TRACC 2.0 Product Tip, Week 6 – Maximum Number of Interchanges
Sad to say this will be the final of our tips and tricks for TRACC’s newest features. The focus for this week is learning how to limit the number of interchanges that can be done in a single journey.
An interchange is when someone moves from one mode of transport to another for example: from house walking to bus, one, from bus to train station, two, off the train and walk to destination, 3.
So why would we want to limit the number of interchanges? Sure, a journey CAN be done, but is it practical and sensible for someone to realistically complete? Are you asking someone to get on three different buses and walk in between just to get to a supermarket?
How to do this?
Make sure to load the layers needed for a Public Transport OD Calculation. These are; Public Transport Network, Road Network, Origin and Destination.
Once the layers you want to use are locked and loaded, begin to setup a Public Transport OD Calculation as you would normally, though hold off going any further when you get to the Parameters page.
You will see that there is an additional parameter named ‘Max Number of Interchanges’, select this option to activate and enter the maximum number of interchanges you wish for a journey to do.
The results returned will only be for journeys that have no more interchanges than the maximum number specified during setup by the user, whilst of course adhering to other parameters placed.
Producing an enhanced output with this calculation will allow you to view the number of interchanges done for each journey.
Here is an example of a Before and After Enhanced Output Report…
If you would like to see a more in-depth breakdown of a journey after limiting the number of interchanges that take place, generating OD path reports is the way forward.
Limiting the number of interchanges can then be really useful to run comparison reports to see how a journey with unlimited interchanges might be affected when there is a limit put on this. See below for an example of the kind of change that can occur if an interchange limit is applied.
Alas, this is our last Product Tip but if you missed any previous ones or want a quick refresher, see below:
Whilst this may be the last of our Product Tips, we are hosting an Ask Me Anything webinar on 1st September 2021 which you can sign up to here. This is a great opportunity for those who may have some questions about the new features and learn a little more about the theme changes that come with TRACC 2.0.
