A Model to support stakeholders evaluation of transportation policy options in Las Vegas, Nevada

Document Type

Conference Proceeding


This paper describes a model created through a group model building process conducted to help a stakeholder advisory committee develop policy recommendations for a regional transportation agency. Over seven months, we worked with committee members and the transportation authority’s technical staff to develop the strategic-level model. The model reflects the group’s definition of the problem and collective understanding of the system. The group’s goal was to improve traffic congestion, flow and air quality over a 25-year planning horizon at the lowest system cost. Their final recommendation included a mix of policies with an estimated cost of $2.5 billion that achieved the greatest air quality benefit and significantly reduced congestion and increased flow. Participants were very positive about the model-based process, saying it was faster and less painful than similar processes they had participated in. This paper describes the structure of the model and its use in the stakeholder involvement process.
