Creating complex congestion patterns via multi-objective optimal freeway traffic control with application to cyber-security

This article presents a study on freeway networks instrumented with coordinated ramp metering and the ability of such control systems to produce arbitrarily complex congestion patterns within the dynamical limits of the traffic system. The developed method is used to evaluate the potential for an adversary with access to control infrastructure to enact high-level attacks on the underlying freew...

Optimal traffic control in freeway networks with bottlenecks

We consider optimally coordinated freeway traffic control for networks containing bottlenecks with capacity drop. Due to the multitude of traffic jams, and the spatial and temporal relationships between control actions and traffic behavior, this coordinated control problem is not as straightforward as for local control. The order in which the measures are applied may be relevant, or it may be p...

Efficient Numerical Frameworks for Multi-objective Cyber Security Planning

We consider the problem of optimal investment in cybersecurity by an enterprise. Optimality is measured with respect to the overall (1) monetary cost of implementation, (2) negative side-effects of cyber-security controls (indirect costs), and (3) mitigation of the cybersecurity risk. We consider “passive” and “reactive” threats, the former representing the case where attack attempts are indepe...

Optimal structure of complex networks for minimizing traffic congestion.

To design complex networks to minimize traffic congestion, it is necessary to understand how traffic flow depends on network structure. We study data packet flow on complex networks, where the packet delivery capacity of each node is not fixed. The optimal configuration of capacities to minimize traffic congestion is derived and the critical packet generating rate is determined, below which the...
