Network Analyst 公共交通旅行計画

GaryBennett

ArcGIS Pro Network Analystでは、ルートごとに公共交通の旅行を計画することができますか？私はジオコーディングした公立学校の学生ファイルを持っており、Network Analystを使って各学生の自宅への旅行経路を生成したいと考えています。学校から自宅までの割り当てられたルーティングを含む出力ファイルが必要です。バスパスを取得するには1.5マイルの要件があります。学校から1.5マイル未満に住んでいる人は徒歩者（バスパスなし）と見なされます。<\/P>

よろしくお願いいたします。<\/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.
