Satellite-Based Bridge Inspection

Dr. Pietro Milillo (currently working with the Jet Propulsion Laboratory) is working on a method of performing bridge inspections using, "computer modeling and high-resolution satellite images to detect subtle shifts in a bridge's structure that could indicate that it's starting to fail." (as stated by Jaclyn Jeffrey-Wilensky in her article at https://www.nbcnews.com/mach/science/tragic-bridge-collapse-spurs-creation-new-space-based-inspection-method-ncna1028281... more »

Glowing Pavement Marking

Existing pavement markings are made of latex and glass beads, and they wear off quickly. When the road is wet or dark, pavement marking is hard to see. Low visibility is one of the reason more accidents happen on wet road or after dark. Pavement marking, when made of more durable material and inlay into the pavement, can last longer. Pavement marking, when combined with Fluorescent, Optic tube, UV LED, reflectors,... more »

Development of a Methodological Approach for Assessing the Performance of New Jersey Jug-Handles

The recent publication of the 6th Edition of the Highway Capacity Manual (2016) introduced a chapter on Ramp Terminals and Alternative Intersections that assesses the performance of Median U-turn, Restricted crossing U-turn and Displaced left-turn intersections. Despite the widespread use of jug-handles in New Jersey and elsewhere, the HCM does not provide a methodology for the performance of jug-handles. The operational... more »

American Dream Mall and Meadowlands Sports Complex Travel Study

The Meadowlands Sports Complex and American Dream Mall are two major entertainment and employment centers in Northern New Jersey. Located in East Rutherford, this combined complex is the location of MetLife Stadium, the Meadowlands Racetrack, and the newly opened American Dream Mall. As such, it is an area where multiple individuals with disparate interests come together from the entire New York Metropolitan Area and... more »

Better Understanding how Women and Children Travel using NJ TRANSIT

According to the National Household Travel Survey, women account for 55% of transit riders in the US. LA Metro's "Understanding How Women Travel" study found that women use the Metro system more. Women are a larger portion of the population. Women have different travel patterns than men and have different commute demands. Similar research by Transport for London's series of reports "Understanding the Travel Needs of... more »

Evaluation of Operations, Maintenance, & Infrastructure Requirements for Battery-Electric Minibuses trending idea

New Jersey is on a path to a carbon-neutral future under the policy direction of Governor Murphy. Carbon emissions of motor vehicles, including passenger cars, trucks, and buses contribute to climate change, and efforts are being made at NJ TRANSIT to evaluate alternative bus power systems that reduce or eliminate such emissions. While great attention is given to heavy-duty transit bus power systems, less is known about... more »

Vertical Cities – Reduce need for transportation and fuel consumption

In order to fit the ever increasing population into the same size areas, we have been growing our cities vertically for decades. However, we are still doing so based on the same old two dimensional zoning structure. We should modify the zoning laws to allow for vertical cities. Construct city high-rise buildings with multiple zones inside. So people can move from residential to commercial, to park, to school zones... more »

Smart Unmanned Surface Vehicles (drone boats) for scour management of Bridges in New Jersey

Hydraulic failure of bridges because of scour has been considered to be the leading cause of failure of bridges all across the country. Although NJDOT has been managing scour through inspections and countermeasures, accurate assessment of bridge foundation for scour and scour countermeasures is still a major challenge. Recent advances in autonomous robotic technology can be utilized to develop a smart and innovative... more »

Innovative Standardized Connection Details for Highway Signs and Signal Support Structures

In service fatigue fracture of highway signs and signal support structures due to wind induced oscillations is the primary concern for cost-effective life cycle performance of these structures. Recognizing the impact of potential life and property damage from structural failures and economic burden of inspecting, maintaining and replacing the sheer volume of these structures in the inventory, the American Association... more »

Innovative Cost-Effective Standard Decks for Movable Bridges

Of the 50 states New Jersey ranks third for the number of movable bridges. With an average age of approximately 40 years, more than 50 percent of these bridges are structurally deficient, mainly due to their bridge decks. Many of these bridges, whether state or locally owned, are subjected to significant average daily truck traffic (ADTT). Because of their condition and their location on significant commercial routes... more »

Quantifying the Effectiveness of Bridge Preservation & Maintenance

Understanding the effectiveness and optimal timing of bridge preservation, maintenance and repair activities are pivotal for bridge asset management. Although extensive resources are dedicated to these activities annually, their impact on the long-term performance of bridges is not well documented and/or understood. One reason for this lack of understanding is the sheer complexity involved. The effectiveness of bridge... more »

Idea 1, "Project Gain"

In Idea 1 (originally titled "Project Gain"), I propose new concepts for roadway intersections that may provide improved performance over conventional intersections. Specifically, the concept intersections blend together certain key elements from different kinds of existing intersections in order to create alternative options in traffic signal control. With their unique design, operation, and usage, the concept intersections... more »
