Developing a Strategic Sustainability Plan for New Jersey Transit

New Jersey has the third highest percentage of commuters that use public transportation, behind only New York and the District of Columbia. NJ Transit is the largest statewide public transit system in the United States covering more than 5000 square miles of service area. Given this tremendous expanse and scope, the role of NJ Transit in upholding superior environmental and sustainability standards cannot be overstated. ...more »

Drone-based hyperspectral imaging technique for monitoring pollution and corrosion

We often see plastic bags or other garbage hanging on trees, along the roadside, slipping down the storm drain, and floating in the ocean. There are over 51 billion pieces of litter on our nation's roadways, 4.6 billion of which are larger than four inches in size. Plastics takes 19 % of 51.2 billion pieces of litter on roadways nationwide. 1.4 billion beverage containers on our nation's roadways: Beer bottles: 30%; Soft ...more »

Methodology Development for Bicycle Parking Investment Prioritization

NJ TRANSIT rail stations operate as multimodal hubs, often with access to at least one other transit mode in addition to vehicle and non-motorized access. Over the past five years, select stations on the rail network have experienced significant increases in bicycle parking demand. This study will consist of three phases, with an end goal of developing a methodology for prioritizing locations of future bicycle parking ...more »

Developing High-performance Pervious Concrete for Multifunctional Pavement

Road is essential for our economy and way of life. According to the 2016 Report Card for New Jersey's Infrastructure, the overall rating for the road condition in New Jersey is D+, indicating that New Jersey's road is in poor condition. There is an urgent need to innovate the pavement materials to improve the road condition in a cost-effective way. Recent research shows that pervious concrete has great potential for ...more »

Plastic Roadways

From India and Scotland, to Texas USA, plastic additives are utilized in patching potholes, repairing cracks, and could be mixed with bitumen to create full paved roads. This action could help with a reduction of plastic waste, a decrease of material cost, a stronger durability with roads, and done without causing leeching or harm to the environment.

Bus Ridership Data Analysis System

Developing a comprehensive Bus Ridership Data Analysis System would allow NJ TRANSIT to better anticipate travel demand, more effectively ensure that all communities are provided equitable service, and better target its customer outreach efforts. Currently, NJ TRANSIT uses fare revenue as an indicator of passenger ridership. The agency also relies on passenger surveys to obtain samples of ridership demographics as well ...more »

Mitigation of Heat Islands

In the science of global warming, there is a term I have learned called, "Heat Island." It is where the large areas of dark surfaces, and heat generating facilities in cities creates a bubble of artificially high temperature; an island of heat. As reported in the article located at the link below, there is a viable solution coming out of Los Angeles. They are coating their streets in a light colored asphalt based sealant ...more »

Railroad Trespasser Sensors

Recent train wrecks and people getting killed by trains have been in the news, becoming a major headache for America's railways. The wrecks and rollovers might be mitigated if a way were found to make the railroad tracks "feel" the trespassers or blocking objects. The idea would work like this: 1) Person or object is stuck on the tracks or trespassing. 2) Sensors/ detectors lining the tracks, or cameras, detect the person ...more »

Lego-inspired Automated Construction - A New Paradigm of Accelerated Bridge Construction

Inspired by the Lego units as toys, we propose to construct re-configurable engineering structures using prefabricated standardized blocks. The blocks are designed for assembly of large-scale engineering structures through dry jointing schemes using construction robots. The blocks will be made of high-performance fiber-reinforced cementitious composites (HPFRCC) with high mechanical properties and long-term durability. ...more »

Developing Crack-free High-performance Concrete for Bridge Deck and Pavement by Internal Curing

The use of high-performance concrete (HPC) in bridge deck and pavement is increasing because of its enhanced durability and longer service life. The mixture design of HPC involves the use of relatively low water-to-binder ratio (w/b), supplementary cementitious materials (SCMs), and chemical admixtures. Securing high durability necessitates proper curing of the HPC to ensure adequate hydration of the cementitious system. ...more »

Strain-hardening Cementitious Composites for Resilient and Eco-friendly Infrastructure

Strain-hardening cementitious composites (SHCC) is a family of high-performance fiber-reinforced cementitious composites that have high tensile ductility and multiple cracking behavior in tension. Compared with normal concrete, the tensile ductility of SHCC is typically 300-500 times higher. Cracked SHCC has retained resistance to tension, and generates densely-distributed microcracks rather than a limited number of wide ...more »

Understanding the Needs of Current and Potential Bus Transit Riders

Conduct research to identify best practices used by transit agencies to better understand the needs of current and potential bus riders. The research should explore the survey methodologies used which could include telephone surveys, online surveys, face-to-face interviews, onboard surveys, public outreach events, interviews with local stakeholders or other innovative techniques to reach users, non-users, and former users ...more »

Effectiveness of LPIs in Reducing Pedestrian Crashes at Signalized Intersections on State Highways

Lead Pedestrian Intervals (LPIs) are utilized at signalized intersections to allow pedestrians a three to seven second head-start to enter the crosswalk before turning traffic may proceed. This allows pedestrians to better establish their presence in the intersection, improving their visibility and safety. A study exploring the potential effectiveness of LPIs on New Jersey state highways, and the considerations that ...more »

New Transit Model Needed

The classic model of a train stopping at different stations along its track is no longer feasible in a state as densely populated as New Jersey. Technology is now at a point where we can adopt a model that has been suggested for decades in different forms, but until recently, it was not technologically feasible. The electric car model of having the batteries and motors built into the floor of the vehicle would allow ...more »

Effect of Center Line Rumble Strip Installation on Pavement Longevity

The Federal Highway Administration encourages the use of center line rumble strips as a proven safety countermeasure for reducing head-on collisions and opposite-direction sideswipes. However, concerns have been raised by county engineers in the SJTPO region about the effect of center line rumble strips on pavement longevity. Roadways with center line rumble strips have been observed to deteriorate along the center line, ...more »
