-The MAS source code is used as the basis for a new Vehicle Agent System (VAS) module in order to couple MATSim output data (i.e. emissions and movement paths) to PALM-4U. For this, a new coupler MATSim-PALM-4U was created to read the movement paths and traffic emissions of the vehicles from MATSim output and incorporated them into the PALM-4U. Since the time step of the vehicles from MATSim output files (1 second) is larger than the model time step of PALM-4U, the new module of VAS will contain an interpolation/accumulation procedure of the vehicles' emissions for each grid cell of PALM-4U.
-The interpolation algorithm computes each cell visited by the moving vehicles within the PALM-4U grid and then calculates the fraction of time the vehicles spent in each grid cell. Based on this time fraction, the vehicles' emissions are updated on every grid cell visited by the vehicles.

 The algorithm also treats some special cases, when the vehicles are moving exactly on the grid lines (horizontal or vertical) and on the edges of the domain. There are some assumptions/modifications to the algorithm, such that:

-Also, the pedestrians' movements from MATSim output have been taken into account in the new interface: each initial and target position of the pedestrians, and starting and ending time of the movements of the agents were incorporated in PALM-4U. Then the main model runs the MAS with the new agents for the given simulation time.
