Estimating Reliability and Extent for the Las Vegas Area Congestion Management Systems
This paper presents a Geographic Information Systems (GIS) based methodology to estimate the extent and reliability of congestion using crash data. The crash data are geocoded using the street centerline coverage for the Las Vegas metropolitan area, The number of crashes on each link and the number of occupants involved in these crashes are estimated. Crash rates and average vehicle occupancy (AVO) rates are estimated. The extent is based on the link volumes and the estimated AVO rate from crash data. Reliability is computed based on the number of crashes and link volumes. These are disaggregated by time of the day, road functional class, and the area type.
