Traffic Studies in Planning of Bridges
- Traffic studies need to be carried out to ascertain the amount of traffic that will utilize the New or Widened Bridge 
- This is needed to determine Economic Feasibility of the Bridge  
- For this Services of a Transportation Planner and or Traffic Engineer are required  
- Such Studies are done with help of Traffic Software such as Trans CAD, EMME2 etc. 
- Traffic Studies should provide following information
-    Traffic on Bridge immediately after opening
 - Amount of traffic at various times during life of the Bridge 
- Traffic Mix i.e. number of motorcars, buses, heavy trucks and other vehicles 
- Effect of the new link on existing road network 
- Predominant Origin and Destination of traffic that will use the Bridge 
- Strategic importance of the new/improved Bridge
