Light Trucks and Highway Fatalities: The Role of Network Effects

Project Brief

Light trucks, such as sport utility vehicles (SUVs) and pickups, impose greater risks of injury and death on other motorists than do cars, while at the same time providing their occupants with increased protection against these risks relative to cars. In theory, these characteristics could combine to create a network effect: the more people who drive light trucks, the greater the propensity of a consumer to choose a light truck relative to a car (that is, as a means of protection against other light trucks on the road).

Robust Routing for Hazardous Materials Transportation with Conditional Value-at-Risk on Time-Dependent Networks

Final Report

New methods are proposed for mitigating risk in hazardous materials (hazmat) transportation, based on Conditional Value-at-Risk (CVaR) measure, on time-dependent vehicular networks. While the CVaR risk measure has been popularly used in financial portfolio optimization problems, its application in hazmat transportation has been very recently proposed. The CVaR models are shown to be flexible and general routing models for hazmat transportation, and be solved efficiently.

Robust Routing for Hazardous Materials Transportation with Conditional Value-at-Risk on Time-Dependent Networks

Project Brief

The Pipeline and Hazardous Materials Safety Administration defines hazardous materials (hazmat) as a substance or material capable of posing an unreasonable risk to health, safety, or property when transported in commerce. Hazmat accidents can result in significant injuries to the population and damages to the environment. It is therefore desirable that a decision maker considers both objective and subjective factors and makes route choices carefully but flexibly.

Study of Goods Movement through I-278 NYC and NJ

Final Report

The I-278 Intermodal Corridor is the term used in this project to define the interconnected network of roadway and railfreight facilities that arc between the New Jersey-New York connection at the Goethals Bridge and the Queens-Bronx connection at the Triborough Bridge, including the existing and proposed rail-freight connections across New York Harbor between Bayonne, New Jersey and Southwest Brooklyn.

Early Age Rutting Potential of Warm Mix Asphalt (WMA)

In summary, the term warm mix asphalt (WMA) refers to technologies and systems that allow for the substantial reduction in production and compaction temperatures of hot mix asphalt. The original intent of utilizing WMA was to provide better workability and compaction of asphalt mixtures at significantly lower temperatures. In addition, WMA was developed to reduce emissions and energy production usage and their associated production energy costs.

Underground Pneumatic Transport of Municipal Solid Waste and Recyclables Using New York City Subway Infrastructure

While Manhattan’s streets may be the most congested—and carbon-emitting—in the country, the subway system that runs beneath them offers an inspiring example of how efficiently—and with what minimal emissions of greenhouse gases—passengers can be transported. Although the collection and transport of municipal solid wastes produces only a fraction of the congestion and emissions on Manhattan’s surface, in absolute terms the hundreds of thousands of annual truck miles these wastes cause are nonetheless quite significant.

Eliminating Trucks on Roosevelt Island for the Collection of Recyclables and Commercial Waste While Significantly Improving Energy Efficiency and Reducing Land Requirements

The environmental and economic impacts of New York State’s waste-management system could be dramatically reduced by (a) decreasing the number of truck miles required to collect waste and (b) decreasing the demand for long-distance transport to remote disposal facilities.
