Planejamento de Viagens de Transporte Público com Network Analyst

GaryBennett

No ArcGIS Pro Network Analyst, ele pode ser usado para planejar viagens de transporte público por rota? Eu tenho um arquivo de estudantes de escola pública que geocodifiquei, e gostaria de usar o Network Analyst para gerar a viagem de volta para casa para cada estudante. Preciso de um arquivo de saída que inclua a rota designada da escola até a casa. Há um requisito de 1,5 milha para obter um passe de ônibus. Qualquer pessoa que mora a menos de 1,5 milha da escola é considerada um pedestre (Sem passe de ônibus).<\/P>

Atenciosamente,<\/P>

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.
