Overview: Why is STARS II important?
STARS II – Statewide Traffic Analysis and Reporting System II
Federal requirement for all State DOTs to develop, establish, implement, and continue operation of Traffic Monitoring System
Transportation Planning and Programming Division (TPP) is OPR for collection, analysis, and reporting of traffic data
TxDOT’s current annual budget investment for collecting traffic data: Approx. $5,000,000
TxDOT has an obligation to use, make available, and preserve collected traffic data

Critical factors of Data:
Availability – Data must be able to be collected and obtained in a meaningful context.
Quality – Data must be considered trustworthy and reliable by end users.
Accessibility – Data must be in a format or context that is meaningful and usable.

STARS II – “We’ve come a long way!”
Subsystems integrated into one a single web-based platform an advancement from the legacy mainframe & PC-based applications used in the past
QA/QC ability enhanced to overcome manual processes prone to error
Improved, interactive visual, spatial analysis of traffic stations and roadways in lieu of hard copy maps
Increased precision in factoring, ad hoc reporting, & developing statistics that weren’t previously available
Improved transparency and auditability
Provides greater accessibility and facilitates more open communication regarding traffic data

Where the Data Starts… Traffic data, which is collected and subsequently analyzed, is used for a wide variety
of purposes and populates the Highway Performance Monitoring System (HPMS), which is a key FHWA support process.
Pneumatic Tube Counts
Collect annually for on-system roadways statewide
Collect every five years for off-system roadways on a rotating cycle by District
75,000–85,000 Locations
Manual Classification Counts
Collect annually for on-system roadways statewide
Collect to supplement continuous counter classification data especially in urban areas where continuous counter sites are not possible due to congestion
800 Locations
24/7/365
369 Sites Statewide
Depending on the type of sensor installed, collect traffic data in the following categories:
Volume
Classification
Speed
Weight
Short-Term Traffic Monitoring – Part I
Short-Term Traffic Monitoring – Part II Continuous Counters
