Analyste Réseau Planification des Trajets en Transport Public

GaryBennett

Dans ArcGIS Pro Network Analyst, peut-il être utilisé pour planifier des trajets en transport public par itinéraire ? J'ai un fichier d'élèves d'école publique que j'ai géocodé, et je voudrais utiliser Network Analyst pour générer le trajet de retour à la maison pour chaque élève. J'ai besoin d'un fichier de sortie qui inclut l'itinéraire attribué de l'école à la maison.  Il y a une exigence de 1,5 mile pour obtenir un laissez-passer de bus.  Toute personne vivant à moins de 1,5 mile de l'école est considérée comme un marcheur (pas de laissez-passer de bus).

Cordialement,

This is a big question, so let's try to break it down and generate some ideas.

The first thing you need to do is filter out the students who aren't eligible for bus passes because they live within the 1.5-mile distance of the school (I presume you're looking at network distance rather than straight-line distance.).  The best way to do this is to use an Origin Destination Cost Matrix with a distance cutoff.  This tutorial may help: https://pro.arcgis.com/en/pro-app/latest/help/analysis/networks/od-cost-matrix-tutorial.htm 

Next, I presume the students will be using scheduled public transit service rather than riding school buses.  Assuming you have GTFS data for the transit system, you can incorporate these public transit schedules into a network dataset.  Here's a tutorial that walks you through that process: https://pro.arcgis.com/en/pro-app/latest/help/analysis/networks/create-and-use-a-network-dataset-with-public-transit-data.htm.  Once you have the network created, you can model travel by public transit.

Since students are presumably dismissed from school at a particular time of day, you can eliminate some of the challenge in transit travel time calculations by assuming a given starting time of day.  You can calculate the routes of these students from school to home at that time of day using the Route solver.  The challenge will be in extracting information about the actual transit lines taken because our solvers don't report this information.  However, you can download the Transit Network Analysis Tools from here: https://github.com/Esri/public-transit-tools.  The Copy Traversed Source Features With Transit tool will give you more detailed information about which transit lines got used for each route: https://github.com/Esri/public-transit-tools/blob/master/transit-network-analysis-tools/UsersGuide.md#Copy-Traversed-Source-Features-With-Transit 

Hope this helps get you started.
