Ravi Kaberwal Graduate Transport EngineerUsing 3D Pedestrian Microsimulation to Demonstrate Good Design PrinciplesJuly 2016

Design models have been used for many years by designers and engineers as a tool to understand the practical implications of using a design, including its:strengths weaknessesopportunities for improvementFrom a pedestrian analysis perspective, depending on the scale of the project, we use both static and dynamic models extensively.

3Static models (both visual and mathematical) can be used to guide minimum requirements.

Whether it be determining how wide a footpath needs to be, or the number of escalators required.Pedestrian perspective

2D dynamic models, in addition to informing design requirements can be used to identify:conflict zonesbottlenecksother design issues which would otherwise may not have been identified.

3D simulation provides an opportunity to immerse ourselves and others within our designs.5

6 On projects, particularly large scale infrastructure projects, you engage with a wide variety of:peers from other disciplinesclientsstakeholdersEach with numerous (and sometimes differing) perspectives and opinions. 3D animations can be used as a communication tool to visually explain why certain design element is appropriate, or simply doesnt work.

For any design there have always been those elementary principles, which we as specialists tend to adopt on the understanding that they represent good design.

When a design is reviewed, unique or different, design solutions are ironically quite often easier to explain as we would have a reason to diverge from what we understand to be good design.What happens when a client, stakeholder or a peer questions these good design principles? How can we explain why we used one design over another?

More of an even split. On face value this appears to be a good design, but in reality it probably wont be even

This lends itself to the next concept. Proximity.

34 For these 4 simple concepts Ive showed you their strengths and weaknesses in around 10 minutes. How much quicker and easier could it make walking through even more difficult concepts withPeers from other disciplinesClientsStakeholders?3D pedestrian animations arent just limited to the this example, but can be applied to any environment or project to immerse people within your design.
