Planning application modelling
Local transport modelling
Some planning applications use local transport models to predict and test the potential impacts of a new development on:
- Public transport
- Active travel
- Highway conditions
These models usually deal with individual junctions, crossings or other small parts of the transport network.
You need to carry out local transport modelling if your planning application could affect:
- Traffic signals
- Pedestrian crossing
- Bus journey times
- The capacity and reliability of London's red routes
Your models need to follow our Traffic modelling guidelines and Model Auditing Process (MAP) unless agreed otherwise. Each stage in the audit process can take up to 28 days. Allow enough time to complete the audit before submitting your application.
Strategic transport modelling
We use strategic transport models to understand the potential impacts of our own projects and investments. The models make predictions about:
- Public transport
- Active travel
- Highway impacts
These can be used in the Transport Assessments of large-scale planning applications.
You need to carry out strategic transport modelling if your planning application is above, or around, 1,000 housing units and/or 10,000 square metres of any other land use. There's a fee to use our strategic models.
Our strategic modelling flow chart shows timings and relationships involved when you use our strategic transport models:
Our Future Transport Context reports use our models and other internal data. They provide useful insights on the future transport and travel conditions likely to affect your proposed development.
We're working with Camden Council on the first ever Future Transport Context report for Kentish Town, which will be ready soon.
