What the monitor recorded
Traffic was heavier by day.
Recorded speeds were higher at night.
85.0% not flagged by the device. The export flags 11,111 of 74,040 passages. “Flagged” refers to its #violators field; it is not a verified count above 35 mph.
A higher device-flagged share at night. From 10 PM to 6 AM, 51.9% were flagged by device, compared with 10.6% during the day.
Counts and rates tell different parts of the story. Daytime had more device-flagged passages in total: 6,998, compared with 4,113 at night.
Correction to earlier materials: the export’s #violators field was previously labeled “above 35 mph.” That interpretation is not verified. Twenty-six intervals contain flags despite a peak at or below 35 mph. This report preserves the original counts as device flags; it does not infer speeding or compliance from them.

Keep the count in view.
Both bars use the same 0–100% scale. The nighttime percentage describes a smaller traffic stream.

Every hour has a different pattern
Two aligned charts separate traffic volume from the share flagged by device.
Shaded hours: 10 PM–6 AM. Hourly volume is the average across all 25 monitored dates, including the two partial days.
02 / Daily & weekly patterns
See the variation across the period.
Compare complete days with care: March 31 and April 24 contain partial-day recordings.
Daily traffic
Dark bars: not flagged by device. Orange bars: flagged by device. Asterisks mark partial days.
Day of week
Weekday device-flagged share: 14.1%. Weekend share: 18.1%.
Each weekday appears three or four times. Tuesday and Friday include a partial day. This is a description of this reporting period.

Gray cells have no recorded passages. A high percentage may describe a small count; check the selected cell’s denominator. Times follow the device export.

A passage-weighted average
Sum of the export’s per-passage average speeds divided by recorded passages. It does not show the full spread of speeds or establish speed-limit compliance.

77 mph
One interval’s maximum
April 24, 06:00–06:30. The interval contained 75 passages, including 25 device flags. A recorded maximum is not a typical-speed estimate.

These are interval counts, not counts of vehicles at each speed. Thresholds overlap: an interval with a 60+ mph peak also appears in the 45+, 50+ and 55+ groups. Bars use a common 0–100% scale.
05 / Thirty-minute detail
Keep exceptional readings
in context.
Times are interval starts. “Flagged” is a passage count. Rate rankings include only intervals with at least 30 recorded passages.
Ten highest recorded peaks
All dates are in 2026. Peak is the interval maximum.

These are selected extremes, not a representative sample. Flags retain the export’s meaning; their speed threshold remains unverified.

Source and coverage
- Monitor
- Radar monitor 305290, Main Street.
- Reporting window
- March 31–April 24, 2026: dates with recorded traffic in the export. First and last days are partial. These boundaries do not establish physical installation or removal dates.
- Source resolution
- 30-minute intervals. Hourly and daily views aggregate those intervals. Times are shown as recorded; no timezone conversion is applied.
- Counts
- Recorded vehicle passages, including repeat trips. The export does not identify unique drivers.
Calculation notes
- Device flags
- The CSV’s #violators field, preserved without assigning it a speed threshold. Flagged rate = flags ÷ recorded passages. The setting and field definition need confirmation before labeling these counts “above 35 mph.”
- Unflagged passages
- Total passages minus device flags. This is not a verified speed-limit compliance count. Percentages are rounded, normally to one decimal place.
- Mean and peak
- Mean = export’s sum of average speeds ÷ passage count. Peak = the largest recorded interval maximum. Neither is a percentile speed.
- Time groups
- Daytime: 06:00–21:59. Nighttime: 22:00–05:59. Weekends: Saturday and Sunday.
Data check and interpretation limits
The 26 inconsistent intervals contain 47 flags. For example, March 31 at 14:30 records 16 passages, 1 flag and a 34 mph peak. No flags were deleted or reassigned. Download the interval audit.
There is no before-and-after comparison or control location. This dataset cannot establish that the sign reduced speeding or explain why speeds differ. It does not measure crashes, near misses or congestion, and does not determine overall road safety. Individual speed readings have not been independently validated by this report.
