Hello, I have a network in which I want to account for left turns from local streets to arterial streets. I want to assign a significant delay (e.g., 30 seconds). The problem is, I want to model pedestrian travel time, so I don't want to favor travel along arterial roads. I've turned the hierarchy attribute off in my analysis layer and I'm having problems determining whether this has solved my problem. Does anyone have any insight or proposed alternative solutions? Thanks in advance, Kim

I've created a network data set to that utilizes hierarchy to assign and global turn delay to assign a severe penalty to crossing unsignalized arterial roadway crossings. The intent was to assign a high value and set the cutoff value well below the threshold. In testing the network, I've determined that cost is accumulating as expected, but network analyst is finding routes with a much higher cost value than I've specified in the analysis settings. I should note that I used the Global Turn Delay calculator to set my turn delay very high for local roadways crossing arterials. Network analyst will not 'solve' when the cutoff is lower than 150. However, when I use any higher value the time accumulation is well above the threshold (about 5,000) which is the value I assigned to the intersections. Coincidentally, the points are about 150 M apart. I'm wondering if I've set the evaluators incorrectly? Screenshot attached.

Hello, I've created a model that solves closest facility within a given corridor. I can successfully process a single corridor, but get an error reading 000840, not a shapefile when trying to process multiple corridors within the same model run. The problem seems to be with the batch processing rather than the model itself, but any thoughts would be greatly appreciated.

I'm trying to export a series of shapefiles to CAD. I've completed this exercise successfully in the past, but I'm trying unsuccessfully. I've tried both polyline and polygon files containing about 20,000 features. If I reduce the number to 100 - 1000 the conversion is successful. Starting the conversion typically results in an failure around minute 3. Attempted conversion to DXF as opposed to DWG results in an empty file. Any thoughts or recommendations would be welcome. Thanks, Kim
