How to make Polylines (roads) represent transportation statistics

Discussion created by dr_phd1 on Apr 21, 2013
Dear All,
           I have a map of Pakistan with the transportation highways as polylines. Suppose I have 5 highways, A, B, C, D, E. I have data for specific highway usage (highway capacity) and I want to make a thematic map such that, the width of lines that represent the highways show the usage. I don't know how to say it correctly, but suppose that the highway usage are as follows:

Highway A = 50,000 cars/hour
Highway B = 26,159 cars/hour
Highway E = 90,000 cars/hour

Now just like a thematic map which portrays the statistics of a map, I want to apply the same concept to the roads, where the width of road display the usage of the highway. Is it possible in ArcMap 10.0. Thanks
