Cheryl, to clarify, a CE generated lot shape will have access to the street parameters? What about other rule attributes/parameters? What about imported data?  David ... View more

I am going to go against the grain and say I no longer do this in CityEngine. Christian Iten‌ has great suggestions for doing this work in CityEngine, but if you feel like GIS is your real pocket knife I would do the work there.  The tools I typically use include:  1. https://desktop.arcgis.com/en/arcmap/10.3/tools/cartography-toolbox/merge-divided-roads.htm 2. https://desktop.arcgis.com/en/arcmap/10.3/tools/cartography-toolbox/collapse-dual-lines-to-centerline.htm 3. https://pro.arcgis.com/en/pro-app/tool-reference/data-management/feature-to-line.htm 4. Sometimes: https://github.com/d-wasserman/feature-line-split (Feature Line Whiskers to get width attributes from other datasets).  Editing in GIS is just easier, and the tools to deal with attribute changes from dual carriage ways are just easier to manage there. If you go with a large enough study area, a cross-sectional database is just easier to maintain in GIS. Once imported, then I make sure everything is positioned with the tools mentioned here.  ...

If you add David Wasserman‌, I typically try to answer within the week. I echo your frustrations, and I realize it is not enough to just say go through the tutorials. A lot of learning comes from experimentation I found, but a lot can be found from the original tutorials.  A lot of us want you to succeed in your efforts, just tag us, and we will collectively build up the knowledge base one article at a time.  ...

I ran into this issue, and while you did not have the correct answer - I literally said to my self "If I search Dan Patterson I might find good forum to check this".  Bingo... ... View more

Supplementary information on the rule can be read here too if you want more information about it:  https://community.esri.com/docs/DOC-6251-complete-street-rule-documentation-user-guidepdf  ... View more

Hi All,  Sorry I have not logged on in a while.  Generally when you add models, you need to make sure they are aligned to match the OBJs already in the folder. I have been also looking for new vehicles/objs to add to the rule so if you have anything that you think might be worth adding, let me know.  Once you create the files, make sure they generally match the naming conventions in the folder. The rule searches for specific objs using wild cards when allocating vehicles. So, if you have a plain car, don't label it as a Taxi_XXXX.obj. David ... View more

It can't fix everything unfortunately, but I felt it might help.  ... View more

Hi Andrew,  Glad I wrote that in the guide! Yes, that is the solution- change the sidewalk settings.  Sorry I was at TRB 2019 (conference) when you posted.  Glad this was figured out.  ... View more

Hi Majd,  I would review the simplify and clean up graph tools in the documentation. https://cehelp.esri.com/help/index.jsp?topic=/com.procedural.cityengine.help/html/manual/sn/cleanup.html Let me know if this helps.  David ... View more

While this thread is old, it is worth providing an update.  https://community.esri.com/people/GTaylor-esristaff/blog/2018/11/02/3d-street-sign-library-for-arcgis-collector  Esri has developed a stand alone US sign rule that can take custom textures. It is also located in the Complete Street Rule Github in the "Stamp_Rules" folder.  Hope this helps future users! ... View more

Hi Claudia,  Understood. Currently the tool only adjusts the MetHdWyLim field.  However, this is a python based tool that is easy to modify to this purpose I think.  At Line 290 in the tool, you should be able to modify the code to do this.  Currently it reads:             frequency_dataframe["MetHdWyLim"].where(frequency_dataframe["AvgHeadway"] <= FrequencyThreshold, np.nan,                                                     inplace=True) You might want: frequency_dataframe["MetHdWyLim"].where(frequency_dataframe["AvgHeadway"] <= FrequencyThreshold, np.nan,                                                     inplace=True)             frequency_dataframe["NumTrips"].where(frequency_dataframe["AvgHeadway"] <= FrequencyThreshold, np.nan,                                                     inplace=True)                          frequency_dataframe["NumTripsPerHr"].where(frequency_dataframe["AvgHeadway"] <= FrequencyThreshold, np.nan,                                                     inplace=True) Disclaimer, I have not tested this code, but should work.  ...

Hi Claudia,  I think I understand the issue here.  The Count High Frequency Routes at Stops tool uses the headway threshold not to change the trip counts in the time period observed, but to change the number of routes that go through the stop that are counted under the Met Headway Limit field. This is the number of routes that meet that headway limit chosen by the tool. The number of trips/trips per hour are exactly the same as the other tools. Do you want the behavior to be that it only counts the trips of those stops that meet the headway threshold?  David ... View more

Hi Claudia N‌,  I wrote the tool in question. I downloaded GTFS dataset in question and noticed it was mulitple zip files nested inside another zip file. Are you running the tool on just one of the directories of the 11 or all of them at once? Do the other tools work on the data as expected?  David ... View more

That is a good question. I would have to run it to find out. I have not actually tried the workflow I am writing up, but I am trying to think of an approach that matched my understanding of the python API. If you try it let me know.  ... View more
