The traffic congestion problem on urban expressways, especially in the weaving areas, has become severe. Some cooperative methods have been proven to be more effective than a separate approach optimizing state areas expressways. However, method that combines channelization with ramp metering not presented and its effectiveness examined yet. Thus, fill this research gap, study proposes reinforce...

The trend of increasing traffic demand is causing congestion on existing urban roads, including motorways, resulting in a decrease Level Service (LoS) and safety, an increase fuel consumption. Lack space non-compliance with cities’ sustainable plans prevent the expansion new transport infrastructure some areas. To alleviate aforementioned problems, appropriate solutions come from domain Intelli...

This paper proposes a Logic-Based Traffic Flow Control algorithm (LB-TFC) for integrated control of Ramp Metering (RM) installations and Variable Speed Limits (VSLs) in order to reduce traffic jams created at bottlenecks. LB-TFC estimates, each time step, the number vehicles that should be held back or released by measures (i.e. VSLs RM rates) avoid capacity drop (maximizing outflow bottleneck)...

Capacity drop (CD) at overloaded bottlenecks is a puzzling traffic flow phenomenon with some internal and complicated mechanisms the microscopic level. not only important for theory modelling, but also significant control. A model evaluating control measures needs to be able reproduce capacity in order deliver reliable evaluation results. This paper delivers comprehensive overview on subject fr...
