TARU 3/71: Traffic Signal System for High-Speed Roads

A report describes the development of a traffic signal system for high-speed roads to reduce driver error risk. The system uses conventional vehicle loop-detectors and a timing control device based on Crawford's experimental results on driver judgement. The report is published by the NSW Government and last updated on 2026-06-26.

Use Cases

• Designing traffic signal timing based on vehicle speed and dilemma zone concepts described in the report.
• Evaluating driver error reduction strategies for high-speed approaches to intersections.
• Researching the application of Crawford's experimental results on driver judgement to real-world traffic control systems.

Strengths

• The report is based on Crawford's experimental results on driver judgement and error during the amber period.
• The system design is specifically aimed at reducing the risk of driver error on high-speed roads.
• The report is published by the NSW Government, suggesting an authoritative origin.

Limitations

• The primary data format is a PDF report; the availability of underlying structured data is unknown.
• Row count and column-level documentation are absent; field semantics must be inferred after download.
• Freshness should be verified as the last update date is 2026-06-26.
