00. SUMO Development Update - dataandcrowd/GlasgowLEZ_SUMO GitHub Wiki

• Expanded to 5km x 5km (25m²) using the QGIS OSM downloader
• It used to be approximately 2km x 2km
• Pros: Wider area to consider in the inbound and outbound vehicles
• Cons: Delay in loading and moving screen

• Tested for 3600 time unit
• One issue: traffic bottleneck detected at the junction of M8 sliproad to Royal Infirmary

• Add sidewalks
• Test for additional vehicles
• Test for a longer period

1. Added a new folder 03_Expand-Area in the Glasgow_SUMO folder.
2. Unzip the osm and created the network files link to the file

netconvert --osm-files glasgow.osm -o glasgow.net.xml --junctions.join --roundabouts.guess --osm.elevation --tls.guess --osm.sidewalks --tls.ignore-internal-junction-jam

Since the initial simulation caused some errors in some junctions, we added the --tls.ignore-internal-junction-jam function

3. Import polygons from OSM-data and produces a sumo-polygon file

polyconvert --net-file glasgow.net.xml --osm-files glasgow.osm --type-file typemap.xml -o glasgow.poly.xml 

4. Generate a random trip for vehicles and pedestrians

python3 randomTrips.py -n glasgow.net.xml -r passenger_routes.rou.xml  -o passenger_trips.xml -e 600 -p 0.1 --vehicle-class passenger --trip-attributes="color=\"255,255,255\""
python3 randomTrips.py -n glasgow.net.xml -r ped_routes.rou.xml  -o ped_trips.xml -e 600 -p 5 --pedestrians
