Hi Jay, you are right. I have not re-built the dataset. But the problem regarding attribute table is that I have created separate shape file for each type of road. And I sent you only local roads attribute table by mistake.. Now I'm sending you all the attribute tables for all the layers.. Regarding connectivity model you suggest that if I would have to maintain these two classes I have to create junction feature class.. for that I have to refer Paris data.. But the problem is I didn't got any idea from Paris data.. since I make the connectivity model again.. Please check is it correct or not..?? Also I have send you snapshot of the evaluator settings for attributes (hierarchy, Minutes, restrictions.). Please check is that correct or not..?? My requirement is only local and minor roads should be traversable. and the speed on local roads should be 0.75meter /second and for minor roads it is 1meter/second. Therefore I derive the field minutes = length/0.75 for local roads and minutes = length/ 1 for minor roads. So is that equation correct..?? Another Problem is how to create turn features in th network dataset..?? For that Should I digitize each and every turn in the shape files separately..?? Or is there any quick method that way I can create turn feature class and bring that in my network dataset..?? Thanks.. Ramk

Thanks Jay, your right. i want to make 1 min service area polygon. but why they don't go along the road instead they cross the the road. I have tried for trim polygon option and line generation option as you suggest. I got some results. but within service area it not generate lines for all lines. some lines are missing. next is though I have given the restriction rule to highways since polygon cross the highways.. why..?? again i send you some slides of my network dataset properties and attribute table. kindly check those slides. suggest me if there is any correction in attribute table or network dataset.. Thanks and Regards Ramk

Hi.... I am working with ArcGIS 9.2 network analysis.. Building network dataset is finished but the results of service area polygons are seems incorrect. i am not sure whether they are correct or not.? first i face the problem regarding how to define walking speed, restrictions and left turn/right turns with different seed.. some how i manage the walking speed and restrictions but turns problem is remaining. I have attached the snapshots of my results of service area polygons and attribute table as well.. Please check those slides and suggest me if any correction is there.. Reply Asap. Thanks....
