Innovative Roadway Light Source and Dye Combinations to Improve Visibility and Reduce Environmental Impacts

Final Report

Sky glow light pollution is caused largely by reflected light off of roadway and other surfaces. The authors investigated the feasibility of a system consisting of a specialized LED streetlight and a dyebased roadway surface coating that would reduce sky glow, but still provide adequate illumination of objects in the road. As envisioned, the streetlight would produce white light with narrow-band LEDs of red, green, and blue wavelengths.

Impact Assessment of the Regulation of Heavy Truck Operation

Project Brief

The main objective of this project was to evaluate the impact of New York State’s divisible-load permit system for heavy trucks in terms of benefits and costs to society. Under this system, New York State has allowed a fleet of approximately 12,800 power units to operate above the federal limits on gross vehicle weights and axle loads. The system has eleven permit categories corresponding to number of axles, weight limits, and statewide or downstate geographic area of operation.

Sensitivity Analyses of the Best Practice Model (BPM) in the New York Metropolitan Region (Part II)

Final Report

<p>New York Metropolitan Transportation Council (NYMTC), an association of governments, transportation providers, and environmental organizations, handles the metropolitan transport ation planning throughout New York City, Long Island and the Lower Hudson Valley. In the early 1990s, NYMTC developed a transportation model, the New York Best Practices Model (NYBPM),&nbsp; in response to federal regulations on surface planning, specifically the Intermodal Surface Transportation Efficiency Act (ISTEA) and the Clean Air Act (CAA).

Sensitivity Analyses of the Best Practice Model (BPM) in the New York Metropolitan Region (Part I)

Final Report

<p>Activity-based microsimulation models are gaining increasing attention from MPOs around the country. These models earn their reputation by having shown their theoretical superiority over the traditional four-step models. The NYBPM (New York Best Practice Model) model is one of a relatively few operating activity-based microsimulation models in the country and thus provides us a working platform to test their practical advantages over the traditional four-step models. We accomplish this goal by examining the sensitivity of the model in response to changes in the input.

Cement Hydration and Heat Exchange Modeling for Curing Process of Concrete Pavements and Bridge Decks at Early Stages

Final Report

This report, written by Gary S. Wojcik and David R. Fitzjarrald of the University of Albany, describes the field campaign and subsequent data analysis for the Route 30 bridge over the South Chuctanunda Creek in Montgomery County, NY. The two purposes of this work were 1.) to make more detailed measurements of the bridge environment than we have done in the past to better understand the energy budget of a curing concrete bridge and 2.) to provide atmospheric boundary conditions to a model of curing concrete.

Cement Hydration and Heat Exchange Modeling for Curing Process of Concrete Pavements and Bridge Decks at Early Stages-Brief

Project Brief

This project involved a field campaign and subsequent
data analysis for the Route 30 bridge over the South
Chuctanunda Creek in Montgomery County, NY. The
two purposes of this work were: 1) to make more
detailed measurements of the bridge environment than
we have done in the past to better understand the
energy budget of a curing concrete bridge and 2) to
provide atmospheric boundary conditions to a model
of curing concrete.
New measurements included direct sensible and latent
