2 Objectives Overview of intersections configuration methods Overview of related works Identify the most appropriate intersection Analysis of a real intersection configuration method properties Study of travel time and number of vehicles for different intersection configuration methods M ădălin -Dorin Pop / Decision Making in Road Traffic Coordination Methods: A Travel Time Reduction Perspective / EnT-2020
3 In Intersections Confi figuration Meth thods → Uncontrolled In Intersections Configuration • characterized by the lack of traffic signals or signs for traffic flow control; • vehicles flow through these intersections done by applying the priority-to-the-right rule; • this type of configuration method can lead to gridlock if the road network becomes overloaded.

4 In Intersections Confi figuration Meth thods → Sig ignalized In Intersections Coordination - Traffic Li Lights • solves the problem of gridlock mentioned as disadvantage of previous coordination method in case of overloaded road networks; • the reduction of traffic congestion depends on the green intervals setting; • two modes of traffic lights configuration: • based on stop lines; • based on lane connectors.

5 In Intersections Confi figuration Meth thods → Sig ignalized In Intersections Coordination - Traffic Li Lights Base ased on on stop lin lines: • all vehicles from the lanes affected by the red traffic light shall wait for the green light, independent of the direction chosen to leave the intersection; • priority-to-the-right rule applies for left turn.

6 In Intersections Confi figuration Meth thods → Sig ignalized In Intersections Coordination - Traffic Li Lights Base ased on on lan lane connectors: • highlights the possible directions that can be reached, taking into account the current lane of the studied vehicle; • advantage - the additional green time that can be given to the vehicles that are turning right. M ădălin -Dorin Pop / Decision Making in Road Traffic Coordination Methods: A Travel Time Reduction Perspective / EnT-2020
7 In Intersections Confi figuration Meth thods → Roundabouts • one-way circular lanes that have entry points for vehicles coming from several directions; • the movement of vehicles entering a roundabout is conditioned by giving priority to the vehicles already present in the roundabout.

8 Intersections Confi In figuration Meth thods → Agent-Based Modeling – AnyLogic Simulation Environment Symbol Na Name Significance Si Creates the cars and attaches the coordinates according to a CarSource specified location. Car arrivals can be defined using the arrival rate, interarrival rate, etc. Is used for car movement management. The destination can be a stop line, a road, parking place etc. If the movement to a CarMoveTo specified destination is not possible, the car can be routed to a destination specified using port onWayNotFound . CarDispose Eliminates a car from the road network. Controls the movement of vehicles using the stop lines or lane TrafficLight connectors by associating the timing for each color signal. This block ensures the simulation of traffic light behavior. M ădălin -Dorin Pop / Decision Making in Road Traffic Coordination Methods: A Travel Time Reduction Perspective / EnT-2020

13 Conclusions Purp rpose: • identify the most appropriate decision of intersection configuration method based on specific intersection case study. Con ontributions: • overview of related works regarding the intersections configuration methods; • present a case study of real intersection; • show the impact of intersections configuration methods on reducing the travel time, increasing the number of vehicles crossing the road network and, implicitly, reducing traffic congestion.
