Gemini intersection

  1. 1. GEMINI INTERSECTION<br />Proposed Modification<br />
  2. 2. Current Scenario<br />Fly over built in 1972<br />One of the busiest intersections <br />Avg. Journey Speed – 18 Km/hr.<br />Intersection Volume ~20,000 PCU @ peak hr. <br />
  3. 3. Existing Conditions<br />Five legged intersection with one fly over<br />Pedestrian facility inadequate<br />Six signal phase due to round-about <br />higher waiting time<br />Poor intersection geometry leading to restrictive traffic movement<br />
  4. 4. Aerial Image<br />
  5. 5. Objectives <br />Pedestrian safety and easy movement<br />Less waiting time for vehicles<br />Smoothening Traffic Flow<br />Minimum structural changes<br />Quick win solution for Short Term<br />Quick look at the Long Term<br />
  6. 6. Proposed Short Term Solution<br />Reduce signal phasing to three (3)<br /><ul><li>Phase 1 – Through traffic flow
  7. 7. Phase 2 – Right turn traffic flow
  8. 8. Phase 3 – Traffic flow from G N Chetty Road</li></ul>Better design geometry<br />Synchronized traffic signals<br />Improved pedestrian facility<br />
  9. 9. Short Term Improvement<br />
  10. 10. Short Term Improvement – Flash Video<br />
  11. 11. Expected Benefits<br />Expected max waiting times<br />Cathedral Road >> Nugambakkam<br />75 sec (from 130 sec)<br />Cathedral Road >> Parrys<br />75 sec (from 130 sec)<br />Nugambakkam >> Teynampet<br />75 sec (from 130 sec)<br />G N Chetty<br />40 Sec<br />Expected waiting time reduction by 40 %<br />Safe pedestrian crossing<br />
  12. 12. Horse Statue – Option 1<br />Relocate both East & West Statue to new locations and beautify the statue with modern touch.<br /><ul><li> Traffic flow totally undisturbed
  13. 13. New look for Gemini Intersection</li></li></ul><li>Horse Statue – Option 2<br />Relocate West side Statue to new location and keep the East side in the same place<br /><ul><li> Traffic flow undisturbed
  14. 14. No major change in the statue location
  15. 15. Historic importance maintained</li></li></ul><li>Horse Statue – Option 3<br />Preserve both statue at the same location<br /><ul><li> Traffic flow disturbed in Nungampakkam to Saidapet Right Movement
  16. 16. Traffic flow disturbed in GN Chetty Road movement towards Parrys & Cathedral Road</li></li></ul><li>Additional Points<br />Integrate with Arcot Road/Nugambakkam junction<br />Ispahani/Church/MOP <br />Bus bay<br />Pedestrian crossing<br />
  17. 17. Proposed Long Term Option<br />Multi Level Fly Over<br />
  18. 18. Proposed Long Term Option –Views<br />
  19. 19. Proposed Long Term Option – Plan View<br />Multi Level Fly over<br />Ramp to Saidapet<br />
  20. 20. Proposed Long Term Option –Views<br />Nungampakkam to Beach Fly over<br />Ramp to Saidapet<br />Ramp to Parrys<br />
  21. 21. Proposed Long Term Option –Views<br />Nungampakkam to Beach Fly over<br />
  22. 22. Proposed Long Term Option –Views<br />Nungampakkam to Beach Fly over<br />
  23. 23. Proposed Long Term Option –Views<br />
  24. 24. Proposed Long Term Option<br />Signal Phase required only for Pedestrian movement<br />Uninterrupted flow along every direction<br />No modification on existing fly over configuration<br />Pedestrian safety is high on the Ground Level<br />Seamless connectivity through multiple legs<br />Cost will be around 120 to 150 crores (Approx. estimation)<br />
