More and more computer simulations of urban traffic are employed in order to predict and optimize the behavior and impact of new technologies. Innovative technologies appear every day and the simulation tools must adapt to take them into account. This thesis shows how custom braking systems can be employed in simulations with the SUMO simulator, something that is currently not supported. A method to make this possible will be provided as well as an assessment of its performance. Not only will this enable future research but it will allow to transport past researches into the present.
