Hi Jakob, I updated the wiki to show the new option name. Thanks for the hint. (By the way, how often is the web doc updated by the wiki content?) Originally, we wanted the output of ActivityGen to be a trip file. However at this time, a trip could not contain intermediate stops, only the start and the end point. So we decided to write a broken route file. This is not nice though. I guess Daniel mentioned at this time that intermediate stops could come some when in the future. Do you know more about it? Will such an extended trip definition be possible? I would change the output of ActivityGen then.

I believe I copied those options from one of the examples on the website since they sounded like a good idea. It appears that when some routes have loops removed they aren't valid any more, which must be the source of fictitious departure positions. > > > > What happens when I don't remove loops in routes? > > > > Best, > > Conrad (Alec) Gosse, MUEP > > Doctoral Candidate: Civil & > > Environmental Engineering > > University of Virginia > > Charlottesville, VA > > > > On Jan 23, 2012, at 9:14 AM, Simon Siemens wrote: > > > >> Dear Conrad, > >> > >> I took your files and executed the following commands on them.

Please let me know if something else seems amiss. I've just started with SUMO and certainly don't have everything perfect on my end. I think this might explain some of the bizarre looking travel patterns I've seen watching the GUI view of my network under simulation though. > >>> > >>> Are you effectively maintaining activitygen? > >>> > >>> Thanks, > >>> Conrad (Alec) Gosse, MUEP > >>> Doctoral Candidate: Civil & > >>> Environmental Engineering > >>> University of Virginia > >>> Charlottesville, VA > >>> > >>> On Jan 19, 2012, at 2:26 AM, Simon Siemens wrote: > >>> > >>>> Dear Conrad, dear Joerg, > >>>> > >>>> I try to follow the postings about ActivityGen and to fix bugs.

Specifically, many of the temporary routes produced by activitygen have vehicles departing from position values larger than the length of the edge in question. This situation is carried through the duarouter --repair step and results in numerous similar SUMO errors, e.g.: > >>>>>> Error: Vehicle 'h22958c1:1' will not be able to depart at the given position! > >>>>>> > >>>>>> The only thing that I'm generating with my own code in this process is the land use, which consists of many entries similar to this in the stats file: > >>>>>> <street edge="1/1to1/2" population="0.171651" workPosition="0.817595" /> > >>>>>> > >>>>>> I've just recompiled from SVN sources; why would activitygen originate trips from positions past the limits of an edge? > >>>>>> > >>>>>> Best, > >>>>>> Conrad (Alec) Gosse, MUEP > >>>>>> Doctoral Candidate: Civil& > >>>>>> Environmental Engineering > >>>>>> University of Virginia > >>>>>> Charlottesville, VA > >>>>>> > >>>>>> > >>>>>> ------------------------------------------------------------------------------ > >>>>>> Keep Your Developer Skills Current with LearnDevNow! > >>>>>> The most comprehensive online learning library for Microsoft developers > >>>>>> is just $99.99!
