Speed and Design Consistency of Combined Horizontal and Vertical Alignments in Two-Lane Rural Roads

One of the most important equations in highway design is the formula for the minimum radius of horizontal curve which considers the design speed of the highway, the superelevation, and the side friction factor. Traditionally, differences in the highway vertical alignment features, which are prevalent at areas with rolling and mountainous terrains, are not considered in this part of the design process. Past research has indicated that drivers perceive horizontal curves differently when compared with highway sections in which both horizontal and vertical curves overlap.

Promoting Transportation Flexibility in Extreme Events through Multi-Modal Connectivity

Extreme events of all kinds are increasing in number, severity, or impacts. Transportation provides a vital support service for people in such circumstances in the short-term for evacuation and providing supplies where evacuation is not undertaken, yet, transportation services are often disabled in disasters. Nationwide and in New York and New Jersey record-setting weather disasters have occurred and are expected to continue. Disadvantaged populations are particularly vulnerable.

Potential Tidal Power for New Jersey

High-resolution simulation is made to model tidal energy along the coastlines of New Jersey (NJ) and its neighbor states with an unprecedentedly fine grid. On the basis of the simulation, a thorough search is made for sites for tidal power generation, with special attention to locations near transportation infrastructures, considering factors such as power density, surface area, water depth, and environmentally sensitive zones, and it also examines effects of sea-level-rise (SLR).

Investigation of the I88 Carrs Creek Geofoam Failure

The Carrs Creek culvert collapsed during the Mid- Atlantic States Flood in June 2006. Rapid construction with geofoam fill enabled partial reopening of I88 by Labor Day. Soon after opening, excessive settlements developed and the geofoam was replaced with lightweight aggregates and I88 was again re-built. Figure 2 Excessive settlement and removal of the geofoam fill.

Nighttime Highway Construction Illumination

The nighttime driving environment, consisting of roadway illumination, signs, vehicle lighting and markers, delineators and flashing lights, can be complex or even confusing for both pedestrians and drivers. The nighttime construction environment is even more complex and even chaotic because of the added presence of workers, construction equipment and bright lights (which are sometimes flashing). Work zones at night often involve changing conditions and new traffic patterns that are unfamiliar to drivers.

Offshore Wind Development Research

The study addresses all aspects of Offshore Wind (OSW) development. This includes identifying vessel types, vessel installation methods, needs and operating characteristics through all phases of OSW installation, construction, operations and maintenance. It also identifies regulatory or legislative requirements and/or other road blocks to the use of particular vessels. The study identifies a number of New Jersey’s staging ports based on port selection criteria.
