How to read the map
Every mark is a pothole someone reported. The more reports it gets, the more rings fill the mark. Quiet months take rings back, and a year of silence fades the mark to history.
- One ring reported
- Two rings two reports
- Three rings three reports
- Four rings four reports or more
- History gone quiet — possibly fixed
Every report adds a ring, up to 4. 90 days with no new report take one away, never below one. After 365 days with nothing new, the mark fades to history.
Silence also lightens the mark: full strength while fresh, then 72% from 90 days, 50% from 270 days, and 35% once it is history at 365.
Rings are agreement, not how bad the hole is. A pothole many reports agree on can be small; a single ring can be deep.
Every state, in one place
Rings are reports agreeing, minus one for every 90 quiet days — never how bad the hole is. Up to 4; never below one. Read across for more reports, down for more silence: the mark loses rings and goes lighter.
We try to tell the story of a pothole over time, so you can see how recently someone reported it and whether there is consensus. Together, this is how we can plot potholes.
The more reports, the more confidence we get. Below is a table that shows the states of our possible potholes. You can also see this by clicking on an individual report.
| Days since the last report ↓ | Reports agreeing → | |||
|---|---|---|---|---|
| 1 report | 2 reports | 3 reports | 4+ reports | |
| ≤30 days · fresh | ||||
| 90+ days | ||||
| 270+ days | ||||
| 365+ history | ||||
- A new report both adds a ring and resets the clock, so a faded mark jumps straight back up.
- History (365+ quiet days, or 10 riders went over it without reporting) is kept, faded — possibly fixed — and the History switch hides it.
- Yours: the holes you just added wear a light casing and a slow pulse so you can find them.
