Each of those types of vehicles, means a diferent time to pass a intersection or node, and a different speed.</SPAN><BR /><BR /><SPAN>foot</SPAN><BR /><SPAN>speed - 4km/h</SPAN><BR /><SPAN>time need to pass obstacle A -&nbsp; 30s</SPAN><BR /><BR /><SPAN>car</SPAN><BR /><SPAN>speed - 40km/h</SPAN><BR /><SPAN>time need to pass obstacle A - 2 min</SPAN><BR /><BR /><SPAN>truck</SPAN><BR /><SPAN>speed - 30km/h</SPAN><BR /><SPAN>time need to pass obstacle A -&nbsp;&nbsp; -1 min</SPAN><BR /><BR /><SPAN>van</SPAN><BR /><SPAN>speed - 35 km/h</SPAN><BR /><SPAN>speed - 40km/h</SPAN><BR /><SPAN>time need to pass obstacle A - 3 min</SPAN></BODY></HTML> Wed, 01 Sep 2010 10:20:13 GMT https://community.esri.com/t5/arcgis-network-analyst-questions/best-approach-network-with-diferent-class-of/m-p/72229#M707 Igordel_Rio 2010-09-01T10:20:13Z Re: best approach - network with diferent class of vehicles https://community.esri.com/t5/arcgis-network-analyst-questions/best-approach-network-with-diferent-class-of/m-p/72230#M708 <HTML><HEAD></HEAD><BODY><SPAN>There are a couple of options here:</SPAN><BR /><OL><BR /><LI>Create a different cost attribute for each travel mode (based on their respective speeds, etc.).
