Despite the continuous advances in the fields of control and computing, the design and deployment of an efficient Large-scale Nonlinear Traffic Control System (LNTCS) remains a significant objective. This is mainly due to the complexity and the strong nonlinearities involved in the modeling of traffic flow processes. Practical control design approaches are often based on simplified models about...

Although transit or road capacity increases are historically very common subjects of economic analysis, the implementations of intelligent transportation systems (ITS) strategies have been receiving increasing attention as resources for capacity expansion become increasingly scarce. There exists a strong business case for lower cost strategies to more efficiently deliver transportation in ways ...

Traffic congestion is a common problem; particularly in metropolitan areas. It is especially true for the Tokyo Metropolitan Freeway (MEX) which handles about 1.2 million vehicles per day. Thirty percent of these vehicles use the MEX central circular and radial routes causing chronic traffic congestion. A traffic-control center in Japan mitigates the congestion by governing access to MEX entran...

Empirical observations and theoretical studies indicate that the overall travel-time of vehicles in a traffic network can be optimized by means of ramp metering control systems. Here, we present an analysis of traffic data of the highway network of North-Rhine-Westfalia in order to identify and characterize the sections of the network which limit the performance, i.e., the bottlenecks. It is cl...

The Highways Agency (HA) is developing the concept of Active Traffic Management (ATM) schemes which will coordinate operational regimes such as controlled use of the hard shoulder as a running lane, variable speed limits and ramp metering. The pilot ATM scheme is planned to be implemented on the eastern section of the M42 between Junctions 3a and 7 by 2006. To ensure the success of all these me...
