Variable speed limit (VSL) control of highway traffic is expected to improve traffic mobility,
safety, and environment, especially during incidents. However, most existing VSL controllers …

The vast majority of Variable Speed Limit (VSL) control strategies developed in the literature
are based on the well-known macroscopic Cell Transmission Model (CTM), where the traffic …

Integrated variable speed limit and ramp metering control for highway traffic is expected to
smooth the traffic flow and improve the mobility of highway networks. Our recent results …

Urban traffic emissions have been increasing in recent years. To reverse that trend,
restrictive traffic measures can be implemented to complement national policies. We have …

A sudden lane drop on a freeway with high volume of vehicles can cause severe traffic
congestion and safety issues. Forced lane changes near the bottleneck reduce the traffic …

Freeway and arterial transportation networks are operated individually in most cities
nowadays. The lack of coordination between the two increases the severity of traffic …

Ahstract-Different types of variable speed limit (VSL) controllers have been proposed to
improve the traffic mobility at highway bottlenecks. However, the benefit of VSL is sometimes …

Several efforts have been made during recent years on the control of traffic flow using ramp
metering, variable speed limit and lane change control. Most of these techniques reported …

Freeway and arterial transportation networks in most districts are managed separately
without any coordination. This lack of coordination increases the severity of traffic congestion …

Traffic congestion is a major source of inefficiencies in metropolitan freeways (eg
productivity loss, energy waste, pollutant emissions, among other externalities). Active traffic …
