Stage 22.0.1 paired freight evidence and Stage 23A.4.0 operating-speed pressure and reliability evidence
Frozen speed reference: VTA_STAGE23A4_P85_20251101_20260521
CG-01
What overnight hour has the lowest measured operating pressure across the governed Tier A network?
Answer: 4:00 am-5:00 am
Across all 269 Tier A headings, this hour has the lowest mean pressure index at 2.43, mean speed at 98.1% of reference and mean below-90% occurrence of 3.6%.
Operator action: Test flexible departures in this window, then use the heading lookup because the best hour varies by location.
Boundary: This is a network-wide overnight average, not a guarantee for every route or a complete journey-time result.
CG-02
Which monitored network heading has the greatest recurring truck-speed pressure?
Answer: Tullamarine FWY Inbound - Before Mickleham Rd (SB)
Pressure index 56.03; below 90% of its own hourly reference during 75.5% of eligible hours; sustained pressure on 76.9% of eligible nights.
Operator action: Prioritise departure-time review, quoting review and route-specific operational investigation for work exposed to this heading.
Boundary: The pressure index is relative point-speed pressure, not journey delay or a dollar loss.
CG-03
Which monitored network heading is least reliable from night to night?
Answer: Tullamarine FWY Outbound - After Mickleham Rd Exit (NB)
Its nightly P90-P10 observed-to-reference spread is 32.6 percentage points, with pressure index 41.65.
Operator action: Use a larger evidence-based contingency class and avoid promising the same tight arrival window used on stable lanes.
Boundary: The evidence supports a relative contingency class, not an exact number of buffer minutes.
CG-04
Which lanes should receive the first route-pricing risk review?
Answer: Tullamarine FWY Inbound - Before Mickleham Rd (SB) — SEVERE REVIEW
The screening class combines governed pressure, night-to-night spread, sustained pressure and severe below-reference occurrence. The page lists the leading 20 candidates for commercial review.
Operator action: Review quoted allowances, fixed time windows, waiting clauses and corridor-risk terms before changing actual prices.
Boundary: This is a risk-screening class, not a recommended tariff or proof that an existing contract is unprofitable.
CG-05
Which lanes justify the largest schedule-contingency class?
Answer: Tullamarine FWY Outbound - After Mickleham Rd Exit (NB) — LARGEST CONTINGENCY CLASS
The class is driven by nightly reliability spread, sustained-pressure frequency and longest pressured runs.
Operator action: Apply larger contingencies only to genuinely variable lanes and reduce unnecessary padding on stable lanes.
Boundary: No minute value is assigned because journey distance, customer time and operator practices are not in the dataset.
CG-06
Which monitored headings provide a lower-risk operating benchmark?
Answer: M80 - WRR East of Mahoneys Rd GB
The leading lower-risk benchmark has pressure index 0.00, nightly reliability spread 1.4 points and observed speed at 98.7% of reference.
Operator action: Use low-risk headings as operational benchmarks and compare candidate times or corridors before dispatch.
Boundary: A low-risk monitored heading is not automatically a valid alternative route; route connectivity and restrictions must be checked separately.
CG-07
Where is the signal for fuel and vehicle-wear exposure strongest?
Answer: WGB_OUTBOUND_W for severe-hour exposure
WGB_OUTBOUND_W is below 70% of reference during 30.4% of eligible hours. Tullamarine FWY Inbound - Before Mickleham Rd (SB) has the largest long-period observed-reference speed deficit at 16.5 km/h.
Operator action: Prioritise these locations for departure-time changes, telematics review and operator-specific fuel analysis.
Boundary: The current data identifies operating exposure; it does not calculate litres, maintenance dollars or emissions.
CG-08
Where does directional imbalance suggest the strongest empty-return or backload risk signal?
Answer: M1 Monash-Princes Freeway East - Mulgrave - M1 Outbound - CH 26380 / M1 Inbound - CH 26380
Median directional imbalance is 30.3%, with 65.1% in the dominant westbound direction.
Operator action: Target return-load sales and contract pairing toward the weaker direction, or ensure the dominant-direction job price covers likely empty running.
Boundary: Directional sensor imbalance is an opportunity signal; it does not prove that a backload is available.
CG-09
Where does balanced high-volume activity support staging, shuttle or depot investigation?
Answer: M1 Monash-Princes Freeway East - Mount Waverley - M1 Outbound - CH 17390 / M1 Inbound - CH 17390
It averages 2,170.2 combined truck passings per normalised eight-hour night, 100.0% balanced nights and median imbalance of 2.5%. The highest combined-volume paired asset overall is West Gate Bridge - Corridor_Only - WGB_INBOUND_E / WGB_OUTBOUND_W at 2,202.1.
Operator action: Use these freight-flow signals to shortlist areas for shuttle, trailer-staging, cross-dock or depot investigation.
Boundary: A siting decision still requires land cost, customer locations, access restrictions, zoning and complete route economics.
CG-10
Which locations need the strongest disruption and recovery playbooks?
Answer: Tullamarine FWY Outbound - After Mickleham Rd Exit (NB)
The leading reliability-risk heading has a 32.6-point nightly spread. West Gate Bridge inbound and outbound are also among the top three reliability-risk headings and both have recorded worst-night pressure runs spanning all eight overnight hours.
Operator action: Pre-plan customer notifications, departure holds and approved alternatives for jobs dependent on these locations.
Boundary: Worst-night and reliability evidence identifies fragility; it does not identify the external cause of each episode.
Commercial interpretation boundary
The findings support dispatch, quoting, customer-window negotiation, contingency planning and opportunity screening. They do not calculate exact profits, fuel litres, buffer minutes, journey-time savings or truck-hours. Exact commercial outcomes require operator-specific cost and revenue data.
