Enhancing corridor characteristics and impact score

Introducing a data-driven “Impact Score” that quantifies the likely disruption of any proposed worksite by combining multiple road and traffic metrics.

Problems to overcome:

Without objective metrics, assessing and comparing worksite disruptions relies on subjective judgment and disparate data, hindering consistent prioritization.

• Assessing potential disruption relies on subjective judgment and disparate data sources.

• No consistent way to prioritise or compare works based on network impact.

• Limited ability to set thresholds for when additional review or public communication is required.|

Benefits & outcomes sought:

A standardized, composite Impact Score will enable data-driven triage, consistent prioritization, and targeted mitigation for the most disruptive works.

• Composite Impact Score: Automatically calculated from factors such as road hierarchy, traffic volume versus capacity, predicted queue lengths, network criticality, timing, and alternative routes.

• Integrated with workflows: Score drives conditional routing in CAR/TMP workflows, shapes notification rules, and feeds into clash visualisation.

• Prioritisation & triage: Thresholds trigger additional scrutiny or consultation-works above a defined score require full multi-party review, public notices, or mandatory mitigation plans.

• Resource optimisation: Focuses Corridor Managers and Traffic Operations on the most disruptive works first, reducing network risk and aligning with Auditor-General performance reporting calls.
