An analysis (of traffic or anything else)is only as good as its data: Part 2

Heather is lead researcher on Cherenzia's traffic analysis.  Here is her post on trip generation.

       Thanks to all involved in our Traffic Count!  Whether you were at the station distributing brochures, sharing information, counting movements or passing through as one of the many vehicles and pedestrians - I thank you greatly.  I have compiled the data and provided an overview, as well as some supporting details as to why we felt compelled to spend part of our weekend at an intersection of our beloved loop.  From 8 a.m. to 9 a.m., there were 116 vehicle movements and 32 pedestrian movements.  The following hour resulted in 230 vehicle movements and 16 pedestrian movements.
       What does all this mean?  Our neighborhood streets are already congested but to add the volume of attached housing may result in dangerous circumstances.  Unlike other areas with this high volume of movements, our pedestrians have no sidewalks for safety.
        Our neighborhood is on a peninsula with two main means of egress.  Spring of 2010 showed us our vulnerability if required to evacuate.  Parts of Mechanic Street, River Road and Mary Hall were all under water.  The structural integrity of the bridge on Greenhaven Road, over Wequetequock Cove, was in question and closed due to a partial collapse.
