Betreff: [sumo-dev] Give me some advice for making multimodal simulation

Dear SUMO developer member
This is shu.
I want to create intermodal situation in SUMO environment.
Does anyone can advise me how to make multimodal situation through SUMO
tool?
First, I’d like to send you my current situation in movie.
<https://drive.google.com/file/d/1QkEGWbWRTMu78BmgZ5JXk0nGzRtRb1Sl/view?usp=sharing>
In this congested situation, agent should move to BUS, but nobody uses it.
I’m not sure this problem.
Here is rou.xml data example below.
--From here--
<!-- VTypes -->
<vType id="BUS" vClass="bus"/>
<!-- Vehicles, persons and containers (sorted by depart) -->
<flow id="busflow1" type="BUS" begin="39600" line="line1" from="E51"
to="E51" end="86400.00" period="600.00">
<stop busStop="bs_2" until="10.00"/>
<stop busStop="bs_4" until="45.00"/>
<stop busStop="bs_3" until="60.00"/>
<stop busStop="bs_1" until="510.00"/>
<stop busStop="bs_2" until="1050.00"/>
</flow>
<personFlow id="t_10789" begin="43199.00" end="43499" probability="0.02">
<personTrip from="-671947195#0" to="-75946082#3" modes="public car"/>
</personFlow>
<personFlow id="t_10790" begin="43201.00" end="43501" probability="0.02">
<personTrip from="-76951149#4" to="-585820947#0" modes="public car"/>
</personFlow>
<personFlow id="t_10791" begin="43201.00" end="43501" probability="0.02">
<personTrip from="-120305146#0" to="-120305146#0" modes="public car"/>
</personFlow>
!--・・・lots personFlow command after above example--
I’d like to explain what I want to know and build situation.
Intermodal(multi-modal) situation is what I want to build.
It means below,
Every agents( personFlow command like above) can judge their best routes
through <modes = “public car”> command to select “walk, car, or bus”
between OD(begin ~ end) trip.
-Car to parkingArea to BUS
-Walking to BUS and move to their destination by foot or car.
BUS route is concretely defined.
Car and walk are based on OD data.
It is preferable that a modal shift occurs, especially under traffic jam
conditions.
However, as the movie I sent you, nobody shift to ride on the BUS from
their original vehicle even on the congested situation.
Therefore, I want to know, which point I should care more about.
For example, like command side, net.xml file side…etc. I’m not sure how to
solve this problem.
Could you advise me some tips?
In addition, I want to know the SUMO algorithm of agents routes judgement
methods.
Is it basically to say, the default mode is based on below?
“Travel-time values for routing
By default, the route with the least travel time is chosen. The travel time
depends on the current routing mode (configurable via
traci.vehicle.setRoutingMode) or via the explicit routingMode argument to
traci.simulation.findRoute.”

Hopefully, this question will solve as soon as possible.
Thank you for your cooperation.
Best regards,
Shu
