How to split GPS data points into different road function class (eg. Interstate, arterial etc.,)

rohitj

So we have a lot of gps data points for a test vehicle which needs to be analyzed. My attribute table has a lot of columns like vehicle speed, acceleration etc., I have added XY dataset and all the points are visible and I can represent each of attributes in color codes over a base map. Is there any way to split the data points like when the vehicle was in Interstate, arterial, etc., so that I can do some statistical analysis on that split data.

with a spatial join, attributes are not used, but the geometry is used. In essence, you can find the highway closest to a given point by spatially joining the polyline to the point

Thank you again. Its working flawless..

That is because you aren't using a shapefile residing in a folder...what it was tested on and designed to work with

hey,

I am getting this error message when m trying to execute

this tool does not exist.

Failed to execute (SplitLayerByAttributes)

hey,

I have tried that. But the thing is the road classification layer is not having any attribute table to match it to my current shape file. Is there any other way?

I am assuming that you have ruled out Joins and Relates or more specifically, the Spatial Join for some reason? or am I wrong?

Hey Dan Patterson,

Thanks for the reply, The problem is I am not having the road function class as an attribute in the shape file. Is there a way to add that attribute automatically to the present shape file. Because It cant be done manually as its a big data file with almost 30000 points.

I have collected Road class map from the state department of transportation website. But I can use that as a overlay in a separate layer and it doesn't have any attributes. forum 1.PNG

I am inserting the image for your reference. The road functional class now displays the different class of roads in different colors. I want to add this attribute to my shape file and split it accordingly. Is there a way to do it. Please help!

You can produce separate shapefiles using the SplitLayerByAttributes toolbox if you have data in a field that will allow for separation according to some class.
