TOPL is a suite of tools to specify operational improvements including ramp metering, incident and demand management, auxiliary lanes, traveler information, and to quickly estimate the benefits that such improvements can realize. TOPL is based on the macroscopic cell transmission model (CTM). Advances under TOPL2 can be classified under (1) theory, (2) software and algorithms, and (3) applicati...

A method based on disturbance estimation and bounded controls is proposed to reduce congestion in highways where on-ramp metering can be implemented. An existing model is first extended to account for friction and other interactions between the mainstream and the on-ramp flows. A local variable structure observer is then proposed to estimate the lumped upstream and downstream flows that affect ...

This paper discusses a number of research areas concerned with dynamic traffic management, including forecasting, simulation and, ultimately, control of motorway traffic flow. A detailed non-linear simulation of the Amsterdam A10 west ring road, utilising a dynamic state space representation called the Statistical Traffic Model (STM) is described. The simulation is employed in the development o...

In this paper, congestion dynamics along crowded freeway corridors are modeled as a conservation law with a source term that is continuous in space. The source term represents the net inflow from ramps, postulated here as a location-dependent function of the demand for entering and exiting the corridor. Demands are assumed time-independent, which is appropriate for understanding the onset of co...

The ever-increasing demand for transportation of people and goods as well the massive accumulation population in urban centers have increased need appropriate infrastructure system development order to efficiently manage constantly increasing diverse traffic flows. Moreover, given rapid growth evolution Information Communication Technologies (ICT), intelligent management systems that go beyond ...
