New Dilemma Zone Mitigation Strategies
… the right decision and can place them in the dilemma zone. Advance warning systems (AWS) have been used to provide information about the downstream traffic signal change prior to approaching the intersection. On the other hand, advance warning systems increase drivers approach speed according …

Stochastic Methods for Dilemma Zone Protection at Signalized Intersections
Dilemma zone (DZ), also called decision zone in other literature, is an area where drivers face an indecisiveness of stopping or crossing at the yellow onset. The DZ issue is a major reason for the crashes at high-speed signalized intersections. As a result, how to prevent approaching vehicles from …

Modelling drivers’ behaviour within the dilemma zone at traffic signal junctions
… traffic light signal under the effect of the dilemma zone where a driver can neither stop safely nor cross and clear the junction before the onset of red. The purpose of building this model is to investigate the effects of various parameters (such as heavy goods vehicles proportion HGVs%, …

Improving Dilemma Zone Protection Control Issues at Signalized Intersection Using a Web-Game
Web games provide a platform for creative instructional activities that can capture the students' attention towards the course. These games can be used to emulate the realistic situations which can be used as effective lab experiments that could give the students a hands-on experience using real …

Car Following and Dynamic Dilemma Zone Model for Determining Gate Operation Times Based on Driver Behavior at Highway-Rail Intersections
… speed profiles are examined in the approach zone, stopping distance zone, and the track zone for single vehicles as well as platoons of vehicles. A simulation model incorporating the field data, determination of a dynamic dilemma zone, and algorithms to determine gate operation times is …

Study of Bus Driver Behavior at the Onset of Yellow Traffic Signal Indication for the Design of Yellow Time Durations
… are currently calculated to accommodate for dilemma zone protection for passenger cars only. Buses with different vehicle, driver, and occupancy characteristics behave differently at the onset of a yellow indication. The research presented in this thesis characterizes the difference between …

Study of Truck Driver Behavior at Onset of Yellow Traffic Signal Indication for the Design of Yellow Times
… durations are currently calculated to provide dilemma zone protection for passenger cars. Due to differences in vehicle characteristics and driver characteristics, heavy trucks such as tractor-trailers behave differently at the onset of a yellow-indication. The research presented in this thesis …

Statistical and Behavioral Modeling of Driver Behavior on Signalized Intersection Approaches
… with the risk of vehicle crashes resulting from dilemma-zone and red-light-running problems. Such risk of vehicle crashes is greater for high-speed signalized intersection approaches. The research presented in this dissertation develops statistical as well as behavioral frameworks for modeling …

Intersection Stopping Behavior as Influenced by Driver State: Implications for Intersection Decision Support Systems
… These distances were located near and within the dilemma zone, a region in which drivers have a difficult time deciding whether to go or to stop. Data collected from in-vehicle sensors was statistically analyzed to determine significant effects between driver states, and to investigate point …

Modeling Driver Behavior at Signalized Intersections: Decision Dynamics, Human Learning, and Safety Measures of Real-time Control Systems
… of intersections in which drivers encounter a dilemma to pass through or stop when the yellow light commences is called Dilemma Zone (DZ). Several DZ-protection algorithms and advance signal settings have been developed to accommodate the DZ-related safety concerns. The focus of this study is …

Dynamic Learning and Human Interactions under the Extended Belief-Desire-Intention Framework for Transportation Systems
In recent years, multi-agent traffic simulation has been widely used to accurately evaluate the performance of a road network considering individual and dynamic movements of vehicles under a virtual roadway environment. Given initial traffic demands and road conditions, the simulation is executed …
