Marker lines are simplified and, for smaller roads, may be a simple straight line from the start of the measured section to its end rather than an accurate representation of the road. Please refer to the underlying map for the precise route of the road.
| Year | Average Delay | Delay Index (all roads) | Delay Index (non-trunk roads) |
|---|---|---|---|
| 2023 | 0.0 | 1 | 2 |
| 2022 | 0.0 | 2 | 3 |
| 2021 | 0.0 | 1 | 2 |
| 2020 | 0.0 | 3 | 3 |
| 2019 | 0.0 | 3 | 3 |
The delay index is shown for all roads as well as non-trunk roads. Congestion is typically higher on non-trunk roads than it is on trunk roads, so it's usually more useful to compare values like for like.
The delay index in the table relates to the year in that row. So it's possible for the delay index to go up (get worse than other roads) even when the actual delay has gone down, and vice versa. It depends on how much delays have changed on other roads as well as this one.
