I have uploaded another video on YouTube. This video will teach you how to take a map from OpenStreetMap and turn in into a SUMO simulation (which then can be used in our VANET simulations).

You can view the video here:

Link on OpenStreetMap (downtown orlando):

https://www.openstreetmap.org/export#map=17/28.54222/-81.37243

NetConvert Command:

netconvert --osm-files downtown.osm --output-file downtown.net.xml \
     --geometry.remove --roundabouts.guess --ramps.guess \
     --junctions.join --tls.guess-signals --tls.discard-simple --tls.join

Please refer to How To Create a Network and Simulation in SUMO for randomtrips and duarouter commands.
