Origin-Destination Analysis​​​

​

The analysis identified that many Perrine Bridge users are moving between the southwest and northwest quadrants of the study area. These findings were used to inform the location of potential new river crossings and to help estimate the amount of traffic that would be routed from an existing crossing to a new crossing, if provided.
