Could you please answer the following questions 1) for same OSM map, i am using randomTrips.py for 150 vehicles and 300 vehicles . when i am using traceExporter.py for both , ns2config-output is giving me different floor size values . As per my knowledge, it should give the same area. As u can see here
**************** # set number of nodes set opt(nn) 150 # set mobility file set opt(mf) $opt(config-path) append opt(mf) /scen1 # set start/stop time set opt(start) 0.0 set opt(stop) 1000.0 # set floor size set opt(x) 5609.38 set opt(y) 8812.53 set opt(min-x) 1146.43 set opt(min-y) 3915.69 ************************************** # set number of nodes set opt(nn) 309 # set mobility file set opt(mf) $opt(config-path) append opt(mf) /scen1 # set start/stop time set opt(start) 0.0 set opt(stop) 1000.0 # set floor size set opt(x) 7267.45 set opt(y) 8873.33 set opt(min-x) 737.57 set opt(min-y) 4181.39 *********************************************** Could you please explain is there something wrong . 2) Is there a need to use duarouter with randomTrips.py . 3) Could anyone please tell some database or some link having real traffic data for simulation rgds sims ---------- Forwarded message ---------- From: kavita pandey <[email protected]> Date: Tue, Apr 14, 2015 at 5:43 PM Subject: Re: [sumo-user] route file generation for OSM map To: Jakob Erdmann <[email protected]> thanks a lot for ur reply. there is no need to use duarouter with option 2 . plz confirm . could you give some idea of any database having real traffic data for simulation rgds sims On Tue, Apr 14, 2015 at 12:42 PM, Jakob Erdmann <[email protected]> wrote: > > > 2015-04-14 8:45 GMT+02:00 kavita pandey <[email protected]>: > >> dear all , >> >> I am using OSM map for my simulation.
