Each approach is coloured by how traffic is moving at the stop line. The figures alongside are the time to get through the junction on that approach right now, against the time it takes with no traffic.

Journey time
Measured every 15 minutes in the peaks (every 5 minutes on the two A21 exit slips), half-hourly during the day and two-hourly overnight. The shaded bands are the weekday peak windows the monitor samples most closely (06:30–10:00 and 15:00–19:30).
Average delay by hour and weekday
Where the colour spreads sideways, the peak is widening: the junction is busy for longer, not just busier at the top. That spread is the earliest sign of a junction running out of capacity.

Set the two periods and press Compare. The monitor measures journey times, delays and queues rather than counting vehicles, so the changes shown are in how long the journey takes and how often it is queuing — which is what residents experience, and what a junction assessment turns on.
| Measure (weekdays) | Now | Then | Change |

Percentages are relative changes in the measure named on each row. Delays are averaged over every weekday reading in the peak windows (06:30–10:00 and 15:00–19:30); “queuing minutes” count time in the red per weekday; the planning time index is the 95th-percentile journey time divided by free-flow. Heat-map cells are coloured on the same green–amber–red scale as elsewhere on this page; the change map shows where the hour has got worse (red) or better (green) by more than about 5% of the free-flow time. Weekend readings appear in the heat maps but not in the figures.
Last 28 days, village → Tunbridge Wells
Every day is summarised and kept permanently. This table is what goes into the monthly report and, in time, the before-and-after comparison. Delays are coloured on the same scale as the live board: green when the journey averages under 1¼× its free-flow time, amber up to 1¾×, red beyond that or when the delay tops five minutes. Plan for is the time to allow in that peak — the 95th-percentile journey time, which is closer to what a driver in the queue experiences than the average (see Reading the numbers below).
| Date | AM peak avg delay | AM worst | AM plan for | PM peak avg delay | PM worst | PM plan for | Time of worst | Queuing (min) | Longest queue | Queue present (min) | Planning time index |

Queues on the A21 carriageway, last 28 days
Every time the exit queue extends back past the end of the slip road onto the A21 itself, the record logs an episode: when it started, when it cleared, how long it lasted and how far back it reached. These are the periods when through traffic meets stationary vehicles on the main carriageway.
| Date | Exit | From | Until | Duration | Longest queue | Average queue | Worst delay |

Tell us how long it really took
The monitor's readings are estimates from average speeds (see Reading the numbers). Timed real journeys are the check on them. If you drove one of the measured journeys, tell us when you set off and how long it took, and we will set it beside what the monitor said at that moment. Nothing but an initial is shown; no email is asked for.

The journeys and points behind the figures
Every figure on this page comes from one of the measurements below. Each journey is asked of the routing service from a fixed start to a fixed finish; each point is a spot on the road where the live speed is read. Hover or tap a row to pick it out on the map, or open it in Google Maps to see the exact spot.
