A Discrete Control Method for the Unsignalized Intersection Based on Cooperative Grouping
IEEE Transactions on Vehicular Technology, 2022The traditional signalized intersection is no longer able to meet the increasing demands of transportation. A method combining autonomous intersection management (AIM) and connected and automated vehicles (CAVs) is suggested for solving existing traffic ...

Control of autonomous vehicles at an unsignalized intersection
2017 American Control Conference (ACC), 2017Safety and optimal traffic flow are important priorities in intelligent transportation systems. This paper presents a collaborative method for collision avoidance between autonomous vehicles at an unsignalized intersection. The collision conditions are expressed in terms of the vehicles' speed ratios.

Safe Efficient Policy Optimization Algorithm for Unsignalized Intersection Navigation
IEEE/CAA Journal of Automatica SinicaUnsignalized intersections pose a challenge for autonomous vehicles that must decide how to navigate them safely and efficiently. This paper proposes a reinforcement learning (RL) method for autonomous vehicles to navigate unsignalized intersections ...

Application of Effective Transition Covers on Deadlock Control of Unsignalized Intersection Systems
International Conference on Networking, Sensing and ControlVehicle congestion or collision can easily happen at unsignalized intersections if there are no appropriate control policies. In this paper, we mainly focus on special congestions due to vehicle circular waits, i.e., deadlocks.

The New German Guideline for Capacity of Unsignalized Intersections
1991This paper describes the background of a new German guideline for the estimation of the ‘capacity at unsignalized intersections. It contains information on fundamental aspects of the theory as well as a description of the proposed procedure which results from several research projects carried out on behalf of the West German Federal Minister of ...

Assessing motorcyclist safety at unsignalized intersection using automated trajectory data analysis
Traffic Injury PreventionObjective In a developing country like India, where the share of motorcyclists is increasing exponentially, their road crashes are also rising at an alarming rate. The majority of these road crashes occur at unsignalized intersections.

Limited priority merge at unsignalized intersections
Transportation Research Part A: Policy and Practice, 1999Abstract The development of a new gap acceptance model based on limited priority for the major stream is discussed. Field observations were carried out to identify the mechanism of the merging process taking place at unsignalized intersections under congested conditions.

Motorist Yielding to Pedestrians at Unsignalized Intersections
Transportation Research Record: Journal of the Transportation Research Board, 2006This paper evaluates engineering treatments that can be used to improve the safety of pedestrians crossing in marked crosswalks on busy arterial streets. The research team collected extensive data at 42 study sites in different regions of the country to gauge the effectiveness (as measured by motorist yielding or stopping) of various engineering ...

The Design of Unsignalized Intersections in the UK
1988The cost of traffic delays and accidents at road junctions in the UK is estimated at some £6,000M or so per year, and more than 50% of it comes from unsignalised junctions. Design practices, which bear directly upon the efficiency, and therefore the user cost, of junctions have been subject to much scrutiny over the past decade, and the methods now ...

Collaboration and Optimal Conflict Resolution at an Unsignalized Intersection
IEEE Transactions on Intelligent Transportation Systems, 2019Safety and efficiency are important priorities in transportation engineering. The new research directions in intelligent transportation systems focus on autonomy and collaboration to improve safety and efficiency. In this paper, we consider the problem of conflict resolution at an unsignalized intersection.
