This paper presents an arterial signal optimization model that features its effectiveness on: (1) explicitly modeling physical queue evolution on arterial links by lane-group to account for shared-lane traffic interactions; and (2) capturing the dynamic interactions of spillback queues among lane groups and between neighboring intersections due to high

A link partitioning approach for real-time control of queue spillbacks on congested arterials
Transportmetrica B: Transport Dynamics, 2016ABSTRACTIn oversaturated urban traffic conditions when traffic demand exceeds capacity at signalised intersections, queues fail to clear during the allocated green times. Once a queue reaches the upstream intersection in an arterial, a queue spillback occurs that reduces the upstream link capacity.

Congestion downstream of a freeway off-ramp often produces a traffic queue at the mainline and thus reduces the freeway capacity at the interchange area. To prevent such queue spillback, a proposed real-time control strategy provides a priority signal control to the off-ramp traffic when potential queue spillback is detected.

This paper proposes a link-based continuous-time dynamic user equilibrium model for networks with single destinations. The model captures realistic queue spillbacks by applying the double-queue concept at the link level and developing a new nodal model that extends the link-level dynamics to the network level.

Urban expressways connect with local surface/arterial roads tightly through off-ramps, then lead to the increased traffic volume during peak hours, traffic flows near off-ramps usually become chaotic. Therefore traffic flow behavior at off-ramps is critical to improve traffic management of urban expressways with better analysis.

Transportation Research Part B: Methodological, 2012
The knowledge of path marginal cost (PMC) is central to system-optimal dynamic traffic assignment (SO-DTA) problems. In this paper, we propose a method to approximate PMC in general networks when traffic dynamics are modeled by either the point-queue or the kinematic wave traffic flow model.

Transportation Research Record: Journal of the Transportation Research Board, 2011
In dynamic network traffic loading models with queues spilling back in the links, if one or more links departing a node have demand exceeding capacity, a node model is required to unambiguously constrain the flows exiting the links approaching that node. Basic principles of traffic flow and causality impose requirements on macroscopic node models that

Quasi-dynamic traffic assignment: static traffic assignment with queueing and spillback
2012Historical traffic patterns can be used for the prediction of traffic flows, as input for macroscopic traffic models, for the imputation of missing or erroneous data and as a basis for traffic management scenarios. This paper investigates the determination of historical traffic patterns by means of Ward’s hierarchical clustering procedure.

"Adaptive signal control for reducing the effect of queue spillback"
Urban traffic congestion at signalized intersections poses significant challenges, with queue spillback events worsening delays, fuel consumption, and environmental impacts. This study addresses the critical issue of oversaturation at the Rama 4 intersection in Bangkok, where closely spaced intersections intensify congestion, leading to prolonged ...openaire +1 more source
