Long-term/Macroscopic level

1. • The ''big picture''​

   • Aggregated traffic flow representation

   • Land-use modelling

   • Time-scale in the range of days to months to years 

2. Mid-term/Mesoscopic level

   • An ''intermediate'' between macro and microscopic simulation​

   • Individual daily travel patterns and decisions (activities scheduling flow estimation and in-day decisions)

   • Vehicles packed in packages-platoons or individual vehicle modelling with simplified flow dynamics

   • Time-scale in range of second to minutes

   • Faster simulation than micro

3. Short-term/Microscopic level

   • ''Physical'' modelling of objects and their dimensions like vehicles, traffic lights, sensors etc.​

   • Disaggregated and detailed representation of users' decision, vehicle movements and and their interactions (car-following, lane changing, gap acceptance etc.)

   • Evaluation of traffic management system designs, traveler information systems, public transport operations, and various ITS strategies at the operational level

   • Energy consumption and emission models

   • High spatial and temporal resolution in range from tenth of a second to seconds

​

In MaaSLab, we focus on developing state-of-the-art methodologies and tools to understand and quantify the complex interactions between supply and demand, using agent-based approaches for multi-scale and multi-modal traffic simulation. In addition to that, we are looking in expanding our research further and incorporate freight models in order to capture the daily and monthly freight demand patterns and identify the impact of commodities movements in the network.
