Geocoding a road

[Francisco_AntonioVidale]

I have a polyline that represents a section of a road in his attributes Km established a field of initial and final Km doer of locating a given Km between that range. Ex Accident.
The problem is when I use the locator to locate a specific accident km mark but not me correctly. Not the place you expect considering the initial and final Km.
Aguna ideas?
many Thanks

You are actually trying to perform a linear reference along a route, where as geocoding translates an address (like 1234 Main St) into an X-coordinate and Y-coordinate that the GIS can plot.

May I suggest you start here with the on line help topic of Linear Referencing.
