ABSTRACT 1 Dynamic speed limits (DSL) strategies are expected to delay onset of
congestion thanks to its 2 ability to improve traffic flow homogenization and its mainstream …

Capacity drop at congested freeway bottlenecks is well known with a lot of field
observations. This paper studies coordinated ramp metering (RM) and mainstream traffic …

Variable speed limit (VSL) and ramp metering (RM) affect freeway traffic operations in
different ways and, accordingly, result in different effects on system travel time. The primary …

The paper proposes a multi-class control scheme for freeway traffic networks. This control
scheme combines two control strategies, ie ramp metering and route guidance, in order to …

Throughout the past three decades, various versions of the the cell-transmission model
(CTM) has been proposed. In spite of the increased attention to freeway traffic modelling via …

An accurate density monitoring along a stretch of a freeway, especially under congested
time-variant conditions is necessary to evaluate congestion levels, understand complex …

For the last decades, congestion on highways has been a serious issue. Congestion causes
more air pollution, accidents and delays, resulting in late arrival for employment or meetings …

Aiming at operating effectively future traffic systems, we propose here a novel methodology
for integrated lane-changing and ramp metering control that exploits the presence of …

The paper characterizes the behavior of the cell transmission model of a freeway, divided
into N sections or cells, each with one on-ramp and one off-ramp. The state of the dynamical …

Ramp metering (RM) and variable speed limits (VSLs) affect freeway traffic in different ways
and, accordingly, result in different effects on travel time and crash risk. This study compared …
