2018 journal article
Comparison of performance between Virtual Controller Interface Device and Controller Interface Device
IET Intelligent Transport Systems, 12(1), 22–30.
author keywords: traffic engineering computing; control engineering computing; user interfaces; telecontrol; intelligent transportation systems; virtual controller interface device; virtual CID; VCID; traffic signal controllers; microsimulation software; National Transportation Communications; ITS Protocol; NTCIP; traffic networks; queue length; travel time; simulation stability; remote control; physical signal control laboratory
TL;DR:
A Virtual CID (VCID) is proposed and results show that VCID could provide accurate and reliable simulation results, and has more advantages as it does not depend on any hardware device and is easy to operate.

2018 journal article
Modeling the Impacts of Traffic Flow Arrival Profiles on Ramp Metering Queues
Transportation Research Record: Journal of the Transportation Research Board, 6, 036119811878225.
TL;DR:
It is revealed that ramp queue length tends to increase linearly with upstream signal cycle length, and the design of queue storage length for a metered on-ramp hence needs to fully consider the various ramp configurations and upstream signal timing settings.

2018 journal article
Queue length estimation for a metered on-ramp using mesoscopic simulation
Transportation Letters, 5, 1–10.
author keywords: Ramp metering; queue length modeling; mesoscopic simulation; demand-to-capacity ratio; queue storage length
TL;DR:
A mesoscopic simulation model for queue length estimation under various demand-to-capacity scenarios showed that the queue length modeling method could properly capture the realistic queue profile, and the estimated queue lengths were close to the field observations.

Distributed optimization and coordination algorithms for dynamic speed optimization of connected and autonomous vehicles in urban street networks
Transportation Research Part C: Emerging Technologies, 95, 497–515.
Contributors: M. Tajalli* & A. Hajbabaie*
TL;DR:
DOCA decomposes the nonlinear network-level speed optimization problem into several sub-network-level nonlinear problems thus, it significantly reduces the problem complexity and ensures scalability and real-time runtime constraints.
