Re: [sumo-user] How to map match GPS dataset to nearby edge with SUMO

[Jakob Erdmann]

TraCI does not support GPX files directly. You will still need to write a
program that loads these files and sends the correct TraCI-commands.

 Hello,
 If the spatial error in your GPS data is low, you can use TraCI to
 perform this mapping
 you can convert lon,lot to edge,pos using traci.simulation.convertRoad(x
 ,y,geo=True)
 However, if the mapping is ambiguous there are more sophisticated
 algorithms to select the most plausible road.

 Jakob

Re: [sumo-user] SUMO question about output representation

[Jakob Erdmann]

When using simulated induction loops (
http://sumo.dlr.de/wiki/Simulation/Output/Induction_Loops_Detectors_(E1))
you can set the attribute splitByType="true" to get type-specific output.

When using edgeData (
http://sumo.dlr.de/wiki/Simulation/Output/Lane-_or_Edge-based_Traffic_Measures)
you can filter for type by setting the vTypes attribute (i.e.
vTypes="bus"). You will then need a separate -definitions for
each type (or list of types) you are interested in.

Jakob

Re: [sumo-user] simulation time

[Jakob Erdmann]

Hello,
the statistics summary cannot be printed to an xml file at the moment. You
could use the --summary-output which outputs information every step and
check the time stamp of the last output value.

[sumo-user] SUMO question about output representation

[Jirayu Tippayagulpairod]

Dear user and developers ,
 I'm student in Thailand who do the project with SUMO
program and I have some question to ask. As I used SUMO , it can simulate
the many type of vehicle in traffic and the
output is in form of enter , left ,density , travel time but it doesn't
show each type of output (For example : I mean that 4 outputs for car and 4
outputs for bus individually) Therefore, I want to know that Can SUMO
simulate the outputs individually for each type of vehicles or it cannot ?

Best regards,

Jirayu Tippayagulpairod

[sumo-user] simulation time

[Thaer Thaher]

Dear,

To simulate all vehicles  no value for --end has been given. The 
(--duration-log.statistics) option will print averages for vehicles trip like 
the simulation time. can we output  these results to an external xml file.

I'm interested in finding the required time to simulate all vehicles for 
different traffic light programs.

Thanks

[sumo-user] Regarding Modelling of Inducion detectors

Hi,

I have created traffic scenario using a OSM web wizard as indicated in the
tutorials and I was wondering if there is any way to model induction
detectors on the lanes ?
