The node study type has two common uses.  The first is for state or county road departments that have organized their systems into nodes and links.  The second is for cities who have assigned a unique identifier to specific locations(like intersections) on their roadway system.  This method of locating crashes can greatly improve the accuracy and efficiency of a study.  This is because there are no chances of spelling mistakes or duplicate location names.  Nodes can also be useful for identifying related individual parts of a larger traffic control location.  (such as two divided boulevards intersecting)

 

The node study type fully supports node aliases when available.  

 

The parameters you'll need to provide for this study type are:

•Start date

•End date

•Node ID
