Sounds like that would be fun!
I suspect you won't be able to model the ramp in sumo though. The road network in sumo cannot currently be changed dynamically - it is loaded on simulation start.
lanes can be closed dynamically but I don't believe the elevation can be changed - which is essentially what you are doing with the ramp - changing the elevation of one end.

For the prototype phase, we will follow a simpler model.
However, beyond prototype phase, following factors need to be incorporated into the simulation.
-
The position of the ramp with respect to the ship, under keel clearance (UKC) of the ship, ground clearance of vehicles.
-
A loaded ship will sink lower into water. Empty ship will rise up. Add to this the position if ship depending on low and high tide. All of this in turn will decide the ramp angle and UKC.
-
If the vehicles are too long or have low ground clearances, it can be a problem.
-
The channel leading up to the berthing station limits ship movements in terms of number of shops, size of the ship.
-
The road up to the ferry terminal splits into lanes which have a toll booths. Then then lanes merge again and then split again.

ok, thanks
feels like an approach minimising sumo changes would involve amending train behaviour to carry vehicles and amending the visualisation appropriately. Wouldn't berthing/unberthing/ramp be simply time delays or is the whole purpose to get realistic visualisation?
If not, whether the minimal changes are useful depends on what questions you want the simulation to answer - eg you could model vehicle movement in/out of the harbour by simply having a car park in place of the ship and using flows that begin/end at the car
park. It gets much more challenging if you want to model marshalling of vehicles though.

One ferry can have around 300 vehicles which will be a mix of cars and heavy vehicles.
Initially we will limit the simulation to 2-3 arrivals and 2-3 departures per day.
The maritime extent of the simulation will be limited to 2 Kilometers or about 1 Nautical mile.
We will need to simulate the berthing unberthing procedure and the ramp movement.

Do you have volumetrics that you might share?
Eg ferry capacities, # ship movements/day, sea distances
Also do you expect to model harbour movements/interactions of ferries - docking, reversing etc

Hello sumo-dev and sumo-user.
We are responding to a request for proposal for a project that requires simulation of vehicle traffic through a roro ferry terminal. This involves a mix of marine side simulation with landside simulation. Both land side and marine side simulations will be part
of the single model affecting each other.
We are looking for organizations and individuals interested and experienced in doing custom development work to extend SUMO's existing capabilities.
Please note that we have a deadline (October 17th) for submitting our response for proposal.
We do not expect to finalize all the technical details before October 17th but we do need to start conversations with interested parties to gather information on topics such as features, feasibility, rough design, timeline etc.
Best regards,
Neehar
