Highway signs are a critical part of the roadway infrastructure, providing important information to drivers to assist in navigation, identify potentially hazardous roadway locations, and to remind drivers of safe operating practices. Ensuring that signs have sufficient visibility to the driving public is a key undertaking by transportation agencies such as NYSDOT.
This study compared the effectiveness of preservation treatments on pavement surface friction and investigated the long-term variation of friction using the data collected in the Specific Pavement Studies-3 (SPS-3) of the Long Term Pavement Performance (LTPP) program. The SPS-3 focuses on the effect of four preservation treatments (thin overlay, chip seal, crack seal, and slurry seal) on pavement performance under five design factors (traffic, precipitation, temperature, existing pavement condition, and subgrade type).
Public transit service provided by NJ TRANSIT is used throughout the state of New Jersey by a large number of persons to visit recreational activities. Such activities include beach-related recreation and amusement, sporting events, concerts, and various types of shows and other events.
In order to achieve an efficient transportation system, proper demand management strategies are more critical than increasing facility capacity. Previous studies suggest that most of the strategies have substantial impacts on traffic pattern and travel behaviors, but the effects may not be exactly the same as they were initially expected to be. This project focuses on assessing travel demand management strategies to enhance such understanding.
As cities become more congested and increasingly focused on sustainability, cargo cycles offer a potential alternative to motorized vehicles for local and last-mile goods delivery. However, few studies have examined this mode in the North American context. This project seeks to address this existing gap in research on cargo cycles/freight tricycles in North America and in New York City (NYC).
According to a comprehensive study conducted in 1998 by CC Technologies, corrosion to the US economy was $276 billion or 3 % of the 1998 GDP (FHWA-RD-01-156). From that amount, $121 billion was spent on corrosion control and $107 billion was spent on protective coatings alone. CC Technologies reported that better corrosion protection could save up 40% of that cost.
This report describes a Rutgers University project for the New Jersey Department of Transportation (NJDOT) designed to analyze the potential for closure of New Jersey landfills using dredge material from existing Confined Disposal Facilities (CDF).
Adaptive Control Software Lite (ACS-Lite) is a traffic signal timing optimization system that dynamically adjusts traffic signal timings to meet current traffic demands. The purpose of this research project was to deploy and evaluate the ACS-Lite adaptive traffic control system on a congested urban corridor in New York State (NYS). In this case, the Wolf Road Corridor in Albany, New York, was chosen.
Because of their inherent flexibility and low damping ratios, cantilevered mast-arm traffic signal structures are susceptible to wind-induced vibrations. These vibrations cause structural stresses and strains to develop in a cyclical fashion which can lead to reduced service life due to fatigue and, in extreme cases, full collapse.
