Yes, the program has the following attributes: 1. Wide range of vehicular behavior for different types of users, differentiating lane change gaps, following distances, decisions, 2. Reductions or increases in speed due to different geometries of turn radii, pavement conditions and width of traffic lanes, 3. Priority rules for vehicles that are at an intersection point taking or yielding the right-of-way according to the approach distances, and 4. Vehicular congestion due to the accumulation of traffic at intersections, intersection zones, areas of mixed flows, acceleration lanes, and others.
To be more precise and laconic, my point of view was since vissim is a microsimulation software and density and volume are macroscopic characteristics??
