Re: [sumo-user] Insert Randomness on route file

[Jakob Erdmann]

Hello,
1) Thank for reporting this issue which is now being tracked at
https://github.com/eclipse/sumo/issues/4076
The warning, which is invalid, was intended as a fail-safe when loading
unsorted route files incrementally.
As a work-around you can load your route file all at once by adding it to
the list of additional files (this disables the check for sorted
departures):
sumo --additional-files yourVehicles.rou.xml
This way, the option --random-depart-offset should work as expected

2) set --random-depart-offset, set vehicle (or flow) attribute
departPos="random". Then call sumo with different values of --seed or add
option --random (which uses a random seed)
See http://sumo.dlr.de/wiki/Simulation/Randomness
Another important aspect of stochastic simulations are speed distributions:
http://sumo.dlr.de/wiki/Definition_of_Vehicles,_Vehicle_Types,_and_Routes#Speed_Distributions

regards,
Jakob

[sumo-user] NetConvert Pedestrian Traffic Light Sequencing

[Alex Sawczuk via sumo-user]

Hi there,

I see under netconvert we have many options to set various timings. However
we do not have control over how long a pedestrian crossing should be green,
and perhaps more importantly red after that green period.

At present we have issues that auto generated traffic light sequences only
have 5 seconds of green followed by 5 seconds of all red before the traffic
is allowed to continue and this is not enough time for pedestrians to cross
the road.

When I set --tls.allred.time this just results in a longer red sequence
before the pedestrians start crossing.

Perhaps it's just a bug and allred should be applied after the pedestrian
green sequencing, I'm not sure what the intended behaviour is?

[sumo-user] Insert Randomness on route file

[Thanos Tasakos]

Hello all,

   1. if u have a given rou.xml file is it possible to create many
   different perturbed versions of it (i want to add stochasticity at each
   run). One option that i came accross was to use --random-depart-offset
but when i add this tag to my sumocfg file the sumo-gui wouldnt
   run giving a Warning that the departures should be ordered.
   2.  Generally given a .rou file how can i change it(different
   departures, different starting positions)

Kind regards,

Thanos Tasakos

[Surya Soman]

   Thank you Jakob!  The code is working now.

But unfortunately the vehicle speed and position I'm getting at each step
is the ego vehicle's speed and position were I wanted to retrieve the speed
and position of  the vehicles around my ego vehicle.

Could you help me with this. Thanks in advance!

[sumo-user] Questions about manipulating SUMO networks

[sumo]

Hello,

I have two networks that were originally converted from OSM to .net.xml and 
heavily edited in `netedit` afterwards. These networks cover neighbouring areas 
in the city and they share common edges/nodes. I would like to join them into 
one larger network, but manual approach is not feasible, the networks are quite 
large. Before I start to develop something, I wanted to ask if by chance there 
is a tool that would be able to accomplish this (maybe `netconvert` has 
something that I have overlooked?).

If not, my best shot would be to patch `sumolib` to allow easier merge of both 
network graphs (not easy but doable) and then patch `sumolib` again to be able 
to write out a network file (I looked only briefly into the source and I did 
find only a method to read the network, there seems to be no write method 
available). Any thoughts about this approach?

The second question regards adding elevation to an existing .net.xml file. The 
original data in OSM are flat, but I have now a possibility to map 
geo-coordinates to elevation data. I cannot use the original OSM to extend it 
with elevation data due to the fact that the network has been already edited, 
so my approach would be again to use `sumolib`, map the XY coordinates to 
LatLon coordinates using the provided `sumolib` methods, request the elevation 
from the mapping server, update the nodes/edges with elevation data (just 
assigning the elevation to Z axis) and then use the above mentioned patched 
`sumolib` to spit out a new network. Does it sound reasonable or am I missing 
something?

Thanks a lot for comments.

Jan
