<dc:description xml:lang="en">Summarization: Mainstream Traffic Flow Control (MTFC), enabled via variable
|
||||
speed limits, is a control concept for real-time freeway traffic management. The benefits of MTFC for
|
||||
efficient freeway traffic flow have been demonstrated recently using an optimal control approach and a
|
||||
feedback control approach. In this paper, both control approaches are reviewed and applied to a freeway
|
||||
network in a simulation environment. The validated network model used reflects an actual freeway (a
|
||||
ring-road), fed with actual (measured) demands. The optimal and feedback control results are discussed,
|
||||
compared and demonstrated to improve significantly the system performance. In particular, the feedback
|
||||
control scheme is deemed suitable for immediate practical application as it takes into account operational
|
||||
requirements and constraints, while its results are shown to be satisfactory. In addition, the control
|
||||
system performance was not very sensitive to variations of the parameters of the feedback controller. This
|
||||
result indicates that the burden associated with fine tuning of the controller may be reduced in the field.

<dc:description xml:lang="en">Summarization: This paper describes a novel approach for defining optimal
|
||||
strategies in motorway traffic flow control, considering that a portion of vehicles are equipped with
|
||||
vehicle automation and communication systems. An optimisation problem, formulated as a Quadratic Programming
|
||||
(QP) problem, is developed with the purpose of minimising traffic congestion. The proposed problem is based
|
||||
on a first-order macroscopic traffic flow model able to capture the lane changing and the capacity drop
|
||||
phenomena. An application example demonstrates the achievable improvements in terms of the Total Time Spent
|
||||
if the vehicles travelling on the motorway are influenced by the control actions computed as a solution of
|
||||
the optimisation problem.

<dc:description xml:lang="en">Summarization: The Adaptive Cruise Control (ACC) system, is one of the emerging
|
||||
vehicle technologies that has already been deployed in the market. Although it was designed mainly to
|
||||
enhance driver comfort and passengers’ safety, it also affects the dynamics of traffic flow. For this
|
||||
reason, a strong research interest in the field of modelling and simulation of ACC-equipped vehicles has
|
||||
been increasingly observed in the last years. In this work, previous modelling efforts reported in the
|
||||
literature are reviewed, and some critical aspects to be considered when designing or simulating such
|
||||
systems are discussed. Moreover, the integration of ACC-equipped vehicle simulation in the commercial
|
||||
traffic simulator Aimsun is described; this is subsequently used to run simulations for different
|
||||
penetration rates of ACC-equipped vehicles, different desired time-gap settings and different networks, to
|
||||
assess their impact on traffic flow characteristics.

<dc:description xml:lang="en">Summarization: Mainstream traffic flow control (MTFC) with variable speed limits
|
||||
(VSLs) is a freeway traffic control method that aims to maximize throughput by regulating the mainstream
|
||||
flow upstream from a bottleneck. Previous studies in a macroscopic simulator have shown optimal and feedback
|
||||
MTFC potential to improve traffic conditions. In this paper, local feedback MTFC is applied in microscopic
|
||||
simulation for an on-ramp merge bottleneck. Traffic behavior reveals important aspects that had not been
|
||||
previously captured in macroscopic simulation. Mainly, the more realistic VSL application at specific points
|
||||
instead of along an entire freeway section produces a slower traffic response to speed limit changes. In
|
||||
addition, the nonlinear capacity flow/speed limit relation observed in the microscopic model is more
|
||||
pronounced than what was observed at the macroscopic level. After appropriate modifications in the control
|
||||
law, significant improvements in traffic conditions are obtained.
