How to include gates in a road network

Gisbert61 — Mon, 08 Jan 2024 15:26:59 GMT

Hi All,

I'm new to the networking stuff, did a tutorial once but no real experience.

I have a layer of polylines for roads and a point layer containing several types of gates, bridges and other 'obstructions' in those roads.

I would like to create a network in which those obstructions are accounted for when I search for the best route from A to B. For example a bridge may be to weak for a truck, a gate may be to narrow for a car but not for hikers, a cattle grid is not passable for livestock but is for all other traffic.

How can I include the obstructions in the network? Is there documentation you can point me to?

Thanks for your time!

Bert

sounds like you are interested in barriers and travel modes

Barriers is not the correct way to model this, since those are meant to model temporary obstructions. It sounds like what you want is to create restriction attributes modeling bridge weight limits, cattle grids, etc. and then some travel modes modeling different vehicle types that can and can't use those features.

If you haven't done this one already, this is the most relevant tutorial for you to do: https://pro.arcgis.com/en/pro-app/latest/help/analysis/networks/how-to-create-a-usable-network-dataset.htm

Relevant conceptual documentation:

Restriction attributes: https://pro.arcgis.com/en/pro-app/latest/help/analysis/networks/restriction-attributes.htm
Travel modes: https://pro.arcgis.com/en/pro-app/latest/help/analysis/networks/travel-modes.htm

Thanks both Melinda and Dan. I think Melinda is right but the links Dan posted are very usefull as wel as we do have temporary restrictions as wel.
