Improved Customer Service and Automated Route Verification for the Issuance of Special Hauling Permits by the NYSDOT (Excerpts)

<p>This report presents a design for an electronic permit issuance system for overdimensional and/or overweight vehicles with nondivisible loads. The system has been designed in collaboration with, and for use by, the New York State Department of Transportation (NYSDOT), but the major elements of the design (if not the specific details) should be transferrable to other states or agencies.</p>

Analysis and Evaluation of the Physical Characteristics of Hot Mix Asphalt Using Crumb Rubber Modifier (Excerpt)

State-of-the-art technology is available which incorporates shredded scrap tire rubber known as crumb rubber modifier (CRM) as a modifier for asphalt cement in paving mixtures. CRM is the general term to describe all rubber particles obtained from the shredded of discarded tires which are reduced up to a size of 6.35 mm. Two technologies are most commonly used to incorporate crumb rubber in asphalt pavement applications, namely, the wet and dry process.

OPENING-MODE CRACKING IN ASPHALTPAVEMENTS: CRACK INITIATION AND SATURATION

<p>This paper investigates the crack initiation and saturation for opening-mode cracking. Using elastic governing equations and a weak form stress boundary condition, we derive an explicit solution of elastic fields in the surface course and obtain the energy release rate, so that opening-mode cracking initiation can be determined by fracture energy criterion. Interestingly, the longitudinal stress between such cracks along the surface undergoes a transition from tensile to compressive with increasing applied tensile loading, which implies crack saturation.

Comprehensive Survey of Emerging Technologies for the New York Metropolitan Area

Professors Satish Ukkusuri and Jose Holguin-Veras of Rensselaer Polytechnic Institute (RPI), as a result of an RFP process through the UTRC, have been selected by a selection committee to conduct an assessment of the emerging and promising technology that is likely to impact transportation in the NYMTC region.

Comparative Evaluation of Deflection and Wave Propagation Nondestructive Testing Methods for Pavements: Implications for Implementation at State and Local Levels (Excerpts)

<p>In New York City, as in other highly urbanized areas, several factors make it too difficult to apply pavement management systems methodology in the traditional way. Two of those factors are: underground utilities and utility cuts; together, they are the two most significant life-limiting factors for NYC pavements. Non-Destructive testing (NDT) techniques such as the Falling Weight Deflectometer (FWD) have been successfully used to evaluate the conditions of rural pavements.

Dedicated Commercial Transportation Corridor

As the world economy continues to grow, and the law of comparative economic
advantage takes on greater significance at both the national and regional level, the
importance of having efficient and effective freight transportation systems continues to
increase. Local economies are no longer immune, or insensitive to shifts in trading patterns
and alliances on the global level. A region that is strategically placed geographically, and
well-equipped from a freight transportation system standpoint, will profit significantly from

Collaborative Exploratory Research on the Anticipatory Route Guidance Problem

Advanced traveler information systems (ATIS) attempt to provide drivers with data intended to help them make better travel decisions. Messages may be available to all drivers (for example by radio or television broadcasts) or only to some: for example, those who pass near a particular infrastructure (such as variable message signs or VMS) or who have special receivers in their vehicles. Drivers, of course, may react to the messages in any way they choose.

Transportation Choices and the Future of the New York City Economy

The vitality of New York City?s economy is highly dependent on a modern, efficient mass transportation
system that connects the city?s current and future centers of employment to the regional labor pool. The
availability and adequacy of mass transit are major factors in business location decisions, driving demand
for commercial real estate and dictating patterns in job growth. Despite their critical importance to business
and economic development, major investment decisions on transportation projects are typically made without

Characteristics of Traffic Flow in 55 and 65 mph Speed Limits

Speed limits have been introduced for many reasons, e.g., to reduce gas consumption, to reduce the frequency and severity
of crashes, and in some cases to reduce noise. The objective of this research effort was to conduct a literature review to
assess the effect of increased speed limits on limited access roads regarding safety, travel speeds, and other unanticipated
impacts including shifts in lane distribution, traffic diversions, and spillover effects. Following are the conclusions:

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

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.
