Growth of Population in Metropolitan Cities
Delhi has more than 5 per annum (Mumbai
3,Kolkata 2, Chennai 3)
Delhi has 1.3 of India Population (Area is only
0.05 of country) Presently Delhi has about 17.5
millions

Conclusions

• High Traffic flows observed are observed at CBD
  areas and on Major National Highways
• ITO bridge carries maximum traffic flow around
  2.3 lac /day
• NH8 Delhi- Gurgaon Expressway carries Maximum
  Traffic Flow 2.27 lac/day
• Ashram Intersection carries maximum around
  3.6lac/day
• Future Applications
• For Traffic Congestion management
• For Traffic Pollution Loads from Traffic
• For Dynamic Traffic Assignment
