Dynamic modeling of the electric transportation network

– We introduce a model for the dynamic self-organization of the electric grid. The model is characterized by a conserved magnitude, energy, that can travel following the links of the network to satisfy nodes’ load. The load fluctuates in time causing local overloads that drive the dynamic evolution of the network topology. Our model displays a transition from a fully connected network to a conf...

Impact of port disruption on transportation network

Port, as a critical facilitator in international trade and logistics, plays a unique role in global supply chain activities. Maritime ports are exposed to many disruption sources such as natural disasters, labour strikes and terrorism. Disruptions in port can have a wide range of potential negative impact on its transportation networks; while sometimes also benefit other ports in close proximit...

Transportation planning for disasters: an accessibility approach

A methodology is developed in this paper for evaluating and enhancing the performance of urban transportation systems in the aftermath of a disaster. A performance measure is proposed for assessing overall and distributional impacts based on the concept of accessibility. The methodology is demonstrated with two case studies. The first focuses on passenger railroad disruption in the catastrophic...

Understanding the Impact of Transportation on Economic Development

The interface between transportation investment and economic development has broad ramifications that go beyond transportation’s basic purpose of moving goods and people from one place to another. Whereas there is no doubt that transportation is essential in the operation of a market economy, much still needs to be understood about ways in which an efficient transportation system can improve th...
