Traffic Calming Device Inspection Logger

Field guide: Traffic Calming Device Inspection Logger

Traffic-calming devices are geometry doing enforcement's job — and geometry erodes: asphalt humps flatten under bus axles until the 85th-percentile speed quietly climbs back, rubber cushions shed segments leaving anchor bolts proud of the pavement (a tire-killer and a liability letter), and the chevron markings that make a raised table visible at night wear precisely because the device works. This logger audits the calming network as infrastructure with a performance spec, not street furniture.

The bypass findings matter most diagnostically: rutted verges beside a cushion or gutter-running around a hump mean drivers found the escape route, and the fix is design (edge bollards, full-width devices), not paint refreshes. Emergency-response complaints get their own flag because they reopen the design conversation formally — response-time disputes are how calming programs get dismantled, and dated logs of which device, which complaint, which mitigation keep that conversation factual.

Field tips

• Drive each device at the posted advisory speed during the audit — a hump you don't feel is a hump that stopped working.
• Audit at night once a year: marking-wear findings rank themselves by headlight, and 'invisible at night' is a strike claim waiting.
• Photograph verge rutting early; it's the cheapest moment to add edge treatment before the bypass path becomes established.
