Assigning Road Segments to Point Data

I want to assign accident data to road segments. How do I do this?

Mapping Center Answer:

This is a geocoding or a linear referencing issue first, rather than a cartography problem that we have resources to address.  The solution will depend on the characteristics of your data, and to set your expectations, this is typically not an easy task.  Data quality issues are frequently encountered and it really depends on what you want to do.  When you write, "accident data", that implies to me that you do not have point locations for the accidents, which means that you cannot simply run something like a spatial join tool to find the nearest road line. 

Please contact Esri's technical support and they will be able to help you relate the data you have to a method for working with it, and give you a hand in getting started.
