4. Transport modelling
Buckinghamshire County Council has developed a set of transport models to be used as part of a Transport Assessment (TA). They are also used as the common forecasting tool for all transport processes.
These models, in simplistic form, aim to predict what will happen if we change something to the road or transport network in the county.
These models cover Aylesbury Vale, Buckingham, High Wycombe, and Buckinghamshire Countywide.
The need for the models
Due to a growing population, thousands more houses and employment sites will be built over the coming decades. This will create extra pressure to existing roads and increase the need for construction of new roads or other transport infrastructure.
The Buckinghamshire Local Transport Models assists in planning sustainable locations. The models help us understand the impacts of proposed housing growth and infrastructure schemes. They do this through analysis of:
- traffic flows on particular highway links
- link time to determine impacts of congestion
- routing information
- trips for any given year / scenario
- mode, destination and time of day choice
How they work
Data is fed into the model, this informs us what will happen. For example, how traffic patterns change if we:
- built a new bypass
- built a new housing / employment site
- make changes to highway infrastructure
