So Why Study? OMUTCD Ohio Manual of Uniform Traffic Control Devices Signal Warrants 1. Eight-Hour Vehicular Volume 2. Four-Hour Vehicular Volume 3. Peak Hour 4. Pedestrian Volume 5. School Crossing 6. Coordinated Signal System 7. Crash Experience 8. Roadway Network 9. Intersection Near a Grade Crossing Basis for Installation or Removal Advantages & Disadvantages As maintaining agency periodic review of all traffic signals is necessary.

Project Information Analyzed thirteen (13) signalized intersections in the downtown area Reviewed the operations and timing at each location Locations included: 1. High & Wayne 2. High & Main 3. High & Front 4. Spring & Wayne 5. Spring & Main 6. Spring & Front 7. Spring & Ped. #1 8. Spring & Ped #2 9. Spring & Chestnut 10. Spring & Spruce 11. Spring & Pine 12. Spring & Vine 13. Main & South Analysis included: turn movement counts, signal warrant analysis, operations analysis, and recommendations for potential operation improvements.
