I want to create a hyperlink to picture which is returned by a php-Site with parameter. The arcade expression works fine var urlsource = "https://www.xxx.de/image.php?"; var params = hstnr: $feature.haltestellen_hstnr, mastnr: mast, position: 0, type: 0 ; return urlsource + UrlEncode(params); But the link in the popup include additional strings per parameter '#38' so that the browser can't the file. (https://www.xxx.de/image.php?hstnr=1090543&mastnr=2&position=0&type=0) The idea is to create link which also works with php-paramters (&=xxx)

with the parameter --no-pin and a new environment I could install movingpandas and get it to run. At the moment without errors! Thanks !

‎01-19-2021

The cause of error could be the old conda version, which ships with Arcgis Pro https://github.com/conda/conda-build/issues/3915

Even with a fresh copy of my default environment I get the same error. conda install -c conda-forge movingpandas --dry-run Fetching package metadata ............... Solving package specifications: InvalidSpecError: Invalid spec: =20190808

Thanks conda install -c conda-forge movingpandas --dry-run throws an error InvalidSpecError: Invalid spec: =20190808 I will try it with a new clone of my standard environment

I try to install the python packages movingpandas with Arcgis Pro 2.7 It is available in the list "add packages". But I can't install it with the install button or with the conda prompt and "conda install movingpandas". Conda search movingpandas doesn't return any result. Any ideas? Tim

Hi after a while running the Jupyter Notebook on ArcGIS Pro 2.4.1 (Windows 10) on a cloned environment I geta Kernel error with the following message Traceback (most recent call last): File "C:\Users\xxxx\AppData\Local\ESRI\conda\envs\arcgispro-py3-clone_zvbn_02\lib\site-packages\tornado\web.py", line 1699, in _execute result = await result File "C:\Users\xxxx\AppData\Local\ESRI\conda\envs\arcgispro-py3-clone_zvbn_02\lib\site-packages\tornado\gen.py", line 742, in run yielded = self.gen.throw(*exc_info) # type: ignore File "C:\Users\xxxx\AppData\Local\ESRI\conda\envs\arcgispro-py3-clone_zvbn_02\lib\site-packages\notebook\services\sessions\handlers.py", line 72, in post type=mtype)) File "C:\Users\xxxx\AppData\Local\ESRI\conda\envs\arcgispro-py3-clone_zvbn_02\lib\site-packages\tornado\gen.py", line 735, in run value = future.result() File "C:\Users\xxxx\AppData\Local\ESRI\conda\envs\arcgispro-py3-clone_zvbn_02\lib\site-packages\tornado\gen.py", line 742, in run yielded = self.gen.throw(*exc_info) # type: ignore File "C:\Users\xxxx\AppData\Local\ESRI\conda\envs\arcgispro-py3-clone_zvbn_02\lib\site-packages\notebook\services\sessions\sessionmanager.py", line 88, in create_session kernel_id = yield self.start_kernel_for_session(session_id, path, name, type, kernel_name) File "C:\Users\xxxx\AppData\Local\ESRI\conda\envs\arcgispro-py3-clone_zvbn_02\lib\site-packages\tornado\gen.py", line 735, in run value = future.result() File "C:\Users\xxxx\AppData\Local\ESRI\conda\envs\arcgispro-py3-clone_zvbn_02\lib\site-packages\tornado\gen.py", line 742, in run yielded = self.gen.throw(*exc_info) # type: ignore File "C:\Users\xxxx\AppData\Local\ESRI\conda\envs\arcgispro-py3-clone_zvbn_02\lib\site-packages\notebook\services\sessions\sessionmanager.py", line 101, in start_kernel_for_session self.kernel_manager.start_kernel(path=kernel_path, kernel_name=kernel_name) File "C:\Users\xxxx\AppData\Local\ESRI\conda\envs\arcgispro-py3-clone_zvbn_02\lib\site-packages\tornado\gen.py", line 735, in run value = future.result() File "C:\Users\xxxx\AppData\Local\ESRI\conda\envs\arcgispro-py3-clone_zvbn_02\lib\site-packages\tornado\gen.py", line 209, in wrapper yielded = next(result) File "C:\Users\xxxx\AppData\Local\ESRI\conda\envs\arcgispro-py3-clone_zvbn_02\lib\site-packages\notebook\services\kernels\kernelmanager.py", line 168, in start_kernel super(MappingKernelManager, self).start_kernel(**kwargs) File "C:\Users\xxxx\AppData\Local\ESRI\conda\envs\arcgispro-py3-clone_zvbn_02\lib\site-packages\jupyter_client\multikernelmanager.py", line 110, in start_kernel km.start_kernel(**kwargs) File "C:\Users\xxxx\AppData\Local\ESRI\conda\envs\arcgispro-py3-clone_zvbn_02\lib\site-packages\jupyter_client\manager.py", line 240, in start_kernel self.write_connection_file() File "C:\Users\xxxx\AppData\Local\ESRI\conda\envs\arcgispro-py3-clone_zvbn_02\lib\site-packages\jupyter_client\connect.py", line 547, in write_connection_file kernel_name=self.kernel_name File "C:\Users\xxxx\AppData\Local\ESRI\conda\envs\arcgispro-py3-clone_zvbn_02\lib\site-packages\jupyter_client\connect.py", line 212, in write_connection_file with secure_write(fname) as f: File "C:\Users\xxxx\AppData\Local\ESRI\conda\envs\arcgispro-py3-clone_zvbn_02\lib\contextlib.py", line 81, in __enter__ return next(self.gen) File "C:\Users\xxxx\AppData\Local\ESRI\conda\envs\arcgispro-py3-clone_zvbn_02\lib\site-packages\jupyter_client\connect.py", line 102, in secure_write with os.fdopen(os.open(fname, open_flag, 0o600), mode) as f: PermissionError: [Errno 13] Permission denied: 'C:\\Users\\xxxx\\AppData\\Roaming\\jupyter\\runtime\\kernel-9fe63dbc-8b8d-4bc1-98f9-1e8536e166bd.json' The permission error at the end looks strange to me, because it is my user folder. Any ideas? Thanks Tim

