Committee member cites anomalous speed-trailer readings on 3rd Street

A committee member told the Stewartville City Council that speed-trailer data collected from deployments on 5th Avenue and 3rd Street showed several implausible high-speed readings and that the sheriff’s office has been informed.

The committee member said the trailer on 5th Avenue showed an average speed of about 28 mph, which the speaker described as “normal.” By contrast, the speaker said the device logged multiple entries on 3rd Street “that are listed at a 100 to a 150 miles an hour” and repeated that “there’s 10 of them that are listed at a 100 to a 150 miles an hour,” adding that some entries were recorded at 124 and 139 mph. The speaker characterized those extreme values as likely errors and said the device will remain deployed to collect more data.

According to the speaker, some individual readings (one listed at 85 mph) appeared plausible while dozens of others seemed inconsistent with what could be expected on neighborhood streets. The committee member told the council that the sheriff’s office has been made aware of the readings and encouraged residents to report license plates for persistent complaints at specific locations.

The council did not take formal action during the discussion; the reported next steps were continued monitoring of the trailer and coordination with the sheriff’s office to verify data and address speeding complaints. No enforcement measures or specific follow-up deadlines were announced at the meeting.

The committee member who reported the data is identified here by role only because the transcript does not explicitly state a personal name for that speaker.
