Study of Traffic Conditions in the Victor Emmanuel Roundabout, through the use of simulations

As part of a greater project to alleviate the traffic congestion along the Fawzi Moaz arterial road astudy of the Victor Emmanuel roundabout was conducted. The study has as a goal to increasecapacity and decrease congestion in the Victor Emmanuel roundabout. To do this a data wascollected, analysed, and used to create two models. One in PTV Vissim and one in trafficwaresSynchro 10 with the simtraffic application. Two scenarios where developed, one where theroundabout is signalized, and one where the roundabout is redeveloped into a flower roundabout,where the right turns are separated from the main circulating traffic. During the model developmentissues with missing information had to be address with the help of an iterative fitting process tomodel the route choices made inside the roundabout. The models where then calibrated to considerlocal conditions such as driver behaviour. No direct conclusions could be drawn from the simulationsas the results gave way for multiple interpretations, but the results are that neither of the twotested scenarios gave a clear advantage over the do-nothing scenario. This as the traffic flow anddelay data for both of the develop scenarios where less than in the do-nothing scenario for all exceptone movemen
