Attributes
4
What is an Attribute“A piece of information that determines the properties of a field or tag in a database or a string of characters in a display.”
Examples of attributes at TxDOT:
• The number of lanes open to traffic along a length of highway
• The number of vehicles that travel along a length of highway
How Many AttributesWith the help of District roadway inventory coordinators, TPP - Data Management maintains 200+ attributes along 313,656 miles of
roads in Texas.
Where is the Data StoredGeospatial Roadway Inventory Database (GRID)
• GRID is the Data Warehouse for federally reported GIS linework and attributes
Problems Associated with Attributes?• Should be clearly defined and accessible to users
• Reviewed and updated regularly
• Change frequently along a route
• Requires location

Locations

How do you Determine Location?• TPP – Data Management uses construction plans, aerial photography, and GPS to manage GIS linework
• Latitude/Longitude values are the underlying base reference
• Distance from Origin (DFO) values are calculated based on feature length
• GIS linework is passed to GRID where users manage Linear Referencing Systems (LRS) and 200+ attributes
• Control Section
• Reference Marker

Systems

Attributes and Locations Define SystemsAttributes and roadway locations are used to highlight different parts of the roadway network. We call them systems
but they are simply subsystems of the overall roadway network.
Examples of Systems• National Highway System
• Texas Trunk System
• Hurricane Evacuation Routes
• Functional Classification System
• Freight Network
• Energy Sector Network
• County Road Network
• Local Street Network
In each instance, a collection of attributes along with roadway location defines when a particular length of roadway
participates in a system.

Reports
7
Attributes and Locations SummarizedAt the end of the reporting year, we summarize the full body of attributes and location information into a series of reports. These
reports are made available on TxDOT.gov and are the basis for all inventory related public information requests and statewide
analysis within the next data year. The federal reporting deadline is June 15th.
Standard Reports• Highway Performance Monitoring System (HPMS), key ingredient for motor fuel tax reimbursements from FHWA
• Annual Reports (PDF and GIS Version)
• Multi-Year Roadway Data Tables (Excel Version)
• County Road Inventory

Applications allow users to visualize and query Attributes, Locations, and SystemsThink of applications as the finish line. All the work by Districts and TPP – Data Management maintaining the roadway inventory
attributes, locations, and systems is put to use in applications.
Applications Available to the Public:
• Statewide Planning Map
• Open Data Portal
• ArcGIS Online
• Project Tracker

Why does Project Tracker ExistWhen Senate Bill 1420 passed in 2011 during the 82nd Legislative Session, the intent was for the Texas Department of
Transportation (TxDOT) to become a more accountable, informative, and transparent agency. To achieve this goal, TxDOT created
Project Tracker, a website for the general public and stakeholders to track TxDOT transportation projects.
Where does Project Tracker get Data
• Design and Construction Information System (DCIS)
• Primavera (P6)
• Site Manager
• PeopleSoft
• ArcGIS Online (AGO)
*** If data is incorrect in Project Tracker it’s also incorrect in the parent system ***
Key Points
• Project scores and locations are updated weekly
• Control Section Job based (CSJ, not CCSJ)
• 12,000+ Projects in the system
• Available to the public
