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.

Since the mapping between objectives and service packages is not always straight-forward and often situation-dependent, these mappings should only be used as a starting point. Users should do their own analysis to identify the best service packages for their region.
