD creates the projects, adds basic project information and steps, and typically uploads any agreement information and Completion Checklists to the project. Work Orders, inspection diaries, approved invoices, and Completion Letters are uploaded by districts.

Only TxDOT users have access to the TRIMS project management module. Consultants working on RRD projects may be allowed access to TRIMS on a case-by-case basis.
