Bottleneck consists of several consecutive segments which are congested at the same time. Several bottlenecks are predefined according to the previous performance evaluation and field observation. The FAST Dashboard uses the same dashboard as the Corridor Dashboard. Please refer Corridor Dashboard Help for usage.
Normally, the Bottleneck Dashboard shows lower speeds and wider 15th and 85th percentile speed range which means the bottlenecks are more congested and more unreliable.
You may also observe the big difference from the AM and PM Peak plots due to the very obvious directional traffic because the CBD area is in the center of the Las Vegas Metropolitan Area.
