Přidání GTFS do síťového datasetu stále způsobuje chybu 999999 Topo-Engine

Ahoj všichni,<\/P>

<\/P>

Používám nástroj Přidat GTFS do síťového datasetu. Dokončil jsem tutoriál prezentovaný na YouTube s poskytnutými daty a fungovalo to bez problémů. Nicméně, když se pokusím toto zopakovat s vlastními daty Network a GTFS z Německa, začínají problémy. První krok k vytvoření tras a zastávek funguje dobře. Ale ve druhém kroku, při pokusu o vytvoření Stop-Street-Connectors, stále dostávám chybu 999999 Topo-Engine (viz přiložený soubor). Zažil někdo tento typ chyby a našel nějaké řešení? Velmi bych ocenil jakékoliv tipy a nápady, protože to opravdu naléhavě potřebuji vyřešit pro svou magisterskou práci.<\/P>

<\/P>

Děkuji předem, 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.

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.

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?

Melinda Morang

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.

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
