Analysis

Quantitative, defensible analysis underpinning design decisions and authority submissions.

Technical Analysis

RSN applies industry-standard tools to provide quantitative, defensible analysis for traffic engineering decisions across New South Wales.

SIDRA Intersection Analysis

RSN uses SIDRA, the industry-standard intersection modelling tool, to assess capacity, queue lengths, delay, degree of saturation, and level of service for roundabouts, signalised intersections, and priority-controlled intersections.

Swept Path Assessments

Our AutoCAD-based swept path analysis, compliant with Austroads design vehicle classifications, verifies that road geometry and site accesses accommodate a design vehicle's full turning path — from small cars to B-double semi-trailers.

Authority Submission Support

Quantitative analysis gives you defensible data that underpins design decisions and satisfies authority submission requirements, reducing the risk of rejected plans or required redesigns.

Frequently Asked Questions

What is SIDRA analysis?

SIDRA is the industry-standard intersection-modelling tool used to assess capacity, queue lengths, delay, degree of saturation, and level of service. RSN uses SIDRA to model roundabouts, signalised intersections, and priority-controlled intersections.

What is a swept path assessment?

A swept path assessment uses AutoCAD-based vehicle turning analysis, compliant with Austroads design vehicle classifications, to verify that road geometry and site accesses accommodate a design vehicle's full turning path — from small cars to B-double semi-trailers.

When is technical analysis needed?

Technical analysis is needed when you must demonstrate compliance to an authority, optimise an intersection design, or verify that a proposed access arrangement is safe. It provides the quantitative, defensible evidence base for design decisions.

Which design vehicles does RSN assess?

RSN matches the appropriate Austroads design vehicle to the road function and traffic task, then assesses turning-path tracking, cornering, site access points, loading areas, and internal circulation.

How does analysis help with authority submissions?

Quantitative analysis gives you defensible data that underpins design decisions and satisfies authority submission requirements, reducing the risk of rejected plans or required redesigns.

Need technical analysis?

From SIDRA intersection modelling to swept path assessments, our analysis gives you the defensible data to support your design decisions.
