LTA maintains a real-time incident database covering the Houston-Galveston region, with incident data updated every two minutes. This provides a distinct view of localized crash patterns that are not reflected in annual government reporting through sources such as TxDOT's Crash Records Information System (CRIS), which publishes aggregated data on an annual basis.
The data accumulated at I-45 S & N Main over recent months documents a consistent pattern of multi-incident density that distinguishes this location from typical freeway segments. The scale—64 incidents in 30 days—reflects a concentration that statistically separates this corridor from regional averages and warrants attention from both transportation officials and motorists who use this route regularly.
