Reverse transportation planning model by applying machine learning technic trending idea

Transportation models are used for predicting future traffic, especially in urban areas. Their traffic forecasts are applied to plan new infrastructures such as highways, bridges, new transit lines, and/or enhancing current public transportation modes. They use the specific areas' socio-economic data together with sample travel survey data to build a transportation model. The initially developed model usually is calibrated... more »

Test Sites to Determine BMP of Unmaintained Sites along Roadways trending idea

The state of New Jersey has a complex and interwoven roadway network that creates many areas needing maintenance. Although large swathes of areas are regularly maintained, often times there are small parcels or areas that are often forgotten or neglected for long periods. These areas wedged between ramps, under bridges, behind fences, or on a slope become breeding grounds for invasive plant species where the plant growth... more »

Evaluation of New Jersey Public Use Airports trending idea

New Jersey's airport system is one of the most unique and complex in the U.S. The State's diverse airports range in size from small general aviation airports with turf runways to Newark Liberty International Airport, one of the nation's busiest commercial airports. From Newark Liberty International Airport to the state's smallest public use turf strips, New Jersey's airport system must support all aspects of the State's... more »

Using computer simulation guiding heavy vehicles for traffic safety on roads trending idea

Using geographic information systems, artificial intelligence, and computer-aid-design to infer safety choices for heavy vehicle routing and scheduling methods. We are at the early edge of developing an information system for generating/assigning heavy vehicle trips in terms of time and space.

Heavy-vehicle routing choices could be managed aligned with job site schedule planning. It would thus be able to prevent neighborhoods... more »

Hydraulic Modeling for Climate Change Resiliency trending idea

Pilot study should be undertaken to look at the impacts of climate change on NJDOT's bridge assets in a watershed that includes riverine and tidal influences, and varying topography. The analysis should look at rainfall increases, based on the NJDEP's referenced Cornell model, and give NJDOT insight on the impacts to future flow increases anticipated in the context of studied FEMA streams. The precipitation increases... more »

SnowCATs - Snow Clearance Assistance Teams trending idea

PROBLEM:

Plowing snow from NJDOT roadway travel lanes during storms is the agency's highest priority to maintain mobility and access for emergency services. However, emergency plowing creates snow banks piled into corners of intersections, onto sidewalks and into bus stops and bus priority / shoulder lanes. Without post-snow-event clearance actions, these locations become impassable barriers that increase the risk of... more »

Extend Service Life of Concrete Bridge Decks with Internal Curing

Curing is a critical step in concrete pavement construction. Due to the large surface area to be covered, external curing methods normally do not provide concrete with necessary moisture conditions for long-term hydration. Insufficient curing often causes internal cracks or shrinkage cracks on the surface of the pavement. These early-age cracks not only hurt the strength, but also increase the permeability so that chlorides... more »

Pulaski Skyway Rocker Bent Rehabilitation

As a part of the ongoing Pulaski Skyway Rehabilitation project, one of the tasks include the rehabilitation of a traditional railroad style truss expansion device similar in function to the more commonly known pin and hanger mechanism, referred to in the original plans as 'Rocker Bents'. However, a key difference being that these members act in compression as opposed to tension. The original detail proved unsustainable,... more »

Corrosion Study

With most of the State's infrastructure in need of maintenance and repair, a main cause particularly on steel structures is corrosion. Corrosion which acts in several different forms results in section loss, which reduces capacity of the affected member. To better service the transportation industry, samples should be taken from bridges near or at the end of its useful service life and compare its as-inspected measurements... more »

Development of Low-Embodied Carbon Concrete Mixtures for NJDOT

The State of New Jersey has independently joined the Paris Climate Accords and uphold the goals of the Paris Climate Agreement. Per this agreement, an overall carbon reduction of 14% needs to be achieved within the United States. Concrete is responsible for around 8% of the world's CO2 production, mainly due to the production of portland cement. Therefore, finding methods to reduce the carbon footprint of concrete can... more »

Multi-Hazard Design of Highway Bridges

Civil infrastructure is vital to economic development and critical to response and recovery after extreme events. However, they are also quite vulnerable to natural and man-made hazards such as flooding, earthquakes, storm surge, fire and terrorist threats; especially highway bridges. Therefore, there is a need to move toward multi-hazard deign of bridges.

Multi-hazard approach to design of structures will require emphasis... more »

Development of Bus Collision Avoidance Warning and Automated Emergency Braking (CAWS/AEB)

Collision avoidance warning systems are available for cars and trucks to detect and warn drivers of potential forward collisions and automatically initiate deceleration and braking. These systems offer the potential to significantly reduce fatalities, injuries and casualty and liability expenses. However, more development is needed to apply them to buses.

In the five year period from 2015 to 2019, NJ TRANSIT reported... more »
