3. Delivery 2: Radiometry Improvements
Finished work on the new “simple” radiometry solver that drives high fidelity radiometry very quickly Resolved issues with specular lobe falloff modeling that created artifacts in Delivery 1

Delivery 2: CityEngine Integration
Resolved issues with OSM/SUMO/CityEngine lane integration
Added road context modeling in CityEngine, adding parking/breakdown lanes, gutters, verges, driveways, curbs and sidewalks
Driveways and shoulder space will act as nodes for SUMO integration using edge ID and position information extracted from CityEngine
Regional variation still limited by buggy attribute mapping in CityEngine -- attempting to switch to scripting
correct lanes
for OSM and
SUMO integration
driveway/access nodes for lot design and SUMO
integrated sidewalks, road verges, crosswalks, driveways, curbs, and shoulders

5. Delivery 2: SUMO
Meeting with MITRE on Monday to learn more about SUMO usage
Delivery has a trip/route for an 8 vehicle caravan with a midway split (2 vehicles leave caravan)
Caravan mechanics (lead/trailing car and “following” behavior) are hacked in using lane restrictions
Had to reduce number of cars to 1000
Need better vehicle articulation/placement
Intent is to link trip start/end locations to driveway nodes and add non-networked simulation data for parking lot motion

6. Delivery 2: Added DIRSIG Tools
Added addition population distribution tools allowing arbitrary discrete distributions of object geometry and sub-object material variants
Also added a simple (static) temporal variant tool that allows objects to be turned on/off on a daily time schedule (e.g. on between 2 and 3pm)

7. Lessons Learned: Workflow Modifications
Running up against many issues maintaining the integrity of road networks across parallel workflows with final integration in DIRSIG
Vehicle motion
Road geometry
SUMO routes
CE shapes
OSM
SUMO network
CE graph
DIRSIG
Future approach is to use the CityEngine generated graph and shapes to generate a new OSM file that matches what is modeled

8. Future Work
Scene Fidelity Improvement: 
• Texture improvements for buildings and roads
• Lot design and better building models
• Linking node data to lot design
• Road signage/lights and general clutter
• Additional attributed vehicle models
• Additional tree species and distributions
Dynamic Scene Content:
• More sophisticated traffic modeling
• Significant increase in population size
• Un-animated node start/stops
