Dear Charitha,
activitygen cannot be extended easily with additional parameters. You would
have to change the source code available at Github
<https://github.com/eclipse-sumo/sumo/tree/main/src/activitygen> and
compile SUMO yourself. Actually SUMO does not focus on mobility demand
modeling but rather on executing the resulting traffic in a network. In
contrast TAPAS
<https://www.dlr.de/vf/en/desktopdefault.aspx/tabid-12751/22270_read-29381/>
as an example for mobility demand models integrates many sociodemographic
statistics to draw a population from.
Best regards
Mirko

Betreff: [sumo-user] Question about synthetic population and household
level trips

Dear all,
>From the documentation, SUMO parameterizes a synthetic population based on
the following information. Can you advise me on what I should do if I want
to add another parameter that describes the synthetic population? For
example, say I want to add household income as another parameter and make a
condition that says higher-income households are more likely to use cars.
<city> <general inhabitants="1000" households="500" childrenAgeLimit="18"
retirementAgeLimit="65" carRate="0.58" unemploymentRate="0.05"
footDistanceLimit="350" incomingTraffic="200" outgoingTraffic="50" /> </
city>
Secondly, is it correct to say that SUMO models mobility demand at the
individual level and not at the household level? If that is the case, do
you have a suggestion on how we can aggregate the mobility demand at the
household level, taking into account some known statistics about household
size and composition?
Regards
Charitha
