Road Safety Audit and Concept Design for Jenkins Terrace Intersection, Naracoorte

Client

Department for Infrastructure and Transport (DIT)

Location

Jenkins Terrace and Aitchison Avenue Intersection, Naracoorte, South Australia

Sector

Road Safety and Infrastructure Design

The Riddoch Highway (A66) is a vital transport corridor connecting Dukes Highway to Port MacDonnell, serving as a key route for freight and regional travel. Within the Naracoorte township, the intersection of Jenkins Terrace and Aitchison Avenue required critical safety and functionality improvements to enhance traffic flow and reduce risks for road users. The Department for Infrastructure and Transport (DIT) engaged BE Engineering Solutions (BEES) to perform an existing conditions day and night Road Safety Audit (RSA) and to deliver concept designs with actionable recommendations for improving the intersection’s safety and efficiency.

The Challenge

The intersection presented several challenges that required expert analysis and innovative solutions:

  • The intersection presented several challenges that required expert analysis and innovative solutions:
  • High traffic volumes from both local and highway users created safety risks and congestion during peak times.
  • The intersection’s design needed updates to meet modern safety standards and accommodate all road users, including heavy vehicles, passenger cars, cyclists, and pedestrians.
  • Conducting a thorough safety assessment that considered differing conditions during day and night, including visibility and lighting.
  • Developing practical and cost-effective recommendations / concepts that could be implemented without significant disruption to the local community and regional traffic.

Our Approach

BE Engineering Solutions utilised a systematic and data-driven methodology to address the intersection’s challenges:

  • Conducted a detailed day and night audit of the intersection to assess current traffic patterns, visibility, lighting conditions, and road user behaviour.
  • Identified hazards and inefficiencies, including insufficient signage, lane markings, and pedestrian facilities.
  • Assessed the suitability of the intersection’s layout for handling both local and through traffic, particularly heavy vehicles using the Riddoch Highway.
  • Analysed traffic flow and collision history to identify key areas of risk and prioritize solutions.
  • Evaluated the intersection’s compliance with Australian road safety standards.
  • Delivered tailored concept designs with practical recommendations to enhance safety and efficiency.
  • Proposed solutions included improved lane geometry, upgraded signage and lighting, and safer pedestrian crossing points.
  • Suggested traffic-calming measures to reduce vehicle speeds and improve safety for vulnerable road users.
  • Provided a detailed report to DIT, including audit findings and prioritised recommendations for immediate and long-term safety improvements.
  • Collaborated closely with the client to ensure the proposed designs aligned with broader regional transport goals and budget considerations.

Outcome

The project delivered by BE Engineering Solutions resulted in a comprehensive understanding of the intersection’s challenges and practical solutions to improve safety and efficiency.

Key outcomes included:

  • Enhanced road safety through actionable recommendations for design improvements, reducing risks for all road users.
  • Improved traffic flow with proposed upgrades to intersection geometry and traffic control measures.
  • A clear, well-structured concept design that supported DIT’s planning for future upgrades, aligning with broader transport network objectives.
  • Recommendations that balanced cost-effectiveness with the need for impactful and sustainable safety improvements.
