In the modern era, characterized by intense urbanization and frequent travel between interconnected communities, constant expansion of cities, associated with high densities growing need for traveling, has led to a significant increase in road traffic volumes. More than ever, today requires effort be managed effectively order improve performance safety conditions, given greater probability unpl...

Frequent lane-changes in highway merging, diverging, and weaving areas could disrupt traffic flow and, even worse, lead to accidents. In this paper, we propose a simple model for studying bottleneck effects of lane-changing traffic and aggregate traffic dynamics of a roadway with lane-changing areas. Based on the observation that, when changing its lane, a vehicle affects traffic on both its cu...

The critical density of a freeway link is subject to changes over time owing to such circumstances as environmental conditions (snow, rain, etc.) and traffic incidents. Because of the critical density’s impacts on the performance of some ramp metering strategies that make use of it as a threshold value for control action, it is necessary to trace the real value of the critical density. Hence, m...

We have developed the first hardware and software (intellectual property) metering scheme that enables reliable low overhead proofs for the number of manufactured parts and copied programs. The key idea is to make each design slightly different during postprocessing phase. Therefore, if two identical hardware/software designs or a design that is not reported by the foundry are detected, the des...
