What I mean by that is I have a road network with hazards on that network, and I am wondering if it's possible to determine the shortest route through that network while encountering the fewest hazards using built in tools. I don't do network analysis very often, and&nbsp;I'm not 100% sure it can be done in network analyst.</P></BODY></HTML> Thu, 28 Mar 2019 14:07:03 GMT https://community.esri.com/t5/arcgis-network-analyst-questions/weighted-network-analysis/m-p/99324#M995 GrantHaynes 2019-03-28T14:07:03Z Re: Weighted network analysis https://community.esri.com/t5/arcgis-network-analyst-questions/weighted-network-analysis/m-p/99325#M996 <HTML><HEAD></HEAD><BODY><P>Network Analyst supports loading in "barriers".
