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

Abstract

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-beforeleft 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 TraffSim, 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.

Scalable Data Model for Traffic Congestion Avoidance in a Vehicle to Cloud Infrastructure

“…In addition to many works that analyzed and showed the benefits of urban traffic simulation based on TraffSim [ 59 , 60 , 61 , 62 ], an interesting approach for urban traffic prediction and congestion avoidance based on routing algorithms is described in [ 63 ]. They use microscopic traffic simulation of 2000 and 3000 vehicles on artificial and real world maps.…”

Modelling and Simulation of Isolated Traffic Control Strategies in TraffSim

“…AbstractJunction: This entity serves as a base class encapsulating the access logic for vehicles approaching or traversing through the intersection by integrating the generic control scheme outlined in [8]. It maintains a list of road segments and junction connectors for managing inward and outward connections and is capable of obtaining general key figures such as an intersection's throughput.…”

“…Whilst a generic and accident-free intersection control logic for TraffSim has been developed recently [8], it does not allow for a more sophisticated kind of traffic control. Our work addresses this particular issue and focuses on the integration of different traffic control strategies for regulating signalized intersections.…”
