With the opening of Legacy Parkway and FrontRunner now in service for a few months it is instructive to compare some numbers. Note that my rickety figures are approximate, if there is interest I will spend some time to produce more accurate numbers. However, there is such a large difference between both sets that the conclusions would still be the same.
Each project cost approximately the same amount to build. FrontRunner carries 7,800 passengers a day and Legacy Parkway around 30,000 vehicles a day. In addition, over 1,000 FrontRunner passengers previously rode buses. I don’t have any numbers for how many Legacy Parkway riders are in carpools.
FrontRunner made a slight dent in congestion by removing a small percentage of the traffic from the 140,000 daily car trips along I-15. Legacy Parkway cleared I-15 congestion on its first weekday in operation.
