Modeling a continuous and accident-free intersection control for vehicular traffic in TraffSim

With the goal of accomplishing vehicular traffic simulations close to reality, modelling intersection control is a very important issue which affects the traffic flow and hence simulation results considerably. This paper presents an exhaustive intersection control applicable for continuous traffic simulators. Our work contains many types of road crossings and junctions occurring in real road networks, including unregulated intersections without prioritization (right-before-left rule), traffic light controlled ones, intersections regulated with road signs and combinations of them with different numbers of road segments inwards and outwards. Special situations such as route changes before intersections and multilane situations are addressed. The models are implemented for the continuous traffic simulator Traff Sim, which demonstrates their applicability and range of features. With the introduced set of rules and situations, a great majority of intersections of real road networks can be parametrized and simulated virtually and the requirements for traffic flow investigations through dynamic simulations are fulfilled.
