2 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 2

3 How is Data Used? And By Whom? Engineering Engineering Economy Environmental Analysis Finance Legislation Maintenance Operations Planning Safety Statistics Legislature Governor County Judges Federal Highway Administration (FHWA) TxDOT Districts TxDOT Divisions Universities Public 3

4 Historical Perspective From the early days to today 4

5 First traffic maps published for Legacy Traffic Map 5

6 Key Points 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. 6

7 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 7
