Abstract: Existing state-of-the-practice traffic signal timing-optimization programs rely on macroscopic and deterministic models to represent traffic flow, including coordinated actuated traffic signal systems. One distinct shortcoming ...

Abstract: Lane use distribution is a useful factor in understanding the lane-by-lane variations of speed and volume on freeways. The most common lane distribution measure has been traffic volume. However, because travel speed from ...

Abstract: This paper presents a cumulative travel-time responsive (CTR) real-time intersection control algorithm that takes full advantage of connected vehicles (CVs). The potential benefits of the proposed CTR algorithm under varying ...

Abstract: Modern traffic signal control systems provide emergency vehicle preemption (EVP) capabilities using advanced sensors and communication technologies. While EVP strategies have been widely implemented by urban transportation ...

Abstract: To enable the safe and fast formation of connected automated vehicle (CAV) platoons in real-world traffic, a preceding vehicle identification system for mixed traffic (PVIS-mixed) is proposed. PVIS-mixed utilizes the ...

Abstract: To facilitate cooperation among connected automated vehicles (CAVs), such as cooperative platooning or cooperative lane changes in mixed traffic comprising CAVs, connected human-driven vehicles (CHVs), and conventional ...

Abstract: Wireless communication among vehicles and roadside infrastructure, known as connected vehicles, is expected to provide higher-resolution real-time vehicle data, which will allow more effective traffic monitoring and control. ...

Abstract: This paper quantitatively assesses the performance of manual traffic-signal control by comparing its performance with two optimized traffic-signal controls during oversaturated conditions. To simulate manual traffic-signal ...

Abstract: This study evaluated the in-service performance of the InSync adaptive signal control (ASC) system utilizing field data collected from the private sector travel time vendor INRIX. A total of six corridors in Virginia were ...
