I have two layers in ArcGIS:

  • Highway layer (9000 data points (or values))
  • Safe zone (4 types of values i.e. safe zone, medium zone, bad zone, and worst zone).

Now I want to do analysis to see how many highways data points fall into zones and how many do not fall in any zone.

I tried to use the Intersect tool to get the result but it didn't produce the desired result. It only gave those points that lie in a safe zone, it didn't return the points that do not lie in a safe zone.

What function should I use?

    You could try a spatial join to add the attributes, but first what geometry types are your datasets? point/line/polygon? The options available are very different depending on what geometry type your safe zones and highways are.

    What was the result of the intersect tool? You should end up with lines within the zones, attributed from both highways and zones, if not check that both datasets have spatial references set and that you haven't selected FID only in your intersect. A picture of your data and results would help conceptualize your operation, can you add one to your question.

    Use Union resources.arcgis.com/en/help/main/10.2/index.html#/Union/… to join all the highways to all the zones and keep the highways outside the zones as well. Union is limited to 2 datasets in basic or standard licensing which should be enough. The output type will be line as the lowest dimension participating in the union (polygon = 2d, line = 1d and point = 0d). So when you say you can't connect highway to union what errors/behaviors are you experiencing?

    The Overlay analysis documentation has diagrams of inputs and output if you're unsure of which tool to use. Intersect does not include polygons not present in both features, but Union does.
