Congestion Management Monitoring |
Auto vehicle occupancy is calculated by counting passenger cars at a given location and the number of people in each vehicle. The number of people divided by the number of cars is the auto vehicle occupancy for that location. Auto vehicle occupancy information has been collected at twenty locations (15 in 1999 and 5 in 2000) throughout the Clark County area. Data was collected for freeways and arterials during the AM, PM, and midday time periods.
In the PM peak, SR-14, I-205 and I-5 south of Main Street have the lowest average vehicle occupancy rates (1.12 to 1.18). The two east/west arterials, Fourth Plain and Mill Plain have the highest average vehicle occupancy rates possibly due to a higher percentage of non-commute trips. The PM time period has a higher auto occupancy rate, likely due to a greater percentage of discretionary trips such as shopping where drive alone trips are less prominent.
