Flowchart of WisDOTs lane closure analysis program. There are 14 boxes and two ovals. The two ovals are products that are to be produced. The boxes are decisions that get one to the products. There are five decision points. The first is will work occur on holiday or during special event? The second is Review and Adjust hourly traffic volume data. Is lane closure appropriate per LCS tool? The third is Are there other proposed WZ in same corridor or segment? The fourth is do estimated delays exceed acceptable criteria? The fifth is would other staging or mitigation methods have potential to be cost effective?
