  1. Utilizing GIS and EMME/2 for Evaluating the Impacts of Development Nathan Masek GIS Transportation Planner Bernalillo County Public Works Division Albuquerque, New Mexico

  2. Transportation Modeling • Identify travel demand implications of land use and network scenarios • Air quality modeling • Traffic impact analysis (TIAs) • Present quantifiable data/results to decision makers

  3. Identifying Impacts of Future Transportation & Land Use Scenarios • MPO - Develops long and near-term transportation plans - MTP and the TIP • Local agencies - CIPs • Development agreements

  4. Transportation Impact Fees on development • Service Units • Capacity consumed, vehicle miles of lane capacity, LOS D • establish $ fairly • RATIONALNEXUS • Requires specificity by area, LU type

  5. M2probe and EMME/2 • ArcView GIS extension • Reads EMME/2 databank:trip tables/matrices, mode tables, o/d data • Permits timely and efficient “interrogation” of scenarios • Windows-based environment • Integration w/other GIS source data

  6. View Socioeconomic Datasets Link SE input file to TAZ shapefile

  7. M2probe assignment features • Reads EMME/2 data: matrices, tables • Performs AON w/specified impedance - timau, len, gen-cost func., etc. • Performs select link/taz assignments in timely manner

  8. Illustrate Travel Patterns from Matrix Data • Import Origin and Destination Matrices • Attach O/D data to your TAZ theme • Perform assignment by selected TAZ(s)

  9. Illustrate Travel Patterns... • Travel time contours from select nodes • Overlay contours onto TAZs to build access. measures: pop., hh., workers, etc

  10. Illustrate Travel Patterns from Select Link Assignments • Click on a link to do selected link(s) assignments… • Query trip table from EMME/2 databank • Assign trips using ALL links (through trips) • Assign trips using ANY selected link

  11. River Crossing Analysis...

  12. Corridor Analysis... • Select link to identify through trips

  13. Perform Air Quality Analysis... • M2probe can run Mobile5a CO analysis, sel links, network • Graduated line-width, summary tables

  14. Identify development-related impacts • Large subdiv. on fringe of region • Important to ID T impacts • potential intch. rebuild

  15. Identify Development-Related Impacts • Assign trips from devel. TAZs • VMT by Func Class for dev. Trips only
