Presentation Transcript

  1. Alex Bigazzi • Civil engineering undergraduate, senior (focus on transportation) • Areas of Interest • Transp. system sustainability • Modeling transp. emissions and diffusion • Honor Program – Thesis topic: Carbon Sponsoring for Personal Travel Alex Bigazzi

  2. ‘Greening’ PORTAL • Sustainability performance measures for the transportation data archive at PSU • Emissions: currently MOBILE 6.2, will use MOVES • Fuel Consumption • Cost of Delay • Personal Mobility (PHT, PHD, PMT) Alex Bigazzi

  3. ITS Data Aggregation Effects • Errors from temporal aggregation • Data source: disaggregate speeds from loop data • Event: car passes over loop • Error 1: Time resolution • Shock speed Alex Bigazzi

  4. ITS Data Aggregation Effects • Error 2: Parameter distribution • Speed distribution narrows • Underestimate emissions, delay • Travel time errors from using time mean speed • Underestimate delay • Corrected using harmonic mean • Can be estimated w/ variance Alex Bigazzi

  5. CarbonSponsor.org • Framework for individuals to seek direct, voluntary carbon offsets for personal travel • Targets carbon reductions outside of current monetary-based offset programs • Project objectives: • Establish calculation methods for carbon outputs • Develop effective and simple online interface • Analyze initial feedback from pilot users Alex Bigazzi
