Re: [sumo-user] Macroscopic traffic flow - is it possible with SUMO?

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

Hello,

MAROUTER uses a hard-coded capacity-constraint function based on speed limit, lane number and edge priority to compute traveltimes and flows based on density.

For details, see

src/marouter/ROMAAssignments::capacityConstraintFunction

src/marouter/ROMAAssignments::getCapacity

MAROUTER reads OD matrices and creates route files. These route files contain route distributions between traffic assignment zones. Each route in the distribution is a fully specified list of network edges.

For usage examples, see https://github.com/eclipse/sumo/tree/master/tests/marouter

regards,

Jakob

Hi. I need to use macroscopic traffic flow model - it is necessary for some mathematical calculations. I have read in FAQ that sumo supports "macroscopic traffic assignment" using MAROUTER. I feel like this doesn't mean that I have full macroscopic model with elements like density, flow based on density etc. Am I right? After proceeding everything from documentation with MAROUTER I get traffic assignment zones, is this the point of  "macroscopic traffic assignment" support?
