Building baseline
Historical baseline: building
Seven completed QA-approved days are enough for an early rolling time-of-day baseline. Weekday-specific normal conditions remain deliberately locked until repeated weekday observations accumulate.
Baseline interpretation: this is an early rolling clock-time comparison, not yet a mature weekday-specific “normal Monday/Tuesday/etc.” model. Missing source periods remain missing; failed or partial days must not be converted to zero.

Freeway Visual Intelligence · v1.10
Melbourne freeway network — live visual status
A photographic live-status view of every freeway represented in the current DTP feed. The cards reuse the same governed live freeway summaries shown elsewhere on this page.

Waiting for current freeway status data…
How to read: “Affected” is the share of current monitored road sections classified Medium or Heavy. “Worst condition” is the most severe DTP condition present among the freeway’s monitored road sections; it does not mean the entire freeway is operating at that condition. Badge numbers always match the selected rank/order and read left-to-right, then top-to-bottom. Current pressure ranks affected road-section share first; worst-condition rank uses condition severity, then affected share and maximum delay. Click a card to filter and locate that freeway on the live map.

What this shows: near-real-time operational performance — travel time, delay, speed, DTP condition and data substitution. What this does not show: vehicle volumes, unique vehicles, tunnel utilisation counts or routing share. Travel-time performance must not be presented as proof of how many vehicles are using the tunnel.

Last 2 hours — verified ~2-minute DTP source observations
Every column represents one distinct DTP source-time period; repeated collector polls are deduplicated.

West Gate operational context — 5-minute periods
Completed QA-PASS periods are governed; current-day closed periods remain provisional until daily QA.
WGT directional summaries sum the two exact DTP features labelled “West Gate Tunnel”. They are WGT-labelled journey values, not tunnel-bore-only travel times. Bridge rows use the exact governed Williamstown Rd ↔ Todd Rd crossing features and should not be interpreted as bridge-deck-only travel times.

A map-first view of where freeway pressure repeatedly returns across completed QA-approved history. Cool colours indicate lower recurring pressure; hot colours identify structurally persistent trouble spots.

Interpretation: this is a structural recurrence map built from observed governed baseline periods, not a live congestion map. Persistence is descriptive and does not by itself establish the cause of congestion. Grey sections are geometry without a map-eligible persistence row for the selected scope.

Blank or missing conditions remain Blank/missing rather than being treated as Light. Speed percentiles use populated feature speed values only.

How to read: affected share is the percentage of observed features in a freeway direction classified Medium or Heavy during the five-minute period. Heavy share can be selected separately. Blank/missing conditions remain missing rather than being treated as Light. Completed QA-PASS periods are governed; current-day closed periods are provisional.

How to read: solid actual lines are completed QA-PASS history; dashed actual segments are current-day provisional five-minute periods. Nominal reference lines are DTP-supplied nominal travel times. A live point is shown only when the live snapshot is fresh. Provisional periods are replaced by governed history after daily compaction and QA. WGT values are WGT-labelled journeys, not tunnel-bore-only travel times; bridge values are crossing features, not bridge-deck-only travel times.

Days in the Top 3 — including #1 days
Stacked bars separate days ranked #1 from additional days ranked #2 or #3, so the total bar length equals Top-3 days.
How to read: chart data use exactly the same ranking-eligible completed days as the historical rankings. Missing source periods remain missing rather than being estimated or forward-filled. BUILDING windows are shown transparently but should not be interpreted as mature long-window evidence until sufficient eligible history has accumulated.

How these rankings are governed
Historical rankings use completed QA-approved Melbourne-local days only. A day must achieve at least 95% governed five-minute source-period coverage and at least 95% retained-period completeness against a fixed 226-road-section governed inventory. Unknown or wholly missing governed feature IDs fail the ranking gate. Missing source periods remain missing rather than being estimated or forward-filled.
Average pressure is the mean five-minute share of condition-bearing monitored road sections classified Medium or Heavy. Heavy time is the share of condition-bearing road-section periods classified Heavy. P95 delay uses DTP's supplied delay field. Rankings are descriptive evidence and do not establish causation.
Methodology
How to read this page
Worst condition means the most severe DTP condition present among the constituent features; it does not mean the entire freeway is operating at that condition. Affected share is the proportion of features currently classified Medium or Heavy.
Displayed delay uses DTP's supplied delay field rather than recalculating it from rounded travel-time values. Missing and Blank values remain missing/Blank. Whole-freeway travel times are not created by summing every feature because DTP route structures can overlap and would risk double-counting segments.
