I have similar problem. It worked well last year with ArcGIS10.0 for 300 fields for iteration, but the locking scheme stop my process after a half of the all fileds in ArcGis10.1. How can i unlock it during iterations? thanks, eunsu

Yeh....2TB hard disk space and 12GB memory. I read an article from ESRI website that ArcMap just can handle 4GB memory in max. I was running the network dataset with around 1.5 million segments. I have reduced the number of segments for my analysis significantly and have fast running. However, I still need all the detailed network segments. For certain locations, I cannot set up cut-off because I need to use all the segments.

When you generate a new impedance field, you may use some standard names, such as miles, hour, minutes, meters, and so on. It might help you to set up impedance since the network analyst realize them automatically while setting up parameters of the network analyst.

There is a simple way to use driving time as impedance for network anslyst. start EDIT in the editor extension tool bar. 1. add a new field of [miles] in the table, if you do not have this information. 2. add a new field of [speed] in the table, which is mile per hour in this case. The values of miles and speed should be in the table. 3. add new field of [hour] in the table. 4. calculate travel time by right-clicking on the [hour] field head and select [calculate...] 5. write formulation in the query windows as "[miles]/[speed]" 6. When you set up the network analyst parameter, select [hour] as impedance
