ネットワークデータセットにGTFSを追加すると、Error 999999 Topo-Engineが繰り返し発生します

皆さん、こんにちは、<\/P>

<\/P>

私はAdd GTFS to a Network Dataset Toolを使用しています。YouTubeで提供されたデータを使ったチュートリアルは完了し、問題なく動作しました。しかし、自分のドイツからのネットワークとGTFSデータを使ってこれを再現しようとすると、問題が始まります。トランジットラインと停留所を生成する最初のステップはうまくいきます。しかし、2番目のステップであるStop-Street-Connectorsの生成を試みると、Error 999999 Topo-Engineが繰り返し発生します（添付ファイル参照）。この種のエラーを経験したことがあり、解決策を見つけた方はいらっしゃいますか？修士論文のために緊急に修正が必要なので、どんなヒントやアイデアでもありがたく受け付けます。<\/P>

<\/P>

事前に感謝します、Tim<\/P><\/BODY><\/HTML>

Hi Tim. I cannot provide extensive support for this tool because it is now deprecated. The functionality is available out-of-the-box in ArcGIS Pro, so if at all possible, I encourage you to use that instead. It may make your problem simply go away.

With that said: The error message appears to be related to some problem with the geometry of your street features. I suggest you run the Check Geometry and Repair Geometry tools on your streets and then try running Step 2 again.

Hi Melinda,

thanks a lot for your fast reply! I´ve been running the Check Geometry and Repair Geometry Tools. They found one incident, where a Null-Geometry has been found. After fixing (deleting) the flawed object, I re-ran the second step, but still the same error-massage was given.

Oddly, while receiving the error-message, the stops_snaped2street points have been created for each individual stop from my GTFS file. Is it possible, that despite the error, the calculation was still sucessful, so that i can go on with producing the transit enabled network?

Best regards, Tim

The answer is maybe. The error message you posted earlier showed that it failed when running the Integrate tool. The purpose of that tool is to create a vertex in your streets at the location where each Stops_Snapped2Streets point intersects the street. Without these vertices, the network dataset will not actually be connected at those locations, so a traveler would not be able to get on or off the transit line at that location. It could be that just one or two locations caused a problem and the rest worked correctly, in which case the overall errors in your network would be small. On the other hand, possibly the Integrate tool did not add any vertices, in which case your transit lines will be completely disconnected from your streets.

I got the process working now. I clipped my original street data to the area I´m interested in, ran check geometry, fix geometry and integrate. None of these caused any issues.

Then Iset up my Network Dataset, wich also seemed to work. But executing step 3 to get the E-IDs, ArcGIS gave the attached error message.

Is this a known issue and is there an (easy) fix available?

The error message itself refers to Unicode and ascii. It suggest you may have some non-ascii text characters in some of your data, that subsequently cause an issue when part of the processing pipeline you are using tries to handle this. E.g. you can't represent a Chinese character in ascii.

So, are there any special language specific characters in your data? If so, maybe replacing them by safer ascii text characters only solves the issue.
