Presentation Transcript

  1. Roadway Design Models:Streamlining Conversion for Driving Simulation Shawn Allen The National Advanced Driving Simulator Mid-Continent Transportation Research Symposium 2013

  2. The National Advanced Driving Simulator

  3. Background • Visualization • Look and feel of project • Design proof of concept • Buy-in from project stakeholders • Limited presentation of operational aspects • Driving Simulation • Virtual “computerized” model • Test drive of appearance AND operation • As with visualization, comes in many “flavors”.. Ie, levels of simulator fidelity

  4. Current Parallel to Virtual Testing

  5. Test Drive It Before You Build It • Virtual proof of concept • Build it in a computer before you actually build it in the real world • Determination of satisfactory conditions • Public relations

  6. Visualization Case Studies MnDOT Highway 61 Bridge Project

  7. Hwy 99 Alaskan Way Tunnel

  8. Is a Driving Simulator aGood Test Case? http://www.madsciencemuseum.com/msm/pl/billboard_experiment

  9. Making A Case for Driving Simulators • FAA guidelines permit pilot training on certified simulators to substitute for actual hands-on in the real-world • Extensive simulation use across industry sectors http://newshopper.sulekha.com/boeing-787-flight-simulator_photo_1481525.htm http://www.graphit.hu/Tecnomatix/Products/Plant%20Simulation.aspx

  10. Uses of Driving Simulation for Transportation Visualization • Research • Training • Outreach • Human factors and operational evaluation: • Speed selection • Lane selection • Gap acceptance • Sign comprehension and compliance • Workzone driving performance

  11. FHWA Simulator Case Study • Diverging Diamond Interchange http://www.fhwa.dot.gov/publications/research/safety/07048/

  12. Transportation Model Conversion to Driving Simulator Model Transportation model Driving simulator model

  13. Transportation Design Model • Goal: “hands-free” conversion • Significantly more data than needed for simulation • Access to required elements requires adherence to design standards or robust interrogation algorithms, or both

  14. Elements Required* for Simulation *Characteristics for NADS simulators

  15. Design Model Data Processing Iowa DOT/InTrans Converter Prototype Technical Report

  16. Issues Encountered • Challenges accessing source data • Invalid data in test model (source) Boundary data spikes Triangulated surface errors at overpass

  17. Future Steps • Identify & secure project funding • Proposal under review for University of Iowa to become a University Transportation Center • Improve surface processing to include texture • Improve data algorithms for general-purpose • More model design types • Greater project complexity • Smooth junction connectors • Include additional attributes • Lane markings, signage, etc.
