  • Thread-topic: Route errors using flowrouter.py

Hi all,

 

I have some traffic flow data from counts for a city and I was looking to use either DF Router or flowrouter.py. Looking on other threads I saw that flowrouter.py may be best option as I’m modelling flows within a city area. I am having issues however with the routes.

 

I’ve been using the following command:

 

flowrouter.py -n myosm.net.xml -d MyDetectors.det.xml -f MyNewFlows.csv -o newroutes.xml -e newflows.xml -v passenger -i 60

 

However when I go to run my simulation I get an error “Vehicle '188428824_447312810.qPKW.60.0' is not allowed to depart on any lane of its first edge. Quitting (on error)”

 

When I look at the first edge in this vehicles route it is placed on a pedestrian sidewalk which is why the vehicle can’t depart.

 

None of my detectors are located on sidewalks so I am confused as to why vehicles are being placed on there during their journeys. Is there a way to prevent this from happening?

 

Note 1: I’ve managed to prevent this in DF Router using the disallow edges parameter where I have a list of all edges that are sidewalks but DF Router discards the majority of the detectors so I get isolated traffic flows.

 

Note 2: I’m not sure if I’ve used the –v passenger command correctly. I’ve tried --vclass passenger but then I get “Error! No sinks found.”

 

Could someone provide me with some advice on how to ensure vehicles are only routed on roads that will allow them.

 

Thank you in advance.

 

Kind regards,

 

Barry
