The Impact of Closing Streets for a Parade • We’re going to do a quick analysis of the impact of closing down some strees in downtown Flintbury for a parade. • We’ll use the network, shortest path, and matrix capabilities of Trans. CAD to compare the person-hours spent driving in Flintbury under normal conditions with the personhours spent driving with the parade route closed. 11/25/2020 2
