System Efficiency: Intensity of Congestion (Travel Time Index) (Objective Category)
This objective focuses on managing the intensity of traffic congestion experienced by the traveling public. Congestion is measured using a travel time index, which compares travel conditions in the peak period to travel conditions during free-flow or posted speed limit conditions. For instance, a travel time index of 1.30 indicates that it typically takes 30 percent longer in the peak period than during the off-peak period. The objectives focus on the actual experience of travelers and can be multimodal if transit travel time is included in the measure.Associated Objectives and Performance Measures
