We consider the problem of estimating queuelengths at an intersection from a pair of advance and stop bar detectors that count vehicles, when these measurements are noisy and biased. The key assumption is that the stop bar measurement reveals whether the queue is empty or not. We propose a realtime queue estimation algorithm based on stochastic gradient descent. The algorithm provably learns the detector bias, and efficiently estimates the queue-length with theoretical guarantee. The algorithm…

TLDR
Two queue spillback detection methods based on connected vehicle (CV) or probe data based on a kinematic wave theory of traffic and an alternative signal control strategy to mitigate queue spillbacks are presented.

TLDR
A method to estimate queue profiles that are traffic shockwave polygons in the time-space plane describing the spatiotemporal formation and dissipation of queues is proposed, applicable in oversaturated conditions and includes queue spillover identification.
Identification and Analysis of Queue Spillovers in City Street Networks
TLDR
The application of the methodology on an arterial site and the comparison with field data show that it consistently identifies spillovers in urban networks with signal-controlled intersections and the method is extended to account for the variations in vehicle lengths.

TLDR
This study proposes a stochastic queue model considering the strong interdependence relations between adjacent intersections using the probability generating function as a mathematical tool for analyzing the delay and queues of signalized networks under different congestion levels.
Analysis of Queue Estimation Methods Using Wireless Magnetic Sensors
TLDR
Four queue estimation methodologies were studied with wireless magnetic sensors installed on a single-lane loop on-ramp with deficiencies that needed to be taken into account and compensated for if they were to be used for applications that involved ramp metering with accurate queue control.
