If they are meant to overlap, check the extent of both the layers. One of them should be defined a different coordinate system.
Could you mention the extent of both the layers and their projection system?
I will check that...
Where do I find the extend? in the properties?
Thank you
they have different extend...
How do I change that?
Thank yiu
I don't have an access to any GIS software. If the extent of a shapefile is between 0-180, you need to define a geographic coordinate system (e.g. GCS_WGS_1984)
In ArcCatalog, right-click the shapefile and go to its properties. Edit the spatial reference and define a different coordinate system to check if it falls correctly on Map.
The traffic data is defined a wrong projection.
From ArcCatalog, go to its properties, and edit the spatial reference to Geographic Coordinate System > World > WGS 1984.
Else you could also define it as GCS_North_American_1983.
Check for the more appropriate coordinate system.
Since your current projection system is derived from GCS_North_American_1983, I would try this one first.
I see it.
Thank you...
I will try that.

Hello, I can see the second and thirds together, but not the first... Why will this one not show in the window with the two below? they seem to have the same coordinates??
