Step-by-Step Guide to Conducting a Swept Path Analysis

Have you ever wondered how some routes are designated for larger vehicles during construction or complex ramps are designed? The answer lies in swept path analyses – an important tool used by engineers, architects, and planners to assess the movement of vehicles through road networks, intersections, carparks and access points.

Here we’ll breakdown everything you need to know about swept path analyses, from its importance to the step-by-step process of conducting one.

What is Swept Path Analysis?

Swept path analyses is a computer assisted simulation tool used to determine the space required for a vehicle to manoeuvre through a given area. This analysis involves simulating the trajectory of a vehicle’s outermost points as it navigates turns, corners, or other obstacles within a defined area. By examining the swept path, engineers can determine whether a vehicle can practically manoeuvre through an area without impacting critical road infrastructure and other obstacles.

The process typically involves using software to create visual representations of vehicle paths based on their dimensions and turning radii. This is especially important in urban planning and road design, where tight corners or limited space can pose significant challenges for larger or niche vehicles. Swept path analyses ensures that an infrastructure project functionally accommodates vehicles likely to be utilised/generated by the development, and minimises the risks of collisions and property damage.

The analysis is especially useful for:

·       Roadway and intersection design

·       Carparks and loading docks

·       Driveways and access points

·       Industrial and commercial developments

A well-conducted swept path analysis ensures:

·       Compliance with Australian road standards

·       Improved traffic flow and safety

·       Efficient use of available space

·       Prevention of costly modifications post-construction

Many Australian cities, such as Melbourne and Sydney, require swept path analysis services for planning permits and development approvals.

Step-by-Step Guide to Conducting a Swept Path Analysis

Conducting swept path analyses requires careful attention to detail and adherence to specific steps.

Define the Scope of Analysis

Start by identifying the purpose of your analysis. Are you assessing vehicle access for a new development, or evaluating road safety? Clear objectives will guide your approach. Consider:

1.         The type of vehicles that will use the space;

2.         The purpose of the analysis (compliance with regulations, optimising traffic flow, optimising the trafficable area); and

3.         Site constraints and limitations.

Gather Necessary Data

Collect all relevant information required for the analysis, including:

·       Site plans and layouts;

·       Vehicle dimensions and specifications;

·       Turning radius and manoeuvrability data; and

·       Local government planning regulations.

In Melbourne and Sydney, councils may provide specific guidelines for conducting a swept path analysis to meet compliance requirements.

Choose the Right Software

Choose appropriate software that supports swept path analyses, such as AutoTURN or AutoTrack for AutoCAD – commonly used by engineers for integrating with CAD designs.

Input Vehicle Parameters

Input the vehicle dimensions and turning specifications into the software and create a representation of its path as it manoeuvres through intersections, carparks, or accessways. Ensure that the selected vehicles reflect real-world usage scenarios, such as non-standard semi-trailers for specific commercial uses or developments that may require specialised waste or loading vehicles.

Simulate Vehicle Movements

Using the software, simulate vehicle movements through the designated space. This will help visualise vehicle turning paths, spatial requirements and critical design points.

Analyse Results and Identify Issues

Review the generated paths for potential conflicts with obstructions such as curbs, columns, walls and existing infrastructure. Look for any areas where clearance may be insufficient.

Make Adjustments

If any issues are identified during your analysis, consider possible design modifications like widening roads or altering traffic flow patterns to enhance safety and accessibility.

Document Findings

For development approvals, provide detailed reports outlining:

·       Analysis methodology and findings;

·       Compliance with Australian standards (such as Austroads, AS2890.1 for parking design); and

·       Recommendations for design improvements.
