  1. Simulation-Based Impact Analysis of Signalized Intersections Research Study Site: Intersection of Martin Luther King Drive and Clifton Avenue Kelli Lee S.S/Science Todd Bonds S.S/Science

  2. GOAL:Improve vehicular delay and CO emissions at signalized intersections. • Objectives: • Identify relationship between vehicles’ delay and CO emission; • Identify existing delay and CO emission; • Propose solutions to minimize delay & CO emission.

  3. Data Collection

  4. Methodology

  5. Delay and CO Results • Correlated patterns on the peaks and valleys; • Delay has an obvious impact on the CO concentration.

  6. Existing Conditions • LOSs of the different movements are unbalanced • Overall emitted CO is 44.97g/hr. This is unacceptable! This is good!

  7. Alternative Solution 1 Cycle length remains 90 seconds Phase 5 Phase 6 Phase 1 Phase 2 Phase 3 Phase 4 Phase 3 Phase 1 Phase 2 Phase 4 G: 4.0s Y: 3.0s R: 1.0s G: 9.0s Y: 3.0s R: 1.0s G: 0.5s Y: 3.0s R: 1.0s G: 24.0s Y: 3.6s R: 2.4s G: 13.5s Y: 3.6s R: 2.4s G: 11.0s Y: 3.0s R: 1.0s G: 11.0s Y: 3.0s R: 1.0s G: 6.0s Y: 3.0s R: 1.0s G: 38.0s Y: 3.6s R: 2.4s G: 15.0s Y: 3.6s R: 2.4s

  8. Alternative Solution 1 Satisfactory (from “F”) 2.59s/veh better More Balanced

  9. Alternative Solution 2 • Alternative Solution 1 +

  10. Alternative Solution 2 BEST! BEST!

  11. Conclusions • Correlated patterns on the peaks and valleys • Existing LOS unbalanced; Southbound left turn unacceptable LOS F. • Alternative Solution 1: delay 7.78%, CO emission 4.26%, • Alternative Solution 2: delay 14.68%, CO emission 9.68%, • Recommendations: • Alternative Solution 1 short-term solution • Alternative Solution 2 long-term plan

  12. Questions??? THANK YOU!!
