It's well these fields which allow to affect a time of route by section following the speed? </SPAN><BR /><SPAN>If I understood well, FT and TF is the extremities of my sections. </SPAN><BR /><BR /><SPAN>I found an example of calculation: Minutes_ft = (longueur_tronçon / 2/1000 / [speed] 60), this calculation is it correct? </SPAN><BR /><BR /><SPAN>Thank you for your answers.</SPAN></BODY></HTML> Tue, 19 Mar 2013 10:13:03 GMT https://community.esri.com/t5/arcgis-network-analyst-questions/arcgis-10-create-road-graph/m-p/411963#M3882 BenoitGUINARD 2013-03-19T10:13:03Z Re: ArcGIS 10 : Create road graph https://community.esri.com/t5/arcgis-network-analyst-questions/arcgis-10-create-road-graph/m-p/411964#M3883 <HTML><HEAD></HEAD><BODY><SPAN>Hello,</SPAN><BR /><BR /><SPAN>I'm not sure I completely understand your question.
