comment Highlight roads that are within a buffer or overlapping buffer
Can you identify what you mean by "highlight". Are you looking at selecting them, do analysis on them, or outputting them to a new layer?

comment How to calculate wait time on a one-lane road with two-way travel?
This and your other question seem to me as true traffic engineering problems rather than GIS ones. there are a lot of factors involved in such an analysis, such as arrival rate, speeds, type of traffic control, acceptable levels of service, peakhour factors, etc.

comment find edges inside and outside of polygon in NetworkX
Are you importing the routes and polygons as shp files? If so, can you identify which nodes the polygons are in and then do an intersection?

comment How can I configure Travel Modes in ArcGis?
Can you show us some screenshots of what you have done and maybe we can better assess the situation that way?

comment NetworkX: Saving Shortest path of OpenStreetMap data as an OGR friendly format
Shapefile is part of the pyshp library so it worked for me as well but perhaps if the solution could be geared towards Fiona that'll be perfect :D

comment NetworkX: Saving Shortest path of OpenStreetMap data as an OGR friendly format
Answer works! Curious, do I need to import pyshp to do so? is pyshp part of Geopandas or fiona?

Awesome thanks. That worked perfectly :D Perhaps reflect that in the answer. I will also accept it

comment GeoPandas: return lat and long of a centroid point
Sounds good. The reason I'm using a dataframe is that i'm grouping my centroids by a field in my shape file as follows: for index, row in zones.iterrows(): if row['CMANAME'] == u'zone_name':

comment GeoPandas: return lat and long of a centroid point
Although the code works, it seems that list(...) is returning a lot more points than what I need. I have 30 zones so I should only have 30 centroids. when expanding to list(...) it's returning thousands of points

Are you looking for if field_a == 'foo' then field_b = 'new stuff'?

comment Finding Network Distance Between Specific Pairs
Unfortunately complicated questions like this will require Python or software packages like TransCAD that can let you answer such questions right out of the box. Perhaps, we can help you find the solution, IS your road data already in network form? do you have a list of the pairs you want to iterate over?

comment How can I get a remote village transportation network from openstreetmap?
So are you trying to extract OSM data so that you can input it in the simulator package you're using? if that's the case, can you provide a data format required for the data to be in?

Thanks for providing the info about shapely. I edited my question based on your answer if you'd like :D

comment Which spatial bundling or grouping algorithm optimally groups elements by attribute?
I am still having troubles solving this problem! What I tried to do is assign the each road segment a k factor that ranges let's say between 0 and 1. 0 means that you can't alternate the time of the project and the closer you get to 1, the further ahead you can push or bring a project in from future years. Once I get to that stage, I am not sure on how to proceed. I am aware that it's an optimization problem but I can't pinpoint exactly how to solve it.

comment Creating a point file with python from a pdf file
you have a lot of documents, it seems to me that you're better off putting that data in a csv then making a geodatabase out of it. Use ArcPy, to do the work on the GDB

Do you want to edit the answer to reflect on the comment and how it can't be done so I can accept it?
