Sponsored research — TTI corridor program
A web-hosted summary of corridor program work, written for sponsors and the public. Distinct from the printed quarterly: this version lives at a permanent URL and updates between print cycles.
Executive summary
FY26 Q1 closed with awarded funding 12.4% above the same quarter in FY25, driven primarily by a $9.2M IH-35 corridor-safety renewal from TxDOT and a $4.8M FHWA work-zone classifier grant. Headcount on sponsored projects rose 6.1%; equipment capex held steady.
The headline metric: 412 active projects across the corridor program, a record for the institute in any single quarter.

TxDOT share
Crash-rate reductions held in three of four corridors under active retrofit; the fourth (US-290 between Hempstead and Brenham) showed a 4% rise associated with construction-zone congestion, consistent with modeling. The interim signage refresh is on track for completion in the May steering review.
Methods
All metrics use TxDOT CRIS-2 records joined against the TTI corridor classifier. Confidence intervals are bootstrap percentile (B = 2,000) at the 95% level.
Data and methods
Source datasets, classifier versions, and reproducibility pointers live in the program's Landscape workspace. Sponsor access is provisioned via Entra ID; public extracts are published to data.tti.tamu.edu in CSV and Parquet.
What's next
Q2 work continues on the classifier-refresh roadmap and the FHWA work-zone deliverables. The next public update lands at the end of the fiscal quarter.
