Hi, How do I go about building a network dataset of 3 modes of transportation? The aim of my project is to determine shortest routes between locations using the available transportation options. My study area is NYC.
Do I build a network data set for the train lines, bus routes and ferries or is there a way to build them into 1?
How do i design it to make transfers between transportation options?
Also any tutorials or web courses to help with this will be appriciated.
Hi Adeola Awe,
Did you have a look at this tutorial?
It contains 12 exercises and comes with a set of Tutorial data which you can download for free.
And the second exercise is called Creating a multimodal network dataset, so this should cover your question about the 3 modes of transportation: bus, train and ferry.
Hope this helps,
Did you set the connectivity and elevation policies?
Connectivity in the ArcGIS Network Analyst extension begins with the definition of connectivity groups. Each edge source is assigned to exactly one connectivity group, and each junction source can be assigned to one or more connectivity groups. A connectivity group can contain any number of sources. How network elements connect depends on which connectivity groups the elements are in. For example, two edges created from two distinct source feature classes can connect if they are in the same connectivity group. If they are in separate connectivity groups, the edges won't connect unless they are joined by a junction that participates in both connectivity groups.
Egge-Jan Pollé 's Blog Thanks for the prompt reply.
Yes, I have set the connectivity and also the elevation policies? as said in the tutorial
PedestrianTime(Minutes), DriveTime(Minutes) and Meter(Meters) as the options in impedance