Hi, after a long time, I have done some further work on the problem. The approach with calculating the service time from the wait time works. So you can do some scenario with different values for the MaxViolationTime. This can give some hints where you have bad connections between trips (Bus A arrives at 12:01 at Stop A, Bus B leaves at 12:00 at Stop A) or where you can create better connection between trips by extending the time between trips. At the end you will probably have a lower number of vehicles or a better vehicle utilisation. If someone is interested I can explain the procedure more in detail. Tim

Hi is the tool already tested with 10.3?

‎09-30-2014

You have to fill in a value for the name field for each Network source in the Network Directions Properties

‎07-21-2014

You can remove spaces by calculating the field and using the rtrim()-function.

"In your current solution, the vehicle has to fulfill one paired orders (a trip) before starting the next one. Therefore, the transit time for the paired orders is the shortest time between the first and second order in the pair. You can use the current transit time as the MaxTransitTime, which essentially is like a fixed transit time in this case." Because I simplify the public transport network it's not only the travel between the order pairs. I removed all intermediate stops so the travel time between the order pairs is much shorter than the real travel time of the trip. So I use the restricted time windows to model the real travel time. The picture shows the route in reality with a lot of deviations, so when I model only the first and the last stop I will create a shorter route on the direct connection. A possibility would be to model all intermediate stops but this would take a lot of effort, and I had to put a lot more data in the model. [ATTACH=CONFIG]22149[/ATTACH] One result of this simplified bus routing and the hard restrictions is that the busses spend a lot on waiting time: [ATTACH=CONFIG]22152[/ATTACH] "In addition, please make sure the MaxViolationTime1 and MaxViolationTime2 are set to null for all orders so all time windows are soft restrictions. In the layer advanced settings, please choose the time window violations importance to low so there will be less penalty for time window violations. If you are free to set any time windows for those trips, I think you can remove all time windows to solve it. Solver will return you a lower cost solution with potentially less vehicles." I think I have to use hard restrictions because it's mainly school transport I model. We have some regulations that the whole travelling time (walking time to stop, time in the bus, waiting time at school before the class begins) is limited e.g. to 80 minutes and the start of school is fixed (is this scenario). I think I do something with the VRP for which the tool wasn't made for, and I want to do a little more. Update: Probably a solution would be to add the waiting time which results from the strict time windows as a service time in the first or last stop of the order pair. Afterwards I can open the time window to model some scenarios.

I already modelled a vehicle schedule based on a given public transport timetable. - I modelled all starts / ends of the timetable trip as orders with TimeWindowStart1 = TimeWindowEnd1 and DeliveryQuantities = 1 for the end and PickupQuantities = 1 for the start - all routes / vehicles have the capacity 1 - I set the start of trip as the FirstOrderName and the end of the trip as the secondOrderName in the Table OrderPairs And the end I get the number of vehicle to fulfill the given timetable and some figures like non-productive times/kilometers. In the next step I want to vary the start/end time of each trip, but I want to keep the travel time of each trip (it's not possible/ too much effort to model the travel time with each stop / stopping time). The aim is to check if there a solution with less vehicles, if I vary stop/end time of the trips a little bit. So my question: Is there a way to give each order pair (public transport trip) a fixed transit time? At the moment the order pairs only offer the parameter MaxTransitTime
