Transit viability*
* Indicative only. Based on effective density and not adjusted for jobs, interchanges, airports, tourism, or other major trip generators.
Uses the higher of residential and daytime activity density for the selected area.
Requires a selected area.
Layers
* Best viewed at national and regional scale.
* Does not include National Rail systems (e.g. Elizabeth Line, Overground, Merseyrail).
⎯ Transit corridors
Transit Corridors
Draw a line to begin
✕
Transit viability thresholds shown as horizontal lines · labels = % of corridor meeting each level
No line drawn yet.
Transit viability uses the higher of residential and daytime density in a moving 1 km window sampled every 250 m along the corridor. This is an indicative planning aid rather than a full transport model.
▩ Radial density

Set a centre and generate a profile.
Each bar is the density within one ring only, not the entire circle inside it. Transit overlay uses the higher of residential and daytime activity density in each ring.

Saved Radial Profiles
Save up to 6 profiles in this session.
Load any saved profile to centre it on the map, or choose up to six matching profiles to compare.
Save Radial Profile
Give this radial profile a name so you can switch back to it during this session.
Comparison uses distinct city lines. Each label shows the total population within the selected radius for the active density mode. Click the coloured dots to change each line colour, drag this window by its header, or save the chart as an image.
Area Statistics

Select an area, then open Area Statistics to see travel behaviour, economic activity, tenure, health, and age structure.
About Centrixia
Why use Centrixia?
For early-stage spatial analysis — understanding locations, testing corridors, and comparing places before committing to detailed modelling.
What does Centrixia show?
A structured view of how a place works — combining density, movement, and demographic patterns into a single, readable interface.
Where does the data come from?
Publicly available UK datasets, primarily from the Office for National Statistics (ONS), alongside OpenStreetMap and related open geographic sources.
How is the data used?
Small-area data (LSOA/MSOA) is aggregated within user-defined geographies and converted into simplified spatial outputs such as radial profiles, corridor analysis, and area statistics.
Built using reliable public datasets, processed for rapid spatial analysis.
