First parameter to MakeFeatureLayer should be a input feature class or layer.
You are passing x which is a tuple of the values of 'CONCAT_T', 'AREA', for example ("somevalue", 1000). Maybe it should be 'talhoes_layer' instead?
If you have ArcMap >= 10.5 (I think), you can use Split By Attributes:
Splits an input dataset by unique attributes

The single equals sign (=) is used for assigning a value, not testing for equality. To test for equality, use the double equals sign (==).
So instead of:
if int([Most_Recen]) = 0:
it should be:
if int([Most_Recen]) == 0:
Although, since zero (0) evaluates to false, you could skip the equality test altogether, and just check the "truthiness" of the ...

It sounds like you are trying to use the Water Geometric Network Editing and Analysis solution which is part of ArcGIS Solutions for Water:
Water Geometric Network Editing and Analysis requires specific technical experience and software
including
ArcMap (Standard or Advanced) 10.2.1, 10.4 - 10.7
Consequently, it appears that your ArcGIS Desktop ...

I do not think this is possible in ModelBuilder.
But you could create a model that :
convert the line vertex to point
add XY (and if needed ZM) coordinate to the newly created point
select some of the point
Export a table with the coordinate you're after

Below is 2D solution to replace cross-sections approach I suggested in comments. Picture shows routes as lines:
Place multiple points on them to represent width of corridor, by using linear referencing for example:
Use kernel density (EXPECTED_COUNTS) on above points with population
field NONE, call output COUNT.
Use kernel density (EXPECTED_COUNTS) on ...

If you follow the instructions in how to Add Orfeo Toolbox to QGIS 3.X, it should work properly.
There are two main steps you need to do:
Download the Orfeo library Download the matching version for your
operational system in the following address:
https://www.orfeo-toolbox.org/orfeo-toolbox-6-6-is-out/
Download the Orfeo plugin files from gitlab
You need ...

If anyone wants to do this with r, I found a script written by Barry Rowlingson on R-sig-geo that still works fairly well.
Two functions: one computes evenly spaced points along a set of xy coordinates, the other works out the end point of transects centered on those points:
# How to generate perpendicular transects along a line feature
evenspace <- ...

What you're describing, while pretty straightforward, simply isn't possible in the standard AGOL Map Viewer. The web web doesn't have capabilities for inter-layer actions like that. In a custom web map built with the Arcgis JavaScript API, it would be simple, but probably involves more coding than you're looking for.
If you want an off-the-shelf option that ...

You can use the format() method to include specific values inside your strings. Furthermore, I think the field name does not have to be inside quotes but I may be wrong. You could write the following inside your for loop:
for row in cursor:
fid = row[0].zfill(4)
query = '''FID_{}_T <> -1 AND FID_{}_L <> - 1'''.format(fid, fid)

All the links from the previous answers did not work anymore (at least for me) as of Nov 2019. The ColorBrewer.style file for ArcGIS 10.xxx can be downloaded from here.
Copy the .style file to C:\Program Files (x86)\ArcGIS\Desktop10.6\Styles (for ArcGIS 10.6). Then add any shapefile to a blank ArcMap document.
Double click on the layer, go to Symbology ...

Assuming that each road segment that you want to buffer is available as a line feature you could use the Buffer tool and specify the buffer size using a buffer field:
The distance around the input features that will be buffered.
Distances can be provided as either a value representing a linear
distance or as a field from the input features that ...

If your destination is an ESRI geodatabase (enterprise geodatabase or file geodatabase).
Use the "Feature Class to Feature Class" tool, or the "Copy Features" tool.
For more information (including the difference between the two tools) see: Difference between Copy Features and Feature Class to Feature Class tools?
OR, if you only want the attributes, and ...

You can download the .style file at this Git repo: https://github.com/ISUEOGTP/GISTaskSheet mentioned in these PDF instructions: https://indicator.extension.iastate.edu/projects/tasksheets/reports/PM2082-14e.pdf
These instructions also explain how to import it once you have it.

Reorder Fields
Author: Luke Savage, GISP
Contributor: Brandon Whitney
Created: July 10, 2020
Tested: ArcGIS 10.8
Purpose: To reorder GIS fields that have like fields per feature class and table so those fields are reordered in front of all the rest of the fields. This works on the complete dataset. Make sure fields exist and are aliased properly. Code ...

The Previous Answers worked for QGIS 2.x.
If you are reading this after 2020, you will find that the Answers don't work. What Works with QGIS 3.x is the plugin called IBAMA Processing.
Install this plugin, and then you will get the `Create Footprint of Images' tool/algorithm in the Processing Toolbox.
