TraffSim -- A Traffic Simulator for Investigating Benefits Ensuing from Intelligent Traffic Management

Modeling a Continuous and Accident-Free Intersection Control for Vehicular Traffic in TraffSim

“…In traffic simulators supporting dynamic routing such as TraffSim [4], but also FreeSim [1], intersection control must strongly be associated with the routing decisions. Since our intersection control makes its decisions based on the knowledge of source and destination lane of a specific intersection, unbounded changes of the destination can have serious consequences and lead to wrong permissions for vehicles or even accidents.…”

“…TraffSim is an extensible microscopic simulation framework for vehicular traffic and is presented in detail in [4]. In microscopic simulation scenarios, each simulated virtual unit has a corresponding counterpart in the simulation which naturally has to be modelled as close to reality as possible.…”

Modelling and Simulation of Isolated Traffic Control Strategies in TraffSim

“…All simulations conducted in the scope of this work are carried out using the microscopic simulator TraffSim [5] and with the aid of two exemplary scenarios, which are outlined in Figure 4. The first scenario comprises a single four-way intersection made up by an arterial road (two lanes, left and right turners) and a crossing street (single lane, no turn restrictions).…”

“…Simulations are a widespread and often used method to study complex transportation networks and investigate scenarios that cannot be studied in a real experiment or by any other analytical method. In recent years, a variety of simulation frameworks of different types and for diverse use cases has been proposed by researchers in the field [1][2][3][4][5]. Apart from models defining the longitudinal movement or lane-change behaviour of individual vehicles on the road, microscopic traffic simulators require additional components in order to control global limitations which are valid for all vehicles, e.g.…”

“…The simulation framework TraffSim is a microscopic traffic simulator allowing for the time-discrete and statecontinuous simulation of vehicular traffic, supporting a wide range of models and parameters [5]. In such microscopic simulation scenarios, each virtual component has a corresponding equivalent in the simulation which certainly has to be modeled as close to reality as possible.…”
