Check out this GIS Survey on speed control in Norwich

An intensive traffic study/survey done by 7th grade students with impressive data analysis

Hello Norwich, This story is about a traffic study/survey that was done as a school project for the 7th grade geography students of Windsor Vermont . I attended the presentation that was held at the Police Station training room. The students then went out into the community for a quick tour and to test out some of the equipment that is used in every day speed control.

There are many photos taken by me and a few sent courtesy of Norwich PD. Some real nice data analysis information was provided by the Teacher Keighan Chapman Eaker.  Check out the photos and enjoy the story.

32, 7th grade geography students of Windsor School contributed to the data collection, entry, and analyzed data related to Norwich, VT roads, traffic signs, and recorded police stops.  

First they entered the data containing information about the location of roads and posted speed limit within the NPD jurisdiction. They observed that 51.2% of the roads did not have a posted speed limit sign. Of the roads that did have a posted speed limit sign, 56.4% limit speed to 25 miles per hour.  23.1% of the data suggested that 35 was the second most common speed limit, followed by 30 mph (13.6%) with only 7% of posted signs limited speed to 40 mph.

After they analyzed this data, they then created a new data set in which they recorded police stops.  They collected information related to the location (latitude and longitude), the day, the date, and the time of the stop.  After reviewing this data, they learned that most traffic stops occurred on Wednesdays (19.8%, 119 stops) and Saturdays (19.6%, 118 stops).  Mondays had the fewest with 10.5%, or 63 stops.


Students observed that most stops occurred between 7:00 am and 9:59 am, 11:00am and 12:00pm, and between 1:30pm and 2:45pm.  Students believe these times coincide with commuting times getting to work, and during lunch breaks.





Students also observed that most traffic stops occurred during the summer months and in the fall.  Students attributed these patterns to more drivers on the road for summer vacations and people who drive through Norwich for leaf season.  

As a last step, students entered all of this data into ArcGIS Online and created maps that tell this story spatially.  They observed that most stops occurred in the downtown area of Norwich with many clusters occurring on Main Street, Carpenter Street, and Church Street.

And now the students are ready for a little tour of downtown Norwich and some hands on training/observing.
