What is modelling and why do
we need it?

• A simplified representation of a part of the real world
• Our models emulate the movement of goods vehicles, taxis, buses, cyclists, cars and pedestrians through the network
• Using our knowledge of the network, we replicate real-life conditions in our models to test future scenarios and predict outcomes
What is a Model?

Why do we need models?
We need models to... • Perform analysis:
• Without impacts on street • Before any work is done • To plan for contingency situations
• Ensure that we balance the needs of all road users
• Help us to predict the impact of schemes in the future
• Enable us to clearly communicate • Maximise the benefits of a scheme

What is Operational Modelling? • Operational modelling focuses on analysing the predicted impact
of the vast number of large and small changes taking place across London, and helps to ensure that the correct operational decisions are taken.
• It provides a balanced and impartial, information based viewpoint of schemes.

• TfL Modellers attend and present at industry conferences such as Modelling World and numerous software user group conferences.
• Version 4 of Traffic Modelling Guidelines currently in development.
• Road Space Management’s Modelling best practice guidelines are used as a key reference by industry leaders:
• Traffic Modelling Guidelines
• Model Auditing Process (MAP)
TfL are Industry Leaders in Traffic/Transport Modelling
In a survey of industry leading consultants, 94% said that
TfL Modelling support documents influenced the
way they worked.

3D Visualisation
![Page 9: A Step Change in Modelling & Visualisation at Transport ... · TfL are Industry Leaders in Traffic/Transport Modelling In a survey of industry leading consultants, 94% said that TfL](https://reader033.vdocuments.site/reader033/viewer/2022060602/60570cd53f36a8255a774c61/html5/thumbnails/9.jpg)
9 3D Visualisation Modelling outputs can be converted to 3D animations: • Useful for design
– Cheaper than on-street trials • Powerful tool for stakeholder engagement
– Quicker decision-making
• Provides realism – helps people to coordinate what they are seeing with what they know about the area.

VR allows us to fully immerse our customers into our newly proposed schemes so they can get a realistic insight into how we plan to improve the everyday lives of Londoners by easing congestion, re-designing urban realms and improving air quality.
Mixed Reality (MR) technology like HoloLens could provide TfL a unique way to plan and design new schemes in real-time in a far more collaborative way than traditional methods currently allow us to.
