MethodologyMethodology

Locations of Traffic Surveys 24 Mid-blocks, 6 Intersections, 9 Outer Cordon and 30 Fuel Stations/ Parking Areas 24 Mid-blocks, 6 Intersections, 9 Outer Cordon and 30 Fuel Stations/ Parking Areas

Summary of Traffic Volume Counts at Selected Mid-block Locations Summary of Traffic Volume Counts at Selected Intersections Maximum Traffic Flow at ITO Bridge (Mid-block) 2.3 Lakh veh/day and NH-8 Toll Plaza (Outer Cordon) with 2.27 Lakh veh/day Maximum Traffic Flow at Ashram Chowk (Mid-block) with 3.65 Lakh veh/day (Flyover Traffic with 1.35 Lakh veh/day)

Typical Hourly Variation and Traffic Composition Lala Lajpath Rai Marg Total Vehicles : 1,92,395/day At Ashram Intersection Total Vehicles : 3,64,871 vehicles/day (1,35,173 v/d flyover traffic)

Pattern of External Traffic 4,64,183 4,31,246

Assignment of traffic flows

Traffic Flow Pattern in Delhi Traffic Flow Pattern in Delhi

 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 ConclusionsConclusions
