The table below lists the speeds $($mph$)$ and densities $($vpm$)$ for an urban freeway. Use Excel to plot the three fundamental diagrams and use trend lines to show the relationshipbetween traffic flow, speed and density. From these diagrams, find the free flow speed $($FFS$),$ the jam density $($Dj$),$ and the maximum flow $($qmax$).$ Also, determine the average space headway and time headway at maximum flow condition.The results of this lab assignment in the forms of tables and figures should be uploaded toCanvas by the end of todays meeting
