Quantitative, defensible analysis underpinning design decisions and authority submissions.
RSN applies industry-standard tools to provide quantitative, defensible analysis for traffic engineering decisions across New South Wales.
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.
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.
Quantitative analysis gives you defensible data that underpins design decisions and satisfies authority submission requirements, reducing the risk of rejected plans or required redesigns.
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.
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.
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.
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.
Quantitative analysis gives you defensible data that underpins design decisions and satisfies authority submission requirements, reducing the risk of rejected plans or required redesigns.
From SIDRA intersection modelling to swept path assessments, our analysis gives you the defensible data to support your design decisions.
