Description: Bottleneck Definition:Bottleneck conditions are determined by comparing the current reported speed to the reference speed for each segment of road. Reference speed values are provided to us for each segment and represent the 85th percentile observed speed for all time periods. If the reported speed falls below 60% of the reference, the road segment is flagged as a potential bottleneck. If the reported speed stays below 60% for five minutes, the segment is confirmed as a bottleneck location.Field Descriptions:Rank: From the 'Bottleneck Ranking' tool, all ten segments ranked 1-10, 1 being the largest bottleneck.Impact: The aggregation of queue length over time for congestion originating at each location in mile-minutes. For example, if at time t1 an element has congestion covering one mile of the roadway, it has an impact of 1. If the congestion then grows at time t2 to cover 2 miles, the location will now have an impact of 3. If at time t3 congestion shrinks to 1 mile, and at t4 there is no congestion, the element will have a final impact of 4.Avg_Max_Le: The average maximum length, in miles, of queues formed by congestion originating at the location.Avg_Durati: The average amount of time per day that congestion is identified originating at the location.Total_Dura: The total amount of time congestion was identified at the location.Name: Name of road segment, direction, and nearest exit or crossroad.
