Applicability of Paths Derived in Regional
Planning Models to Traffic Micro-Simulation

• Paul Ricotta, P.E., Caliper Corporation
• Jon Fricker, PhD, Purdue University
• Kent Anderson, CAMPO (Columbus, IN)
• Daniel Morgan, Caliper Corporation

2
Case Approach

• Generate simulation network from planning network
• Add network detail, signals, and signal timings
• Run planning model
• Run 2-hour AM simulation (with trip table from
  step 3)
• Generate, map, and tabulate congestion MOEs from
  planning model (step 3)
• Generate, map, and tabulate congestion MOEs from
  simulation model (step 4)
• Compare and contrast (between steps 5 6)

Case Overview Geographic Scale

• 1 county (Bartholomew) and parts of two others
  (Johnson Shelby)
• 8800 links, 6700 nodes, 85 TAZs
• 3,000 lane-miles
• 108 signalized intersections
• 22 miles E-W x
• 28 miles N-S
• Freeways, arterials, local streets, commercial,
  residential
