1. Framework for Estimating Congestion performance measures : from data collection to reliability analysis: case study of Stockholm
Abstract : For operational and planning purposes it is important to observe and predict the traffic performance of congested urban road links and networks. Congestion can be defined as traffic conditions caused by a downstream bottleneck or excess in travel time from what is incurred during light or free-flow travel conditions. READ MORE

2. Relevance and Reliability of Area-Wide Congestion Performance Measures in Road Networks
Abstract : 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. READ MORE

3. Modelling and Appraisal in Congested Transport Networks
Abstract : Appraisal methodologies for congestion mitigation projects are relatively less well developed compared to methodologies for projects reducing free flow travel times. For instance, static assignment models are incapable of representing the build-up and dissipation of traffic queues, or capturing the experienced crowding caused by uneven on-board passenger loads.

4. Congestion Effects in Transport Modelling and Forecasting
Abstract : Transport investments and policies are increasingly turned towards dealing with transport congestion rather than with shortening the potential free flow travel time. However, appraisal methodologies for projects meant to reduce congestion are relatively less well developed compared to methodologies for projects aiming to reduce travel times. READ MORE

5. Capacity utilisation in short sea shipping
Abstract : Shipping is a capital-intensive industry and is characterised by high fixed costs and economies of scale. Trade imbalances and demand variations, market fluctuations and customer demands for high frequency create a situation where shipping companies tend to operate with a high level of unutilised vessel capacity.
