I have followed the process specified in arcgis resources exercise 10 for creating traffic network dataset (san diego) and used custom traffic provider (.dll to register GUID) , used the update model provided in exercise 10 to update DTF files in a folder where network dataset is pointed. (TrafficFiles\v1)
and i had scheduled this task (task scheduler) for interval of 15 min .
i am able to get DTF files in folder and can visualize historical data .. but not able to visualize live traffic from DTF files on dataset ( layer properties -> symbology -> live traffic only)
DTF files are saved with timestamp as name, along with feed entry in trafficindex.xml
i had cross checked the result DTF file ... by DTFtoCSV conversion ( its same as input )
1) how does network dataset know that DTF file has been updated? does it check interval based?
2) Why tool saves DTF file saves in a seperate folder (v1) ?
3) while creating network dataset we provide a folder path till v1, where as in update tool till trafficfiles .....
initially the folder is empty.. no xml, no dtf ... how does _ND know update DTF is in v1 folder?
