- vehicle angle is not taken into account to determine road space occupancy - using the default model, each vehicle will only ever block one lane so you need to use 'dummy' vehicles to close additional lanes - if a long vehicle is stopped on an intersection it will block cross-traffic according to it's length - using the sublane model, a vehicle may close multiple lanes. Partial blockage is also possible so that a motorcycle can squeeze through will a passenger car cannot. Since the vehicle angle is not taken into account you have to artificially increase the vehicle width to block a wider area. Even a wide vehicle can block at most two lanes fully. Using the sublane modle comes at a price in execution speed. See https://sumo.dlr.de/wiki/Simulation/SublaneModel
