How to use randomTrips.py in SUMO on win8

Question

I'm using randomTrips.py in SUMO to generate random trips on win8. I have a map.net.xml file and try to create a trips.xml file through randomTrips.py. However, the problem occurs and I don't know how to deal with it. The code is as follows:

C:\Program Files (x86)\Eclipse\sumo\tools>randomTrips.py -n map.net.xml -l 200 -e -o map.trips.xml

I don't get the .trips.xml file I want. And the outcome is as follows, it seems that I have missed some properties of the function in my code, but I don't know how to correct it. If anyone knows how to solve the problem, pls give me some valuable suggestions. Thanks. The outcome is :

Usage: randomTrips.py [options]

Options:

-h, --help show this help message and exit

-n NETFILE, --net-file=NETFILE define the net file (mandatory)

-a ADDITIONAL, --additional-files=ADDITIONAL define additional files to be loaded by the rout

-o TRIPFILE, --output-trip-file=TRIPFILE define the output trip filename

-r ROUTEFILE, --route-file=ROUTEFILE generates route file with duarouter

--weights-prefix=WEIGHTSPREFIX loads probabilities for being source, destinatio via-edge from the files named .src.xml, .sink.xml and .via.xml

--weights-output-prefix=WEIGHTS_OUTPREFIX generates weights files for visualisation

--pedestrians create a person file with pedestrian trips inste vehicle trips

--persontrips create a person file with person trips instead o vehicle trips

--persontrip.transfer.car-walk=CARWALKMODE Where are mode changes from car to walking allow (possible values: 'ptStops', 'allJunctions' and combinations)

--persontrip.walkfactor=WALKFACTOR Use FLOAT as a factor on pedestrian maximum spee during intermodal routing

--prefix=TRIPPREFIX prefix for the trip ids

-t TRIPATTRS, --trip-attributes=TRIPATTRS additional trip attributes. When generating pedestrians, attributes for and supported.

--fringe-start-attributes=FRINGEATTRS additional trip attributes when starting on a fr

-b BEGIN, --begin=BEGIN begin time

-e END, --end=END end time (default 3600)

-p PERIOD, --period=PERIOD Generate vehicles with equidistant departure tim period=FLOAT (default 1.0). If option --binomial used, the expected arrival rate is set to 1/peri

-s SEED, --seed=SEED random seed

-l, --length weight edge probability by length

-L, --lanes weight edge probability by number of lanes

--speed-exponent=SPEED_EXPONENT weight edge probability by speed^ (defaul

--fringe-factor=FRINGE_FACTOR multiply weight of fringe edges by (defa

--fringe-threshold=FRINGE_THRESHOLD only consider edges with speed above as edges (default 0)

--allow-fringe Allow departing on edges that leave the network arriving on edges that enter the network (via turnarounds or as 1-edge trips

--allow-fringe.min-length=ALLOW_FRINGE_MIN_LENGTH Allow departing on edges that leave the network arriving on edges that enter the network, if the at least the given length

--min-distance=MIN_DISTANCE require start and end edges for each trip to be least m apart

--max-distance=MAX_DISTANCE require start and end edges for each trip to be most m apart (default 0 which disables a checks)

-i INTERMEDIATE, --intermediate=INTERMEDIATE generates the given number of intermediate way p

--flows=FLOWS generates INT flows that together output vehicle the specified period

--maxtries=MAXTRIES number of attemps for finding a trip which meets distance constraints

--binomial=N If this is set, the number of departures per sec will be drawn from a binomial distribution with and p=PERIOD/N where PERIOD is the argument give option --period. Tnumber of attemps for finding which meets the distance constraints

-c VCLASS, --vclass=VCLASS, --edge-permission=VCLASS only from and to edges which permit the given ve class

--vehicle-class=VEHICLE_CLASS The vehicle class assigned to the generated trip (adds a standard vType definition to the output

--validate Whether to produce trip output that is already c for connectivity

-v, --verbose tell me what you are doing

Answer 1

Probably the file name association with .py files is broken, see Python Command Line Arguments (Windows). Try to run the script with python explicitly:

python randomTrips.py -n map.net.xml -l 200 -e -o map.trips.xml

Answer 2

I just tried last week. You can search randomTrips.py under SUMO's folder. Then you find the location of randomTrips.py, then you open the cmd and call python to execute it. You also need to specify the net.xml.
