I have followed the above process and trying to generate random route using osm.map. my system variable is set for python.I used manual path for randomTrips.py in windows 7 following the above.

current_dir>python D:\source\sumo-0.21.0\tools\trip\randomTrips.py -n gerching.net.xml -e 100 -l

the above line worked and created trips.trips xml file. i have following files now in current_dir: gerching.net gerching.osm gerching.poly typemap trips.trips

current_dir>python D:\source\sumo-0.21.0\tools\trip\randomTrips.py -n gerching.net.xml -r gerching.rou.xml -e 100 -l calling D:\source\sumo-0.21.0\tools\trip....\bin\duarouter -n gerching.net.xm l -t trips.trips.xml -o gerching.rou.xml –ignore-errors –begin 0 –end 50.0 – no-step-log Traceback (most recent call last): File “D:\source\sumo-0.21.0\tools\trip\randomTrips.py”, line 209, in main(get_options()) File "D:\source\sumo-0.21.0\tools\trip\randomTrips.py", line 205, in main subprocess.call(args) File "C:\Python27\lib\subprocess.py", line 522, in call return Popen(*popenargs, **kwargs).wait() File "C:\Python27\lib\subprocess.py", line 710, in __init__ errread, errwrite) File "C:\Python27\lib\subprocess.py", line 958, in _execute_child startupinfo) WindowsError: [Error 2] The system cannot find the file specified

It does not create any file for the above command. How to solve it? Thanks in advance
