Mitigating Bus Bunching with Reinforcement Learning Enhanced by Semantic Stop Embedding
Xin Dong, Vikash V. Gayah
Bus bunching degrades service regularity and increases passenger waiting in high-frequency transit. Existing reinforcement-learning-based holding controllers primarily rely on inst…
Profit-Aware Graph Framework for Cross-Platform Ride-Sharing: Analyzing Allocation Mechanisms and Efficiency Gains
Xin Dong, Jose Ventura, Vikash V. Gayah
Ride-hailing platforms (e.g., Uber, Lyft) have transformed urban mobility by enabling ride-sharing, which holds considerable promise for reducing both travel costs and total vehicl…
A CAV-based perimeter-free regional traffic control strategy utilizing existing parking infrastructure
Hao Liu, Vikash V. Gayah
This paper proposes a novel perimeter-free regional traffic management strategy for networks under a connected and autonomous vehicle (CAV) environment. The proposed strategy requi…
C-MP: A decentralized adaptive-coordinated traffic signal control using the Max Pressure framework
Tanveer Ahmed, Hao Liu, Vikash V. Gayah
Coordinated traffic signals seek to provide uninterrupted flow through a series of closely spaced intersections, typically using pre-defined fixed signal timings and offsets. Adapt…
A Max Pressure Algorithm for Traffic Signals Considering Pedestrian Queues
Hao Liu, Vikash V. Gayah, Michael Levin
This paper proposes a novel max-pressure (MP) algorithm that incorporates pedestrian traffic into the MP control architecture. Pedestrians are modeled as being included in one of t…
OCC-MP: A Max-Pressure framework to prioritize transit and high occupancy vehicles
Tanveer Ahmed, Hao Liu, Vikash V. Gayah
Max-pressure (MP) is a decentralized adaptive traffic signal control approach that has been shown to maximize throughput for private vehicles. However, MP-based signal control algo…
Scale Effects in Ridesplitting: A Case Study of the City of Chicago
Hao Liu, Saipraneeth Devunuri, Lewis Lehe +1
Ridesplitting -- a type of ride-hailing in which riders share vehicles with other riders -- has become a common travel mode in some major cities. This type of shared ride option is…
A Novel Max Pressure Algorithm Based on Traffic Delay
Hao Liu, Vikash V. Gayah
This paper considers a novel travel-delay-based Max Pressure algorithm for control of arbitrary transportation networks with signalized intersections. The traditional number-of-veh…
A Survey on Traffic Signal Control Methods
Hua Wei, Guanjie Zheng, Vikash Gayah +1
Traffic signal control is an important and challenging real-world problem, which aims to minimize the travel time of vehicles by coordinating their movements at the road intersecti…
Analysis of traffic statics and dynamics in a signalized double-ring network: A Poincaré map approach
Qi-Jian Gan, Wen-Long Jin, Vikash V. Gayah
Understanding traffic statics and dynamics in urban networks is critical to develop effective control and management strategies. In this paper, we provide a novel approach to study…
On the Continuum Approximation of the On-and-off Signal Control on Dynamic Traffic Networks
Ke Han, Vikash Gayah, Benedetto Piccoli +2
In the modeling of traffic networks, a signalized junction is typically treated using a binary variable to model the on-and-off nature of signal operation. While accurate, the use…
A robust optimization approach for dynamic traffic signal control with emission considerations
Ke Han, Hongcheng Liu, Vikash Gayah +2
We consider an analytical signal control problem on a signalized network whose traffic flow dynamic is described by the Lighthill-Whitham-Richards (LWR) model (Lighthill and Whitha…
