Congestion Indicators and Congestion Impacts: A Study on the Relevance of Area-wide Indicators

Abstract [en]

Congestion indicators for monitoring congestion in road area networks have been devised to use the output of long-term planning models which makes them insensitive to the dynamics of congestion or pollutant emissions. The objective of the present study is to compare the capabilities of different congestion indicators for describing congestion impacts (delays and emissions) considering a dynamic framework analysis. Microsimulation is used for estimating the congestion indicators as well as the congestion impacts in a disaggregated and dynamic mode. The indicators with the best descriptive capabilities are identified. Recommendations about indicators are provided for road practitioners.

Abstract [en]

For operational and planning purposes it is important to observe, predict and monitor the traffic performance of congested urban road links and networks. This monitoring effort describes the traffic conditions in road networks using congestion performance measures. The objective of this research is to analyse and evaluate methods for measuring congestion and congestion performance measures for monitoring purposes. For this objective, a selection of the required aspects of the performance measures in the literature is considered. The aspects to be considered can be classified into two categories: A first group relates to the statistical aspects of these indicators, i.e. reliability. The second relates to their ability to capture the impacts of congestion, i.e .relevance. The reliability and relevance of the congestion performance measures are evaluated. A recommendation of the most suitable indicator is provided at the end of the study.
