Re: [sumo-user] Simulation of a taxi dispatcher

[Jakob Erdmann]

Hello,
SUMO brings the basic tools to build this kind of simulation
- networks,
- vehicles
- passengers
- routing
You will have to write a control script that determines the taxi to
dispatch and triggers re-routing of the selected taxi.
The taxi passengers can also be simulated explicitly.
The main client language for controlling a sumo simulation is python.
If you have no programming experience, expect a major learning curve.

regards,
Jakob

[sumo-user] Simulation of a taxi dispatcher

[lior geren]

Hello,

I'm looking into building a simulation of a taxi dispatch algorithm.

My requirements:

   - A network describing a small neighbourhood
   - Several vehicles (taxicabs) with random starting positions in the
   network
   - Passengers (people) generate dispatch request, "I need to get from A
   to B"
   - A logic (algorithm) assigns each dispatch request to an available taxi
   that is nearby
   - The taxi drives to point A, "picks up" the passenger, drives to point
   B, and then becomes free again

What is the best way to approach this? Is there some similar open source
project or plugin I can rely on?

TIA

Re: [sumo-user] Problem: SUMO and SUMO GUI breaking down when starting the sumoconfig file

[Jakob Erdmann]

Hello,
you have stumbled upon a bug:
the magic filename component 'TIME' does not work on windows. You can either
- avoid using TIME in your output-prefix
- or switch to Linux
- or use the latest development version (at least rev. 22002). see
http://sumo.dlr.de/wiki/Downloads#SUMO_-_Latest_Development_Version

There is also an issue with your input files:
- the routeDistributions should be put ahead of the flow definitions in the
.add.xml file (http://sumo.dlr.de/wiki/SUMO#Loading_order_of_input_files)

regards,
Jakob

[sumo-user] Problem: SUMO and SUMO GUI breaking down when starting the sumoconfig file

[Katja Rademacher]

Hi fellow SUMO users,

 

I'm using SUMO for my master thesis project. I have a simple four way
intersection with vehicle flows passing the intersection. I have had a
similar setup working before but had to move the flow descriptions into an
additional file to create them dynamically. Now when I try to start the
configuration file with the SUMO-GUI or start the sumo.exe with the given
sumocfg file both applications stop working and produce the same error both
on the console application sumo.exe and sumo-gui.exe (pictures attached in
archive). 

They both show the message: "The program cannot be executed properly because
of a problem. It is stopped and I will be notified when there is a solution
for the problem. I have the option to close the program or debug it. "

I have no idea what the cause of this problem is. I attached a zip archive
of the folder with the network file, the route file, the additional outputs,
the file with vehicle flows and the sumoconfig file.

Dropbox-Link as the direct attachment doesn't seem to work:
https://www.dropbox.com/s/ffj2hz971v1s96f/sumo_problems.zip?dl=0  

If anyone could help me with my problem showing me my mistake or point me
into a direction at how I could investigate the cause of this, I would be
really thankful.

Thanks for your time.

 

Kind regards,

Katja
